In this study, the causality relationship between financial development, commercial openness and economic growth was investigated for 15 emerging economies over the 2002-2016 period. A fundamental question of whether financial development and trade openness have a significant impact on growth, particularly for emerging market economies, is a matter that needs to be addressed and discussed. The main purpose of this study on financial development is to investigate any existence of causality between commercial openness and growth, and then to determine the impact of this causality, if any.For the purpose of the study, the existence of a causality relationship between the series was analyzed with the Dumitrescu and Hurlin (2012) causality test, which takes into account heterogeneity and produces reliable results in case of cross-sectional dependence. In addition, Kónya (2006) panel causality analysis was conducted in order to reveal the results by country. In today’s world, due to increases in globalization, international trade levels and degree of financial integration, cross-sectional dependence should be taken into consideration. As in the global financial crisis that emerged in 2008, the economic shock in any country affects other countries differently. Therefore, it is necessary to test whether there is a horizontal cross-sectional dependence between the series before the analysis, since the results obtained in the analyses performed without considering the cross-sectional dependence will be deviant and inconsistent.&nbsp;The empirical studies in the literature generally use the ratio of private sector loans to GDP, which are two measures of financial development, and the ratio of capital market capitalization to GDP. However, addressing financial development with only these two variables narrows the scope of financial development. In this study, the financial development index prepared by the IMF was used in order to overcome this deficiency. The index shows the level of development of financial institutions and financial markets in terms of depth, reach and efficiency.There is a relatively short history of financial development and trade openness statistics that can be used in multi-country studies. Therefore, the study period was determined as 2002-2016. In addition, due to a lack of data, the horizontal section size of the data set is restricted to 15 countries. These issues constitute the main limitations of the study.The empirical findings are made of three parts. In the first part, there is the horizontal section dependence and homogeneity test, in the second part, the unit root test, and in the third part, causality tests are presented. According to our results, the horizontal cross-section dependence and slope coefficients are heterogeneous in series and model. This means that changes in each of the 15 emerging economies have an impact on other countries. In addition to having horizontal cross-sectional dependence in series and model, the heterogeneity of slope coefficients necessitates that both problems should be considered in unit root tests. For this reason, the Smith et al. (2004) panel boostrap unit root test considering heterogeneity and cross-sectional dependence together was applied. According to the results of the unit root test, the FDI variable contains a unit root. When the difference of the series is taken, it becomes stagnant. In this sense, it is seen that FDI series I (1) carries the process.The Dumitrescu and Hurlin (2012) causality test results showed that there is no causal relationship between financial development, commercial openness and economic growth. In the country-based results, the Kónya (2006) findings of causality generally coincide with the results achieved for the overall panel. Theer was one different result: in 5 countries (Colombia, Malaysia, the Philippines, Russia, and Turkey) financial development causes economic growth. The findings show that economic growth, commercial openness and financial development develop independently of each other. The absence of a causal relationship between the variables implies that the neoliberal commercial and financial liberalization policies, which were largely consecutively implemented after the 1980s, failed to achieve external growth.

Recently, the tourism sector has started to become an important sector for the economy of the countries. Sustainability of economic growth is one of the most important targets to be achieved for countries. When the economic growth of countries enters a systematic stalemate in certain periods, the tourism sector is seen as an alternative solution to overcome this dilemma. The reason why countries have increased the importance they attach to the tourism sector in recent times includes not only economic but also political, cultural and social reasons. Cultural, social and economic interactions between countries can be realized through tourism activities in the most effective way. With the increasing importance of the tourism sector in the economy, the number of studies examining the place of tourism indicators in the economy has increased. In this context, econometric analysis of tourism related indicators in the determination of tourism policies can draw a road map for decision makers. The course of tourism income over time attracts the attention of academicians and decision-makers. Because the course of this variable over time gives strong ideas for making predictions and decisions about the future. By using the previous period values of tourism income series, tourism incomes in the future can be predicted or the changes that will be made in tourism incomes by tourism investments can be estimated by econometric modeling. However, in order for the predictions and model estimations to yield reliable results, the average and variance of the tourism income series over time should remain constant, that is, it should be stable. Otherwise, the predictions made using the non-stationary tourism income series may be wrong and the estimation of the relationship between the tourism income variable and other variables may be false. In order to avoid these stalemates, the stagnation of the tourism income series should be examined to see whether the effects of sudden shocks on tourism incomes are permanent.&nbsp;In this context, this study, Turkey’s tourism incomes series of monthly time series properties have been previously studied using fourier stationarity test used not for tourism income series. In the studies examining the stagnation of the tourism income series, it is seen that unit root tests, which make seasonal adjustments, are generally used (Kulendran &amp; Wong, 2005; Nikolaos, 2008; Hepkorucu &amp; Doğan, 2019). Or, unit root tests of tourism series were used to examine structural changes using dummy variables (Narayan, 2005; Lean &amp; Smyth, 2008; Lee &amp; Chien, 2008). However, in cases where the number and location of structural changes are not known in the course of time, the use of dummy variables or using only seasonally corrected unit root tests may give unreliable results regarding the unit root process of the series. Fourier unit root tests, which allow accurate estimation of structural changes even in cases where the structure and location are not known, have shown strong results in the process followed by the data. Therefore, in this study, the unit root process of the tourism income series was examined by the stationarity test using fourier functions. The fourier stationarity test used in this study was performed by Becker et al. (2006). This stability test proposed by Becker et al. (2006) is an extension of the stability test developed by Kwitkowski et al. (1992) with fourier functions. In the Fourier KPSS stationarity test, structural changes were taken into account by using the Fourier function. The changes in the series can be predicted precisely by Fourier functions. In this study, Turkey’s stability characteristics of the data for the years 2012-2019 monthly tourism income variable is tested using fourier KPSS said stability test due to the strong features. According to the results of the KPSS Fourier stability test, the appropriate frequency for Turkey’s tourism serial number is calculated as 1. For the significance of Fourier terms, the F test statistic was calculated. Becker et al. (2006) ‘s study by comparing the critical values of the fourier terms were found to be significant. In this respect, it can be said that it is appropriate to use the fourier terms in the data creation process of the KPSS model used in stasis testing. Since the obtained Fourier KPSS test statistic was smaller than the critical values, the basic hypothesis could not be rejected. Turkey’s observed monthly data for the period 2012-2019, it has been concluded that there is stationary. The results obtained with this series is that Turkey’s tourism income stationary for the period studied. In other words, the effect of incoming shocks was temporary. This means that, in studies for Turkey and the policy decisions taken, predictions to be made by looking at the tourism income serial and model predictions will give reliable results.

The question of this study, which started in primitive society, and continued within the structure of slavery society, developed structurally in the framework of feudal society and then completed its evolution with the professionalization it experienced in the process of the industrial revolution. In recent years, the phenomenon of working with developing technology has taken on a modern form and has become visible in different forms until today. When the development of working life is taken into consideration, it is seen that employment diversity increases. This development and change takes place in a way that meets the needs of employees and employers as well as meeting the requirements of the era. While on the one hand the elasticity of employment emerges in different types, on the other hand it raises some problems for the employer and for the employer.&nbsp;Today, technological developments, increasing production diversity, improving transportation opportunities, increasing income level and social welfare have accelerated the formation of the global market structure. Meeting the increasing competition as a result of globalization has pushed enterprises to use scarce resources more efficiently. In order to solve these problems, business owners and writers who are conducting academic studies have constantly tried to find new solutions and develop new management approaches. In this context, outsourcing, which can be defined as transferring the activities that can be realized within the enterprise to an external supplier, is one of the strategic management approaches applied by many enterprises.With the development of technology and the increase in communication opportunities, competition has gained prominence, economic fluctuations are interacting all over the world, and efforts to create flexible organizational structures that can adapt rapidly to changes have led to enterprises to apply new management techniques. One of these methods is the “outsourcing” approach. Outsourcing can be defined as a management tool that enables enterprises to specialize by focusing on basic talents, to use time and resources in the most efficient way, to adapt rapidly to technological changes and to gain cost advantage in highly competitive markets.In general, outsourcing is used for the main reason of enabling small or large enterprises to continue, be it in the service sector or the production sector, thus making a profit and making their lives sustainable. However, it is not easy to realize this goal because of rapid changes and other developments in the world. In this process, the customers’ product or service alternatives are particularly easily accessible, and businesses keep customers while achieving efficiency in order to continue with a number of methods of doing business. Therefore, outsourcing is seen as one of the modern management practices in which companies apply to in order to achieve their ultimate goals. However, contrary to this general view, the cost element is not the only most important reason for outsourcing. In addition to reducing costs, factors such as&nbsp;developing the core capabilities of the enterprise, reducing and spreading risk, ensuring redistribution of resources, following technology and improving quality can be mentioned as other reasons for outsourcing.In order to achieve their goals, businesses apply to the skills of their employees in almost all of their fields of activity, and initiate a new approach with this new management approach. The application has now evolved into receiving services from other businesses according to their main fields of activity, with the main business of the enterprises, in other words the jobs they are competent with their competent human resources and other jobs (food, cleaning, security etc.). However, the fact that enterprises receive services from other enterprises through outsourcing does not mean that they ignore other fields of activity. This is because the behavior of employees employed in these areas has more or less impacted on organizational success. In other words, the organizational commitment levels of the employees also affect the productivity level. It is also known that human resources, which feel a sense of belonging to their organizations, strive for more organizational purposes than those who lack the sense of belonging, and they benefit from and worry about their organizations. In addition, these employees are successful in teamwork, motivating others and developing good relations with their colleagues. It can be clearly said that this is an important issue that enterprises cannot ignore.Individuals employed in the context of outsourcing face some problems in their working life. Individuals continue to carry out their business with the disadvantage of not being a permanent staff member of the enterprise where they work. In this context, the employer follows some policies in order to increase employee motivation and to make employees more productive. The most important of these are career and talent management practices. In this study, the approaches of career and talent management practices towards individuals employed within the scope of outsourcing are measured along with their effects on motivation and performance.

As a result of the convergence hypothesis that the growth rates of developing and underdeveloped countries will be higher than those of developed countries, underdeveloped and developing countries will catch up with developed countries. In other words, the real gross domestic product of all countries will be equalized after a certain period of time. This idea is basically based on the law of decreasing yields. As a result of the capital increase of developed countries, which have reached the saturation point in terms of capital, the output increase rate is below the output increase rate as a result of the capital increase of underdeveloped and developing countries, which are insufficient in terms of capital. The basis of the convergence hypothesis is based on Solow (1956). Until Solow’s work, an acceptable theoretical explanation could not be given to this phenomenon, which was voiced by many theorists prior to Solow. The basis of the convergence hypothesis is based on Solow (1956). Moreover, most of the growth models are directly or indirectly based on the Solow model. There are multiple types of convergence tested in the literature. Earlier models did not distinguish between old and new technology, and looked at both old and new technology with one vision. The introduction of technological progress means that there is a difference in the efficiency of old and new technology. Thus, the model means that only physical capital accumulation cannot bring about growth per capita or increase the amount of production. In particular, given a microeconomic specification of technologies and preferences, the per capita output in an economy will approach the same level, regardless of initial capital (Timakova, 2011). When comparing different economies, it means that for economies with the same technologies and preferences, the difference in production per capita will be temporary.The Solow growth model is the first to present convergence. It has deeply influenced the way economists conceptualize long-term relationships between macroeconomics. According to this hypothesis within the neo-classical growth theory approaches, the income of the less developed countries will reach the level of developed countries after a while. That is, the exact definition of convergence is to achieve the same fixed income level. Convergence hypothesis studies generally use external theory (Rivas ve Villarroya, 2017). Because the concept of convergence emerged, if different countries have the same preferences and technology, it can be said that the poorer countries tend to grow faster than the rich countries, especially in the presence of accumulated factors, particularly the decrease in marginal returns in capital use. Each country will reach its own stable state, but the differences in the per capita income will be reduced. When the rich and poor countries reach the same fixed income level, another possible solution can be seen. The hypothesis of convergence of incomes of underdeveloped countries to incomes of developed countries is a hypothesis frequently tested in the literature. Different types of convergence hypothesis can be tested in terms of econometrics. In this study, the convergence of annual income series of the EU member countries, covering the period of 1960-2018, was examined and the stochastic convergence hypothesis, one of the convergence types, was tested with panel unit root tests based on SUR models. The ADF and KSS panel unit root tests based on SUR models. The ADF and KSS panel unit root tests are second generation panel unit root tests. The ADF and KSS panel unit root tests take into account the cross-sectional dependency and allow for an explanation of each unit separately. In this study, using SURADF and SURKSS unit root tests, the convergence status of the EU member countries to the group average of the EU was examined, and results were given about whether the convergence hypothesis is valid for each country separately.

In this study, using logistic regression analysis and artificial neural network techniques on the data of 85 countries for 2017, the factors that were taken into account by Moody’s credit rating agency while determining a country’s credit ratings were determined, and the countries were divided into classes according to investmentability based on the granted credit scores . Within the scope of the study, the data set for year 2017 was taken from Moody’s official website. Moody’s had organized the data under four main headings, which included economic structure and performance, government financing, external payments and debt, monetary-external vulnerability and liquidity indicators. The data set, which included a total of 138 world countries, had been reorganized under the headings of economic structure and performance, state financing, external payments and debt to form the largest data set with common variables. Then, lost observations and extreme values were excluded from the analysis and a final data set consisting of 85 different countries was created . Here, it is also considered that the sample size should be at least five times the number of variables observed. According to studies in the literature 13 independent variables (Per capita GDP, Real GDP, Inflation, Gross Domestic Savings / GDP, Economic Gap, Government Revenue / GDP to Government Expenditures / GDP, General Government Primary Balance / GDP, General Government Debt, External Payments and Debt, Real Effective Exchange Rate, Current Account Balance / GDP, Net Foreign Direct Investment / GDP) are determined as Official Forex Reserves. For the dependent variable, a two category dependent variable was determined as Y = 1, meaning investment can be made, and Y = 2, meaning investment cannot be made , by making use of the investability level determined by Moody’s for long-term credit rating. Missing observations were not included in the analysis and contradictory observations, namely Luxembourg, Ecuador and South Africa, were excluded from the data set. After this, logistic regression analysis and artificial neural network statistical analysis methods were applied to the data set. Logistic regression is one of the alternative techniques that can be used in cases where the dependent variable is categorical as in socio-economic issues. According to the results of the logistic regression application, while the total correct classification rate is 90.6%, according to the predicted results, the correct classification rate of noninvestable countries is 87.9% and the correct classification rate of investable countries is 92.3%. Artificial neural networks are computer-based systems that are developed with the inspiration of the neurons of the human brain and do not require traditional skills. In other words, artificial neural networks are computer networks that try to simulate the neural cell (neurons) networks of the biological central nervous system (Yegnanarayana, B. 2009), (Öztemel E., 2003). In the application of artificial neural networks, the data set containing a total of 85 observations was randomly divided into 2 sets as training data containing 69 observations and test data containing 16 observations. As a result of the application, the training data accuracy rate was found to be 0.88 and the test data accuracy rate was found to be 0.56. In addition, the area under the ROC curve for the training data was 0.90 and the area under the ROC curve for test data was 0.61. A value close to 1.00 indicates a good classification, while a value of 1.00 indicates an excellent classification. In this study, two different methods were used with the most up-to-date data and a sample representing all world countries. Based on the literature review, it was observed that inflation, financial openness, per capita income, technological development, public income, public expenditure, borrowing, current account balance, democracy, adoption of laws and order and less corruption were most effective in granting country credit ratings. Parallel to previous studies and in addition to the application of logistic regression analysis, the most important factors determining whether countries can be invested in or not according to the 2017 country credit rating are GDP, Inflation, General Government Primary Balance / GDP, General Government Debt, Foreign Payments-Debt and Official Forex Reserves. According to the results of the analysis, it was observed that the correct classification rate of the logistic regression model is 90.6% and that of the artificial neural network model is 88%. Also in terms of credit scores it was concluded that Turkey was included in the list of non-investable countries.&nbsp;

Uncertainties and risks have increased within supply chains that are becoming more complex with globalization. As a result of this situation, enterprises are implementing risk management activities to reduce or eliminate the effects of the risks. The supply chain performance evaluation system represents a formal and systematic approach for companies to monitor and evaluate the supply chain performance. Modern performance measurement techniques include many performance measurement criteria under the main criteria of “efficiency”, and “efficiency” which will be more beneficial in the long run. The concept of risk is defined in the literature as the likelihood of a situation that may lead to loss or damage. The difference between the concepts of risk and uncertainty is that it is given together with the probabilities of possible events that may occur in the future. Supply chain risks are examined under the titles of demand risks, supply risks, logistics risks, IT risks and environmental risks. Risk management in the supply chain, is defined as “management of supply chain risks through coordination and cooperation among supply chain stakeholders to ensure efficiency and continuity”. It has been determined that failure to manage supply chain risks effectively can have serious negative consequences for companies. These risks include many factors such as reduced product quality, damage to equipment and materials, delays in delivery times, and loss of reputation among customers, suppliers and the public. The main purpose of supply chain risk management is to define the sources of risk and identify what causes the risks, and to create a model for analyzing the possible effects on the enterprise when risks occur. It should also analyze risk sources, and determine the likelihood of these risks and provide an appropriate solution to mitigate their impact. One of the main objectives of supply chain risk management is to minimize the possibility of risks occurring and to prevent situations that may result in waste of raw materials, production errors and high material losses before they occur. Firstly, a literature review has been done on supply chain performance, risk in the supply chain and objectives of risk management within the scope of this study. In this research, the relationship between supply chain risk management activities and business performance of enterprises is examined. In this context, supply chain risks and the effects of risks have been tried to be determined, and the effect of applied risk management activities on business performance has been investigated. Punniyamoorthy, Thamaraiselvan and Manikandan’s scale (developed in 2013) to measure “supply chain risk types”; and for “the supply chain performance” evaluation, the scales from Tao’s 2009 study were used in this research. During the data collection process, a total of 369 questionnaires were applied to enterprises operating in Istanbul,&nbsp;and the data obtained were analyzed. When the companies participating in the research are examined; 165 companies (46.6%) are active in the textile sector. While the number of companies operating in the service sector is 48 (13%), 25 companies (6.8%) are in logistics and 22 companies (6%) are in the food sector. Other than this, 100 enterprises (28.2%) operate in many different fields, such as construction, automotive, health care, and 9 of the participants left this question unanswered. As a result of the analysis, it was found that the factors related to supply, logistics, data processing and environmental risks were highly reliable, and the demand-based risks scale was found to be very reliable. As a result of analyses, it was concluded that risk management activities related to procurement and data processing risks positively affect the instutional performance, and no statistically significant effect was found for demand, logistics and environmental risk management activities. Finally, it has been determined that controlling the risk factors arising from the supply and data processing risk will contribute to the improvement of the supply chain performance of enterprises. Considering all these results obtained from literature review and researches conducted on the supply chain management in risk management and performance issues; risk management activities have an impact on the supply chain performance and, therefore, on the overall performance of the enterprise. For this reason, in today’s business life, where competition conditions are getting more and more difficult day by day, it can be stated that risk management is critical for enterprises to create an effective and efficient supply chain and to maintain their assets successfully.

Risk and return are the two most important parameters in stock investment. Rational investors are expected to prefer the share with the highest expected returns when their risks are the same, and they are expected to prefer the share with the lowest risk when their expected returns are equal. Risk of a financial asset can be defined as the possibility of losing money, that is, the probability that actual results differ from expected results. Therefore, risk is measured based on the volatility of the return measured by variance or standard deviation. The risk of stock may result from either external factors such as economic, geopolitical, and financial factors, or companyspecific internal factors. Systematic risk is inherent to the economy and /or market, and is generally assumed as being difficult to avoid. On the other hand, unsystematic risk is the risk that is related to company, and it is assumed as diversifiable. Since unsystematic risk is diversifiable, finance theory is focused on systematic risk. After Markowitz and Capital Asset Pricing Model (CAPM), systematic risk is measured by beta which is a measure of the volatility of a security or portfolio compared to the market as a whole.Financial ratios are also important in analyzing the health and success of a company. Generally, by ratios analysis, we shed light on liquidity, profitability, growth, financial structure, operational performance, and market situation of the company. Since these ratios are the key factors in determining the performance of a company, they should also play a role in the riskiness of the company. Therefore, we choose the Beta coefficient, as a proxy for systematic risk; and current ratio, ratio of total debts, cash-to-cash cycle, return on equity, and market value/book value to represent the different dimensions of performance.CAPM is based on a rational investor who constructs an optimum portfolio. However, Kahneman ve Tversky (1979)’s Prospect Theory showed that investors may not be so rational, and they generally decide based on some psychological factors called heuristics. These biases also affect our behaviors differently in the case of positive and negative situations.The aim of this study is to analyze the effect of financial ratios on the systematic risk of the companies listed in the Non-Metallic Mineral Products Sector Index of Borsa Istanbul. We used quarterly data of 15 companies for the period of 2005Q1- 2019Q4. Based on findings of behavioral finance the effect of positive and negative movements of financial ratios on Beta coefficient may be asymmetric. Therefore, Panel Non-linear Autoregressive Distributed Lag (Panel NARDL) model developed by Shin et. (2014) seems to best fit our study purpose. The NARDL searches whether the asymmetric relationship between financial ratios and systematic risk exists or not; if the asymmetric relationship is found, what is the direction and size of the relationship. It is important for all stakeholders to identify the factors and their directions that affect risk. The short and long-term asymmetric effect of the increase and decrease in financial ratios on risk is reviewed by the Panel NARDL model. Panel NARDL model can be used for small samples, and it allows to capture the cointegration dynamics which cannot be determined by other linear and nonlinear cointegration methods.Results of the study showed that an asymmetrical relationship was found between risk of companies and current ratio, cash-to-cash cycle and market value/book value in the long term; but no asymmetrical relationship is observed between risk and return on equity (roe) and total debt ratio. On the other hand, s symmetric risk-roe and risktotal tebt ratio relationship is observed between variables. In the short run, there was no asymmetrical relationship between risk and financial ratios. The achieved results are important in explaining the factors that effect stock movements.&nbsp;

The relations between economic growth and foreign trade have been widely investigated in the econometrics literature. These relationships can be evaluated using causality analysis, the starting point of which is often considered Granger’s (1969) study. The study provides the traditional definition of causality. The Granger causality relationship is obtained from the whole sample. This means that the effects of social, economic, and political shocks cannot be expressed clearly when the causal relationship between variables is evaluated. Therefore, even if structural changes have occurred in the interval of the sample, it may not be possible to identify these changes in the causality relationship.When structural changes impact the value of the variables, methods that help identify these changes should be used. Therefore, this study evaluates two different time-varying causality methods. The first is the time-varying parameters (TVP) causality. According to the TVP method, the effect of structural changes on parameter stability should be evaluated. For this, a joint null hypothesis is used. The joint null hypothesis is tested such that both the parameters are stable and there is no causal relationship. The other method is the recursive evolving window (REW) causality. In the latter method, structural shocks can change the causality relationship, and therefore, causality should be examined in sub-samples.This study evaluated the causality relationship between economic growth, export growth, and import growth in Turkey. First, it examines the relationships with the traditional Granger causality analysis. The study found a bidirectional causality relationship between economic growth and import growth in the sample. This result indicates that, in fact, increasing income levels cause more attention to be given to information and technology in imports. Further, there is an increase in purchasing power and input requirements.The causality analysis of the whole sample indicates a uniform relationship. The opposite conclusion was based on investigating the effects of structural changes over time. The authors conclude that Turkey should closely follow the events that affect the commercial activities—both within the country and in neighboring countries— to maintain balance between foreign trade and economic growth. Therefore, it is inevitable for Turkey to be affected by the results of structural changes. Therefore, the results of structural changes are the prime subject of this study, and the changes in the causality relationship were observed with time-varying causality methods.Further, this study shows the stability of the parameters while examining the timevarying causality relationship. For this reason, the results of time-varying causality relationships are presented by examining parameter stability, robust standard errors, and consistent estimators under heteroscedasticity.Implementing the TVP method, the results show that the parameters are not stable and that there is a bidirectional causality relationship between import growth and economic growth, and between export growth and economic growth. According to the results of the REW method, there are causality relationships arising from economic growth with both export growth and import growth between 2011–2016. There are also causality relationships from export growth and import growth to economic growth between 2006–2008. Additionally, there are bidirectional causality relationships between import growth and economic growth between 2007–2008 and in 2016. Therefore, even if there is a causal relationship between the variables in different periods, it sharply prevents the rejection of the null hypothesis that there is no causality. These results provide evidence that the causal relationship may change over time.Consequently, according to the results of the time-varying causality relationship, the relationship between foreign trade and economic growth in Turkey varies intensively between 2006–2008 and 2011–2016. Thus, both the global economic crisis and the European debt crisis have affected Turkey. The estimated parameters while examining the causality relationship did not show stability.&nbsp;

Turkish society is one of the few in the world that has traditionally used gold as a form of saving and investment. In general, Turkish people acquire gold for marriage, to buy a house, and for the future saving for themselves or their offspring. This gold is typically stored in their houses. “Gold under the Pillow” is gold that is not in any financial system but is held in various locations. In Turkey, there is approximately 3–5 tons of gold that is not involved in the financial system and is so-called “under the pillow.” The gold in question is worth between 200–300 billion dollars. The coronavirus disease-19 pandemic has hampered economies world-wide, including Turkey. The Turkish economy will recover if the gold financial system, which is hidden beneath the aforementioned pillow, is incorporated.Concurrent with the advancements in the banking system, the integration of various investment instruments into the banking system has also improved. In this regard, a similar situation was observed with gold, which is one of the most important investment and saving tools. Although the relationship between gold and the bank has a long history, the gold banking system has become more comprehensive as a result of technological and systematic advancements in the banking system. Therefore, the idea of banks to assess individual gold saving has continued to gain interest. However, despite this interest in banks, an individual’s interest in gold banking is not at the desired level.In this study, the individual’s awareness regarding gold banking and their choice to utilize the gold banking system were investigated. The study aims to discover the factors that influence the decisions of individuals on whether or not to utilize the gold banking system. Thus, individual data within the Istanbul area were obtained via questionnaires and were examined. The findings highlight the fact that most participants have yet to use the gold banking system. To analyze the reasons for this situation, factor analysis was used and the main factors were identified. Next, considering the asymmetrical distribution in the use of gold banking, the Gompit Model, one of the qualitative preference models, was calculated and the main factors&nbsp;that influence the decisions of individuals about gold banking were discovered. According to the results, the primary reason why individuals do not utilize gold banking is a lack of knowledge about the system. Most participants claimed that they might utilize the system to get educated about the gold banking system. Another critical aspect is the distrust in banks and the reliability of keeping gold under the pillow. It was noted that individuals who regard gold as an investment or security were more likely to utilize the gold banking system. Another promising point is that the systems returns are higher. It has been determined that individuals may be more willing to use the system if gold banking provides more profits. Furthermore, it was discovered that individuals with larger savings are more inclined to use the gold banking system.Based on the result, it can be concluded that the essential policies to be implemented to incorporate the “under the pillow” gold in the system should focus on better educating individuals and developing their confidence in banks. Individuals who wish to use gold as a means of investment and savings will include their gold in the system, and the gold “under the pillow” will be included into the economy, if they have an adequate understanding of gold banking and do not have a negative attitude toward banks.&nbsp;

In contemporary economic inquiry and public policy, the concept of innovation has gained more significance compared with previous years. One reason for this is countries’ efforts to leverage the phenomenon of globalization in their interests. Countries can integrate into the global economy and increase gross national income through innovation that will turn globalization to their favor. Innovation is of substantial significance for businesses’ growth and longevity. It is one of the primary factors required for business survival and sustained development in the global economy. Because of globalization, companies must be more creative and exploratory in the face of increasing competition and scientific and technological development. Companies’ survival now depends on their level of innovation and technological development. Innovation activities have a crucial impact on countries’ economic growth and development. It is at the heart of economic growth and development and has strategic importance for policymakers and business leaders to increase national global competitiveness, welfare, and quality of life.Reviewing previous empirical studies on innovation and the factors affecting innovation, a limited number of studies have used multivariate models. Although many studies examine the relationship between innovation and various variables, multivariate linear regression models are predominantly used in these limited studies.This study aims to investigate the factors affecting innovation. A panel VAR model was estimated using a panel dataset for selected OECD countries for the period 1981–2019. The model was estimated using the sample countries’ annual data on the number of domestic patents as the dependent variable and independent variables of GDP, trade openness, foreign direct investment, R&amp;D, and education expenditure. Based on the predicted panel VAR model, a panel Granger causality test and variance decomposition analysis were performed, and impulse-response functions were interpreted.The findings of the VAR analyses were threefold: i) The Granger causality test between a causal relationship from the variables of trade openness, foreign direct investment, and R&amp;D and the number of patents. ii) Impulse-response functions indicated that the variables of GDP, trade openness, and R&amp;D expenditure positively affect the number of patents in the short run. iii) A variance decomposition analysis demonstrated that the most crucial variable affecting the number of patents is GDP.According to these findings, GDP, trade openness, foreign direct investment, and R&amp;D expenditure are the primary factors affecting innovation.Considering the results, an increased demand for the innovation process and innovative applications positively affect innovation. Because increased income is measured using GDP, rising foreign trade volume and foreign direct investment&nbsp;inflow are the most significant variables for the increasing innovation demand. The positive effect of increased GDP on innovation is also quite significant in terms of facilitating innovation and R&amp;D financing and support and expanding purchasing power. R&amp;D expenditure was revealed to be the primary mechanism of countries’ innovation level.&nbsp;

This study explores the relationship between HT concentration and income and the validity of the diversification curve. The validity of the resource curse hypothesis for the HT sector is tested. The effect of the country scale and trade volume on concentration in the HT sector is also examined.This research uses empirical methods to analyze the relationship between HT-export concentration and income. Concentration coefficients in the HT sector were calculated using three different indices: the Herfindahl-Hirschman Index (HHI), the Gini-Hirschman Index (GHI), and Entropy Index (EI). These indices, which are used to measure the concentration of variables in various subjects in different disciplines, are generally used in the field of economics to measure firm concentration in the markets and geographical concentration in foreign trade. An increase in index values indicates diversification, and a decrease indicates concentration. In the entropy index, the increase indicates diversification, unlike other indices.These data were used in regression analysis as a dependent variable at the next stage. Variables used in the study were obtained from the World Integrated Trade Solutions (WITS), World Bank (WB), OECD, and United Nations Conference on Trade and Development (UNCTAD) databases in a sample covering the period 1988- 2017 in 49 countries. The countries included in the sample were predominantly OECD economies. It was found that linear SEK assumptions could not be met in the tests of autocorrelation, heteroskedasticity, and cross-section dependence on panel regression residuals. In consideration of these problems, regression with DriscollKraay (1998) standard errors gives robust results. The F values obtained from the estimates show that the models are generally significant. The stationary regression residuals eliminate the possibility of spurious regression and indicates that the series are cointegrated. The variance inflation factor was calculated to be more diminutive than the critical threshold value (Mean VIF = 2.14 &lt; 10), showing no multicollinearity between variables. Because the variables are used in logarithmic form, the estimated coefficients can be interpreted directly as elasticity.The findings obtained by panel data econometrics in a sample from 1988 to 2017 in 49 countries show that the U-shaped relationship put forward for general export does not apply to HT export. There is no concentration or diversification curve for HT exports. However, the driver of HT-export diversification has been found to be income level. As income levels increase, countries can diversify HT products. A linear and negative relationship was found between export concentrations and income in the HT sector. When the income increases by 1%, the HT-export concentration decreases by approximately 0.14 units compared to the HHI index. In other words, diversity increases.Natural resource wealth is not a hindrance to HT-export diversification, but rather contributes to diversification. This finding suggests that resource abundance does not exclude technological progress and knowledge economy activities. As control variables, country scale and trade volume indicators contribute positively to HT concentration. A 1% increase in the population increases HT-export concentration to 0.47 units according to the HHI index; the increase in openness increases by 0.25 units. In addition, when the interval estimates are examined together with the point estimates, the coefficient signs do not change. This result contradicts the literature put forward for general export. In the rankings of all indices, South Africa, Italy, the United States, Austria, and Germany appear as the countries with the lowest degrees of concentration.The possibilities and limitations of this study fall within the framework of panel data econometrics assumptions. However, the accuracy of the data obtained from the databases constitutes another constraint. The findings are at the country level and do not contain information on sectors and regions.Policy makers aiming at product diversification in the HT industry must first design policies that target and promote income levels. To achieve income growth, the macroeconomic environment such as investment and savings levels, institutional and legal structure, as well as primary production factors (human and physical capital, R&amp;D stock) put forward by growth models must be convenient. Where the resource curse hypothesis is valid, where knowledge economies and technology-intensive activities are restricted and production structure and trade are concentrated in primary goods (natural resources), countries should focus on institutional structure reforms necessary to overcome the vicious cycle. Good management of natural resources and corporate structure will increase the diversification in HT exports.The relationship between HT-export concentration and income has not yet been extensively analyzed according to the level of technology. The present study aims to remark on this point. This aspect makes it will be a pioneering study in the literature. Also, this is the initial study in the literature that tests the validity of the resource curse hypothesis for the HT sector.&nbsp;

The scientific theory of human-induced climate change is well established and goes back almost two centuries. Solar energy drives the earth’s climate, and the atmosphere is the principal component of the system that maintains the earth’s radiative balance. As a result of human activities such as fossil fuel-based energy consumption and deforestation, heat-intercepting greenhouse gases are emitted into the atmosphere. Capable of absorbing thermal radiation, these greenhouse gases accumulate in the atmosphere and affect the radiative balance of the earth. In the period of just two hundred and fifty years after 1750, atmospheric concentrations of the most important greenhouse gases, namely carbon dioxide, methane and nitrous oxide have risen by 40%, 150%, and 20%, respectively. As a consequence of the higher quantity of greenhouse gases in the atmosphere, global average temperatures have risen by 1.1 °C over the same period. In addition to increasing global temperatures, it is easy to find empirical evidence about anthropogenic climate change in the climate system. Ocean acidification, the increasing heat of the oceans, rise in sea levels, destruction of coral reefs, melting ice sheets, and retreating glaciers are listed among the most critical impacts of climate change. The scientific consensus on climate change can be found in the climate science literature. According to the most quoted evidence of the consensus among scientists, 97% of the scientific papers published in scientific journals accept that climate change is occurring, and the main cause is human activity. The Intergovernmental Panel on Climate Change, which is the leading scientific authority on climate change, states, in its 5th climate assessment report (2013), that the “Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased…It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century…”The picture emerging in the scientific field shows that the sustainable solution to climate change lies primarily in reducing human-induced greenhouse gas emissions. The key document signed in the international arena on climate change is the United Nations Framework Convention on Climate Change (UNFCCC), which was signed in 1992. In Article 2 of the Convention, it is stated that the ultimate goal of the UNFCCC “is to fix the greenhouse gas concentrations in the atmosphere at a level that will prevent a dangerous human intervention to the climate system.” Conversely, the distinction between developed and developing countries, especially in terms of responsibilities regarding greenhouse gas reduction has become an important problem to be overcome in international negotiations. For example, in Article 3 of the UNFCCC, which lists the basic principles to be followed to achieve the ultimate goal, concepts such as equity, development, precaution, and sustainability are highlighted. According to these principles, “the climate system should be protected for the benefit of present and future generations and by the principle of equity.” As a requirement of the principle of equity, the responsibilities of developed and developing countries should be common but following differentiated responsibilities and respective abilities.Within the Kyoto Protocol, which was negotiated within the scope of the UNFCCC and signed in 1998 and whose implementation period started in 2005, developed countries committed to cutting their average greenhouse gas emissions by 5%. The distinction between developed and developing countries in terms of emission reduction commitments has been one of the most prominent aspects of the Kyoto Protocol. Another internationally important document, signed in 2015, is the Paris Agreement. Unlike the Kyoto Protocol, in the Paris Agreement, the main target is to hold the increase in average temperatures in the twenty-first century to well below 2 °C compared to the pre-industrial period. In addition to the 2 °C target, it is decided that efforts should be pursued to limit the temperature increase to 1.5 °C above preindustrial levels. Unlike the Kyoto Protocol in which countries aim to participate in an emission reduction target determined at the international level, the parties in the Paris Agreement set a target according to themselves. Although it is presented as a single agreement, the Paris Agreement consists of different national commitments prepared and announced by the parties, in line with their own conditions. Although international participation against climate change has been achieved in the agreement, it is seen that the de facto distinction between developed and developing countries in the UNFCCC is maintained.The fact that there are developed and developing countries among the G20 countries, including Turkey, makes it possible to analyze the political divergence in the fight against climate change since the UNFCCC. However, the fact that the G20 countries constitute 63% of the world’s population, 80% of the national income, 78% of the energy supply, and 81% of the fossil-fuel based carbon dioxide emissions as of 2017 helps to interpret the results of the analysis in terms of the world. The cluster analysis based on per capita income and carbon dioxide emissions show that the gap between developed and developing countries did not close in the 1990-2017 period. The increase in the total emissions of countries such as China and India is remarkable. However, within the G20, developed countries’ per capita emissions are still relatively high compared to developing countries. As a global environmental problem, human-induced climate change requires the participation of all countries. However, demographic, economic, and technological differences between countries indicate that achieving global cooperation is not as easy as desired. The sustainable solution or management of climate change necessitates reducing these differences between countries. At this point, the aim should not only be to put pressure on developing countries to reduce their greenhouse gas emissions but also to build a structure that helps developing countries to gain the institutional, economic, and technological capability and capacity they need in the fight against climate change.&nbsp;

An index can be defined in statistical research as a measure of change in a representative sample of individual data points, or as a composite measure that combines many indicators. Indices, sometimes known as composite indicators, are used to summarize and categorize individual data. In this manner, the researcher can evaluate the subject under investigation using criteria, such as good to poor, strong to weak, remote close, and make conclusions regarding the study subject. In this research, a new index ranking calculation is proposed using economic freedom data. In the proposed method, a hybrid approach was presented, in which spatial econometrics, fuzzy C-means from fuzzy clustering analysis methods, and COPRAS methods from multicriteria decision-making (MCDM) methods are used together. The purpose of this strategy is to calculate a sorting method with spatial connection coefficients as input, fuzzy C-means, and data as the output of the process and COPRAS method.The subject of economic freedom is a concept that covers the entire concepts of freedom of choice, exchange, and competition, and protection of property. In other words, economic independence may be defined as an individual managing their property and labor without regard for the constraints imposed by the state or other groups. It is the most basic right of individuals to engage in economic activities using their rights over their property within legal frameworks and gains as a result of these activities in the areas they desire. Governments should also protect people’s property rights and enable free movement of labor, capital, products, and services that enable activities like production, consumption, and investment. There are independent organizations, such as the Fraser Institute, The Heritage Foundation, the Cato Institute, and Freedom House that work on measuring economic freedom around the world. With the studies they issue each year, these organizations examine the state of countries in terms of economic freedom. Governments and business companies may monitor the changes in the nations of interest for each year and accordingly launch or amend their investments based on these reports released under various data categories.Spatial econometrics is a subscience of econometrics that focuses on combining spatial influence with econometric methods. This discipline of study is primarily concerned with spatial effects, which show the pattern of spatial decoupling. The interaction between the geographic domain, which is described in terms of spaces, horizontal cross section dependency, which is a subset of spatial dependence, and cross sectional heterogeneity, which is a subset of spatial heterogeneity, may result in. The dependency structure can be related to distance and location, and this structure can be seen in a geographical area, as well as in an economic or social network area.&nbsp;Clustering analysis is one of the most widely used methods in classification studies. Clustering analysis is a method for classifying the units analyzed in research by grouping them according to their resemblance, identifying the common qualities of the units, and making broad assumptions about these classes. The purpose here is to categorize ungrouped data based on similarities and assist the researcher in obtaining relevant and valuable summary information. Fuzzy clustering is recommended as an appropriate method if the sets are not fully and precisely separated from each other or there are suspicious situations in which set some observations are elements.Fuzzy sets, collections of observations in which the membership record is specified between 0 and 1, decide each observation function. Observations that have a high degree of membership in the same cluster are quite comparable. Each observation does not have to be included in only one set in fuzzy clustering. In this method, observations belong to clusters with certain degrees of membership, and information about the observations’ membership to other clusters is obtained.MCDM methods are used when it is necessary to assess a large number of alternatives under a large number of criteria.Individuals, corporations, and organizations encounter multidimensional choice challenges in their daily lives. Managers frequently make judgments when several factors and competing goals (criteria) must be met. MCDM techniques consist of approaches and methods that try to reach a possible “best/appropriate” solution that meets multiple conflicting criteria. Decision-makers can make scientific and more successful decisions using MCDM techniques to overcome such problems.A hybrid technique integrating geographical econometrics, fuzzy clustering analysis, and MCDM was developed in this work for a unified measure ranking of the quality of political–economic institutions in various jurisdictions, such as economic liberties. The proposed method was calculated on the Heritage Foundation economic freedom data and compared for the years 2019, 2020, and 2021. The suggested method’s rankings for three separate eras were calculated as 88.6%, 91.7%, and 92.7%, with correlation values with the original Heritage Foundation rankings. These high correlation values were also found to be significant at 1%. The high correlation values of the findings acquired in the index sorting research developed to suggest that the proposed hybrid approach may then be employed in additional index computations, according to the results.&nbsp;

The natural resource factor is one of the most important sources of economic growth. As the effects of environmental problems, particularly global warming, worsen, the environmental damage, the effects on future generations, and the methods used in production activities have begun to be discussed by countries attempting to meet their economic targets. The increase in mass production and urbanization has increased the energy required to sustain economic activity, which has been met by the use of fossil fuels. Such fossil fuel use increases the amount of greenhouse gases released into the atmosphere, with the energy sector being the most significant contributor. Because of the global nature of the problem, some steps have been taken to reduce emissions and prevent environmental pollution for sustainable development. In this context, international agreements to reduce emissions, such as the Kyoto Protocol and the Paris Agreement, have been signed, and environmental policies have been developed. The emergence of environmental problems has increased the interest of researchers in this field. Moreover, many studies have examined the relationship between environmental factors and economic growth and made policy recommendations for sustainable development. The environmental Kuznets Curve (EKC) hypothesis has been used to analyze the relationship between emissions and growth in the majority of the related literature. However, Gill et al. (2018) claimed that the results of EKC analysis were extremely sensitive to the period chosen and the model specification. When new variables are added to the model, the results of the EKC hypothesis may change, causing different turning points in the curve. Müller-Fürstenberger and Wagner (2007) and Aslanidis (2009) both criticized the EKC hypothesis. In light of the EKC hypothesis reviews, the present study analyzed the relationship between the variables from an asymmetric perspective using the variables’ cumulative positive and negative shocks.The current study examined the short- and long-run asymmetric causal relationship between carbon emissions and economic growth in Turkey using annual data from 1960 to 2018. In this context, Hatemi-J (2012) examined short-run asymmetric causality between variables, whereas Granger and Yoon (2002) examined long-run asymmetric relationships using hidden cointegration. The result of the short-run analysis reveals that decreases in emissions reduce economic growth in the short run. Moreover, the positive developments in economic growth increase emissions in the long run. Furthermore, positive movements in economic growth leads to an increase in emissions in the long run. Another significant finding is that the negative growth development increases the increase in emissions in long run. Moreover, asymmetric causality exists from negative growth shocks to positive emissions shocks in the long run.Meanwhile, examining crouching error correction estimation results, we determined that positive and negative shocks in economic growth are permanent components, whereas positive and negative shocks in emissions are transitory. In other words, positive or negative developments (positive or negative shocks) in growth affect both itself and emissions, thus determining long-run relationship dynamics between the variables. Meanwhile, positive or negative shocks in emissions affect only themselves and are impermanent in the long run.Positive and/or negative developments in economic growth constantly increase emissions. Therefore, to ensure sustainable development and reduce emissions emitted into the atmosphere, stakeholders must increase the use of renewable energy resources, expand the use of clean technology, and pave the way for environmental policies to be developed.&nbsp;

In this globalized world, supply and demand are on the rise, where access to international markets is easier than ever because of the advances in technology. With easier access to markets, countries got into fierce competition involving their companies operating on a global scale. This phenomenon puts companies and thus countries into a competition with no limits. Examining the countries that gained independence after the dissolution of the Soviet Union in 1990 and were described as Transition Economies in the 1994 United Nations Framework Convention on Climate Change will be helpful in determining if they are capable of competing with other countries while also providing them with necessary policy recommendations. Transition economies, particularly those on the European continent, have the potential to compete with European Union (EU) countries in foreign trade owing to their relatively more developed position in terms of economy and their geographical proximity to EU countries.This study analyzed whether the foreign trade-driven competitive power of the 13 transition economies (i.e., Albania, Bulgaria, Czech Republic, Estonia, Croatia, Latvia, Lithuania, Hungary, Macedonia, Poland, Romania, Slovenia, and Slovakia) converges toward that of the 14 main European Union countries (EU14) for the period of 1993:M01–2021:M08. These countries are either members or candidates for the EU, and their data are entirely accessible. The study used the Fourier panel unit root test with sharp and smooth breaks developed by Bahmani-Oskooee et al. (2014).&nbsp;Foreign trade-driven competitive power can be measured using different indicators. In this study, it was measured based on the real effective exchange rate for relative prices. As part of the analysis, first, the presence of a cross-sectional dependence among transition economies was examined using the tests developed by Breusch and Pagan (1980) LM, Pesaran (2004) LMS, and Baltagi, Feng and Kao (2012) LMBC. A cross-sectional dependence was observed among these countries. Then, the panel unit root test was applied, which was developed by Bahmani-Oskooee et al. (2014), by considering the cross-sectional dependence among countries. According to individual analyses, transition economies, except for Croatia, were found to be in a closer position to EU14 countries in terms of foreign trade-driven competitive power. Considering the presence of sharp and smooth structural breaks in series, other analyses on the overall panel revealed that the 13 transition economies, included in the panel, converge toward EU14 countries in terms of foreign trade-driven competitive power. Moreover, the testing method was able to successfully determine the sharp and smooth structural breaks in these countries. The findings of this study show that transition economies that joined the EU at a later stage or are candidates for the EU have successfully carried out the EU harmonization process. Conversely, the EU is providing financial and technical support to these now-member or candidate countries to increase their production level and foreign trade volume while simultaneously enhancing their foreign trade-driven competitive power.&nbsp;

Nowadays, there are many investment tools in the financial markets to assess the savings of individual investors. The diversity of investment instruments in the market makes it difficult for investors to make decisions about evaluating savings. Furthermore, developments and uncertainties in the economy affect the individual investor’s investment decision. In the economy, individuals use part of their income for consumption expenditures and savings. Individuals who make savings are evaluated byvarious investment instruments in order to make a profit. In this process, the main objective of investors is to obtain the highest return with minimum risk. Investors evaluate their savings in investment instruments with a certain expectation of return. The existence of many investment instruments in the economy reveals the issue of which investment instrument the investor should use. A balanced distribution of investor accumulation in multiple investment instruments instead of a single investment instrument will provide protection against fluctuations in the markets. Throughout the history of finance, studies have been conducted on how markets affect individual investment preferences. Investors follow the political, economic and social situations in the markets to make the right investment decision. There are many investment tools for transferring the idle resources to the financial system. Financial investment instruments provide the opportunity for individuals who make savings to protect their capital and earn money. For this reason, financial decisions are important in the efficient functioning of the market. All future financial decisions include uncertainty. The uncertainty of the future makes investors’ decision difficult. The financial decisions of investors who wish to use their savings in various investment instruments are important in the efficient management of funds in the economy. Decisions have a significant impact on financial markets. Monetary loss or profit as a result of the investment makes it difficult for investors to make decisions. Individual investors aim to achieve the highest risk with the lowest risk in financial investment decisions. If the risk of a financial investment instrument is high, the expectation of high return on this investment instrument increases. Traditional finance theories are based on the principle that individuals make decisions by acting rationally. Individual investors make a rational choice of financial investment instruments in their investment decisions and strive for maximum return on their savings. Since investors are rational, they analyze decisions in financial investment instruments rationally. However, in this process, the investor encounters many factors affecting the investment decision in the market. The decisions taken affect the outcome of the investment either positively or negatively. Therefore, the evaluation of the criteria affecting the investment decision has been included in many academic researches.&nbsp;In this study, the importance of the criteria affecting the investment decisions of the investors trading in financial markets is analyzed. The aim of this study is to compare the criteria that the financial investment decision makers take into consideration in the decision-making process. The criteria included in the study; Global Markets, Domestic Financial Indicators, Investment Instrument Characteristics and Analysis Techniques Used. The aim of this study is to reveal the economic, social, investment instrument characteristics and analysis techniques that are useful in the process of evaluating the savings of individual investors in financial investment instruments. The purpose of this study is to provide a new perspective by evaluating the relationships between the criteria affecting investment decision with the Fuzzy DEMATEL method. In addition to the support from the literature, my financial work experience contributed to my study in the process of determining the criteria included in the study. In this study, the Fuzzy DEMATEL method was used and the opinions of 10 experts responsible for financial decisions were taken. As a result of the findings obtained from the opinions of the experts based on the criteria, the most important criterion among the criteria was revealed to be Technical analysis. Investors pay attention to past price movements of investment instruments in decision-making. The second criterion that was given importance among the criteria was Global markets. After the financial globalization, all the information related to the economic and political situation of countries affect the values of the investment instruments in the market.

This study evaluates the relations between economic performance, democracy index and economic freedoms, which are widely discussed in economic theory. The aim of this study is to investigate the direct and indirect effects of democracy index and economic freedoms on economic performance. The study was conducted with the data of 45 European countries for 2017. Data from countries with insufficient information was excluded from the analysis. Data on the economic freedom variable The Heritage Foundation, from the link: https://www.heritage.org/index/ explore?view=by-region-country year &amp; u = 636967067347971774), also contains data on the democracy index variable. The democracy index report published by the Economist Intelligence Unit (The EIU) can be found at the link: https://pages.eiu. com/rs/753-RIQ 438 / images / Democracy_Index_2017.pdf). Data for the economic performance variable were obtained from the International Monetary Fund (IMF) and the World Bank (World Bank) database. The concept of freedom can encompass many different definitions of the idea of economic freedom. Some of these definitions are as follows: Economic freedom consists of a combination of property rights and the protection of individuals, the right to make individual choices and the freedom to compete (Gwartney ve Lawson, 2003, p.406). The concept of economic freedom therefore can be understood to mean that people voluntarily engage in consumption and investment activities at any time without the control and restrictions of the state, that their rights are under state protection and that they participate in the labor force (Şenalp, 2018, p.319). When democracy is defined as a political system, it is a regime in which all adults have the right to vote, where candidates in the election can freely compete, and through periodic elections, decision makers come to power with strong authority (Huntington, 1984, p.195). Democracy also provides freedom and the possibility of self-determination (Schwartz, 1993, p.552). A two-stage approach was used to determine the consistency of the data used in the study with the research hypotheses (Anderson and Gerbing, 1988). In the first step,&nbsp;the measurement model was tested to determine whether the observed variables in the model accurately measured the latent variables to which they belong. This stage of the analysis is considered as Confirmatory Factor Analysis. If the indicator variables that make latent variables measurable do not accurately measure the constructed structure, the next step, the structural model, will not need to be tested. For this reason, the measurement model must meet the requirements for compliance. The second stage includes the testing of the structural model (Huchting, Lac and Labrie, 2008, p.543). When the model was evaluated according to the obtained t-values, there was a direct relationship between economic freedom and democracy index, and between democracy index and economic performance, while no direct relationship was found between economic freedom and economic performance. This suggests that the index of democracy may be a mediating variable. In order to evaluate the mediation effect, a significant relationship was found between economic freedom and economic performance. When the index of democracy is included in the model, the value of the path coefficient between these two variables decreases and the path becomes meaningless. In this case, it can be said that the index of democracy fully mediates the relationship between economic freedom and economic performance. In other words, the relationship between economic freedom and economic performance is indirectly realized through the democracy index. The fact that there is a direct relationship between economic freedom and democracy index and democracy index and economic performance supports the mediating effect (Judd and Kenny, 1981, pp. 605-606; Baron and Kenny, 1986, p.1176-1177). This study shows that economic performance and economic freedom, which are the determinants of the institutional structure for European countries, can be increased with economic performance and economic freedoms in order to improve democracy. For sustainable economic performance, countries should strengthen and add importance to their institutional structures. Countries aiming to increase their economic performance should set policies to increase their democracies and economic freedoms. Since the findings obtained belong to a certain group of countries, they cannot be generalized for all countries of the world. In future studies, analyses can be made for different country groups and time periods. The results obtained by using different analysis programs and different estimation methods can then be compared. The sub-components of economic freedom affect the environment and functioning of the market and contribute to the development of democracy, with the effect it has on entrepreneurship. Furthermore, individual commercial activities positively affect economic performance.

Purchasing power parity (PPP), which is one of the subjects of interest in international finance and economy, is defined as a rate of change that equalizes the purchasing power of different currencies by eliminating price level differences between countries (TURKSTAT, 2008). In other words, the theory of purchasing power parity states that the nominal exchange rate between the two currencies is determined by the purchasing power of each country’s currency. This means that the exchange rate between the two countries must be equal to a fixed level of goods and services basket price of the two currencies. While economists generally doubt the validity of PPP in the short term, they agree that it is necessary to investigate whether PPP is valid in the long term because price differences between countries are not sustainable in the long term (Acaravcı and Öztürk, 2010). Chortareas and Kapetanios (2009) evaluated the importance of purchasing power parity in terms of both traditional and new approaches to open economy macroeconomics for policy purposes. According to the traditional approach, the validity of PPP is valuable information for policy-makers who want to evaluate the effects of devaluation since the effects of devaluation under PPP on competitiveness will be eliminated in the long term. In open economies with new approaches, PPP is a necessary condition for equalizing market integrity and marginal utility. Empirical studies use cointegration tests, variance ratio tests, and quantitative regressions for nominal exchange rates and prices, and unit root tests for real exchange rates, to assess the validity of PPP. (Chortareas and Kapetanios, 2009; 391). The estimation of PPP exchange rates is very important for practical purposes. These objectives are; (i) determining the degree of deviation from the nominal exchange rate, ie determining whether the exchange rate is low or not. (ii) making appropriate policy decisions; (iii) adjusting currency parities; (iv) an international comparison of national income levels; and (v) a comparison between domestic price and foreign price (Sarno and Taylor, 2002). Whether PPP is valid or not should be examined. Where PPP is not valid, PPP cannot be used as a criterion for international income level comparison and estimation of real exchange rates, and where applicable, it can be used as a criterion for the level of development comparisons and the reliability of all economic decisions (Güriş et al. 2016). . In this study, the validity of purchasing power parity was examined using Fourier unit root tests for Turkey for the period 1992:01-2018:12. In order to make a comparison, two different recently developed unit root tests were used in the study. The study is expected to contribute to the current literature in terms of the method used. The studies for Turkey is as follows; Gurbuz and Hasgur (1997), Telatar and Kazdagli (1998), Erlat (2003), Yazgan (2003), Alba and Park (2005), Aslan and Kanbur (2007), Ozdemir (2008), Kalyoncu (2009), Lightning and Lightning (2012), Sener et al. (2015), Güriş et al. (2016), Rock and Steel (2018). In cases where series do not have a linear structure, nonlinear unit root tests give more powerful results than linear unit root tests. In the literature, there are unit root tests examining stationarity structures of nonlinear series. In this study, Güris (2018) and Ranjbar et al. (2018) non-linear Fourier unit root tests were used. Firstly, the linearity of the calculated real exchange rate series was examined and it was found that it does not have a linear structure. In the second part of the empirical analysis, the stationarity of the series was examined with the help of Fourier unit root tests. The obtained results indicate that Turkey has a stationary structure in the real exchange rate series. Accordingly, it is seen that the PPP hypothesis is valid for Turkey. In other words, the analyzed period, the real exchange rate being stationary and Turkey coming to the real exchange rate shocks are temporary. The validity of PPP means that the prices of goods expressed in the same currency are the same anywhere in the world. Therefore, PPP is expected to play an active role in the monetary policy decision for Turkey.

Only those manuscripts approved by every individual author and that were not published before in or sent to another journal, are accepted for evaluation.Changing the name of an author (omission, addition or order) in papers submitted to the Journal requires written permission of all declared authors.Plagiarism, duplication, fraud authorship/denied authorship, research/data fabrication, salami slicing/salami publication, breaching of copyrights, prevailing conflict of interest are unethical behaviors. All manuscripts not in accordance with the accepted ethical standards will be removed from the publication. This also contains any possible malpractice discovered after the publication. Plagiarism Submitted manuscripts that pass preliminary control are scanned for plagiarism using iThenticate software. If plagiarism/self-plagiarism will be found authors will be informed. Editors may resubmit manuscript for similarity check at any peer-review or production stage if required. High similarity scores may lead to rejection of a manuscript before and even after acceptance. Depending on the type of article and the percentage of similarity score taken from each article, the overall similarity score is generally expected to be less than 15 or 20%. Double Blind Peer-Review After plagiarism check, the eligible ones are evaluated by the editors-in-chief for their originality, methodology, the importance of the subject covered and compliance with the journal scope. The editor provides a fair double-blind peer review of the submitted articles and hands over the papers matching the formal rules to at least two national/international referees for evaluation and gives green light for publication upon modification by the authors in accordance with the referees’ claims.

Although references to review articles can be an efficient way to guide readers to a body of literature, review articles do not always reflect original work accurately. Readers should therefore be provided with direct references to original research sources whenever possible. On the other hand, extensive lists of references to original work on a topic can use excessive space on the printed page. Small numbers of references to key original papers often serve as well as more exhaustive lists, particularly since references can now be added to the electronic version of published papers, and since electronic literature searching allows readers to retrieve published literature efficiently. Papers accepted but not yet included in the issue are published online in the Early View section and they should be cited as “advance online publication”. Citing a “personal communication” should be avoided unless it provides essential information not available from a public source, in which case the name of the person and date of communication should be cited in parentheses in the text. For scientific articles, written permission and confirmation of accuracy from the source of a personal communication must be obtained.Reference Style and FormatEKOIST: Econometrics and Statistics complies with APA (American Psychological Association) style 6th Edition for referencing and quoting.
