1995-2011 döneminde Avrasya ekonomilerine yapılan doğrudan yabancı yatırımların (DYY) dünya trendi ile karşılaştırılması
(2013) Tuzla, Hayri; Teker, Suat
Küreselleşen ve gün geçtikçe sınırların azaldığı dünyamızda doğrudan yabancı sermaye yatırımları, başta ekonomik büyüme ve işsizlik olmak üzere, ülkelerin birçok farklı makro verisini etkilemektedir. Mevcut araştırmalar, doğrudan yabancı sermaye yatırımlarının ekonomik büyümeyi etkilemesi yönünde güçlü bir nedensellik ilişkisi olduğunu desteklemektedir. Ekonomik büyümenin doğrudan yabancı sermaye yatırımlarınıetkilemesi yönünde ise, daha zayıf bir pozitif nedensellik ilişkisi tespit edilmiştir. Böylece, ekonomik büyümenin bir sonucu olarak, işsizlik oranlarında bir azalma beklenebilir. Bu çalışma, yedi Avrasya ülkesinin (Azerbaycan, Kazakistan, Kırgızistan, Tacikistan, Türkiye, Türkmenistan ve Özbekistan) 1995 yılından 2011'e kadar çekmiş olduğu doğrudan yabancı sermaye yatırımları trendini, hem bu ülkeler arasında hem de dünya trendi ile karşılaştırmaktadır.

Backcasting Bitcoin volatility: ARCH and GARCH approaches
(Suat Teker, 2024-12-31) Teker, Dilek; Teker, Suat; Demirel Gümüştepe, Esin
Purpose- The primary purpose of this study is to model Bitcoin price volatility and forecast its future price returns using advanced econometric models such as ARCH and GARCH. The study aims to enhance risk management strategies and support informed investment decisions by addressing the time-varying nature of Bitcoin’s volatility. The research explores the persistence of volatility shocks and the clustering of price movements to provide insights into market dynamics. Methodology- This research examines daily Bitcoin closing prices over the period from January 2020 to October 2024. The data was preprocessed to ensure reliability, including applying logarithmic transformations to standardize the data and eliminate trends. Stationarity tests, such as the Augmented Dickey-Fuller (ADF), Phillips-Perron (PP), and KPSS tests, were conducted to confirm the series' stationarity. The ARCH-LM test was utilized to detect volatility clustering which is essential for validating the use of ARCH and GARCH models. Following this, ARIMA models were employed to define mean equations and GARCH models were used to estimate conditional variance and capture volatility dynamics. The dataset was split into training and validation subsets with data from July to October 2024 reserved for validation. Findings- The findings demonstrate that Bitcoin’s price movements exhibit significant volatility clustering and persistence of shocks which are key characteristics effectively captured by ARCH and GARCH models. These models provide valuable insights into the volatility patterns of Bitcoin, supporting their application in cryptocurrency analysis. Despite their robustness, the models face limitations in precise return forecasting during highly volatile periods, suggesting the need for further refinement or integration with advanced approaches. Conclusion- The research concludes that ARCH and GARCH models are effective tools for understanding and forecasting Bitcoin’s volatility. The study underscores the importance of acknowledging volatility persistence and clustering effects when analyzing cryptocurrency price behavior. However, it also highlights areas for improvement in econometric modelling by including the exploration of hybrid models and the integration of macroeconomic factors to enhance forecasting accuracy.

(PressAcademia, 2020-07-30) Yüksel, Mihriban; Teker, Suat
Amaç- Türkiye’de 5018 sayılı Kamu Mali Yönetimi ve Kontrol Kanununun (KMYKK) yürürlüğe girmesiyle eski kanunun aksine birçok yeni düzenleme getirilmiştir. Uluslararası Standartlar ve Avrupa Birliği kontrol mekanizmasına uygun bir iç kontrol sistemi oluşturulmaya başlanmıştır. Bu araştırma, belediyelerde meydana gelebilecek usulsüzlük ve yolsuzluk gibi olumsuz olayları engellemek ve finansal ve finansal olmayan her türlü işlemin kontrolünü sağlayarak iç kontrol sisteminin stratejik yönetim üzerindeki etkisini ortaya koymak ama cıyla yapılmıştır. Yöntem- İstanbulda yer alan 21 ilçe belediyesine ait iç kontrol eylem planları ve stratejik yönetimin temel unsuru olan stratejik planları mevzuat hükümleri ve başlıca yönetişim ilkeleri olan hesap verebilirlik, katılımcılık, açıklık ve etkinlik kriterlerine uygunluğu incelenmiştir. Verilerin analizinde dörtlü likert ölçek kullanılmış ve yorumlayıcı bir yöntemle değerlendirmeler yapılmıştır. Bulgular- Araştırma kapsamında iç kontrolün etkinliğine yönelik gerekli eylemlerin belirlendiği ancak kurumsal risk çalışmalarının yetersiz olduğu, iç kontrolün izleme bileşenine daha çok önem verilmesi gerektiği dolayısıyla stratejik yönetime etkisinin yüksek önemde olduğu tespit edilmiştir. Sonuç- Belediyelerde iç kontrol sisteminin, bir yönetim modeli olarak üst yönetici tarafından kurgulanması ve iç kontrolün 5 bileşenin koordineli bir şekilde yürütülmesi gerekmektedir. Ayrıca stratejik yönetimin bir gereği olarak iç kontrol standartları kapsamında kurumsal risk çalışmaları, prosedürlerin belirlenip kurumsal raporların yayınlanması, ön mali kontrol çalışmalarının yapılması ve kurumda iç denetçilerin çalıştırılması hususlarına önem verilmelidir. Bu sayede stratejik yönetim üzerinde güçlü bir etkisi olacaktır.
Bookkeping approaches for crypto currencies
(PressAcademia, 2021-07-30) Teker, Suat; Ergül, Yağmur
Purpose- In the New World order, we are experiencing a period in which we meet cryptocurrencies that are physically non-existent and can be transferred without public control, without the need for intermediaries. Everything that has financial value in essence is the subject of accounting. Since crypto currencies also have a financial value, they must be recorded, accounted and taxed. This study examines how crypto assets can be defined and reflected in accounting records in accordance with the definitions. Methodology- Since the concept of crypto money has started to enter commercial life in recent years, the literature resources are very limited, and there are many issues that have not yet become certain in terms of legislation, the approaches developed for the accounting of crypto currencies in this study are a suggestion. Findings- In the analysis made on the basis of current literature reviews, crypto currencies can be defined as money, other liquid assets, marketable securities, inventory or other intangible assets. The accounting transactions in accordance with these definitions are explained with the help of a hypothetical example. Conclusion- The opinion is that it would be appropriate to define crypto currencies as marketable securities in line with today's intensive usage area and acquisition purpose.
Determinants of Bitcoin price movements
(Suat Teker, 2024-07-30) Teker, Dilek; Teker, Suat; Demirel, Esin
Purpose- Investors want to include Bitcoin in their portfolios due to its high returns. However, high returns also come with high risks. For this reason, the volatility prediction of Bitcoin prices is the focus of attention of investors. Because Bitcoin's volatility is used as an important input in portfolio selection and risk management. This means that the models to be used in predicting Bitcoin volatility increases the importance of performance. In this research; A comparative examination of the models applied for Bitcoin shows an effective performance in volatility prediction. It is very important for evaluation. The aim of this study is to model Bitcoin price returns and to examine future return predictions and return directions using historical Bitcoin prices. Methodology- Many models have been used in studies on financial instruments and price predictions. Models such as linear and nonlinear regression, Random Walk Model, GARCH and ARIMA fall into this category. Nonlinear econometric models such as ARCH and GARCH are used for financial time series with variable volatility. These models assume that the variance is not constant. In this study, first Bitcoin price returns for the period between January 2020 and December 2023 will be modeled with the GARCH model, and then the ARCH-GARCH models will be used for future prediction of returns for the period between January 2024 and June 2024. Finally, the actual values will be compared with the forecasted values. In other words, the primary aim of this study is to use the daily Bitcoin closing price between May 2020 and December 2023 to estimate the returns for the periods of 2024 and compare it with the actual returns. Findings- The analysis reveals that GARCH Model results showed that in the mean and variance equations, it is seen that all variables are except intercept of the mean equation significant according to the error level of 0.05. Namely, the reaction and persistence parameters are significant accourding to 0.05 in the variance equation. Both the coefficient of the reaction parameter and the coefficient of the persistent parameter are higher than zero (positive). Also, the coefficient of the reaction parameter plus the coefficient of the persistent parameter approximately equals 0.72. That is, it is lower than 1 and higher than zero (positive). The level of persistence is not too high. So, we do not think about non-stationary variance in the model. Reaction parameter’s coefficient is 0.13. And persistence parameter’s coefficient is 0.58. As we can see, persistent parameter is much higher than reaction parameter. That is, when there is a new shock that creates the persistent parameter, that shock will be in effect for a long time, it will not disappear immediately. That is, a significant part of the shock that occurs in one period flows into the next period. After determining the appropriate mean and variance models, a forecast is made using Automatic ARIMA forecasting for BITCOIN return forecasting. This forecast is made for the first five months of 2024, without adding the actual values of the first five months of 2024 to the data. The program ranks the most appropriate model. The program chose GARCH(3,3) as the most appropriate model in "bitcoin return prediction". Conclusion- The results of the test applied in the study can be summarized that the unit root test results showed that it was necessary to work with return series. GARCH(1,1) model results show when there is a new shock that creates the persistent parameter, that shock will be in effect for a long time, it will not disappear immediately. That is, a significant part of the shock that occurs in one period flows into the next period. According to GARCH automatic forecasting results, the best GARCH model that models Bitcoin return is the GARCH(3,3) model. According to these model results, although the slopes of the actual and forecasted return series move in the same direction, the model remains weak for forecasting. In future studies, it may be recommended to estimate Bitcoin returns with non-linear models.
Digital era for universities: soon or far
(PressAcademia, 2023-07-30) Eşkinat, Ali; Teker, Suat
Purpose- Over the Covid-19 crises, most universities keep increasing the use of hybrid model at various levels in all disciplines in their education system forced by the market demand. This paper reviews the evolution of university generations from university 1.0 to university 4.0 using a historical point of view. This paper intends to clarify whether digital era for universities, namely University 5.0, is soon or far advocating that a large number of completely digital universities may breakout and reach everywhere in the world with no barriers of language, time and locations, and competing with local and traditional universities in all sense after year 2030. Methodology- The study employs an online survey via convenience sampling based on quantitative research method. Employers/Managers, Academics and formal University Students were selected as three target population group located all around Turkiye. The aim was to test the 5 hypotheses of this study to clarify the time of digital era for universities. Findings- The analysis reveals that the 5 hypotheses are accepted and seen as valid. The empirical results show a significant difference between the gender variable and the importance given to digital education. Moreover, there was a significant difference in the mean scores of the significance of digitalization and the importance given to digital education based on education level variable. Then, there were differences in the significance of digitalization and the importance given to digital education concerning the social status variable in the collected data. Notably, a linear and significant relationship was revealed between the importance given to digital education by participants and the importance they attributed to digitalization. Furthermore, a linear and significant relationship was found between the importance given to digital education and the importance given to university education. Under these circumstances, the results reveal that digital education is concerned as a fact of digital era and higher education institutions are not immune of this transformation. Conclusion- Based upon the analysis, it can be concluded that the traditional university system will be evolved into a digital university system in a not-too-distant future. In other words, traditional prestigious universities are expected to continue whereas digital universities appear as destructive competitors. For this reason, it may be argued that universities will increase to provide hybrid model education depending on the market demand until 2030, whereby it will be applied at different rates in education disciplines, such as of medicine, engineering, social sciences and many others. After 2030 traditional universities will continue to use blended learning whereas digital higher education institutions will start their inevitable growth.

The e-commerce sector is witnessing a spike in demand as consumers order essential items such as food and clothes through e-commerce websites, where most consumers prefer the digital mode of payment.Transition towards the cashless economy, emergence of new online financial institutions, a decentralized monetary governance with the adoption of blockchain and cryptocurrencies are envisioned. Advancements in payment technologies as well as digital payment systems adoption will create momentum and create further investments towards digitalization of monetary exchange. Conclusion- It is concluded that evolution of digital payment systems will extend convenience, return, convergence, cross-border and timelimitless transaction. Inclusion of the unbanked is expected to drive growth and create new opportunities. There is a clear transition towards a cashless economy with the increasing adoption of digital payment systems by all spenders. Speed, privacy, convenience, security and decentralization will mean a wider inclusion for all global citizens; even including some unbanked population. Decentralization and blockchain will mean a blur in distribution of wealth, some money leaving the traditional banking systems. Digital payment systems provide a wide range of transaction options to its users; swiped credit cards, electronic checks, mobile wallets and contactless payment. By 2050s, the circulation of physical money is expected to vanish, leaving its place to virtual currencies changed on digital platforms.

The effects of policy rate announcements on the exchange rates
(PressAcademia, 2024-01-15) Teker, Suat; Teker, Dilek; Demirel, Esin
Purpose- Exchange rate is the value of a country's national currency against foreign national currencies. In this context, the exchange rate is considered an important macroeconomic indicator in evaluating the country's economy. The failure to control the exchange rate may damage economy significantly. It is possible to understand this from the 2001 crisis in Turkey, known as 'Black Wednesday', and the foreign Exchange crisis that started in Thailand in 1997 and affected many East Asian countries. Interest rate is one of the critical determinants affecting the exchange rates. Therefore, changes in interest rates are expected to affect the level of exchange rates. When there is an increase in interest rates, foreign capital flow is expected for that particular country. Hence, a decrease in exchange rates is expected for the excess capital flows. This study aims to analyze the relationship between exchange rates and interest rates, considering the last 10 announcements of the interest policy of the Central Bank of the Republic of Turkiye. These announcements are between January 19, 2023 and October 26, 2023. The study used the TL/USD exchange rates and 10-year government bond interest rates to measure the relationship in between these two variables. Methodology-The aim of this study is to analyze the relationship between the dollar exchange rate and government bond interest rates for Turkiye. For this purpose, data is collected for the days when the last 10 policy rates published by the CBRT were announced. Data is obtained investing.com. Vector Autoregression (VAR) is used to measure the relationship in between two variables. The VAR system is based on empirical regularities embedded in the data. The VAR model may be viewed as a system of reduced form equations in which each of the endogenous variables is regressed on its own lagged values and the lagged values of all other variables in the system. Vector Autoregressive models are widely used in time series research to examine the dynamic relationships exist in between variables that interact with one another. In addition, VAR models are viable forecasting tools used often by macroeconomic or policy -making institutions. . In this study first, the stationary levels of the variables are determined by using Unit Root Test. Second, pre-tests of autocorrelation, heteroscedasticity and normality are conducted for the validity of the VAR model. Third, the short-term relationship between variables is tested by using VAR Granger Causality Test. Fourth, VAR analysis is utilized by applying Impulse-Response Analysis and Variance Decomposition Analysis . And finally, the long-term relationship between variables is tested by using Johansen Cointegration Test. Vector Autoregressionmodel is employed in this study. Findings- According to the results of Granger Causality test, government bond interest rates strongly affect the changes of exchange rate. However, there is no causality from exhange rates to interest rates. Therefore, the changes of interest rates are the main determinants of the changes of exchange rates in this short period. The results of Impulse-Response Test show that an unexpected shock (an unexpected increase) in government bond interest rates affects the exchange rates and increases it significantly. More, an unexpected increase in the exchange rates causes the interest rates on government bond to increase. The results of the variance decomposition test show that 50% of the change in the variance of the exchange rates in the first period is explained by changes in bond interest while 30% of the change in the variance of bond interest rates is explained by the changes in exchange rates. The results of Johansen cointegration test support that there is a stable long-term relationship between dollar exchange rates and government bond interest rates. Conclusion-This study focuses on the relationship between government bond interest rates and the dollar exchange rates in Turkiye for the last 10 policy interest rates announcements by Cenral Bank of Turkiye. In summary, the changes in interest rates on bonds affect the changes in exchange rates more. Data for the days that the CBRT issued the last ten policy rates is gathered for this purpose. The association between two variables is measured using Vector Autoregression (VAR). According to overall results, the changes in interest rates on bonds affect the changes in exchange rates more.

Bu çalışmada, maddi duran varlıklar konusunu kapsayan muhasebe standartları karşılaştırmalı olarak incelenmiş ve gerçek firmaların bu konu ile ilgili uygulamaları analiz edilmiştir. Bulgular- Maddi duran varlıkların elden çıkarılması konusunda, Türkiye Muhasebe Standartları 16 ve Türk vergi mevzuatında yer alan hükümler karşılaştırıldığında; elden çıkarılan maddi duran varlıkların hangi şekilde bilanço dışı bırakılacağı konusunda benzerlik ve farklılıkların olduğu görülmektedir. Sonuç- Çalışmanın kapsamında maddi duran varlık konusu kısmen ele alınmış olup, elden çıkarılan maddi duran varlıklara ilişkin var olan mevcut uygulamalar üzerinde ağırlıklı olarak durulmuş ve uygulamaya yansıyan sonuçları incelenmiştir.
Evolution of business models during the Covid-19 pandemic
(PressAcademia, 2022-07-30) Teker, Suat; Örendil, Emre
Purpose - The purpose of this study is to propose a comprehensive definition for business models, reviews and summarizes the findings of a previous work by Guckenbiehl and Corral de Zubielqui (2022) about how business models have evolved by providing insights from reshaped businesses during the COVID-19 pandemic. Methodology - In this study, an extensive literature review is followed to learn about definition of business models and how business model have been adapted or even innovated during the times of the COVID-19 pandemic. Findings - Construction of a well-planned business model is a requirement for an organization to reach success. In the times of disruptive events, business models go through adaptive or innovative changes which is a necessity for survival and further success. It is observed that organizations generate different responses to crises (e.g., the COVID-19 pandemic) in means of business model changes. The understanding of these differences is facilitated by the aforementioned work through grouping organizations in six different clusters. Conclusion - The structure of a business model prior to the COVID-19 pandemic was also one of the determinants of a business’s response to the pandemic. Businesses either made no changes in their business models, or made notable innovations, or little adaptations in response to the disruptive environment.
Export potential of Turkish SMEs
(Suat Teker, 2024-07-30) Teker, Suat; Teker, Dilek; Orman, Irmak
Purpose- Digital channels are gaining more and more share from trade and commerce, especially after Covid 19 pandemic. People have adopted to online buying and marketplaces became important retailing tools for manufacturers. E-commerce is rising not only in closed commercial areas but also across different countries, even continents with developments in cross-border e-commerce. Governments, global digital platforms, consumer habits are creating and supporting the demand of buying online from anywhere and numbers are showing that this creates an opportunity for Turkish businesses to become exporters. This study aims to highlight the potential for small and medium sized businesses in Turkey to become exporters. Methodology- The study examines historical export growth data of Turkey in detail using secondary data. The historical data is used to make a projection for future and highlight the potential of growth for Turkish SMEs. Current marketplace platforms’ business models are also examined and carefully analyzed to present an understanding of the potential business models. Findings- The numbers are showing that Turkish exports are growing in Europe and USA. Capex heavy industries have the highest share among the exports but e-commerce is also growing. Some industries like textile, jewellry and small appliences has a higher growth potential withing cross border e-commerce. Conclusion- Adoption to online retail is getting higher and higher. More people are buying from online marketplaces and the origin of the transaction is losing its importance with one-day deliveries. It is important to open shops not only physical but also on different platforms. It is easier for business owners to sell across the world and become exporters. By having international customers, businesses distribute regional risks and also become financially stronger. It is important for Turkish SMEs to understand their risks and seek international growth opportunities, such as doing exports. Turkey’s unique geographical location is a very important asset but Turkish businesses should keep in mind that all international producers are now seeking opportunities to create through online platforms.
Financial inclusion and economic development: Turkey and Greece
(PressAcademia, 2023-02-01) Teker, Suat; Teker, Dilek; Güzelsoy, Halit
Purpose- Financial inclusion means individuals and businesses have access to useful and affordable financial products and services to deliver their needs in a responsible and sustainable way. A financial sector is measured and compared on four main features; debt is the size of financial institutions, access is the access and use of financial services by the users, efficiency is the efficiency in the provision of financial services, and stability is the stability in the provision of financial services. The purpose of this paper is to measure the level of financial inclusion of Turkey and Greece from 2000 to 2020 and compare its relationship with the economic growth and income inequality of both countries. Methodology- The World Bank data covering the 2000-2020 period is extracted from Turkey and Greece from the world bank report. The whole financial system for both countries is defined as a combination of banks, nonbanks financial institutions, and stock exchange markets. The related indicators for each of the subsectors of the financial system are determined for banks, nonbanks financial institutions, and stock exchange markets. Thus, 32 indicators for banks, 6 indicators for nonbanks, and 16 indicators for stock exchange markets are determined for the financial inclusion index. All indicators are in percentages. All individual indicators are summed for the computation of subsectoral indexes and then the growth rate in each subsectoral indexes are computed. The growth rates of each subsectoral index are summed and weighted by the subsectoral asset sizes or trading volüme. Finally, the causal relationship between the financial inclusion index, Gini coefficient, Poverty Headcount ratio, and GDP per capita was examined. Findings- The average growth rate for the financial inclusion index for the 21 years is 2,83% for Turkey and 0,97% for Greece. According to the analysis, we found that the financial inclusion index Granger-cause GDP per capita, Gini index Granger-cause financial inclusion index and there is a bidirectional relationship between the financial inclusion index and Poverty Headcount ratio for Turkey. On the other hand, there is a bidirectional relationship between GDP per capita and the financial inclusion index and a bidirectional relationship between the financial inclusion index and the Poverty Headcount ratio for Greece. Conclusion- Financial inclusion simply means a larger size of financial institutions and a variety of financial products and services available for the use of adult individuals, businesses, and governmental agencies. Economic growth is supported and accelerated by an increase in financial inclusion. The empirical analysis supports the literature that the growth in the financial inclusion index enhances a higher growth in GDP and a much higher growth in GDP per capita for both Turkey and Greece. The project titled “Istanbul as an International Financial Center” may easily improve the level of financial inclusion in Turkey.
Financial inclusion for selected OECD countries

Purpose- Financial inclusion is defined as a process that ensures the ease of access, availability, and usage of the formal financial system for all members of an economy by emphasizing the use of accessibility and availability of financial services. A financial sector is measured and compared on four main features; debt is the size of financial institutions, access is the access and use of financial services by the users, efficiency is the efficiency in the provision of financial services, and stability is the stability in the provision of financial services. Financial inclusion, in short, is adults' access to and use of financial services. This study aims to measure the financial inclusion level for selected OECD countries from 2010-2021. Also, this study aims to estimate the effect of financial inclusion on economic growth and income inequality for selected countries. Methodology- The data used in this study cover a range of variables related to financial inclusion from various institutions, including the IMF-Financial Access Survey (IMF-FAS), the World Bank - World Development Indicators (WB-WDI), the World Bank - Global Financial Development Database (WB-GFDD) and the Standardized World Income Inequality Database (SWIID). These variables provide insights into the dimensions and determinants of financial inclusion and their impact on economic and social outcomes for selected OECD countries. In the study, we run panel data regressions for each group separately, using GDP per capita as the dependent variable to determine the impact of the Financial Inclusion Index on economic growth. We also construct two different models for each group of countries with and without the added control variables into the models. Findings- The analysis reveals that the effect of financial inclusion on economic growth is negative for all groups of countries. The impact is significant for Group 1 and Group 2. The magnitude of coefficients changes when we add control variables to the model. However, it does not change the significance level of the coefficients. The magnitude of the coefficients increases as countries’ per capita income increases. At the same time, the effect of financial inclusion on the GINI index is significant only in the model for Group 3 with control variables. The sign of the impact is negative. It implies that the GINI index decreases as the financial inclusion index increases. So, the effect of financial inclusion on income inequality is positive for countries in Group 3. Conclusion- The empirical results did not support the relationship between financial inclusion and economic growth (GDP per capita). These results may be explained by advocating the financial sector's quick and fundamental digital transformation. Hence, the rules for availability, accessibility, and usage of financial products and system are completely changed in the past ten years. On the other hand, the relationship between financial inclusion and income inequality, measured by GINI Index, is consistent with the literature only for Group 3 countries (developing countries). The increase in the gap between rich-developed and developing countries may explain these results. An increase in financial inclusion still supports adjustments in income inequality in developing countries, but its effect is disappeared in developed countries in the last 12 years.
Financial inclusion: the case of Turkey

Purpose- Financial inclusion is defined as a process that ensures the ease of access, availability and usage of the formal financial system for all members of an economy by emphasizing the use of accessibility, availability of financial services. A financial sector is measured and compared on four main features; debt is the size of financial institutions, access is the access and use of financial services by the users, efficiency is the efficiency in the provision of financial services, stability is the stability in the provision of financial services. Financial inclusion, in short, is adults' access and use of financial services. The purpose of this paper is to measure the level of financial inclusion of Turkey for the period of 2000-2017. Methodology- The World Bank data covering 2000-2017 period is extracted for Turkey. The whole financial system of Turkey is defined to be a combination of banks, nonbanks financial institutions and exchange markets. The related indicators for each of the subsections of the Turkish financial system are determined for banks, nonbanks and exchange markets providing a continued data stream. Thus, 32 indicators for banks, 6 indicators for nonbanks and 16 indicators for exchange markets are determined for the financial inclusion index for Turkey. All indicators are in percentages. All individual indicators are summed for the computation of subsectional index and then the growth rate in each subsectional index is computed. Finally, the growth rates of each subsectional index are summed and weighted considering the subsectional asset sizes or trading volume. Findings- The highest growth years in financial inclusion of banks; 15.26% in 2002, 8.05% in 2009, and 4.42% in 2014. The lowest growth years in financial inclusion of banks; -10.36% in 2001 and -2.00% in 2008. The average growth rate for banks for the 17 year period is 2.14%. The highest growth years in financial inclusion of nonbanks; 24.47% in 2004, 28.37% in 2006, 26.34% in 2009, 53.07% in 2010, and 30.86% in 2014. The lowest growth years in financial inclusion of nonbanks; -18.74% in 2001, -22.95% in 2011 and -11.39% in 2016. The average growth rate for nonbanks for the 17 year period is 6.19%. Conclusion- Financial inclusion simply means a larger size of financial institutions and a variety of financial products and services available for the use of adult individuals, businesses and governmental agencies. The existing literature advocate that the economic growth can be accelerated by an increase in financial inclusion. The empirical analysis for Turkey supports the literature where the growth in financial inclusion index enhances a higher growth in GDP and a much higher growth in GDP per capita. The project titled “Istanbul as an International Financial Center” may easily improve the level of financial inclusion in Turkey. For a sustainable economic growth and a fair income distribution in Turkey, the policy makers and administrators should set the rules and regulations to improve the financial inclusion.
