An Alternative Mean Reversion Test for Interest Rates
(Central Bank Republic Turkey, 2018) Ozel, Ozgur; Ilalan, Deniz; 01. Çankaya Üniversitesi; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi
A number of empirical studies assert that interest rates are governed by unit root processes rejecting any form of reversion to a long term mean by resorting to certain tests, among which the Augmented Dickey Fuller (ADF) is the most widely used one. In this study, we propose an alternative testing methodology that can be applied along with ADF test, in the sense that there are times where it can capture stationarity when the other fails to do so. Moreover, our test has more power than ADF test. As an application to real-data, we consider 10-year US and Turkish T-bond rates. (C) 2017 Central Bank of The Republic of Turkey.

Asymmetric Smooth Transition in Cds Spreads: Evidence From Latvia
(Allied Business Academies, 2019) Akdoğan, E.C.; Akdoğan, Ece Ceylan; 17735; Bankacılık ve Finans; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
This paper investigates the predictability of CDS premiums and thus addresses weak form informational efficiency of CDS markets through examining the statistical properties of Latvian CDS spreads in-between 01:2006-08:2017 by concentrating on stationarity issues. The findings for the Augmented Dickey Fuller test fail to reject the presence of unit root indicating that the CDS market is weak form efficient while nonlinear tests of Kapatenios, Snell and Shin, and Sollis claim the opposite, demonstrating a smooth transition in general, and asymmetric smooth transition in particular. Additionally, the results of Perron and Zivot-Andrews tests identify no structural break as well for robustness. These results underline the necessity of accounting for nonlinearities in CDS premiums to grasp the predictability dynamics better. © 2019, Academy of Accounting and Financial Studies Journal.

Can Us Wage Increases Be Regarded as A\rleading Indicator for Bond Rates
(2020) Acar, Elif Oznur; Özşuca, Ekin Ayşe; 237965; 48566; 03.06. Uluslararası Ticaret ve Finansman; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
After the subprime meltdown, the Federal Reserve focused its attention on US non-\rfarm payroll data in order to pave the way for its fund rate hikes. As time went by,\rthe Federal Reserve deemed particularly one sub-component of this data, namely the\rincrements on average weekly wage growth as a proxy for in\ration and thus a plausible\rexplanation for raising the interest rates. In that aspect, we decide to elaborate on this\rissue further and examine whether this implemented strategy indeed had a re\rection in\rthe real market. For doing so, we intend to determine whether there is any causality\rrelation in either direction between US average weekly wage increases and 10-year\rTreasury Bond rates. We utilize the Toda-Yamamoto causality approach and come\rup with a statistically signicant result between wages and bond rates. For robustness,\rwe also consider the unemployment rate and consumption expenditures as independent\rvariables.
The Causal Relationship Between Stock Markets and Policy Uncertainty in Oecd Countries
(Bc Grup inc, 2017) Pirgaip, Burak; 252136; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
In this study, we examine the causal relationship between economic policy uncertainty (EPU) and stock market prices in OECD countries. We provide strong evidence that stock markets mostly Granger cause EPU. Such causality may also exist in the opposite direction for a few cases and we find no causality in some countries as well. Our results do not provide any support for bidirectional causality.

Economic Exposure of Emerging Market Firms
(National Academy of Management, 2015) Karadagli, E.C.; Akdoğan, Ece Ceylan; 17735; Bankacılık ve Finans; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
Although foreign exchange risk inherits more severe exposures for emerging market firms, past empirical research addressing foreign exchange exposure is mainly concentrated on firms operating in developed economies. This paper examines the impact of exchange rate fluctuations on firm value at an emerging market through focusing on economic exposure of Turkish listed firms. The findings indicate that depreciation of Turkish lira against the euro, the US dollar and the basket currency significantly deteriorates firm value in a current month while significantly enhances firm value during the next month. When the overall impact of Turkish lira depreciation on the value of Turkish companies is considered, it is observed that the weakening of the home currency has a positive effect on firm’s value. © Ece C.

Elliott Wave Principle and the Corresponding Fractional Brownian Motion in Stock Markets: Evidence From Nikkei 225 Index
(Pergamon-elsevier Science Ltd, 2016) Ilalan, Deniz; 01. Çankaya Üniversitesi; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi
This paper examines one of the vital technical analysis indicators known as the Elliott wave principle. Since these waves have a fractal nature with patterns that are not exact, we first determine the dimension of them. Our second aim is to find a linkage between Elliott wave principle and fractional Brownian motion via comparing their Hausdorff dimensions. Thirdly, we consider the Nikkei 225 index during Japan asset price bubble, which is a perfect example of an Elliott wave. (C) 2016 Elsevier Ltd. All rights reserved.

An Empirical Analysis of Household Education Expenditures in Turkey
(Pergamon-elsevier Science Ltd, 2016) Cilasun, Seyit Mumin; Acar, Elif Oznur; Gunalp, Burak; 01. Çankaya Üniversitesi; 03.06. Uluslararası Ticaret ve Finansman; 03. İktisadi ve İdari Birimler Fakültesi; 03.07. Yönetim Bilişim Sistemleri
Using Turkish Household Budget Surveys from 2003, 2007 and 2012, this paper investigates the determinants of household education expenditures within an Engel curve framework. In particular, we estimate Tobit regressions of real educational expenditures by income groups using a number of household characteristics (i.e. rural residence, employment status, age, educational attainment of the household head, household size, share of female students and primary school students in the household, and total number of students in the household) to examine if and to what extent the determinants of educational expenditures differ by income groups; income elasticities of educational spending evolves over time; and children from middle-class and poor families can benefit enough from educational opportunities. The estimated expenditure elasticities have lower values for the top- and the bottom income quartiles while they have larger values for the middle-income quartiles. The results also show that for all income groups the expenditure elasticity of education increases over time, indicating that Turkish households allocates greater share of their budgets to education expenditures.

An Empirical Examination of the Generalized Fisher Effect Using Cross-Sectional Correlation Robust Tests for Panel Cointegration
(Elsevier Science Bv, 2015) Yuksel, Aydin; Omay, Tolga; Yuksel, Asli; 19320; 08.02. Çankaya Meslek Yüksekokulu; 08. Meslek Yüksekokulları; 01. Çankaya Üniversitesi; 03.04. İşletme; 03. İktisadi ve İdari Birimler Fakültesi
This study examines the generalized Fisher hypothesis as applied to common stocks by using the recently proposed second generation panel cointegration tests. Unlike their predecessors, these new tests assume the existence of cross-section dependence in the data. For the sample analyzed, we report that these new tests, but not their predecessors, provide strong support for the existence of cointegration between stock and goods prices. Moreover, further analysis cannot reject the hypothesis that the cointegration relation is linear. Finally, our Fisher coefficient estimates are in the range between 0.68 and 1.27 and give support to the generalized Fisher hypothesis. (C) 2014 Elsevier B.V. All rights reserved.

Energy Consumption and Growth: New Evidence From a Non-Linear Panel and a Sample of Developing Countries
(World Scientific Publ Co Pte Ltd, 2015) Apergis, Nicholas; Ozcelebi, Hulya; Omay, Tolga; 08.02. Çankaya Meslek Yüksekokulu; 08. Meslek Yüksekokulları; 01. Çankaya Üniversitesi
This paper investigates the relationship between economic growth and energy consumption through non-linear causality tests. Eight developing countries from Europe and Central Asia spanning the period 1993 to 2008 are selected for the purpose of panel empirical analysis. Panel unit root and panel cointegration tests with and without considering cross section dependency (CD) problems are implemented. Next, linear panel cointegration tests are employed and, finally, a two-regime Dynamic Panel Smooth Transition Vector Error Correction (PSTRVEC) model is estimated for testing the presence of non-linear short-and long-run causality. To this end, a new estimator, called the Dynamic Non-linear Pooled Common Correlated Effect Estimator (DNPCCEE) is proposed. The empirical findings indicate that short and long-run causalities are regime-dependent.

Exchange Rate Risk and International Trade: the Role of Third Country Effect
(Elsevier Science Sa, 2018) Tunc, Cengiz; Solakoglu, M. Nihat; Babuscu, Senol; Hazar, Adalet; 265921; 161529; 117425; 219046; 03.07. Yönetim Bilişim Sistemleri; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
Using the recently launched Exporter Dynamics Database of the World Bank, this paper empirically investigates the role of external exchange rate risk (third-country effect) on trade flows between countries. We find a strong positive influence of external exchange rate risk on exports to a specific destination. However, the effect is more observable in advanced destination countries, countries with low bilateral exchange rate volatility in comparison to external exchange rate volatility, and countries in which export is concentrated among a small number of firms.

Exchange Rate Volatility and Trade: External Exchange Rate Volatility Matters
(World Scientific Publ Co Pte Ltd, 2020) Babuscu, Senol; Hazar, Adalet; Solakoglu, M. Nihat; Tunc, Cengiz; 161529; 03.07. Yönetim Bilişim Sistemleri; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
We investigate the role of external exchange rate volatility in export in addition to the effect of bilateral exchange rate volatility using country-, sector-, and destination-specific detailed export data of the World Bank Exporter Dynamics Database. The results show that while the bilateral exchange rate volatility has a depressing effect on export, the external exchange rate volatility generates trade-promoting effect on export. However, the magnitude of the effect depends on trade intensity between countries. Furthermore, while the role of external exchange rate volatility diminished after the Global Financial Crisis, the effect of its volatility has become larger. Finally, external exchange rate volatility has a larger trade-promoting effect on export in the presence of high volatilities than the effect in the presence of low volatilities.

The Formal/Informal Employment Earnings Gap: Evidence From Turkey
(Emerald Group Publishing Ltd, 2016) Acar, Elif Oznur; Tansel, Aysit; 48566; 01. Çankaya Üniversitesi; 03.06. Uluslararası Ticaret ve Finansman; 03. İktisadi ve İdari Birimler Fakültesi
This study investigates the formal/informal employment earnings gap in Turkey. We focus on the earnings differentials that can be explained by observable characteristics and unobservable time-invariant individual heterogeneity. We first, estimate the standard Mincer earnings equations using ordinary least squares (OLS), controlling for individual, household, and job characteristics. Next we use, panel data and the quantile regression (QR) techniques in order to account for unobserved factors which might affect the earnings and the intrinsic heterogeneity within formal and informal sectors. OLS results confirm the existence of an informal sector penalty almost half of which is explained by observable variables. We find that formal-salaried workers are paid significantly higher than their informal counterparts and of the self-employed confirming the heterogeneity within the informal employment. QR results show that pay differentials are not uniform along the earnings distribution. In contrast to the mainstream literature which views informal self-employment as the upper-tier and wage-employment as the lower-tier, we find that self-employment corresponds to the lower-tier in the Turkish labor market. Finally, fixed effects estimation indicates that unobserved individual characteristics combined with controls for observable characteristics explain the pay differentials between formal and informal employment entirely in the total and the female sample. However, informal sector penalty persists in the male sample.

Globalization, Firm Performance and Group Affiliation in Emerging Markets: Evidence From Turkey
(Asers Publishing, 2013) Akdoğan, Ece Ceylan; Karadagli, Ece Ceylan; 17735; Bankacılık ve Finans; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
Although the process of globalization deeply affects businesses in all aspects, unfortunately, the firm level effects of globalization are highly unexplored in the literature. This research aims to explore how the overall globalization level of a country as well as her economic, her political and her social globalization levels affect the performance of both the group affiliated and the unaffiliated firms, operating in this business environment by using pooled panel analysis. To search for the potential differences that may prevail between the firm performance effects of globalization on the group affiliated firms and on the unaffiliated firms, it focuses on Turkish listed companies for the period 2002-2009. The findings of the study indicate that while globalization improves the stock returns of both the group affiliated and the unaffiliated firms, it deteriorates the operational income of both groups of firms. The findings also imply that although the effects of economic and political globalization do not seem to differentiate much between the group affiliated and the unaffiliated firms, social globalization may be argued to affect the operating incomes and the firm growth rates of group affiliated and unaffiliated firms differently. Last but not least, the findings suggest that the most influential dimension of globalization in terms of its effects on firm performance for Turkish companies seems to be the economic globalization.

How Globalization Affects the Operational Efficiency of Emerging Market Firms?: a Comparative Analysis on Turkish Smes
(Univ Oviedo, 2018) Akdogan, Ece Ceylan; 17735; 01. Çankaya Üniversitesi; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi
This paper examines the impact of globalization on the operational efficiency of emerging market firms by concentrating on the financial outcomes of a firm's main operations through focusing on operating income and cash conversion cycle as well as on their possible causes in an emerging market, Turkey. The findings indicate that globalization significantly deteriorates the operating income and lengthens the cash conversion cycle of Turkish firms. Besides, globalization is found to increase sales of SMEs and decrease sales of large companies significantly and the impact on operating income of large companies is observed to be stronger. Globalization is also found to lead a softening in Turkish firm's terms of sales and enable Turkish SMEs to benefit from better terms of purchase.

How Stock Markets Become Desensitized To Terror
(Emerald Group Publishing Ltd., 2017) Ilalan, D.; 01. Çankaya Üniversitesi; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi
Purpose-A widely accepted belief indicates that terror activities have negative impact on stock markets. Contrary to numerous empirical studies, the purpose of this paper is to consider this issue from another point of view in the sense that markets can become desensitized to terror. Design/methodology/approach-Here, instead of directly analyzing the existing data, the stochastic nature of the events is taken into consideration. Findings-The author compares three countries and found out that the correlation between terror and stock markets is almost nil when terror events become a commonplace. Originality/value-This paper applies mean reverting stochastic processes to terror incidents and brings out interesting results. © Emerald Publishing Limited.

Purpose-This paper aims to answer how effective the loan-to-value (LTV) regulation has been since 2011 for conventional and Islamic (participation) banks in Turkey in terms of curbing mortgage loan growth and delinquency[1]. Design/methodology/approach-The authors first use unit root tests and tests of difference in loan and property price data in pre-LTV and post-LTV period. Second, the authors follow Chow test and ordinary least squares regression analyses to test for a structural break when sensitivity of mortgage loan and delinquency growth changes to property price changes considered. Findings-The authors find that two periods are statistically different, while the significance level is lower for Islamic banks. Moreover, loan growth has become less responsive to property price increases; delinquency sensitivity to property price changes has significantly increased in the post-LTV period for conventional banks, while this is not the case for Islamic (participation) banks. Originality/value-This paper not only increases empirical evidence regarding the effectiveness of LTV ratio policy but also fills the gap in the literature by providing a comparison between conventional banks and Islamic (participation) banks.

Managing Working Capital Efficiency in Turkish Agribusinesses and the Impact of Globalization: Insights From an Emerging Market
(Wageningen Academic Publishers, 2019) Dinc, Dilek Temiz; Akdogan, Ece C.; 52039; 03.01. Bankacılık ve Finans; 03.06. Uluslararası Ticaret ve Finansman; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
The efficiency of working capital is a major determinant of firm profitability. So, the grasp of working capital dynamics is extremely important for managers, but also for policy makers, since inefficient working capital management is an important source of industrial sickness. This study focuses on the profitability impacts of working capital policies of Turkish agribusinesses, and aims to investigate the potential effects of globalization on these interrelated relationships. The findings obtained from pooled panel analyses demonstrate that Turkish agribusinesses can enhance their profitability and value by adopting a conservative working capital policy through lengthening the cash conversion cycle up to an optimal level. Besides, globalization is found to deteriorate their efficiency and profitability where economic globalization seems to have the highest impact raising questions on the effectiveness of Turkish agribusinesses in coping with competition. Thus, both the managers and the policy makers should concern with the competitiveness impacts of globalization.

Market Reaction To Grouping Equities in Stock Markets: an Empirical Analysis on Borsa Istanbul
(Elsevier, 2017) Karan, Mehmet Baha; Pirgaip, Burak; Yildiz, Yilmaz; 252136; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
The main aim of this study is to investigate the market reaction to stock grouping announcements in Borsa Istanbul which requires stocks to be classified into groups "A ", "B" and "C" according to their market capitalization and floating rates. By utilizing event study analysis, our results suggest that grouping announcements have significant effect on stock prices and trading volume. The event day positive (negative) relationship between abnormal return and volume for the upgraded (downgraded) stocks supports the downward sloping demand curve hypothesis. Moreover, findings also suggest that stocks which are upgraded to Group A are exposed to more attention which is in line with the attention hypothesis. The reverse is valid for the downgraded firms. We find no evidence of price reversals and long-term symmetrical liquidity effect which lead us to reject price pressure and liquidity hypotheses. Finally, we reach controversial evidence for the information hypothesis. Copyright (c) 2017, Borsa Istanbul Anonim Sirketi. Production and hosting by Elsevier B.V.
