An Empirical Examination Of The Generalized Fisher Effect Using Cross-Sectional Correlation Robust Tests For Panel Cointegration
(Elsevier Science Bv, 2015) Omay, Tolga; Omay, Tolga; Yuksel, Asli; Yüksel, Aslı; Yuksel, Aydin; 19320; Çankaya Meslek Yüksekokulu; İşletme
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.
An Outline of Skilled Emigration from Turkey to OECD Countries: A Panel Data Analysis
(2017) Acar, Elif Öznur; 48566; Uluslararası Ticaret ve Finansman
Turkey provides rich evidence for the current international migration trends given its economic and demographic dynamics. The number of people moving overseas to settle permanently has been following an increasing trend in the recent decades, particularly remarkable for skilled and female groups. However, given the micro-level data limitations the migration outlook of Turkey is still quite bleak. The aim of this paper is to fill this gap and analyze the relationship between migration and human capital in the context of Turkish immigrants. First, aggregate trends of the Turkish emigrants in the 20 OECD destination countries by gender and educational level over the 1980-2010 period are examined using the IAB Brain Drain dataset. Next, a random effects panel estimation is applied to scrutinize the underlying dynamics of observed migration patterns adopting economic size, unemployment, demographic profile, urbanization and proximity as explanatory variables. The results reveal that gender, time and education are found as significantly related to international mobility trends, and the substantially left-skewedness of the distribution of Turkish emigrants along educational level is gradually fading away over time.

Can US Wage Increases be Regarded as a Leading Indicator for Bond Rates?
(2020) Acar, Elif Öznur; Acar, Elif Oznur; Özşuca, Ekin Ayşe; 237965; 48566; Uluslararası Ticaret ve Finansman
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.
Defining and Measuring Informality: The Case of Turkish Labor Market1
(2015) Acar, Elif Öznur; Tansel, Aysıt; 48566; Uluslararası Ticaret ve Finansman
In this study, we consider how informality can be defined and measured in the Turkish labor market. The empirical analysis consists of developing three alternative definitions of labor informality, and exploring the relevance and implications of each for the Turkish labor market using descriptive statistics and multivariate probit analysis of the likelihood of informality under each definition. We find that social security registration criterion is a better measure of informality in the Turkish labor market given its ability to capture key relationships between several individual and employment characteristics and the likelihood of informality.
Determination of the Best Simple Moving Average By Stochastic Processes
(2017) İlalan, Deniz; Bankacılık ve Finans
In this study, we consider one of the most popular technical indicators and try to determine the best fitting simple moving average to a given data. Here we utilize from a general mean reverting stochastic process where the mean is time dependent. We propose an identification algorithm which mainly concentrates on the normality of the residual terms after the data is demeaned from simple moving average and also provide evidence that our algorithm works quite well for determination of the “best” simple moving average.
Do Derivative Instruments Play a Role in Performance Theory? The Turkish Closed-End Funds Case
(2016) Pirgaip, Burak; 252136; Bankacılık ve Finans
Market prices of closed-end funds (CEF) deviate from their net asset values (NAV) which is known as “CEF puzzle”. I attempt to show from the Turkish experience that CEF discounts/premia predict the corresponding CEF‟s future returns, in the light of managerial performance theory. But derivatives facet of the subject matter has not been uncovered so far. Therefore I hypothesize that performance of derivative user CEF are better estimators for discounts/premia than non-users. I show a significant positive relation between CEF discounts/premia and future NAV performance. However, this relation seems not to be more explicit for derivative user CEF than non-users

Exchange Rate Volatility and Trade: External Exchange Rate Volatility Matters
(World Scientific Publ Co Pte Ltd, 2020) Tunc, Cengiz; Solakoğlu, Mehmet Nihat; Babuscu, Senol; Hazar, Adalet; Solakoglu, M. Nihat; 161529; Yönetim Bilişim Sistemleri
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.

How globalization affects the operational efficiency of emerging market firms?: A comparative analysis on Turkish SMEs
(Univ Oviedo, 2018) Akdogan, Ece Ceylan; Akdoğan, Ece Ceylan; 17735; Bankacılık ve Finans
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.

Managing working capital efficiency in Turkish agribusinesses and the impact of globalization: insights from an emerging market
(Wageningen Academic Publishers, 2019) Akdogan, Ece C.; Akdoğan, Ece Ceylan; Dinc, Dilek Temiz; 52039; Bankacılık ve Finans
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) Yildiz, Yilmaz; Pirgaip, Burak; Karan, Mehmet Baha; Pirgaip, Burak; 252136; Bankacılık ve Finans
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.

Non-linear unit root testing with arctangent trend: Simulation and applications in finance
(Taylor & Francis As, 2018) Ilalan, Deniz; İlalan, Deniz; Ozel, Ozgur; 234617; Bankacılık ve Finans
We consider arctangent as the logistic function and compute the asymptotic critical values of the related non-linear unit root test via Monte Carlo simulation. While doing so, we got inspiration from some pioneering articles and use first-order Taylor approximation. We observe that this newly proposed test exhibits higher power than some well-known linear and non-linear tests. We apply our test to some stock indexes and find out that a non-linear arctangent trend can be at stage, rather than a linear unit root process.

Profitability effects of financial globalization in an emerging market banking industry: insights into Turkey
(Univ Rijeka, Fac Ecomomics, 2019) Akdogan, Ece C.; Akdoğan, Ece Ceylan; Ozsuca, Ekin Ayse; 237965; Bankacılık ve Finans
The massive ,financial liberalization followed by accelerating financial globalization leaded to significant structural changes in the financial sector: Since financial institutions play a dominant role in functioning of financial sector, especially in emerging markets where banking industries are generally among the most sensitive sectors to increased interconnectedness of financial markets, haw financial globalization actually affects the efficiency of financial intermediation is a vital question. However; although there exists plenty of research focusing on financial integration, impacts of financial globalization is untouched. Hence, this study investigates the bank profitability effects of financial globalization through focusing on an emerging market, Turkey and searches for any potential differences that may prevail among banks with different ownership structures. The findings indicate that while the market based profitability measures improve with financial globalization, the accounting based measures deteriorate pinpointing to an over optimism in the market which in turn brings in mispricing problems. Besides, ownership structure is found to affect the market based measures where banks with domestic and private ownerships are found to benefit more. However; since no significant distinction could be detected among any of the ownership compositions for accounting based profitability measures, such misappraisals seem to foster the optimism in the market.

Testing for Unit Roots in Nonlinear Dynamic Heterogeneous Panels with Logistic Smooth Breaks
(Mdpi, 2023) Omay, Tolga; Omay, Tolga; Ucar, Nuri; Uçar, Nuri; 189073; Çankaya Meslek Yüksekokulu; Bankacılık ve Finans
In this study, we investigate the validity of the purchasing power parity (PPP) proposition for 34 European and selected global countries. For this purpose, we propose a new unit root test for cross-sectionally dependent heterogeneous panels that allows for gradual structural breaks and symmetric nonlinear adjustment toward the equilibrium level. The alternative hypothesis stationary is obtained by symmetric adjustment due to exponential smooth transition autoregression (ESTAR) around a nonlinear trend. Moreover, we provide small sample properties extensively for the newly proposed test. Hence, this alternative hypothesis has been proven to characterize real exchange rate data (REER) correctly. Thus, the newly proposed tests provide an essential basis for modeling the REER series correctly. Finally, we also derive the approximate asymptotic distribution of the proposed tests using new techniques.

The formal/informal employment earnings gap: evidence from Turkey
(Emerald Group Publishing Ltd, 2016) Tansel, Aysit; Acar, Elif Öznur; Acar, Elif Oznur; 48566; Uluslararası Ticaret ve Finansman
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.
