Accordingly, this paper examines weak form futures market efficiency of five CEE Emerging Economies. For this purpose, besides the traditional unit root tests, to account for nonlinearities in financial data, we employ nonlinear unit root tests along with their panel extensions. The results suggest that although the examined markets are efficient in linear sense, inefficiencies prevail when we account for nonlinearities. These findings imply that the examined countries, especially Poland and Turkey, need to take precautions to overcome the obstacles in their prevailing market structures, especially inherited in the sources of nonlinearity in the financial data, and to ensure a more efficient futures marketsArticle Citation Count: İlalan, Deniz (2016). "A Poisson process with random intensity for modeling financial stability", Spanish Review of Financial Economics, Vol. 14, No. 2, pp. 43-50.A Poisson process with random intensity for modeling financial stability(2016) İlalan, DenizStock market crashes are hazardous for financial stability and usually modeled via Poisson processes having a predetermined fixed intensity. This study uses a more general framework by allowing the intensity to be random in order to model rare events called the “unpredictable unknowns”. Three stock indices, namely Japan Nikkei 225, US Dow Jones Industrial Average and Turkish BIST 100 are analyzed. Simulation results indicate that in stable markets, we encounter fewer unpredictable unknowns compared to unstable ones. However, it is also shown that stable markets are more prone to severe financial crises. © 2015 Asociación Española de FinanzasArticle Citation Count: Acar, Elif Oznur; Gunalp, Burak; Cilasun, Seyit Mumin, "An empirical analysis of household education expenditures in Turkey", International Journal of Educational Development, Vol. 51, pp. 23-35, (2016).An empirical analysis of household education expenditures in Turkey(Pergamon-Elsevier Science LTD, 2016) Acar, Elif Öznur; Günalp, Burak; Cilasun, Seyit MüminUsing 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.

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.

"An Examination Of The Effects Of The February, 2001 Crisis (Turkey) On The Performances Of The Low-Q And High-Q Firms", International Business & Economics Research Journal, Vol.5, No.7, pp.41-44.An Examination Of The Effects Of The February, 2001 Crisis (Turkey) On The Performances Of The Low-Q And High-Q Firms(2006) Karadağlı, Ece C.; Omay, TolgaThis paper examines the effects of the February 2001 Economic Crisis (Turkey) on the low-Q and high-Q firms. In the study, our sample is composed of the firms that are actively being traded on Istanbul Stock Exchange (ISE) during that time, and is divided into two sub-samples based on their Tobins' Q values. As firms with high Tobins' Q values are supposed to have lower debt levels we proposed them to be less affected by the crises: their debt repayment commitments are lower, although they are expected to be under the burden of higher interest rates. On the other hand, low-Q firms have incentives to overinvest due to the high levels of available free cash and they may be under the burden of some perquisites expenses. But because of the asset substitution affect, the investments undertaken by low-Q firms are expected to be safer projects while high-Q firms may have undertaken more risky projects. To test our hypothesis that the crisis would affect the low-and high-Q firms to differing extends, we construct the average mean excess returns of both sub-samples and use the Large Sample Test of Hypothesis About a Population Mean method. Our results mainly confirm our expectations: we found that the average mean excess negative returns of high-Q firms were higher than that of low-Q firms during the February 2001 Crisis, indicating that high-Q firms are more riskier in an economic crisis setting than low-Q firms, which in turn implies that the effects of the conflict between equityholders and debtholders dominate the affects of the conflict between managers and the shareholders.Article Citation Count: Karadağlı, Ece; Aluftekin, N.

"An examination of the major behavioral aspects of distribution channels in an export channel design", African Journal Of Business Management, Vol.6, No.6, pp.2211-2220.An examination of the major behavioral aspects of distribution channels in an export channel design(2012) Karadağlı, Ece; Aluftekin, NilayThis paper concentrates on the behavioral aspects of distribution channels in an export channel design from the perspective of the exporter. Based on the argument that channel conflict and satisfaction are among the major determinants of channel efficiency and performance, the perceived degrees of channel conflict and satisfaction are examined as well as the three antecedents of channel conflict, namely the channel power, cultural distance and distribution system quality, as they are regarded among major factors affecting the channel conflict. In conducting the analysis, questionnaire survey was undertaken among 30 exporter companies that are members of Ankara Chamber of Commerce and Likert scaling technique is used. The findings from the ordinary least squares (OLS) regression analysis suggest that the Turkish exporter do not regard the level of exercised power in a marketing channel system and the cultural distance between the foreign channel member’ markets as important sources of conflict while the international distribution system quality seems to be perceived as a major source of channel conflict. The findings also suggest that there exists a close relationship between the perceived channel conflict and the channel members’ satisfaction.Article Citation Count: Akdoğan, E.C.,"Asymmetric Smooth Transition in Cds Spreads: Evidence From Latvia",Academy of Accounting and Financial Studies Journal, Vol. 23, No. 3, pp. 7, (2019).Asymmetric Smooth Transition in Cds Spreads: Evidence From Latvia(Allied Business Academies, 2019) Akdoğan, Ece Ceylan; 17735This 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.Article Citation Count: Öztürk, Can. (2015).

"Can Stock Price Manipulation be Prevented by Granting More Freedom to Manipulators", International Journal of Economics and Finance, Vol. 7, No. 3, pp. 179-187.Can Stock Price Manipulation be Prevented by Granting More Freedom to Manipulators(2015) İlalan, DenizAllen and Gale (1992) construct a model to show that stock price manipulation is possible. The time structure of their model allows manipulators to pretend as “informed” traders, so that the local investors cannot distinguish what type of entrant they are facing. When the type of the entrant becomes known to the local investors it is already too late to make any use of that information. This paper shows an institution can be designed in a very natural fashion which induces different behaviors on the part of manipulators and “informed” traders at the beginning of the process. The institution designed roughly consists of entitling the entrants to resell stocks at a later date as well if they wish to do so. As this reasoning is also accessible to manipulators, the designed institution deters them from entering the market. Regarding the informed traders, their expected gain from entering the stock market may or may not be positive contingent on the basic parameters of the model. There are cases, however, when there is an improvement in the expected total gain of the local investors.Book Part Citation Count: Gönenç, Halit; Kan, Ozgur Berk; Karadagli, Ece C., "Corporate Diversification and Internal Capital Markets: Evidence from the Turkish Business Groups", 2004.Corporate Diversification and Internal Capital Markets: Evidence from the Turkish Business Groups(2004) Gönenç, Halit; Kan, Özgür Berk; Karadağlı, Ece C.; 17735We compare the performance of firms affiliated with diversified business groups with the performance of unaffiliated firms in an emerging market, Turkey. Our findings indicate that group affiliation improves firm's accounting performance, but not stock market performance. Furthermore, we find that firm's accounting (but not stock market) performance increases with the level of group diversification. Our results also indicate that having a group affiliated bank affects the accounting performance measures of the group firms positively, but the market value of the group affiliated firms negatively, supporting the misallocation of capital hypothesis. In addition, having a group affiliated media institution is found to affect the performance of the group firms positively. More importantly, we examine the frequency of seasoned equity issue offerings with the forms of cash (right and restricted right) issues and bonus issues to address the question of whether group affiliated firms create an internal capital market. We show that unaffiliated firms are more bound to external markets to raise capital while the affiliated firms use internal capital markets.

"Economic exposure of emerging market firms", Actual Problems of Economics, Vol. 166, No. 4, pp. 67-74.Economic exposure of emerging market firms(2015) Akdoğan, Ece Ceylan; 17735Although 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.Article Citation Count: Ilalan, Deniz, "Elliott wave principle and the corresponding fractional Brownian motion in stock markets: Evidence from Nikkei 225 index", Chaos Solitons & Fractals, Vol. 92, pp. 137-141, (2016).Elliott wave principle and the corresponding fractional Brownian motion in stock markets: Evidence from Nikkei 225 index(Pergamon-Elsevier Science LTD, 2016) İlalan, DenizThis 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.

"ENERGY CONSUMPTION AND GROWTH: NEW EVIDENCE FROM A NON-LINEAR PANEL AND A SAMPLE OF DEVELOPING COUNTRIES", Singapore Economic Review, Vol. 60, No. 2.ENERGY CONSUMPTION AND GROWTH: NEW EVIDENCE FROM A NON-LINEAR PANEL AND A SAMPLE OF DEVELOPING COUNTRIES(2015) Omay, Tolga; Apergis, Nicholas; Özçelebi, HülyaThis 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.Article Citation Count: Tunç, C., Solakoğlu, M.N., Babuşcu, Ş., Hazar, A. (2018). Exchange rate risk and international trade: The role of third country effect. Economics Letters, 167, 152-155. http://dx.doi.org/ 10.1016/j.econlet.2018.03.030Exchange rate risk and international trade: The role of third country effect(Elsevier Science S A, 2018) Tunç, Cengiz; Solakoğlu, Nihat; Babuşcu, Şenol; Hazar, Adalet; 265921; 161529; 117425; 219046Using 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.Article Citation Count: Tunç, Cengiz...et al (2020).

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. © 2020 World Scientific Publishing Company.Article Citation Count: Omay, Tolga (2015).

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.Book Citation Count: Öztürk, Can.
