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.

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.

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) Akdoğan, Ece Ceylan; 17735; 03.01. Bankacılık ve Finans; 03. İktisadi ve İdari Birimler Fakültesi; 01. Çankaya Üniversitesi
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.
