    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.

    Fractional Frequency Flexible Fourier Form To Approximate Smooth Breaks in Unit Root Testing
    (Elsevier Science Sa, 2015) Omay, Tolga; 19320; 08.02. Çankaya Meslek Yüksekokulu; 08. Meslek Yüksekokulları; 01. Çankaya Üniversitesi
    In this study, a Fractional Frequency Flexible Fourier Form DF-type unit root test is proposed. The small sample properties of the proposed test are found to be better than that of the integer frequency counterpart. (C) 2015 Elsevier B.V. All rights reserved.

    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.
