Comparison of methods for allocation of service departments' costs to operating departments: A Monte Carlo simulation
(ACADEMIC JOURNALS, 2010) Suleyman Yukcu; Hakan Ozkaya; Ozkaya, Hakan; Yukcu, Suleyman
In this paper, the performance of widely used methods for allocation of multiple service departments costs to operating departments namely direct method and two different applications of step-down method were compared by using the criteria of deviation of their results from those of reciprocal method which is posited as the most accurate method for allocation. Moreover the conditions under which each method yielded the best results were presented. Our dataset included randomly obtained 10000 observations with different percentages of service provided by service departments and different cost figures. Results indicated that the application of step-down method which considered percentage of service provided as the base for ranking service departments yielded least deviation from results of reciprocal method on average and yielded the best results with highest probability and the worst results with the least probability thus provided more accurate results than competing methods.

Does Corporate Reputation Improve Stock Performance in an Emerging Economy ? Evidence From Turkey
(PALGRAVE MACMILLAN LTD, 2011) Osman Gok; Hakan Ozkaya; Ozkaya, Hakan; Gok, Osman
Corporate reputation has long been recognized as a valuable asset and several studies have investigated the relationship between reputation and various performance measures. However researchers have reached conflicting results for companies in developed countries indicating positive conditionally positive and even no relationship. This study finds that a portfolio of highly admired firms in an emerging economy earns about 10 percent less than that market's overall portfolio annually and discusses possible explanations for this finding.

Financial Openness and Financial Development: Evidence from Emerging Countries
(ISTANBUL UNIV SCH BUSINESS, 2020) Mehmet Umutlu; Melis Gultekin; Hakan Ozkaya; Ozkaya, Hakan; Umutlu, Mehmet; Gultekin, Melis
We investigate the potential relation between financial openness and financial development for 27 emerging countries for the period between 1996 and 2016. We focus on three dimensions of financial openness: capital account openness trade openness and stock-market openness. In this study we propose alternative measures for capital account and trade openness. Moreover we offer capital flow and valuation-based measures for stock-market openness as a potential determinant of financial development. Our findings indicate that capital account openness and trade openness are the key drivers of financial development. These results are not sensitive to the use of alternative financial openness and financial development measures and are robust after being controlled for institutional quality and its components. Our results have implications for policymakers in emerging countries who try to increase the depth of their financial markets for an easier and cheaper access to funds.
