Can Stock Price Manipulation be Prevented by Granting More Freedom to Manipulators
(2015) İlalan, Deniz
Allen 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.
An examination of the major behavioral aspects of distribution channels in an export channel design
(2012) Karadağlı, Ece; Aluftekin, Nilay
This 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.
Asymmetric Smooth Transition in Cds Spreads: Evidence From Latvia
(Allied Business Academies, 2019) Akdoğan, E.C.; Akdoğan, Ece Ceylan; Bankacılık ve Finans
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.

A Poisson Process With Random Intensity for Modeling Financial Stability
(Ediciones Doyma, S.L., 2016) Ilalan, D.
Stock 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 Finanzas
How Globalization Affects The Operational Efficiency of Emerging Market Firms?: A Comparative Analysis On Turkish SMEs
(Univ Oviedo, 2018) Akdoğan, Ece Ceylan
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.
Overview of Financial Reporting in the Airline Industry
(Emerald Group Publishing Ltd, 2022) Ozturk, Can
This chapter focuses on the diversity of financial reporting frameworks in the airline industry considering past and present. While diversity of financial reporting frameworks existed in the past, currently, the majority of listed and non-listed airlines, whose financial statements are publicly available, are inclined to adopt International Financial Reporting Standards (IFRS), leading toward uniformity in financial reporting frameworks because their country of incorporation or the stock exchange where they are listed either require or permit them to do so. Airlines operating in the United States prepare their financial statements under United States Generally Accepted Accounting Principles and some of Asian-Pacific countries still use their own national accounting standards in financial reporting. In addition, this research points out that the primary determinant of IFRS adoption in the airline industry is the fact that the majority of airlines are listed in national or foreign stock exchanges where IFRS adoption is required, but there are some company-specific determinants for listed and non-listed IFRS adopting airlines. Finally, this chapter also sets forth that there are jurisdictional versions of IFRS in the global context from the perspective of financial statements of airlines leading to some obstacles in understanding the financial reporting framework.
Perspectives on the Preparation and Presentation of a Statement of Cash Flows Under Ias 7: an Historical Approach
(Springer Nature, 2023) Baker, C.R.; Öztürk, C.
This chapter provides perspectives on the preparation and presentation of the statement of cash flows under IAS 7 of the International Financial Reporting Standards by adopting an historical approach. It focuses on the transformation attempts of the statement of cash flows along with the influence of such attempts on the statement of financial position. It analyzes and discusses the proposed changes on this statement offered through (1) the Discussion Paper on preliminary views on Financial Statement Presentation that was published by the International Accounting Standards Board (IASB) in 2008 right after the compliance of IAS 1 (2007) Presentation of Financial Statements to other comprehensive income items, (2) the staff draft of Exposure Draft IFRS X Financial Statement Presentation that was issued by the staff of the IASB in 2010, (3) Exposure Draft ED/2012/1 Annual Improvements to IFRSs 2010–2012 Cycle that was published by the IASB in 2012, (4) staff Discussion Paper of the United Kingdom’s Financial Reporting Council that was published in 2016, and (5) the Exposure Draft ED/2019/7 General Presentation and Disclosure that was issued by the IASB in 2019 toward the objective of improved financial communication. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Profitability Effects of Cash Conversion Cycle: Evidence From Turkish Companies
(National Academy of Management, 2013) Karadagli, E.
This paper examines the impact of cash conversion cycle and its single components, specifically accounts collection period, inventory turnover in days and accounts payable period, on firm profitability as measured by operating income and stock market return by using pooled panel analysis for the period of 2001-2010. Besides, the possible effects of group affiliation on the impact of CCC and its components on firm profitability are also investigated. The findings suggest that shortening of CCC and its single components, including accounts payable period, improve firm profitability in terms of both accounting and market measures of performance. The findings also indicate that both the affiliated and the unaffiliated firms can enhance firm performance in terms of both performance measures through shortening their CCCs, this effect is stronger for unaffiliated firms and hence working capital management seems to be more important for them. © Ece Karadagli, 2013.

Elliott Wave Principle and the Corresponding Fractional Brownian Motion in Stock Markets: Evidence From Nikkei 225 Index
(Pergamon-elsevier Science Ltd, 2016) Ilalan, Deniz
This 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. All rights reserved.

The Impact of Fed Policy Announcements on Emerging Stock Markets: Evidence from Borsa Istanbul
(2017) Akdoğan, Ece C.; İlalan, Deniz
This paper aims to understand the impact of US nonfarm payroll announcements on emerging stock markets through concentrating on the Turkish Stock Exchange: BIST 100. We not only investigate the impact of each of the three components of the nonfarm payroll data for the whole period under consideration, but also look for possible differences among four sub-periods. A comparative analysis leads us to conclude that it is not the nonfarm payroll which significantly affect BIST 100, but the fact that it is regarded as an important indicator to foresee Fed’s policy actions that can alter the capital flows.

Reexamining the Ppp Hypothesis: a Nonlinear Asymmetric Heterogeneous Panel Unit Root Test
(Elsevier, 2014) Omay, Tolga; Emirmahmutoglu, Furkan
In this study, we re-examine the PPP hypothesis in the light of the new developments in the unit root testing literature. The recent theoretical findings have pointed out that the real exchange rate series exhibit asymmetric nonlinear behavior. A unit root test applied to analyze the PPP hypothesis therefore, should also take into account this asymmetry inherent in the real exchange rate. Different unit root tests that consider the presence of these data features have been developed in the time series literature. However, a true attempt to test the PPP hypothesis should take a panel data approach. To this end, we propose a nonlinear heterogeneous panel unit root test where the alternative hypothesis allows for symmetric or asymmetric exponential smooth transition autoregressive nonlinearity and provide its finite sample properties. We apply our test to the real exchange rates of the 15 European Union countries against the US dollar. While the results of the linear and symmetric nonlinear heterogeneous panel unit root tests are against the PPP hypothesis, the asymmetric nonlinear heterogeneous panel test that we propose gives support for the PPP hypothesis as expected. Therefore, the conclusions drawn from the linear panel unit root tests or the nonlinear panel unit root tests that do not take asymmetry into account might be misleading. (C) 2014 Elsevier B.V.

Unit Root Testing in the Presence of Mean Reverting Jumps: Evidence From US T-Bond Yields
(Walter de Gruyter GmbH, 2019) Ilalan, Deniz; Ozel, Ozgur
Mean reversion of financial data, especially interest rates is often tested by linear unit root tests. However, there are times where linear unit root test results can be misleading especially when mean reverting jump formations are at stage. Considering this framework, we provide a new unit root testing methodology and compute its asymptotic critical values via Monte Carlo simulation. Moreover, we numerically compare the power of this generalized mean reversion test with the pioneering linear unit root test in the literature namely the Augmented Dickey Fuller (ADF) test. We deduce that our test is a refinement of ADF test with a higher power. Weapply our findings to US 10-year Treasury bond yields. We aim to shed light to the discussion among researchers whether interest rates can sometimes revert to a long-term constant mean or not from an unorthodox point of view.

The Stock and Cds Market Consequences of Political Uncertainty: The Arab Spring
(Routledge Journals, Taylor & Francis Ltd, 2022) Savaser, Tanseli; Usul, Naime; Tanyeri, Basak
We investigate how political unrest affects asset prices in the context of the Arab Spring. Abnormal returns in the major stock-market indices of Arab Spring countries average -1.1% on key days of Arab Spring and abnormal changes in credit default spreads average 1.4%. There is significant reaction to region wide as well as local protests indicating a spillover with protests in neighboring countries affecting investors' perception of local political instability and the pricing of assets. Once protests start locally, investors start paying more attention to what is happening at home than in the region. The significant stock market reaction to region-wide protests in Arab Spring countries indicates a spill-over where investors price an increase in the probability of political turmoil in one country when there are protests in neighboring countries. The decline in stock market indices coupled with the increase in credit default spreads indicates that investors anticipate and ex-ante price how current political uncertainty will affect firm value.

An Empirical Analysis of Household Education Expenditures in Turkey
(Pergamon-elsevier Science Ltd, 2016) Cilasun, Seyit Mumin; Acar, Elif Oznur; Gunalp, Burak
Using 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.

The Causal Relationship Between Stock Markets and Policy Uncertainty in Oecd Countries
(Bc Grup inc, 2017) Pirgaip, Burak
In this study, we examine the causal relationship between economic policy uncertainty (EPU) and stock market prices in OECD countries. We provide strong evidence that stock markets mostly Granger cause EPU. Such causality may also exist in the opposite direction for a few cases and we find no causality in some countries as well. Our results do not provide any support for bidirectional causality.
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, Tolga
This 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.
Sector-Level Competition and Export: Evidence From Exporter Dynamics Database
(World Scientific Publ Co Pte Ltd, 2019) Hazar, Adalet; Solakoglu, M. Nihat; Tunc, Cengiz; Babuscu, Senol
We study the effect of sector-level competition on export by utilizing the Exporter Dynamics Database of the World Bank that provides sector-level competition measure along with destination-specific detailed export data. The results of the analysis show a nonlinear effect of sector-level competition on export. While at less competitive sectors, an increase in competition depresses export, at highly competitive sectors, an increase in competition generates a trade-promoting effect on export. The observed nonlinear effect is robust across sectors and countries. Therefore, productivity of peer firms could generate negative effect on a firm's export performance contrary to the usual positive effect of a firm's own productivity.
Corporate Diversification and Internal Capital Markets: Evidence from the Turkish Business Groups
(2004) Gönenç, Halit; Kan, Özgür Berk; Karadağlı, Ece C.
We 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.
