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.

Profitability Effects of Financial Globalization in an Emerging Market Banking Industry: Insights Into Turkey
(Univ Rijeka, Fac Ecomomics, 2019) Ozsuca, Ekin Ayse; Akdogan, Ece C.
The massive ,financial liberalization followed by accelerating financial globalization leaded to significant structural changes in the financial sector: Since financial institutions play a dominant role in functioning of financial sector, especially in emerging markets where banking industries are generally among the most sensitive sectors to increased interconnectedness of financial markets, haw financial globalization actually affects the efficiency of financial intermediation is a vital question. However; although there exists plenty of research focusing on financial integration, impacts of financial globalization is untouched. Hence, this study investigates the bank profitability effects of financial globalization through focusing on an emerging market, Turkey and searches for any potential differences that may prevail among banks with different ownership structures. The findings indicate that while the market based profitability measures improve with financial globalization, the accounting based measures deteriorate pinpointing to an over optimism in the market which in turn brings in mispricing problems. Besides, ownership structure is found to affect the market based measures where banks with domestic and private ownerships are found to benefit more. However; since no significant distinction could be detected among any of the ownership compositions for accounting based profitability measures, such misappraisals seem to foster the optimism in the market.
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.
Non-Linear Unit Root Testing With Arctangent Trend: Simulation and Applications in Finance
(Taylor & Francis As, 2018) Ozel, Ozgur; Ilalan, Deniz
We consider arctangent as the logistic function and compute the asymptotic critical values of the related non-linear unit root test via Monte Carlo simulation. While doing so, we got inspiration from some pioneering articles and use first-order Taylor approximation. We observe that this newly proposed test exhibits higher power than some well-known linear and non-linear tests. We apply our test to some stock indexes and find out that a non-linear arctangent trend can be at stage, rather than a linear unit root process.

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

An Empirical Examination of the Generalized Fisher Effect Using Cross-Sectional Correlation Robust Tests for Panel Cointegration
(Elsevier Science Bv, 2015) Yuksel, Aydin; Omay, Tolga; Yuksel, Asli
This study examines the generalized Fisher hypothesis as applied to common stocks by using the recently proposed second generation panel cointegration tests. 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. All rights reserved.

Market Reaction To Grouping Equities in Stock Markets: an Empirical Analysis on Borsa Istanbul
(Elsevier, 2017) Karan, Mehmet Baha; Pirgaip, Burak; Yildiz, Yilmaz
The main aim of this study is to investigate the market reaction to stock grouping announcements in Borsa Istanbul which requires stocks to be classified into groups "A ", "B" and "C" according to their market capitalization and floating rates. By utilizing event study analysis, our results suggest that grouping announcements have significant effect on stock prices and trading volume. The event day positive (negative) relationship between abnormal return and volume for the upgraded (downgraded) stocks supports the downward sloping demand curve hypothesis. Moreover, findings also suggest that stocks which are upgraded to Group A are exposed to more attention which is in line with the attention hypothesis. The reverse is valid for the downgraded firms. We find no evidence of price reversals and long-term symmetrical liquidity effect which lead us to reject price pressure and liquidity hypotheses. Finally, we reach controversial evidence for the information hypothesis. Copyright (c) 2017, Borsa Istanbul Anonim Sirketi. Production and hosting by Elsevier B.V.

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.

Exchange Rate Volatility and Trade: External Exchange Rate Volatility Matters
(World Scientific Publ Co Pte Ltd, 2020) Babuscu, Senol; Hazar, Adalet; Solakoglu, M. Nihat; Tunc, Cengiz
We investigate the role of external exchange rate volatility in export in addition to the effect of bilateral exchange rate volatility using country-, sector-, and destination-specific detailed export data of the World Bank Exporter Dynamics Database. 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.
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.

An Alternative Mean Reversion Test for Interest Rates
(Central Bank Republic Turkey, 2018) Ozel, Ozgur; Ilalan, Deniz
A number of empirical studies assert that interest rates are governed by unit root processes rejecting any form of reversion to a long term mean by resorting to certain tests, among which the Augmented Dickey Fuller (ADF) is the most widely used one. In this study, we propose an alternative testing methodology that can be applied along with ADF test, in the sense that there are times where it can capture stationarity when the other fails to do so. Moreover, our test has more power than ADF test. As an application to real-data, we consider 10-year US and Turkish T-bond rates. (C) 2017 Central Bank of The Republic of Turkey.

An Outline of Skilled Emigration from Turkey to OECD Countries: A Panel Data Analysis
(2017) Acar, Elif Öznur
Turkey provides rich evidence for the current international migration trends given its economic and demographic dynamics. The number of people moving overseas to settle permanently has been following an increasing trend in the recent decades, particularly remarkable for skilled and female groups. However, given the micro-level data limitations the migration outlook of Turkey is still quite bleak. The aim of this paper is to fill this gap and analyze the relationship between migration and human capital in the context of Turkish immigrants. First, aggregate trends of the Turkish emigrants in the 20 OECD destination countries by gender and educational level over the 1980-2010 period are examined using the IAB Brain Drain dataset. Next, a random effects panel estimation is applied to scrutinize the underlying dynamics of observed migration patterns adopting economic size, unemployment, demographic profile, urbanization and proximity as explanatory variables. The results reveal that gender, time and education are found as significantly related to international mobility trends, and the substantially left-skewedness of the distribution of Turkish emigrants along educational level is gradually fading away over time.
Do Derivative Instruments Play a Role in Performance Theory? The Turkish Closed-End Funds Case
(2016) Pirgaip, Burak
Market prices of closed-end funds (CEF) deviate from their net asset values (NAV) which is known as “CEF puzzle”. I attempt to show from the Turkish experience that CEF discounts/premia predict the corresponding CEF‟s future returns, in the light of managerial performance theory. But derivatives facet of the subject matter has not been uncovered so far. Therefore I hypothesize that performance of derivative user CEF are better estimators for discounts/premia than non-users. I show a significant positive relation between CEF discounts/premia and future NAV performance. However, this relation seems not to be more explicit for derivative user CEF than non-users
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.

Çalışmanın bulguları şunlardır: 2018-2021 dönemi makaleleri 2016- 2017 dönemine oranla BOBİ FRS’ye genel bakıştan çok BOBİ FRS’nin bölümlerine odaklanmıştır; yazılan makalelerin büyük bir bölümünde Türkiye’deki çoklu muhasebe mevzuatı dikkate alınarak karşılaştırmalı yaklaşım benimsenmiştir ve makalelerin çoğunda örnek uygulamalara yer verilmiştir.
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.
