We investigate, using a unique setting from Turkey, whether the market reaction speeds in less sophisticated markets are on par with those of developed markets. We find that market reaction times to corporate announcements are slower than documented in recent studies, although markets react to positive news more quickly than negative news. When high-frequency traders are more active in the market prior to announcements, the speed of price adjustment is slower. Finally, we find sizable profit opportunities for investors following event-driven strategies.Article Citation Count: 1A Max–min Model of Random Variables in Bivariate Random Sequences(Elsevier, 2021) Bayramoğlu, Ismihan; Gebizlioğlu, Ömer LütfiWe introduce a max–min model to bivariate random sequences and applying bivariate binomial distribution in fourfold scheme derive the distributions of associated order statistics in a new model. Some examples for special cases are presented and applications of the results in reliability analysis and actuarial sciences are discussed.Article Citation Count: 29Bank Credit in Uncertain Times: Islamic Vs. Conventional Banks(Elsevier Ltd, 2020) Bilgin, Mehmet Hüseyin; Danışman, Gamze Öztürk; Demir, Ender; Tarazi, AmineThis paper explores whether the impact of economic uncertainty on credit growth differs for Islamic vs. conventional banks. Using a sample of 416 banks (58 Islamic and 358 conventional) in 12 countries, the findings indicate that an increase in economic uncertainty significantly decreases the credit growth of conventional banks but does not have any significant impact on Islamic banks’ credit growth. Our results are robust to alternative specifications and addressing endogeneity concerns using GMM estimators. We further observe that our findings are stronger for the following countries: (1) countries with explicit deposit insurance protection system for Islamic banks, (2) lower foreign dominance, and (3) countries with a higher share of deposits and assets in Islamic banks.Article Citation Count: 44Economic Policy Uncertainty and Bank Credit Growth: Evidence From European Banks(Elsevier B.V., 2020) Danışman, Gamze Öztürk; Ersan, Oğuz; Demir, EnderUsing a sample of 2977 private and listed banks in the EU-5 countries (the United Kingdom, Germany, Spain, Italy, France) for the years 2009–2018, this paper explores the impact of Economic Policy Uncertainty (EPU) on credit growth. Using panel data fixed effects methodology and controlling for endogeneity using two-step difference GMM estimators, our findings indicate that uncertainty in economic policies hampers the credit growth of European banks. Our bank type-based analyses indicate that the effect is mainly valid for cooperative banks. Additional analyses imply that the negative impact of EPU on credit growth is more pronounced in civil law countries, increases with debt maturity, and weakens for banks with a larger number of employees and branches. Furthermore, the unfavorable effects are stronger in well-capitalized banks, banks with foreign subsidiaries, and banks with a higher share of wholesale funding. We also provide several policy implications for different economic actors.Article Citation Count: 5Perceived Financial Needs, Income Sources, and Subjective Financial Well-Being in an Emerging Market(Springer Publishing Co, 2019) Kiymaza, Halil; Öztürkkal, BelmaThis study investigates perceived financial needs and subjective financial well-being using data from a national survey of 2,567 households in Turkey. Financial needs are measured by consumer perceived ability to meet current living expenses in the short-term as well as their assessment for the retirement security in the long-term. We also investigate how income sources are related to subjective financial well-being. Findings show that households' daily concerns including the inability to meet short-term expenses including healthcare, daily living expenses (food and utilities), and the inability to maintain the existing living standard are highly significant factors in explaining their subjective financial well-being. We also find that having enough income during retirement and ability to find a job in the future are positively related to subjective financial well-being. Finally, when households ' incomes are from work, rental properties, family, and pension, they feel more financially secure.Article Citation Count: 7Does Financial Flexibility Enhance Firm Value? a Comparative Study Between Developed and Emerging Countries(VGTU, 2020) Bilyay Erdoğan, SedaThis paper investigates the effect of financial flexibility on firm value, on a comparative basis between developed and emerging countries in Europe. Our dataset covers 4,334 companies from 15 developed and 1,436 companies from 6 emerging countries in Europe for the period between 2000 and 2016. First, depending on companies’ maintenance of leverage that is below-predicted levels for a successive number of years, I identify the financially flexible companies in the sample. Second, I examine whether financial flexibility affects firm value. Our results demonstrate that firms’ financial flexibility positively contributes to firm value in all estimations. Furthermore, this study presents unprecedented evidence that the effect of financial flexibility on firm value is more significant for emerging countries when compared to developed countries in Europe. Moreover, I demonstrate for the first time that firm characteristics, including firm size and age, which proxy for asymmetric information within a company, negatively moderate the relationship between flexibility and firm value. Managers, both in developed and in emerging countries, who aim to surge their firm value up, should give importance to the maintenance of financial flexibility in their capital structure decisions. Last, managers of relatively smaller and younger companies should put more emphasis on becoming financially flexible if they want to improve their firms’ value.Article Citation Count: 5Art Investment: Hedging or Safe Haven Through Financial Crises(Springer, 2020) Öztürkkal, Belma; Toğan-Eğrican, AslıWe analyze long-term art auction sales data focusing on and around financial crisis periods with other investment returns to understand whether art can be considered a safe haven during volatile times or a hedging option in general by analyzing art auction data in a volatile emerging market. Our findings suggest Turkish art returns are either negatively correlated or at low correlation with other investments, including the equity market. We have the view that art can be considered a hedging mechanism on average to enhance returns and to decrease the risk of portfolios and improve diversification. However, we do not discard the safe-haven hypothesis, either. Although the auction data on the crisis period is limited, results of and around crisis periods show art returns are positively correlated with various volatility indices. In addition, the number of art transactions also increases after the crisis years, which may be a sign of liquidity requirement of some investors and an opportunity for buyers. The benefit is visible especially during years of contractions, which do not end with a very severe crisis, since the art auction market liquidity dries if the crisis is severe.Article Citation Count: 1Productivity Analysis of Black Sea Container Ports by Using Integrated Entropy and Eatwos Methods(Eskısehır Osmangazı Univ, 2019) Görçün, Ömer FarukThe Black Sea region is an extremely important region for global trade. Approaches such as short sea shipping and marine highways, which are on the agenda of European Union lead to increase the importance of Black Sea container ports by day by. Thus, performance of seaports of the region will be important factors, which can affect to their development and improvement that will be happened. Because effectivity of seaports may be effected by many factors, it is needed to use the MCDM methodologies can provide a systematic and structural solution way for evaluation. In this study, a hybrid model, which integrated the entropy and EATWOS methods is proposed to make productivity analysis of Black sea container ports. It is expected that obtained results from this study may have a usable characteristic by investors and public authorities in addition to actors, that placed in the logistics processesArticle Citation Count: 8Does mood affect institutional herding?(Elsevier, 2020) Gavriilidis, Konstantinos; Kallinterakis, Vasileios; Öztürkkal, BelmaDrawing on a unique data set of daily portfolio holdings for Turkish mutual funds we investigate the relationship between mood and institutional herding on the premises of various established mood proxies (weekend effect; holiday effect; Ramadan; sunshine). Results indicate that fund managers in Turkey herd significantly, with their herding growing in magnitude as the number of active funds per stock rises and appearing stronger on the buy-than the sell-side. Although the relationship of mood with institutional herding occasionally assumes the correct sign as per theoretical expectations, institutional herding is found to be insignificantly different across various mood states, thus denoting that mood does not impact the propensity of fund managers to herd.

According to new Keynesian school, market clearing mechanism does not exist due to rigidities and stickiness. This situation leads involuntary unemployment. In new Keynesian theory, there are three theories to explain wage rigidities and involuntary unemployment. This paper analyzes these theories in detail and discusses the new Keynesian assumptions from the perspective of Turkish labor market.Article Citation Count: 62Economic Policy Uncertainty, Stakeholder Engagement, and Environmental, Social, and Governance Practices: the Moderating Effect of Competition(Wiley, 2020) Vural-Yavaş, Çiğdemhis paper investigates the effect of the economic policy uncertainty (EPU) on corporate environmental, social, and governance practices (ESG), using 6,562 firm-year observations from 15 developed European countries covering the period from 2004 to 2017. The results show that during periods of high uncertainty, firms increase their overall ESG performance, corporate environmental performance, and performance in governance. The relationship is valid for emission, resource use, workforce, management, and corporate social responsibility (CSR) strategy subdimensions of ESG. Furthermore, during periods of high uncertainty, firms operating in concentrated industries increase their overall ESG activities and corporate environmental performance. These results suggest that firms use ESG practices as risk-reducing activities like insurance, during high periods of uncertainty. Overall, consistent with the stakeholder theory, the results indicate that firms increase their ESG practices not only to reduce corporate risk-taking but also to follow value-increasing activities during periods of high uncertainty, implying an improved stakeholder engagement.Article Citation Count: 3Information Cascades, Short-Selling Constraints, and Herding in Equity Markets(Borsa İstanbul Anonim Şirketi, 2020) Tiniç, Murat; Iqbal, Muhammad Sabeeh; Mahmud, Syed F.This paper examines the relationship between informed trading and herding in Borsa İstanbul. Our firm-level cross-sectional analysis asserts that informed trading can significantly increase future herding levels. Furthermore, we show that the relationship between informed trading and herding intensifies under short-selling restrictions. Our results confirm the predictions of the informational cascades framework where the individuals disregard their private information to follow others. We show that information cascades are relevant both for buy-side herding and sell-side herding. Short-selling restrictions may reinforce the herding behaviour since informed investors may not be able to clear out potential price misalignments.Article Citation Count: 10Efficiency Analysis of Black Sea Container Seaports: Application of an Integrated Mcdm Approach(Routledge, 2020) Ömer Faruk, GörçünThe current paper carries out an examination about the selection of the proper container seaport, which in the Black sea region. This paper focuses on a research question. Is it possible to apply multi-criteria decision-making methods that can be applied more easily than the DEA technique for decision-makers? In order to determine the best performance analysis technique that can give successful results, two-hybrid multi-criteria decision-making models were selected and operational performances of the container ports in the Black Sea region were analyzed with the help of these integrated approaches. While the first MCDM model consists of the entropy and OCRA technique, the second hybrid model consists of the Entropy and EATWIOS method. The main aim of this paper is to discuss whether these proposed hybrid models can be implemented to make an effective performance analysis for the maritime industry. The second aim of this paper is to evaluate the Black sea container seaports with the help of this suggested model. The study reveals that the proposed MCDM models can be implemented for container port selection successfully and easily and both of them have given very closer results to each other in aspects of the evaluation of the criteria and options.Article Citation Count: 2Informed Trading, Order Flow Shocks and the Cross Section of Expected Returns in Borsa Istanbul(Routledge Journals, 2020) Tiniç, Murat; Salih, AslihanThis paper examines the relationship between information asymmetry and stock returns in Borsa Istanbul. For all stocks that are traded in Borsa Istanbul between March 2005 and April 2017, we estimate the probability of informed trading (PIN) to proxy for information asymmetry.? Firm-level cross-sectional regressions indicate a statistically insignificant relationship between PIN estimates and future returns. Moreover, univariate and multivariate portfolio analyses assert that investors that hold stocks that have high information asymmetry do not obtain significant future returns. Consequently, our results suggest that information asymmetry proxied by PIN is a firm-specific risk and can be eliminated with portfolio diversification. Findings are robust to different factorizations in estimating PIN and free of any bias due to trade classification algorithms, boundary solutions, floating-point exceptions and symmetric?order flow shocks.Article Citation Count: 4Political Turmoil and the Impact of Foreign Orders on Equity Prices(Elsevier, 2020) Tiniç, Murat; Savaşer, TanseliThis paper examines whether foreign investors possess an information advantage over local investors in the Turkish stock market between 2007 and 2015. We find that foreign investors have an information advantage in 24 stocks, corresponding to seven percent of the sample firms. Foreign investors' information advantage tends to prevail primarily during a period of political instability, which started with the Gezi Park protests in June 2013. The adverse selection component of the foreign trade spreads, which reflects a permanent change in stock prices, rises significantly after June 2013, by 66 bps. Our results suggest that domestic investors' funding constraints, which limit their ability to impart their information on stock prices, may give foreign investors a relative information advantage during periods of political turmoil.

It focuses on how people’s religious and political characteristics impact the independence of their decision making regarding saving and borrowing. An earlier study by Davutyan and Ozturkkal (2016) reports saving and borrowing decisions strongly correlate with income, education, marital status and region within country. Furthermore, 54% of those surveyed did not save and the main motivation for those who saved was to finance children’s education or home purchase. Religious people and those with a conservative lifestyle are less likely to borrow from family and friends. Older, married and working individuals are more likely to have difficulty paying back loans. According to the results of this survey, religious individuals are less likely to independently decide on their investment choices. Thus, religious people tend to make investment decisions together with family, elderly and respected relatives.Article Citation Count: 1The Maximum Surplus in a Finite-Time Interval for a Discrete-Time Risk Model With Exchangeable Dependent Claim Occurrences(John Wiley and Sons Ltd, 2019) Gebizlioğlu, Ömer Lütfi; Eryilmaz, SerkanThis paper investigates a discrete-time risk model that involves exchangeable dependent loss generating claim occurrences and compound binomially distributed aggregate loss amounts. First a general framework is presented to derive the distribution of a surplus sequence using the model. This framework is then applied to obtain the distribution of any function of a surplus sequence in a finite-time interval. Specifically the distribution of the maximum surplus is obtained under nonruin conditions. Based on this distribution the computation of the minimum surplus distribution is given. Asset and risk management–oriented implications are discussed for the obtained distributions based on numerical evaluations. In addition comparisons are made involving the corresponding results of the classical discrete-time compound binomial risk model for which claim occurrences are independent and identically distributed. © 2018 John Wiley & Sons Ltd.Article Citation Count: 8An Analysis of the Unemployment Selected Mena Countries and Turkey(2008) Bilgin, Mehmet Hüseyin; Kilicarslan, Ismihan N, I. N.One of the most important economic and social problems of the Middle East and North Africa (MENA) is the high rate of unemployment. Unemployment in the selected MENA countries like Egypt Israel Jordan and Turkey are examined as well as the relationship between growth and unemployment. For this reason active labor market policies should be designed to address job creation in addition to structural reform in labor markets.
