Art Investment: Hedging or Safe Haven Through Financial Crises
(Springer, 2020) Öztürkkal, Belma; Toğan-Eğrican, Aslı
We 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.

A Behavioral Analysis of Investor Diversification
(Routledge Journals Taylor & Francis Ltd, 2014) Fuertes, Ana-Maria; Muradoğlu, Gülnur; Öztürkkal, Belma
This paper studies the link between individual investors' portfolio diversification levels and various personal traits that proxy informational advantages and overconfidence. The analysis is based on objective data from the largest Turkish brokerage house tracking 59951 individual investors' accounts with a total of 3248654 million transactions over the period 2008-2010. Wealthier highly educated older investors working in the finance sector and those trading relatively often show higher diversification levels possibly because they are better equipped to obtain and process information. Finance professionals married investors and those placing high-volume orders through investment centers show poorer diversification possibly as a reflection of overconfidence. Our analysis reveals important nonlinear effects implying that the marginal impact of overconfidence on diversification is not uniform across investors but varies according to the investor's information gathering and processing abilities.

Competition in Turkish Banking: Impacts of Restructuring and the Global Financial Crisis
(Wiley, 2014) Yıldırım, Canan
This paper investigates the evolution of competition in the Turkish banking industry by taking into account the transformation in the sector in the aftermath of the country's financial crisis of 2000 to 2001 and the global financial crisis. The results demonstrate that the level of competition in the system did not increase despite the restructuring that was undertaken and the increased foreign bank participation. In addition the level of competition in the sector deteriorated during the global crisis. There is also some evidence that the market power of banks with different ownership characteristics varied and did not converge over time.

Efficiency Analysis of Black Sea Container Seaports: Application of an Integrated Mcdm Approach
(Routledge, 2020) Ömer Faruk, Görçün
The 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.

Efficiency in Turkish Banking: Post-Restructuring Evidence
(Routledge Journals Taylor & Francis Ltd, 2017) Davutyan, Nurhan; Yıldırım, Canan
Turkish banking sector went through a significant restructuring process in the aftermath of the country's financial crisis of 2000-2001. In this paper we analyze the evolution of banking performance using a novel approach due to Ray [(2007). Shadow Profit Maximization and a Measure of Overall Inefficiency. Journal of Productivity Analysis 27 231-236]. We derive shadow unrealized profit scores' as well as shadow input-output prices' for each year and bank in the sector from 2002 to 2011. We argue these scores operationalize the Hicksian concept of monopolistic quiet life'. We provide some evidence the sector came closer to the zero profit condition' as well as displaying a closer approximation to the law of one price' over time. We show the variability of these shadow prices' essentially coincides with that of corresponding actual prices. We utilize shadow price information to show that business models and competitive choices of banks differ across ownership types with foreign banks competing on the broadest front compared to state-owned and privately owned Turkish banks.

Informed Trading, Order Flow Shocks and the Cross Section of Expected Returns in Borsa Istanbul
(Routledge Journals, 2020) Tiniç, Murat; Salih, Aslihan
This 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.

The 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, Serkan
This 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.

Perceived Financial Needs, Income Sources, and Subjective Financial Well-Being in an Emerging Market
(Springer Publishing Co, 2019) Kiymaza, Halil; Öztürkkal, Belma
This 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.

Who Was Colonized and When? a Cross-Country Analysis of Determinants
(Elsevier Science Bv, 2016) Ertan, Sabri Arhan; Fiszbein, Martin; Futterman, Louis
The process of colonization has shaped the economic and demographic contours of the modern world. In this paper we study the determinants of the occurrence and timing of colonization of non-European countries by Western European powers. Of particular interest is the role of early development measures that are known to be strong correlates of present-day levels of income. We show that non-European societies with longer histories of agriculture and statehood and higher levels of technology adoption in 1500 were less likely to be colonized and tended to be colonized later if at all. We also find that proximity to the colonizing powers disease environment and latitude are significant predictors of the occurrence and timing of colonization although their impacts are less robust to choice of country sample. Our models have high explanatory power and their support for the significance of early development is robust to the use of alternative indicators of early development and disease to the use of instruments to focus on the exogenous component of early development and to the joint estimation of the colonization and timing equations to correct for potential selection bias.
