(Elsevier Science Bv, 2016) Kiymaz, Halil; Kiymaz, Halil; Öztürkkal, Belma; Akkemik, Küçük Ali; Akkemik, K. Ali; Öztürkkal, Ayşe Belma; Economics; International Trade and Finance; Business Administration
This study extends the existing literature on the determinants of behavioral biases of Turkish finance sector professionals. It examines the impact of various personal and objective attributes of finance sector professionals on their risk choices derived from their portfolio allocation and personal wealth data. Utilizing survey data from 206 professionals we find that these professionals take higher risk in the form of investment in equities when investing in home country firms (geographic bias) and investing in firms headquartered in their home towns (home bias). Those relying on their own predictions when making investment decisions and those with emotional biases invest less in equities. Findings further show that younger professionals professional with less education with lower risk aversion and with single broker accounts are more likely to invest in equities. We also find that those with higher expected returns invest more in equities showing overconfidence. Subsample analysis results for finance professionals suggest that portfolio managers and brokerage company professionals display differing risk taking behavior. (C) 2016 Elsevier B.V.

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

Perceived Financial Needs, Income Sources, and Subjective Financial Well-Being in an Emerging Market
(Springer Publishing Co, 2019) Kiymaza, Halil; Kiymaz, Halil; Öztürkkal, Belma; Öztürkkal, Ayşe Belma; International Trade and Finance; Business Administration
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.

Productivity Analysis of Black Sea Container Ports by Using Integrated Entropy and Eatwos Methods
(Eskısehır Osmangazı Univ, 2019) Görçün, Ömer Faruk; Görçün, Ömer Faruk; Business Administration
The 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 processes
