A Qualitative Analysis of Human Resources Practices in Yacht Harbors and Marinas in Türkiye
(2023) Kılıç, Tamer; Yavuzel, Emre; 261218
The study aims to analyze Human Resources Management (HRM) practices, especially Human Resources (HR) planning methods and to develop suggestions for yacht harbors and marinas in Türkiye. The study population comprises 41 yacht harbors and marinas on the Mediterranean, Aegean, and Marmara coasts. Semi-structured interviews are conducted with the HR managers of the companies. The content analysis method is used, the questions in the interview form are collected under three main themes, and the answers received from the participants are converted into data sets under the same themes. Although there is no HR department, the findings reveal that HR practices are carried out with a modern understanding in most yacht harbors and marinas. HR information systems are used in HR planning, recruitment, selection, performance evaluation, compensation, training, and development. Due to the difficulties in recruiting technical personnel in some companies, there are problems in employing eligible candidates at the right place and time. Since employees with higher education in the sector contribute more, they are primarily preferred in recruitment. As a result, with the HR specialists, significant improvements can be made in HRM, especially the efficiency of HR planning in yacht harbors and marinas.

Nonlinearities in emerging stock markets: evidence from Europe's two largest emerging markets
(Routledge Taylor&Francis Group, 2008) Omay, Tolga; Hasanov, Mübariz
Recent developments in time series analysis allow proper modelling of nonlinearities in economic and financial variables. A growing body of research was dedicated to investigation of potential nonlinearities in conditional mean of many economic and financial variables, mainly concentrating in developed economies. However, nonlinearities in financial variables in developing economies have not been fully examined yet. In this article we investigate potential nonlinearity and cyclical behaviour of stock returns in Europe's two largest emerging stock markets, mainly in the Greek and Turkish stock markets. Specifically, we use STAR family models, which allow to model nonlinearities in the conditional mean, for modelling monthly returns on stock exchange indices of the Athens Stock Exchange and Istanbul Stock Exchange. Although we find no nonlinearity in conditional variance, we do find strong evidence in favour of nonlinear adjustment of stock returns. It is found that allowing for nonlinearity in conditional mean results in a superior model and provides good out-of-sample forecasts, which contradicts to efficient market hypothesis

On fractional filtering versus conventional filtering in economics
(Elsevier Science, 2010) Nigmatullin, Raoul R.; Omay, Tolga; Baleanu, Dumitru
In this study, we compare the Hodrick-Prescott Filter technique with the Fractional filtering technique that has recently started to be used in various applied sciences like physics, engineering, and biology. We apply these filtering techniques to quarterly GDP data from Turkey for the period 1988:1-2003:2. The filtered series are analyzed using Minimum Square Error (MSE) and real life evidence. In the second part of the study, we use simulated data to analyze the statistical properties of the aforementioned filtering techniques

Re-examining the threshold effects in the inflation-growth nexus with cross-sectionally dependent non-linear panel: Evidence from six industrialized economies
(Elsevier Science Bv, 2010) Omay, Tolga; Kan, Elif Öznur
This paper analyzes the empirical relationship between inflation and output growth using a novel panel data estimation technique, Panel Smooth Transition Regression (PSTR) model, which takes account of the non-linearities in the data. By using a panel data set for 6 industrialized countries that enable us to control for unobserved heterogeneity at both country and time levels, we find that there exists a statistically significant negative relationship between inflation and growth for the inflation rates above the critical threshold level of 2.52%, which is endogenously determined. Furthermore, we also control cross-section dependency by using the CD test modified to non-linear context and remedy cross-section dependency with Seemingly Unrelated Regression Equations through Generalized Least Squares (SURE-GLS) and newly proposed Common Correlated Effects (CCE) estimation techniques. We find that these methods change the critical threshold value slightly. The estimated threshold values from these estimation methods are 3.18% and 2.42%, respectively. (C) 2010 Elsevier B.V.

Rethinking Fisher Effect with New Keynesian Phillips Curve
(2019) Uçar, Nuri; 189073
I modify and enlarge the simple Fisher equation by including different inflation dynamics and multiple common unobservable factors. I investigate the long runrelationship by carrying out a series of estimators and models that have been developed recently. I observe that augmentation of Fisher equation leads to provide the supportive evidence for the long run relationship between nominal interest rate and inflation.

Testing Stochastic Income Convergence In Seasonal Heterogeneous Panels
(Elsevier, 2010) Uçar, Nuri; Güler, Hüseyin; 189073
In this paper we introduce a seasonal version of the Solow-Swan growth model and acquire an empirical income convergence equation. We take this equation as a basis to investigate whether income convergence exists in an OECD sample. To do this, we propose the test statistics under various asymptotic properties for some of the seasonal frequencies in the context of nonstationary heterogeneous panels. Critical values and moments of our statistics are generated and their finite sample performances are examined via Monte Carlo simulations. (C) 2009 Elsevier B.V. All rights reserved.

The dynamics of financial literacy within the framework of personal finance: An analysis among Turkish University Students
(Academic Journals, 2011) Altıntaş, Kadir Murat; 17561
Poor financial choices could have a number of negative consequences for young people. Financially illiterate graduates might be subject to various financial or judicial enforcements, such as bankruptcy, mortgage crises or financial frauds. In order to protect young adults from the costly consequences of financial illiteracy, the evaluation of financial literacy must be analyzed for transforming them into financially knowledgeable individuals by the help of financial education. The main purpose of this study is to reveal the special characteristics that influence the financial literacy of university students, as well as to evaluate their financial literacy level. Results show that university students do not have adequate knowledge on personal finance and financial management, in other words they need to enhance their financial literacy in order to protect their financial security at the medium and long run. In addition, the most important factors that affect the overall personal financial literacy of university students within the framework of the survey are class rank, age, family's income level, and students' discussion potential with their parents about financial matters

The effects of inflation uncertainty on interest rates: a nonlinear approach
(Routledge Taylor&Francis Group, 2010) Omay, Tolga; Hasanov, Mübariz
In this article, we investigate the effects of inflation variability on short-term interest rates within a nonlinear smooth transition regression framework. The test results suggest that only the conditional mean of the inflation is a nonlinear process whereas the conditional variance is time variant but linear. Using the square root of conditional variance as a proxy for inflation risk, we estimate Fisher equation augmented with inflation risk. Although the estimated Fisher equations suggest that inflation risk reduces short-term interest rates, we find that the effects of inflation risk on interest rates are regime-dependent. Particularly, we find that the negative effects of inflation variability on nominal rates are greater in low-inflationary regimes when compared to high-inflationary regimes. On the other hand, it is found that both inflation and inflation uncertainty raise the expected inflation effect

The endogenous and non-linear relationship between terrorism and economic performance: Turkish evidence
(Taylor&Francis INC, 2009) Arın, K. Peren; Omay, Tolga; Araz, Bahar; 177438
This paper investigates the macroeconomic effects of terror by using a novel data set from Turkey for the period of 1987:1 to 2004:4. This research contributes to the literature by controlling for the possible non-linear and endogenous relationship between political conflict and economic activity. Empirical evidence from both linear and non-linear models confirms that terrorism has a large significant negative impact on economic activity. Finally, the results from the non-linear model show that the impact of terrorism on the aggregate economy is more severe during expansionary periods, and that the impact of economic activity on terrorism is significant only in recessionary periods

The relationship between inflation, output growth, and their uncertainties: evidence from selected CEE countries
(M E Sharpe Inc, 2011) Hasanov, Mübariz; Omay, Tolga
In this paper, we examine causal relationships between inflation rate, output growth rate, inflation uncertainty, and output uncertainty for ten Central and Eastern European transition countries. For this purpose, we estimate a bivariate GARCH model that includes output growth and inflation rates for each country. Then we use conditional standard deviations of inflation and output to proxy nominal and real uncertainty, respectively, and perform Granger causality tests. Our results suggest that inflation rate induces uncertainty about both inflation rate and output growth rate, which is detrimental to real economic activity. At the same time, we find that output growth rate reduces macroeconomic uncertainty in some countries. In addition, we also examine and discuss causal relationships between the remaining variables
