Article Citation - WoS: 1Legislation on Ottoman Copyright Law(Selcuk Univ, inst Turkish Studies, 2007) Çakmak, Diren; Cakmak, Diren; Siyaset Bilimi ve Uluslararası İlişkilerIn this study the age of copyright law in Turkey is 157 years is determined and, the fact that copyright as a term has entered in our country in the year 1850 with Statute of Encumen-i Danis, the first legal text on copyright is Statute of Copyright dated 1857, Statute of Copyright and Translation dated 1870 is compensatory legal text of Statute of Copyright, the second legal text on copyright is Code of Copyright dated 1910 is determined.Article Supply Response of the Wine Industry in Turkey(Asia Life Sciences, 2011) Sakarya, Arif Orçun; Sakarya, Arif Orcun; Temiz, Dilek; Temiz, Dilek; İşletme; Uluslararası Ticaret ve FinansmanRegarding the high wine production potential; the main goal of the study is to discover whether there is a long run relationship between wine production, wine net export and demand and to display the possible contribution of latter variables on wine production in Turkey. Following the wine market overlook; related contribution is analyzed by using annual time series data for the years 1961-2005, the Johansen cointegration test and ordinary least squares method. The empirical findings have shown that, as the wine net export or the wine demand increases, wine production also increases in Turkey. Cointegration test has proved that there is a long run relationship between wine production and the other variables.Article Citation - WoS: 11Citation - Scopus: 9Ppp Hypothesis and Temporary Structural Breaks(Economics Bulletin, 2017) Corakci, Aysegul; Omay, Tolga; Emirmahmutoglu, Furkan; Çorakcı, Ayşegül; Tolga, Omay; Çankaya Meslek Yüksekokulu; İktisatIn this study our aim is to explore a better testing strategy for the PPP hypothesis under a temporary structural break. For this purpose we use the exponential smooth transition (EST) function in the unit root testing framework and compare this methodology with the one that uses a Fourier function. Although the Fourier function is extensively used in the literature to test the validity of the PPP hypothesis under temporary breaks, this investigation shows that it leads to misleading results.Article Citation - WoS: 1Citation - Scopus: 1Model Selection Uncertainties and Model Averaging in Autoregressive Time Series Models(Isoss Publ, 2012) Islam, M. Qamarul; Yazıcı, Mehmet; Yazici, Mehmet; Islam, M.Qamarul; Qamarul Islam, M.; İktisatSelecting the correct lag order is necessary in order to avoid model specification errors in autoregressive (AR) time series models. Here we explore the problem of lag order selection in such models. This study provides an in-depth but easy understanding of the model selection mechanism to the practitioners in various fields of applied research. Several interesting findings are reported and through these the pitfalls of the model selection procedures are exposed. In particular, we show that the whole exercise of model selection and subsequent statistical inference invariably depends upon unknown entities, namely the true values of parameters in the model. The model averaging technique is proposed as an alternative to the common practice of model selection and it is shown that, as a result, the properties of post-model-selection estimates substantially improve.Article Multiple linear regression model under nonnormality(Taylor & Francis Inc, 2004) Islam, M. Qamarul; Tiku, Moti L.We consider multiple linear regression models under nonnormality. We derive modified maximum likelihood estimators (MMLEs) of the parameters and show that they are efficient and robust. We show that the least squares esimators are considerably less efficient. We compare the efficiencies of the MMLEs and the M estimators for symmetric distributions and show that, for plausible alternatives to an assumed distribution, the former are more efficient. We provide real-life examples.Article Citation - WoS: 10Citation - Scopus: 7Distinct Asymmetric Effects of Military Spending on Economic Growth for Different Income Groups of Countries(Taylor & Francis Ltd, 2023) Ocal, Nadir; Yildirim, Julide; Karadam, Duygu Yolcu; Yolcu Karadam, DuyguAlthough possible asymmetries for univariate and multivariate dynamics have been the focus of interest in many areas of economic explorations, it seems that most of the research on military expenditure - economic growth nexus has tended to assume linear relationships. This paper aims to examine possible nonlinearities in military expenditure-economic growth nexus employing data for a sample of 103 countries covering the 1988-2019 period. For this purpose, Panel Smooth Transition Regression, PSTR, models are estimated not only for all countries' sample but also for low income, middle income, and high-income countries' subsamples to reveal possible distinct asymmetric relationships for country groups with different income levels. Empirical results for the whole sample, low income and middle income groups indicate that military expenditure not only governs the regime change, but also low and high levels of military expenditure have distinctive and rising negative effects on economic growth with dissimilar threshold effects. Moreover, empirical findings also indicate that net arms exports govern regime change for high income countries, and as net arms exports rise, the negative impacts of military expenditure on economic growth become deeper.Article Citation - WoS: 4Citation - Scopus: 5Analysis of Distinct Asymmetries in Financialintegration-Growthnexus for Industrial, Emerging and Developing Countries(Wiley, 2022) Ocal, Nadir; Yolcu Karadam, DuyguThis paper examines the threshold conditions in financial integration and growth relationship for a large set of threshold variables and different income group of countries employing Panel Smooth Transition Regression Models. Except developing countries, our findings strongly indicate nonlinear dynamics and imply that the impact of financial integration on growth is asymmetric depending on a number of indicators such as countries' degree of institutional quality, financial sector development, trade openness, budget deficit, inflation volatility and the level of financial integration. Our results show that these threshold effects substantially differ for emerging and industrial countries. As far as whole set of countries is concerned, our findings imply that countries having developed financial systems, qualified institutions and stable macroeconomic environment benefit from financial integration. Moreover, threshold effects are stronger and different for emerging countries compared to the industrial countries. Unlike emerging economies, higher levels of financial integration and trade openness decrease benefits from financial openness for the industrial countries. Besides, high fiscal deficit has more pronounced negative effect on the growth of the industrialized countries compared to emerging economies and other indicators.Article Citation - Scopus: 5Analysis of distinct asymmetries in financial integration‐growth nexus for industrial, emerging and developing countries(John Wiley and Sons Ltd, 2020) Yolcu Karadam, Duygu; Öcal, NadirThis paper examines the threshold conditions in financial integration and growth relationship for a large set of threshold variables and different income group of countries employing Panel Smooth Transition Regression Models.

This paper examines whether knowledge spillovers are prevalent among ASEAN-5, focusing on the issues of which channels and which sources are the potential drivers of total factor productivity. The findings reveal that the key spillover channels are exports and non-capital imports coming from source countries such as the Organisation for Economic Co-operation and Development (OECD) countries, the G7 countries. The institutional quality plays an instrumental role in increasing total factor productivity through foreign direct investment, especially when the spillovers originate from the OECD and the G7.

Controlling for several demographic and economic variables including the Fraser Institute's Economic Freedom Index (EFI), which measures the size and scope of government in U.S. states, we find a positive and statistically significant relationship between federal regulations and corruption. Our findings have important policy implications. A 1 standard deviation increase in FRASE Index causes CCI to increase by approximately 0.5 standard deviations. Standardized coefficient of EFI is also approximately equal to 0.5. In other words, it is possible to mitigate the effects of regulations at the federal level by reducing the size and the scope of the government at the state level.
