    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 Finansman
    Regarding 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.

    Ppp Hypothesis and Temporary Structural Breaks
    (Economics Bulletin, 2017) Corakci, Aysegul; Omay, Tolga; Emirmahmutoglu, Furkan; Çorakcı, Ayşegül; Tolga, Omay; Çankaya Meslek Yüksekokulu; İktisat
    In 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.

    Model 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.; İktisat
    Selecting 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.

    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.

    Impact of Exchange Rate and Customs Union on Trade Balance at Commodity Level of Turkey With Eu (15)
    (Routledge Journals, Taylor & Francis Ltd, 2011) Islam, M. Qamarul; Yazici, Mehmet; Qamarul Islam, M.
    This paper investigates the short-run and long-run impact of exchange rate and customs union on the trade balance at commodity-group level of Turkey with EU (15). Bounds testing approach is employed where a new strategy in the model selection phase is odopted ensuring that optimal model is selected from those models satisfying both diagnostics and cointegration. Results indicate that in the short-run exchange rate matters in determination of trade balance of 13 commodity groups out of 21 and customs union in 8 cases. Pattern of response of trade balance to exchange rate does not suggest a J-curve effect in any of cases. As for the long-run effect, neither exchange rate nor customs union has a statistically significant effect on trade balance of any of commodity groups, suggesting that those significant short-run effects don't last into long-run.

    Innovation Cluster Development Potential in the Regions of Turkey: a Geographical Perspective
    (Igi Global, 2013) Sakarya, Arif Orcun
    The assessment of firms' innovativeness levels in a specific territory can be assumed to be an important indicator of future innovative collaboration, some of which might also be cluster setup initiatives. Assuming that geographical proximity can also provide a favorable opportunity for strengthening interfirm ties, the goal of the chapter is to discover the best innovation variables for Turkish firms in terms of being members of potential innovative cluster formations. Following an overview of the innovation parameters used in the study, the current situation of the firms in question and their problems are briefly stated. The analysis part includes a regression test to discover the variables affecting firms' innovativeness in order to tackle the problems stated. Regression results have shown that intellectual capital, technology infrastructure, and geographical concentration levels affect the innovation performance of the firms in different regions. The conclusion involves further policy improvements for empowering regional innovation capabilities.

    Profitability of Brokerage Houses in Turkey
    (Routledge Journals, Taylor & Francis Ltd, 2019) Gunalp, Burak; Kadioglu, Eyup
    This paper uses a direct measure of efficiency to examine the relationship between market structure and the performance of brokerage houses in Turkey. This methodology involves two stages: First, a stochastic translog cost frontier is specified to obtain a direct measure of efficiency. Second, this measure is included in a profitability equation along with market concentration and market share variables. These two equations are then estimated using quarterly data from 112 brokerage houses for the period 2008-2015. The results show that the efficiency of brokerage houses does not influence profitability when measured directly. Market share, on the other hand, is found to be one of the main determinants of profitability, providing support for the relative market power hypothesis.

    Do Depreciations Really Trigger an Inflow of Foreign Direct Investment? The Case of Turkey
    (Sosyo Ekonomi Soc, 2018) Erünlü, Zeynep
    In this study, the relationship between real exchange rate and foreign direct investment is examined using the Logistic Smooth Transition - Autoregressive Distributed Lag (LST-ARDL) model. Analyzing the effect of real exchange rate changes on foreign direct investment is very crucial for a developing country like Turkey which has a relatively large foreign debt stock. The estimation results show that foreign direct investment inflows to Turkey increase when Turkish Lira appreciates against the US dollar and this effect is especially strong during periods of high investment inflows. Thus, for Turkey to attract productive capital flows rather than unstable short-term portfolio flows it has to maintain a strong currency against the US dollar.
