Article Plant Size, Turnover and Productivity in Malaysian Manufacturing(2010) Doğan, Ergun; Wong, Koi NyenMalaysian manufacturing has an asymmetrical structure: small and medium-sized enterprises dominate in numbers, but contribute relatively little to total output, employment, and exports as compared to their larger counterparts. In light of an increasingly competitive environment arising from globalization, a sound knowledge of turnover patterns within the sector by plant size and its potential impact on aggregate productivity growth is imperative. We find that turnover, particularly of large plants, makes a substantial contribution to overall productivity growth in manufacturing. Hence, from a policy perspective, facilitating turnover might be as important as supporting existing plants in promoting aggregate productivity growth.Article Nonnormal Regression.I. Skew Distributions(2001) Islam, M. Qamarul; L. Tiku, Moti; Yildirim, F.In a linear regression model of the typey¼ Xþe, it is oftenassumed that the random erroreis normally distributed. Innumerous situations, e.g., whenymeasures life times or reac-tion times,etypically has a skew distribution. We considertwo important families of skew distributions, (a) Weibull withsupport IR:ð0,1Þon the real line, and (b) generalised logisticwit hsupport IR:ð 1,1Þ. Since the maximum likelihoodestimators are intractable in these situations, we derivemodified likelihood estimators which have explicit algebraicforms and are, therefore, easy to compute. We show that theseestimators are remarkably efficient, and robust. We develophypothesis testing procedures and give a real life exampleArticle Is there a Purchasing Power Parity (PPP) Puzzle? New Evidence from a Nonlinear Asymmetric Panel Unit Root Test(2016) Çorakçı, AyşegülThis study re-examines the validity of the purchasing power parity (PPP) hypothesis for 24 OECD countries. The econometric methodology implemented not only allows for asymmetric nonlinear mean reversion within a panel context, but also corrects for the cross-sectional dependence bias frequently encountered in panel data. This feature is important because a test that ignores the presence of asymmetry and cross-sectional dependence when they are in fact present in the data would lead to misleading results. We obtain relatively stronger evidence in favor of the PPP hypothesis when compared to the other alternative panel unit root tests. However, on the whole, this support is still weak even after allowing for asymmetric nonlinear mean reversion in the real exchange rate series. Therefore, to reconcile the data with the theory further methods should be developed.Article Exchange Rate And Bilateral Trade Balance Of Turkey With EU (15) Countries(2014) Yazıcı, Mehmet; Islam, M. QamarulThis paper investigates the short-run and long-run impact of real exchange rate on the bilateral trade balance of Turkey with EU (15) countries. We’ve employed the bounds testing approach to the cointegration and the error correction modeling. Following Yazici and Islam (2011a, 2011b, 2012) and Yazici (2012), we select the optimal model from the set of those models that satisfy both diagnostic tests and cointegration. Thus, unlike the other studies, it is ensured that a statistically reliable and cointegrated model is picked up for estimation. Based on the quarterly data for 1982-I to 2001-IV period, estimation results indicate no evidence of J-curve in the short run in any of Turkey’s bilateral trade with EU(15) countries. In the long run, however, real depreciation of Turkish Lira improves the trade balance of Turkey with Austria, Denmark, France, Ireland, Italy, Sweden and UK.Article Determinants Of Turkish Mining Trade Balance With Eu(15): Estimates From Bound Testing Approach(2016) Yazıcı, Mehmet; Islam, QamarulWe estimate the short-run and long-run determinants of the trade balance of Turkish Mining with EU (15) countries as well as impact of Customs Union (CU) agreement using the bounds testing approach to the cointegration and the error correction modeling. In selecting the optimal model, we follow Yazici and Islam (2011a, 2011b, 2012) and Yazici (2012) and adopt their model selection strategy where selection is made from the set of those models that satisfy both diagnostic tests and cointegrtion, thus ensuring the selection of a statistically reliable and cointegrated model. Estimation results based on the data for 1988-I to 2008-IV period indicate that in the determination of mining trade balance in the short-run only real domestic income matters. Long-run results indicate that real exchange rate and real domestic income variables have coefficients with expected signs but they are not statistically significant. Only statistically significant long-run determinant of mining trade balance is real EU(15) income. Dummy variable for the customs union agreement does not have a statistically significant coefficient, meaning that the agreement does not have a significant long-run effect on mining trade balance of Turkey with EU(15).Article Do Depreciations Really Trigger an Inflow of Foreign Direct Investment? The Case of Turkey(Sosyo Ekonomi Soc, 2018) Erünlü, ZeynepIn 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.
