Article Ülke Risk Primi Şokunun Makroekonomik Etkileri: Türkiye Örneği(2018) Varlık, Nimet; Gebeşoğlu, FulyaÜlke risk primi şokunun makroekonomik etkileri 2005:12- 2017:3 dönemi için Yapısal Vektör Otoregresyon Modeli kullanılarak incelenmiştir. Türkiye için ülke risk primi göstergesi olarak EMBI+TR kullanılan model nominal döviz kuru sepeti, tüketici fiyatları endeksi, tüketici kredileri, sanayi üretim endeksi ve cari açık bilançosunu içermektedir. Ampirik sonuçlar ülke risk priminde gözlenen yapısal şokların Türkiye’nin açık enflasyon hedeflemesi döneminde makroekonomik değişkenlerini olumsuz yönde etkilediğini göstermektedir. EMBI+ TR göstergesindeki bir standart sapmalık şok Türk Lirasında devalüasyona, fiyat seviyesinde artışa, kredi hacminde daralmaya, sanayi üretim endeksinde düşüşe ve cari açık bilançosunda artışa yol açmaktadır. Ülke risk priminin döviz kuru ve krediler üzerindeki olumsuz etkisi diğer değişkenler üzerindeki etkisine kıyasla daha fazladır. Ayrıca ülke risk primi şokları kredi daralması yaratmak suretiyle reel ekonomide küçülmeye ve cari açık bilançosunda artışa yol açmaktadır. Varyans ayrıştırmasının bulguları ile etki tepki analizinin sonuçları tutarlı olupülke risk priminde gözlenen yapısal şokların kredi üzerindeki etkilerinin diğer değişkenlere kıyasla daha fazla olduğu sonucuna varılmıştır.Article Citation - WoS: 9Citation - Scopus: 9Hysteresis and Stochastic Convergence in Eurozone Unemployment Rates: Evidence From Panel Unit Roots With Smooth Breaks and Asymmetric Dynamics(inst Badan Gospodarczych, 2022) Omay, Tolga; Hasanov, Mubariz; Corakci, AysegulResearch background: Studying the dynamic characteristics of unemployment rate is crucial for both economic theory and macroeconomic policies. Despite numerous research, the empirical evidence about stochastic behaviour of the unemployment rate remains disputable. It has been widely agreed that most economic variables, including unemployment rates, are characterized by both structural breaks and nonlinearities. However, a little work is done to examine both features simultaneously. Purpose of the article: In this paper, we analyse the stationarity properties of unemployment rates of Euro area member countries. Also, we aim to test stochastic convergence of unemployment rates among member countries. Our empirical procedures explicitly allow for simultaneous gradual breaks and nonlinearities in the series. Methods: This paper develops a new unit root test procedure for panel data, allowing for both gradual structural breaks and asymmetric adjustment towards equilibrium. We carry out Monte Carlo simulations to examine small sample performance of the proposed test procedure and compare it to the existing test procedures. We apply the newly proposed test to examine the stochastic properties of the unemployment rates of Euro-member countries as well as relative unemployment rates vis-a-vis the Eurozone unemployment rate. Findings & value added: We find that the newly developed test procedure outperforms existing tests in highly nonlinear settings. Also, these tests reject the null hypothesis of unit root in more cases when compared to the existing tests. We find stationarity in the series only after allowing for structural breaks in the data generating process. Allowing for nonlinear and asymmetric adjustment in addition to gradual breaks provides evidence of stationarity in more cases. Furthermore, our results suggest that relative unemployment rate series are stationary, providing evidence in favour of stochastic convergence in unemployment rates. Overall, our results imply a limited room for coordinated economic policy to fight unemployment in the Eurozone.Article Türkiye’de Sinema Sektörünün Geçmişi; Bugünü ve Yarını: Karşılaştırmalı Bir Çalışma(2023) Aktaş, Mansur Konuralp; Doğanay, Mehmet MeteBarındırdığı önemli özellikler sinemayı bir sanat ve eğlence kaynağı olmanın çok ötesine taşımıştır. Sinema ile ilgili yapılan birçok çalışma sinemayı değişik açılardan ele almıştır. Bu çalışmada sinemaya geniş bir perspektiften bakılmış ve sinema ile ilgili yapılan değişik birçok çalışma ile birlikte Internet Movie Database (IMDB)’de yer alan Türk filmleri ile ilgili araştırmalardan yararlanılmıştır. Çalışmanın temel amacı Türkiye’deki sinema sektörünü incelemek olmakla beraber, bir karşılaştırma imkânı sağlaması açısından dünyada sinema endüstrisi alanında önemli yeri olan başta ABD (Hollywood) olmak üzere örnek teşkil edebilecek Hindistan (Bollywood) ve Nijerya (Nollywood) sinema sektörlerinin de değişik açılardan incelenmesidir. Çalışmanın ilk iki bölümünde Hollywood, Bollywood ve Nollywood film endüstrilerinin gelişimi el alınmıştır. Üçüncü bölümde Türk sinemasının doğuşu ve gelişimi incelenmiştir. Çalışmanın dördüncü bölümünde ise Türk sinemasında film içerikleri örneklerle sunulmuştur. Son bölümde ise Türk sinemasının genel bir değerlendirmesi üzerinden Türk sinemasının geleceği üzerine fikirler ortaya atılmaktadır.Article Citation - WoS: 2Citation - Scopus: 2On the Heterogeneous Effects of Tax Policy on Labor Market Outcomes(Wiley, 2022) Adnan, Wifag; Arin, Kerim Peren; Corakci, Aysegul; Spagnolo, NicolaMany recent studies have documented the heterogeneous effects of government-spending shocks on major macroeconomic variables, particularly on output. We delve deeper into the heterogeneous effects of fiscal policy innovations, but focus on the tax policy innovations and their impact on the labor market, while accounting for gender, race, ethnicity, and the business cycle. Using microlevel data from the United States, we find that: (i) Tax shocks have varying employment effects depending on gender, race, and the stage of the business cycle; (ii) Sector, industry, and occupational segregation in labor markets by gender, race, and ethnicity can explain most of the variation in response to fiscal policy shocks.Article Citation - WoS: 2Citation - Scopus: 1Impact 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.Article Citation - WoS: 1Citation - Scopus: 2Profitability of Brokerage Houses in Turkey(Routledge Journals, Taylor & Francis Ltd, 2019) Gunalp, Burak; Kadioglu, EyupThis 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.Article Citation - WoS: 10Citation - Scopus: 15Trade Openness and Industrial Growth: Evidence From Nigeria(Savez Ekonomista Vojvodine, 2017) Adamu, Fahad Muhammad; Dogan, ErgunThis study examines the long-run and short-run relationship between industrial production and trade openness in Nigeria during the period from 1986 to 2008 by using quarterly data. It employs the ARDL bounds testing methodology developed by M. Hashem Pesaran, Yongcheol Shin, and Richard J. Smith (2001). The results of both the long-run analysis and the short-run error correction model (ECM) indicate that trade openness has a significant and positive impact on industrial production. The Toda-Yamamoto causality analysis shows that there is one-way Granger causality, running from trade openness to industrial production.Article Citation - WoS: 8Citation - Scopus: 11Firm Size and Job Creation: Evidence From Turkey(Routledge Journals, Taylor & Francis Ltd, 2017) Islam, M. Qamarul; Yazici, Mehmet; Dogan, ErgunThis study examines the relationship between firm size and job creation by using an extensive data set covering all non-farm Turkish businesses with 20 or more employees from 2003 to 2010. We find that small firms (firms with employees between 20 and 100 employees) have higher mean job flow rates (job creation, job destruction and net job creation rates) than large firms. Firm size and job flow rates are inversely related, and this relationship is especially prominent for firms with 50 employees or more. Although the overall pattern observed is also observed in both sectors, job creation rates in services are higher than the ones in manufacturing. The magnitudes of job destruction rates are comparable across sectors. Higher job creation rate in services but comparable job destruction rate results in higher net job creation rate in services. As for shares, only for smaller firms (20-49 and 50-99 size categories), job creation shares are greater than their shares in employment. But these firms have disproportionate job destruction shares as well. We also find that only the 20-49 category firms contribute to net job creation more than their share in employment. The smaller firms have high disproportionate shares in job creation and destruction in manufacturing and services as well.Article Turkish Agricultural Import and Export Demand Functions: Estimates From Bounds Testing Approach(Routledge Journals, Taylor & Francis Ltd, 2012) Yazici, MehmetThis paper estimates the import and export demand functions for Turkish Agriculture based on the annual data for 1970-2003. The bounds testing approach to the cointegration and the error correction modeling is employed. We, however, adopt a new strategy in the model selection phase and select the optimal model from those models that satisfy both diagnostics and cointegration, thus, unlike the previous literature, ensuring that a statistically reliable and cointegrated model is picked up. Results indicate that for the import demand, relative price is a significant determinant in both short-run and long-run, nominal effective exchange rate matters only in the long-run, but domestic income is not at all a significant determinant for Turkish agricultural import demand. As for the export demand, while all determinants affect the export demand significantly in the short-run, given the relatively small share of Turkish agricultural exports within the world agricultural exports, none individually matters in the long-run.Article Citation - WoS: 4Citation - Scopus: 4Estimation in Multivariate Nonnormal Distributions With Stochastic Variance Function(Elsevier Science Bv, 2014) Islam, M. Qamarul; Qamarul Islam, M.In this paper the problem of estimation of location and scatter of multivariate nonnormal distributions is considered. Estimators are derived under a maximum likelihood setup by expressing the non-linear likelihood equations in the linear form. The resulting estimators are analytical expressions in terms of sample values and, hence, are easily computable and can also be manipulated analytically. These estimators are found to be remarkably more efficient and robust as compared to the least square estimators. They also provide more powerful tests in testing various relevant statistical hypotheses. (C) 2013 Elsevier B.V. All rights reserved.
