    Determinants of Fertility Rates in Turkey
    (Routledge Journals, Taylor & Francis Ltd, 2020) Ozbay Das, Zuhal
    In this study, the fertility changes are examined through the combining political and economic aspects of Turkey. For this purpose, it examines if a long-run relationship between economic and institutional variables and fertility rates of Turkey exists. The long-run relations between income, democracy, polarization, government spending, and fertility rates will thus be analyzed through the Autoregressive Distribute Lag (ARDL) cointegration technique. The results reveal that per capita income, government expenditure, and democracy are one of the key determinants of fertility. Per capita income and government expenditure are negatively associated with fertility, but democracy is positively associated with fertility. The results further showed that the fertility decline is robust after the implementation of compulsory education policy in 1997. The study enlightens the long run effect of government on fertility behavior either through policy implementation or government expenditure, but the association between fertility and institutions in Turkey is rather vague.

    Smart and Sustainable Cities: Challenges and Prospects for Istanbul
    (IGI Global, 2025) Özbay Daş, Z.Ö.
    Rapid urbanization brings about many challenges, such as air pollution, congestion, food insecurity, and waste management. The concepts of "smart city" and "sustainable city" have become very significant for cities that are severely experiencing these types of problems. In this study, the Sustainable Development Goals (SDGs) and smart sustainable indicators are linked to the concept of smart sustainable cities, with a particular focus on assessing Istanbul in this context. As a megacity, Istanbul possesses abundant human capital and a dynamic environment that can provide opportunities for smart and sustainable solutions. However, rapid economic and population growth may simultaneously generate new and complex challenges. © 2026 by IGI Global Scientific Publishing. All rights reserved.

    2000’lı Yıllarda Türkiye Ekonomisi: İmalat Sanayinde Verimlilik Değişimleri
    (2021) Özşahin, Gülşah; Das, Zuhal Ozbay
    Bu çalışmanın amacı, 2000’li yıllarda Türkiye'nin imalat ve hizmet sektörlerinin verimlilik performanslarını tartışmaktır. 2000'li yıllarda Türkiye imalatının yapısal değişiminin yönü konusunda fikir edinmek için bir ayrıştırma analizi uygulanmıştır. Sonuçlar, 2003–2007 döneminde tüm imalat kategorilerinde, emek verimliliğinin düştüğünü, buna karşın 2010–2015 döneminde tüm imalat kategorilerinde emek verimliliğinin arttığını göstermektedir. 2016-2018 döneminde tüm gruplarda emek verimliliği daha da artmıştır, ancak, orta-düşük-teknoloji kategorisinde artış hızı daha yavaş, yüksek-teknoloji endüstrileri durağan bir görünüm sergilemiştir. Hizmet sektöründe emek verimliliği, dönemler itibarıyla imalatta görülenden biraz farklı bir yapı sergilemektedir. Özellikle yüksek teknolojili hizmet grubunda neredeyse tüm dönemlerde nispeten düşük verimli sektörlere doğru bir statik kayma gözlenmiştir. Daha az bilgi yoğun hizmetlerde, emek verimliliği ilk dönemde azalmış, ancak 2010-2015 döneminde belirgin biçimde artmıştır. Sonuçlar, özellikle 2010 sonrası dönemde sanayi politikalarının rolünü tartışmanın anlamlı olduğunu göstermektedir. Bununla birlikte, 2016 sonrasında siyasi ve ekonomik ortamdaki değişiklikler imalat sektöründeki verimlilik değişimlerinin anlaşılmasında ipuçları vermektedir.

    An Empirical Analysis of Gentrification in Istanbul
    (Wiley, 2021) Das, Zuhal Ozbay; Ozsahin, Gulsah
    This paper begins by investigating the occurrence of gentrification in Istanbul during the period of 2008 and 2017, through the application of dynamic system/difference generalized method of moments estimation techniques. Our findings reveal that gentrification seems to have taken hold with the processes of urban regeneration that began in 2012. Additional associations between such parameters as housing price/rent growth, demographic changes, enterprise growth, and political administration (that is, whether the district is overseen by the opposition party or not) are tested through the use of REIDIN sales and rent indices, along with Turkish Statistical Institute data sets for 25 districts in Istanbul and 19 city-centre districts. The results demonstrate that gentrification is closely related to demographics/age and political administration. Overall, while house price/rent growth and enterprise growth are not observed to have an impact on gentrification, the findings of this study reveal that the association between housing prices and gentrification is positive only in those districts governed by the opposition party. The study thus raises questions about the relationship between political attitudes and gentrification in Turkey.

    Turkey on the Fault Line: The Impact of the Earthquake on the Labor Market
    (Wiley, 2025) Demirkilic, Serkan; Ozbay Das, Zuhal; Aydin, Guney
    We assess the impact of the 2011 earthquakes of eastern Turkey on the labor market and the potential resilience strategy by exploring heterogeneity among subgroups. Our findings indicate a rise in low-skilled employment and an increase in the wage rates for low-skilled women following the earthquake. The instant response to earthquakes varies according to the residents' education level. The manufacturing sector was significant in enhancing the workers' resilience. The results further reveal that the return to the family business may have helped to mitigate the negative economic conditions created by the earthquakes.

    Inequality and the Import Demand in Turkey
    (Istanbul Univ, 2021) Ozbay Das, Zuhal
    The study aims to see whether the long-run relation between inequality and import demand exists in Turkey. The Autoregressive Distributed Lag (ARDL) cointegration technique is used in this study to estimate the long-run relationships between real imports, income, relative price, real exports, and inequality for the period 1982-2015. The results revealed that the income elasticity of imports is greater than one as the literature suggests. The sign of the coefficient of relative price and its magnitude is also compatible with the literature, while it is not statistically significant. However, the results further reflect that inequality is positively associated with real imports in Turkey contrary to assumptions of the relation between inequality and imports that is found to be negative for lower income countries in some studies. Short-run coefficients reflect that real income and relative prices are associated with real imports, whereas exports and not surprisingly, inequality variables are not in the short-run. The coefficient of income parameter is less in magnitude in the short-run but still greater than one. However, the sign of the coefficient of the relative price turns out to be positive in the short-run.
