Article Citation - WoS: 1Unemployment Polarisation and Club Convergence in Türkiye(Wiley, 2025-02-04) Karahasan, Burhan CanTurkish economy has undergone massive transformation during the 2000s. Annual economic growth reached a peak of 10% in the early 2000s. However, the side effects of global financial crises and the internal macroeconomic imbalances shift the growth trajectory of T & uuml;rkiye into a new path of unstable economic growth. While macroeconomic consequences are densely discussed we know less about the adjustment of local labour markets. To fill this gap, we examine the club formation of Turkish regions by analysing their unemployment trajectories during the post 2000s. Our findings show that despite rapid economic growth Turkish regions get extremely polarised and form distinct convergence clubs. Remarkably polarisation is higher for the female population. Geographically, polarisation is in the form of an isolation for the least developed south-eastern regions and some of the developed urbanised western regions. Additionally, our robustness exercises indicate higher polarisation after 2013 as Turkish economic growth starts to become more volatile and less sustainable. Finally, our spatial extensions show that impact of spatial proximity has significant influence on the accurate extent of unemployment deprivation.Article Citation - Scopus: 1Infant Mortality in Turkey: Causes and Effects in a Regional Context(Wiley, 2021-04-01) Bilgel, FiratThis study attempts to identify the causal and/or direct effects of sociocultural determinants of infant mortality in Turkey within a regional context using causal graph analysis and global and local spatial models. The conceptual framework, combined with the data, shows that fertility and consanguinity have direct effects on infant mortality rates, and that female illiteracy, as a proxy for maternal education, is the main cause of rising infant mortality even in the presence of latent confounding. The surface of estimates further shows that the local effects of female illiteracy and consanguinity are non-stationary across space, calling for location-specific policies.Article Citation - WoS: 3Citation - Scopus: 4State–business Relations, Financial Access and Firm Performance: a Causal Mediation Analysis(Wiley, 2020-09-01) Karahasan, Burhan Can; Bilgel, FıratThis study investigates the triangular relationship among state–business relations, financial access and economic performance in the Middle East and North Africa. We hypothesize that financial intermediation is a significant mediating factor in the relationship between state–business relations and firm performance. Employing a causal mediation analysis, results show that inefficient ties with the state are a cause of poor firm performance. Inefficient state–business relations reduce firm performance by 2.3 to 4.4 per cent through access to finance and by 12 to 40 per cent via its direct effect. About 3 to 16 per cent of the total effect is mediated through financial access, while the remaining is the direct effect.Article Citation - WoS: 8Citation - Scopus: 8Market Access and Regional Dispersion of Human Capital Accumulation in Turkey(Wiley, 2020-05-27) Karahasan, Burhan Can; Bilgel, FıratBuilding on early advances in development economics, the theoretical construct of new economic geography asserts that geography plays a crucial role in educational human capital accumulation. Based on this expectation, this study investigates the impact of market access on provincial human capital accumulation in Turkey. Results indicate that market access matters for understanding why some regions lag behind others in terms of average years of schooling. Our results are robust to the inclusion of spatial mechanisms, different specifications of the spatial weight matrix, endogeneity and alternative measurements of market access and to a host of other factors that affect regional human capital accumulation.Article Citation - WoS: 19Citation - Scopus: 20Guns and Homicides: a Multiscale Geographically Weighted Instrumental Variables Approach(Wiley, 2019-12-23) Bilgel, FıratThis article assesses the locally varying effects of gun ownership levels on total and gun homicide rates in the contiguous United States using cross-sectional county data for the period 2009–2015. Employing a multiscale geographically weighted instrumental variables regression that takes into account spatial nonstationarity in the processes and the endogenous nature of gun ownership levels, estimates show that gun ownership exerts spatially monotonically negative effects on total and gun homicide rates, indicating that there are no counties supporting the “more guns, more crime” hypothesis for these two highly important crime categories. The number of counties in the contiguous United States where the “more guns, less crime” hypothesis is confirmed is limited to at least 1258 counties (44.8% of the sample) with the strongest total homicide-decreasing effects concentrated in southeastern Texas and the deep south. On the other hand, stricter state gun control laws exert spatially monotonically negative effects on gun homicide rates with the strongest effects concentrated in the southern tip of Texas extending toward the deep south.Article Citation - WoS: 6Citation - Scopus: 10Gendering Resistance: Multiple Faces of the Kurdish Women's Struggle(Wiley, 2019-08-08) Göksel, NisaThe article explores the Kurdish women's movement in Turkey by bridging two forms of resistance: those of guerrilla women fighters and of activist women. Based on my extensive ethnographic and archival research, I ask how women under conditions of war engage in different modes of resistance. In what ways does the "heroic resistance" of guerrilla women resonate with and/or contradict the everyday, "ordinary" struggles of activist women? The potent image of the Kurdish guerrilla woman that emerged in the early 1990s is constitutive of many other modes of political subjectivities, even among women who do not or cannot become guerrillas. One of those subjectivities is that of the activist woman. My analysis suggests that women's activism opens up a middle ground of action between "heroic" and "ordinary" resistance by reconciling revolutionary politics with everyday activism around gender-based violence, democracy, and human rights. Although both revolutionary movement participants and scholars of revolutionary resistance often contrast the "ordinary" with the realm of armed resistance, this article challenges this dichotomy. I take the two realms of resistance-the ordinary and the heroic-as the core constituents of revolutionary resistance, and I reconsider the gendered interplay between them.Article Citation - WoS: 4Citation - Scopus: 6Does the Unification of Health Financing Affect the Distribution Pattern of Out-Of Health Expenses in Turkey?(Wiley, 2019-04-07) Çınaroğlu, Songül; Başer, OnurTurkey has implemented health reforms for over a decade and has taken significant steps toward unifying health financing. This study investigated the financial burden associated with out-of-pocket (OOP) expenditures under universal health coverage, using national 2003–2015 household budget data from the Turkish Statistical Institute. Progress was evaluated using Kakwani–Suits indices and Lorenz concentration curves. The results indicate that overall, more than a decade after its unification, redistribution of wealth in the Turkish health financing system has benefitted the wealthy but not the poor. Both curve and index approaches (Kakwani index 2003 = -0.50; 2015 = -0.44) reveal an increasingly regressive pattern of OOP health expenditures. The effective use of fiscal space and good political leadership are essential for the successful continuation of reforms to combat poverty in Turkey.Article Citation - WoS: 13Citation - Scopus: 13Therapeutically Interchangeable? a Study of Real-World Outcomes Associated With Switching Basal Insulin Analogues Among Us Patients With Type 2 Diabetes Mellitus Using Electronic Medical Records Data(Wiley, 2014-12-04) Wei, W.; Gill, J.; Ye, F; Xie, L; Levin, P.; Miao, R.; Başer, OnurAims: To evaluate real-world clinical outcomes for switching basal insulin analogues [insulin glargine (GLA) and insulin detemir (DET)] among US patients with type 2 diabetes mellitus (T2DM). Methods: Using the GE Centricity Electronic Medical Records database, this retrospective study examined two cohorts: cohort 1, comprising patients previously on GLA and then either switching to DET (DET-S) or continuing with GLA (GLA-C); and cohort 2, comprising patients previously on DET and then either switching to GLA (GLA-S) or continuing with DET (DET-C). Within each cohort, treatment groups were propensity-score-matched on baseline characteristics. At 1-year follow-up, insulin treatment patterns, glycated haemoglobin (HbA1c) levels, hypoglycaemic events, weight and body mass index (BMI) were evaluated. Results: The analysis included 13 942 patients: cohort 1: n= 10 657 (DET-S, n= 1797 matched to GLA-C, n= 8860) and cohort 2: n= 3285 (GLA-S, n= 858 matched to DET-C, n= 2427). Baseline characteristics were similar between the treatment groups in each cohort. At 1-year follow-up, in cohort 1, patients in the DET-S subgroup were significantly less persistent with treatment, more likely to use a rapid-acting insulin analogue, had higher HbA1c values, lower HbA1c reductions and lower proportions of patients achieving HbA1c < 7.0 or < 8.0% compared with patients in the GLA-C subgroup, while hypoglycaemia rates and BMI/weight values and change from baseline were similar in the two subgroups. In cohort 2, overall, there were contrasting findings between patients in the GLA-S and those in the DET-C subgroup. Conclusions: This study showed contrasting results when patients with T2DM switched between basal insulin analogues, although these preliminary results may be subject to limitations in the analysis. Nevertheless, this study calls into question the therapeutic interchangeability of GLA and DET, and this merits further investigation.Article Citation - WoS: 5Citation - Scopus: 5Evidence for Financial Contagion in Endogenous Volatile Periods(Wiley, 2015-01-27) Ulusoy, Veysel; Kılıç, ErdemThe objective of this study is to analyze cross-border contagious dynamics in both foreign exchange markets and stock exchange markets. Propagation is analyzed with respect to the transmission of excessive volatility that is endogenously determined. The contagion process is discussed in the context of financial systems, foreign direct investments and trade. Implementing a vector autoregressive-multivariate generalized autoregressive conditional heteroskedasticity (VAR-MGARCH) model, we show that country-specific turbulence in financial markets is able to create unanticipated financial contagion across countries. Diversified trade and financial relations decrease the risk of exposure to contagion from external markets. The world's largest economies, however, play a price-setter role, and diversification is of secondary importance. Asymmetric transmission of the empirically predicted contagion prevails in the latter case.
