Article Citation - WoS: 2Citation - Scopus: 2Effects of Covid-19 Lockdowns on Social Distancing in Turkey(Oxford University Press, 2022-05-23) Bilgel, FıratThis paper elucidates the causal effect of lockdowns on social distancing behaviour in Turkey by adopting an augmented synthetic control and a factor-augmented model approach for imputing counterfactuals. By constructing a synthetic control group that reproduces pre-lockdown trajectory of mobility of the treated provinces and that accommodates staggered adoption, the difference between the counterfactual and actual mobility of treated provinces is assessed in the post-lockdown period. The analysis shows that in the short run following the onset of lockdowns, outdoor mobility would have been about 17–53 percentage points higher on average in the absence of lockdowns, depending on social distancing measure. However, residential mobility would have been about 12 percentage points lower in the absence of lockdowns. The findings are corroborated using interactive fixed effects and matrix completion counterfactuals that accommodate staggered adoption and treatment reversals.Article Citation - WoS: 6Citation - Scopus: 6Effects of Vaccination and the Spatio-Temporal Diffusion of Covid-19 Incidence in Turkey(John Wiley and Sons Inc, 2022-06-04) Bilgel, Fırat; Karahasan, Burhan CanThis study assesses the spatio-temporal impact of vaccination efforts on Covid-19 incidence growth in Turkey. Incorporating geographical features of SARS-CoV-2 transmission, we adopt a spatial Susceptible–Infected–Recovered (SIR) model that serves as a guide of our empirical specification. Using provincial weekly panel data, we estimate a dynamic spatial autoregressive (SAR) model to elucidate the short- and the long-run impact of vaccination on Covid-19 incidence growth after controlling for temporal and spatio-temporal diffusion, testing capacity, social distancing behavior and unobserved space-varying confounders. Results show that vaccination growth reduces Covid-19 incidence growth rate directly and indirectly by creating a positive externality over space. The significant association between vaccination and Covid-19 incidence is robust to a host of spatial weight matrix specifications. Conspicuous spatial and temporal diffusion effects of Covid-19 incidence growth were found across all specifications: the former being a severer threat to the containment of the pandemic than the latter.Article Citation - WoS: 5Citation - Scopus: 4Economic Geography and Human Capital Accumulation in Turkey: Evidence From Micro-Data(Routledge, 2021-02-24) Karahasan, Burhan Can; Bilgel, FıratThis study examines the impact of market access on human capital accumulation in Turkey. Using individual-level data, the analysis explores the background of human capital accumulation, combining market accessibility, wages and human capital development. Upon the treatment of wages as an endogenous covariate of interest and overtime work as an exogenous source of variation, we find evidence that the impact of market access on human capital development vanishes in ways not predicted by the augmented New Economic Geography set-up for human capital accumulation. Findings confirm that economic policies may be effective in reducing regional variation in human capital endowments.Article Citation - WoS: 10Citation - Scopus: 12The Topography and Sources of Multidimensional Poverty in Turkey(Springer, 2021-01-03) Karahasan, Burhan Can; Bilgel, FıratEconomic inequality and poverty have been extensively analyzed in monetary terms. However, other aspects of poverty, such as education, health, environment and standards of living are important factors, essential for human well-being and capabilities. Using a host of non-monetary aspects of poverty, this paper sheds light on the geographical distribution of multidimensional poverty in Turkey. Results from survey data highlight that the regional distribution non-monetary dimensions of poverty is conspicuously different than that of relative monetary poverty in Turkey. Unlike the relative monetary poverty rate, multidimensional poverty measurement reflects the regional underdevelopment problem of Turkey. On the contrary, once monetary poverty is considered in absolute terms, multidimensional and absolute monetary poverty have a similar geographical pattern. Moreover, the decomposition analyses point out that females, old disabled and socially excluded individuals suffer the most from multidimensional poverty. Our combined results show that the isolated eastern regions realize the highest poverty and deprivation at each decomposition level.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.
