Article Quality of Government Cohesion Across EU Regions: Success or Failure(Routledge Journals, Taylor & Francis Ltd, 2026-01-16) Karahasan, Burhan CanRegional differences in institutions is a threat for political and economic integration. In this paper, we analyse the institutional convergence across regions of the European Union (EU). Preliminary results show that there is continuous improvement fostering institutional convergence. However, heterogeneity analyses point-out that the speed of institutional development is influenced by the enlargement phases of the union. Additional results indicate that the regions of the Central and Eastern European (CEE) countries and the southern regions belonging to Greece and Spain experience faster institutional convergence. Accordingly, the enlargement process, fostering further heterogeneity, is an important element to improve the institutional quality of the new EU members. However, temporal convergence trends show that the dynamics of institutional convergence shift over time, reflecting the non-stationary evolution of success-failure cases.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 - WoS: 1Citation - Scopus: 1Understanding Covid-19 Mobility Through Human Capital: a Unified Causal Framework(Springer, 2023-02-21) Bilgel, Fırat; Karahasan, Burhan CanThis paper seeks to identify the causal impact of educational human capital on social distancing behavior at workplace in Turkey using district-level data for the period of April 2020 - February 2021. We adopt a unified causal framework, predicated on domain knowledge, theory-justified constraints anda data-driven causal structure discovery using causal graphs. We answer our causal query by employing machine learning prediction algorithms; instrumental variables in the presence of latent confounding and Heckman's model in the presence of selection bias. Results show that educated regions are able to distance-work and educational human capital is a key factor in reducing workplace mobility, possibly through its impact on employment. This pattern leads to higher workplace mobility for less educated regions and translates into higher Covid-19 infection rates. The future of the pandemic lies in less educated segments of developing countries and calls for public health action to decrease its unequal and pervasive impact.Article Citation - WoS: 1Citation - Scopus: 1Great Recession and News Shocks: Evidence Based on an Estimated Dsge Model(Springer, 2021-05-21) Nebioğlu, DenizThis paper examines whether productivity news shocks were among the drivers of the Great Recession. To do this, the Smets and Wouters (Am Econ Rev 97(3):586–606, 2007. https://doi.org/10.1257/aer.97.3.586) model is extended by a generalized preference specification which allows for scaling wealth effects on the labor supply. The resulting model is estimated using Bayesian methods which draw upon the US data from the period 1965Q2 to 2014Q3. There are four main results: (i) Estimation of the model is inconclusive regarding the degree of wealth elasticity of the labor supply. As a result, two complementary versions of the model prevail, each of which has differing implications for the transmission and the quantitative importance of exogenous shocks. (ii) When the degree of wealth elasticity of the labor supply is low, news shocks replace risk premium shocks, suggesting that news shocks are one possible reason for fluctuations in US business cycles. (iii) When the Great Recession period is analyzed through the lenses of the two complementary versions of the model, two explanations emerge as potential reasons behind the deepening of the crisis: worsening credit conditions as well as the collapse of over-optimistic expectations regarding future productivity. (iv) For both model specifications, general developments in productivity are estimated to be positive. Therefore, productivity slowdown is not considered to be among the reasons for the emergence or persistence of the Great Recession.Article Citation - WoS: 47Citation - Scopus: 72Adoption and Use of Learning Management Systems in Education: the Role of Playfulness and Self-Management(MDPI [Commercial Publisher], 2021-01-22) Akküçük, Ulaş; Balkaya, SelenThis article investigates the factors affecting primary and secondary education teachers' behavioral intention to adopt learning management systems (LMSs). Information technology (IT) innovations have the power to change the way we work, educate, learn, and basically the way we live. The effect of IT innovations on education makes it critical to understand the current usage situation of LMSs and the factors affecting their adoption by teachers. The unified theory of acceptance and use of technology (UTAUT) was extended with factors from education and game-based learning literature. In order to see the effect of individual- and organizational-level characteristics, multi-group structural equation modeling (SEM) analysis was conducted and discrepancies in relationships were reported. Evaluation of users and non-users and teachers of different fields were also compared to each other. The findings of this study not only contribute to theory through the development and testing of a thorough model relating technology features and individual characteristics to behavioral intention to use, but also offer strong implications for practitioners who would like to increase LMS usage and create a more effective learning environment.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 State Gun Control Laws, Gun Ownership and the Supply of Homicide Organ Donors(Elsevier, 2020-09-01) Bilgel, FıratThe likelihood of being a potential deceased organ donor is higher for individuals who have been exposed to situations typically characterized by a severe head trauma or stroke that result in brain death. Employing count data models that account for overdispersion and/or excessive counts of zeros, this paper assesses the unintended consequences of enforcing stricter gun control laws and the effects of gun ownership on homicide organ donor supply in the United States using county data for the period 2009–2015. The findings confirm the transplantation paradox hypothesis that stricter gun control laws reduce the expected cases of gun homicides and thereby reduce deceased organ donor supply and exacerbate the organ shortage. The findings are robust to several measures of the strength of gun control laws, restricted samples and spurious outcome variables. However, the direction of the impact of gun ownership levels on homicide organ donor supply proved to be inconclusive.
