My Work Experience

Consultant

Social Protection and Jobs Global Practice • Examined the relation between management practices of Turkish manufacturing firms and their performance using fixed effects models and elaborated on the causes of heterogeneity in management practices across firms. In line with the literature, better managed firms perform better. Product market competition and firm level factors such as size, multinational status, work effort put by the workforce, the level of managerial hierarchy and ownership are found to be significant determinants of management practices. Family ownership combined with family management is a significant deterrent of good management practices and is strongly associated with declines in firm performance. • Investigated whether better management practices that increase performance come at the expense of employees’ work-life balance (e.g., longer work hours, intense work, lower levels of job satisfaction). The findings argue on the contrary that better managed firms provide better working conditions to their employees, resulting in improved employee wellbeing. • Conducted empirical research using Enterprise Information System (EIS) database—administrative big data covering the universe of formal Turkish firms and workers with more than 100 million observations—from Turkish Ministry of Industry and Technology to infer automation from relative employment declines in low wage jobs that are routine intensive in response to minimum wage hikes. The econometric analysis employs difference-in- differences estimation strategy in Stata. • Prepared a report summarizing the vast literature on socio-economic impacts of Syrian refugees in Turkey focusing on labor market outcomes, firm performance and firm creation, prices, education outcomes, health outcomes, and crime.

Poverty and Equity Global Practice • Conducted statistical analysis of Turkish labor market dynamics during the period 2015-2018. Via exploiting variation in Turkish Household Labor Force Surveys and other related data sets, produced tables and charts in Stata that summarize the change in key labor market outcomes during the study period including hourly wages, labor force participation, unemployment, etc. • Investigated the evolution of regional income inequality in Turkey from the standpoint of income convergence hypotheses (absolute and conditional β convergence) and tested whether regional income convergence is accompanied by poverty convergence during the 2004-2019 period. This study is novel in suggesting the clustered growth patterns of Turkish regions for the absence of regional poverty convergence in a context of strong economic growth accompanied by significant reductions in regional income discrepancies. • Focusing on urbanization, agglomeration economies, labor mobility, and regional growth policies among others, examined the main drivers and constraints to progress toward regionally inclusive prosperity in Turkey; communicated the results with internal stakeholders and various government agencies including Ministry of Industry and Technology, and Ministry of Treasury and Finance; and contributed to a report that proposes an evidence- based policy framework to address remaining bottlenecks so that the gains of future economic progress are more broadly shared (“Prosperous Places: Advancing Spatially Inclusive Development in Turkey” forthcoming World Bank Report).

Working Group Member

Working Group Member for the Action "Connecting Theory and Practical Issues of Migration and Religious Diversity" (CA20107) • The COST Action “Connecting Theory and Practical Issues of Migration and Religious Diversity” is an interdisciplinary network that aims at knowledge production, knowledge exchange and capacity building across Europe in the intersection of migration and religious diversity. The background of the network is the pressing social situation that is characterized by the fact that migrants and Syrian war refugees coming to Europe, have become one of the major political issues and social challenges during the past years. This network brings the bridging of knowledge with stakeholders – governmental, non-governmental and media organizations – working in the field of diversity management on the local and national levels. I am a member of the following Working Groups: o Meta-study on the Intersection between Religion and Migration o Design of Practice-Orientated Research Projects o Migration and Religious Diversity through the Lenses of Gender and Age

World Food Programme | Sep 2019 - Jul 2020

Researcher

• Prepared a report coauthored by Abdurrahman B. Aydemir for WFP on the effects of ESSN (Emergency Social Safety Net) on national and local economy in Turkey. ESSN is currently the largest humanitarian cash transfer program on the world aiming to support the most vulnerable Syrian refugees under temporary protection in Turkey via monthly cash transfers. The ESSN is implemented in partnership with the Turkish Government, Türk Kızılay, European Union and the World Food Programme, and is funded under the Facility for Refugees in Turkey. The analysis focuses at national level on output multiplier effects and at province level on education, health, labor market and price effects of ESSN and uses difference-in-differences strategy to estimate the treatment effects. This is the first study to investigate the indirect impacts of such an unprecedented large-scale humanitarian assistance program on the economy. The results are presented at the following conferences: o ERF 27th Annual Conference, presented “The effects of ESSN cash transfers on national and local economy”, June 16, 2021, Dokki, Giza, Egypt o Immigration, Integration and Attitudes, workshop in Mannheim, presented “The effects of ESSN cash transfers on national and local economy”, Sept 22-23, 2020, ZEW Mannheim and the Mannheim Centre for European Social Research (MZES) at the University of Mannheim, Germany

TÜBİTAK | Sep 2018 - Jan 2019

Researcher

• Thanks to the Research Grant provided by TUBITAK - The Scientific and Technological Research Council of Turkey, conducted a comparative statistical analysis of labor market outcomes of Turkish immigrants in various European countries using LIS (Luxembourg Income Study) database within LISSY platform. The quasi-experimental techniques employed for causal inference are fixed effects linear regression models and propensity score matching models.
