Essays in Applied and Labor Economics

This thesis consists of three chapters. First and second chapter include original research papers with the focus of health behavior and refugee migration. In the context of a high-income developing country, Turkey, I provide new insights for the established policy discussions in the literature. Then, third chapter reviews the literature and perspectives on the determinants of attitude formation towards migration policy and migrants. This chapter extends the discussion in Chapter 2 and aims at understanding the reasons of recent global trends in anti-migration attitudes. In Chapter 1, I investigate the effects of education on the early investments of mothers in their children aged between 0-5. Exploiting a compulsory schooling reform, I document the causal effects of education on young mothers' health investments during pregnancy and postnatal period. Results suggest that there are positive effects on the use of health care services, while no effects on breast- feeding or vaccination take-ups. These results can be put into context through newly implemented Health Transformation Program in the country. I show that educated mothers use new services more and empowerment effects of the education have a role in the service use. This study gives important policy lessons to improve mothers' health care use and early child conditions in developing countries. In Chapter 2, I investigate the effects of refugee inflow on the voting behavior of natives. I use a novel data provided by a telecommunication company, focus on pre and post refugee inflow elections and investigate the vote share of the party announced "open-door" policy. Analysis suggests that although refugees and natives are culturally closer than the Western country contexts, small negative effects documented are likely be driven by non-economic reasons. These findings bring a new perspective to understand why anti-immigrant sentiments are easy to use and manipulate.

“Clinical and biological role of adjuvant dendritic cells vaccination in newly glioblastoma patients”

Background. Glioblastoma (GBM) is the most common primary tumor of central nervous system and it has a poor prognosis. Standard first line treatment, which includes surgery followed by adjuvant radio-chemotherapy,produces only modest benefits to survival. The interest for immunotherapy in this field derives from the development of new drugs and effective therapies as immune-check points inhibitors, adoptive T-cell approaches or dendritic cell (DC) based vaccines or a combinations of these. GBM is described as a typical “immune-deserted” cancer exhibiting a number of systemic and environmental immunosuppressive factors. Considering the role of microenvironment, and above all the lower tumor load and depletion of immunosuppressive cells in GBM, our hypothesis is that DC vaccine may induce an immune response. Main aims and study design. The main aim of this project is to study the role of immune system in GBM, including identification of potential prognostic and predictive markers of outcome and response to dendritic cell vaccine. Firstly, we performed a retrospective analysis on blood samples. Then, we analyzed the immuno-component in tissues samples of enrolled patients; and compared that with blood results. Then, the last part of the project is based on a prospective clinical trial on patients enrolled in DC-based vaccination produced at IRST Cell Factory and actually used for patients with melanoma and other tumors. The enrollment is still ongoing. Expected results. The project will i) develop an immune-panel of prognostic and predictive markers to help clinicians to improve the therapeutic strategy for GBM patients; ii) provide preliminary results on the effectiveness of immunotherapy on GBM patients.
