This thesis provides a comprehensive analysis of migration’s diverse
impacts across low-income (16 African countries), upper-middle-income
(T¨urkiye), and high-income (the United Kingdom) settings, focusing on
health, political dynamics, and labor market outcomes. Recognizing the
inherent endogeneity and reverse causality in migration studies, this
research employs a range of econometric techniques, including instrumental
variable (IV) methods and two-way fixed effect models, to establish causal
relationships. Chapter 2 investigates the political consequences of
refugee presence in 16 Sub-Saharan African countries, leveraging UNHCR
refugee data and Constituency-Level Elections Archive (CLEA) data, and
finds that inclusive refugee policies enhance incumbent support and reduce
electoral competition by improving access to public services and
stimulating local economies, as evidenced by Afrobarometer survey data.
Chapter 3 examines the health implications of the Syrian refugee influx on
Turkish children under five, utilizing the Turkish Demographic and Health
Survey (TDHS) and an IV approach to address endogenous refugee settlement.
Findings reveal a positive impact on children’s anthropometric measures,
driven by increased maternal time, particularly among low-educated
mothers. Chapter 4 explores the pay-health nexus in the UK, using the
Understanding Society Survey (USS) and a Two-Stage Least Squares (2SLS)
approach to demonstrate that high pay significantly improves physical and
mental health. This chapter also examines the heterogeneous effects of gig
work and multiple job holding on health, using quantile regression, and
analyzes the generational differences in health outcomes among migrant
populations. The thesis highlights the importance of inclusive migration
policies and strategic aid distribution in maximizing positive spillovers
for host communities, while also addressing health inequalities through
improved pay and job conditions. It underscores the need for
context-specific policies that facilitate migrant integration and ensure
equitable outcomes, contributing to a deeper understanding of migration’s
complex socioeconomic impacts.
