BACKGROUND: Internal migration, mostly composed of young adults and the poor, constitutes the largest flow of people in developing countries. Few studies document the patterns and determinants of internal youth migration in sub-Saharan Africa. OBJECTIVES: This paper analyzes the socioeconomic...

We compare a set of econometric studies that measure the effect of net internal migration in neoclassical models of long-run real income convergence and derive 67 comparable effect sizes. The precision-weighted estimate of beta convergence is about 2.7%. An increase in the net migration rate of...

International migration is characterized by two puzzling facts: First, only a small share of the population tends to migrate although substantial and persisting income differences across countries exist. Second, net migration rates tend to cease over time despite persisting income differences....

France experienced the demographic transition before richer and more educated countries. This paper offers a novel explanation for this puzzle that emphasizes the diffusion of culture and information through internal migration. It tests how migration affected fertility by building a decennial...

We examine how low and high skilled internal emigration causally affect investments in human capital at origin. We provide theoretical and empirical evidence of a disincentive mechanism through which individuals refrain from education should low skilled emigration prove a viable alternative. Our...

We follow 3,512 (of 1.4 million) applicants to a government lottery that randomly allocated visas to Bangladeshis for low-skilled, temporary labor contracts in Malaysia. Most lottery winners migrate, and their remittance substantially raises their family's standard of living in Bangladesh. The...

This paper investigates the long-term implications of climate change on local, interregional, and international migration of workers. For nearly all of the world's countries, our micro-founded model jointly endogenizes the effects of changing temperature and sea level on income distribution and...

We develop and estimate a theory-consistent gravity model for interregional migration flows in the presence of unemployment. Micro-founded in a setting where search friction regulates labor market transitions, we derive a migration gravity equation for bilateral mobility that embodies a...

This research suggests that a Darwinian evolution of entrepreneurial spirit played a significant role in the process of economic development and the dynamics of inequality within and across societies. The study argues that entrepreneurial spirit evolved non-monotonically in the course of human...

There is continuing debate about what explains cooperation and self-sacrifice in nature and in particular in humans. This paper suggests a new way to think about this famous problem. I argue that, for an evolutionary biologist as well as a quantitative social scientist, the triangle of two...
