This paper studies the welfare effects of encouraging rural-urban migration in the developing world. To do so, we build a dynamic incomplete-markets model of migration in which heterogenous agents face seasonal income fluctuations, stochastic income shocks, and disutility of migration that...

A large literature following Ruhm (2000) suggests that mortality falls during recessions and rises during booms. The panel-data approach used to generate these results assumes that either there is no substantial migration response to temporary changes in local economic conditions, or that any...

How integrated are labor markets within a country? Labor mobility is key to the integration of local labor markets and therefore to understanding the efficacy of policies to reduce regional inequality. We present a comprehensive framework for understanding migration decisions, focusing on the...

The direct benefits of infrastructure in developing countries can be large, but if new infrastructure induces in-migration, congestion of other local publicly provided goods may offset the direct benefits. Using the example of rural household electrification in South Africa, we demonstrate the...

Observing rapid structural transformation accompanied by a continual process of rural to urban migration in many developing countries, we construct a micro founded dynamic framework to explore how important education-based migration is, as opposed to work-based migration, for economic...

Do new migration opportunities for rural households change the nature and extent of informal risk sharing? We experimentally document that randomly offering poor rural households subsidies to migrate leads to a 40% improvement in risk sharing in their villages. Our model of endogenous migration...

We develop a stylized EU-type model of a union consisting of rich, capital-abundant and high productivity countries, and poor, capital-scarce and low productivity countries. We address two main issues: the efficiency of tax competition and the effect of factor mobility on the size of the welfare...

Do poor economies grow faster than rich ones? This important economic question (which we call [beta]-convergence) is analyzed in this paper using two regional data sets: 47 Prefectures in Japan and 48 States of the U.S.. We find clear evidence of convergence in both countries: poor prefectures...
