Using a stochastic general equilibrium model with overlapping generations, this paper studies (i) the effects on both extensive and intensive labor supply responses to changes in fertility rates, and (ii) the potential of a retirement reform to mitigate the effects of fertility changes on labor...

This paper develops a link between four central components of the demographic transition: survival rates; fertility decisions; altruistic intergenerational transfers from workers toward their parents; and economic growth. An increase in child survival is found to reduce the fertility rate and...

This paper analyzes the macroeconomic implications of population aging in Brazil. Three alternative yet complementary methodologies are adopted, and depending on policy responses to the fiscal implications of aging, there are two main findings: First, saving rates could increase and not...

Extension services are a keystone of information diffusion in agriculture. This paper exploits a large randomized controlled trial to track diffusion of a new technique in the classic Training and Visit (T&V) extension model, relative to a more direct training model. In both control and...

Although child mortality rates have declined all across the developing world over the past 40 years, they have declined the most in the Middle East and North Africa region. This paper documents this remarkable experience and shows that it is broad based in the sense that all countries in the...

Female labor participation in the Arab world is low compared with the level of economic development of Arab countries. Beyond anecdotal evidence and cross-country studies, there is little evidence on what could explain this phenomenon. This paper uses the richest set of panel data available for...

An accurate measurement of HIV incidence is a key for policy makers and HIV program managers directing national HIV response. However, there is no perfect method to measure or estimate the rate at which new HIV infections occur in a population. This review compiles and triangulates longitudinal...

Using bilateral migration flow data from the 2010 population census of Nepal, this paper provides evidence on the importance of public infrastructure and services in determining migration flows. The empirical specification, based on a generalized nested logit model, corrects for the non-random...

This paper develops a dynamic model that explains the pattern of population and production allocation in an economy with an urban location and a rural one. Agglomeration economies make urban dwellers benefit from a larger population living in the city and urban firms become more productive when...
