This paper models how migration both influences and responds to differences in disease prevalence between cities, regions and countries, and show how the possibility of migration away from high-prevalence areas affects long-run steady state disease prevalence. We develop a dynamic framework...

This paper explores implications of the fact that individuals know more than the authorities about their risk of infection and can take migration decisions before their health status is publicly observable. In a 2-period model we study under which conditions the presence of quarantine measures...

We study food Engel curves among the poor population targeted by a conditional cash transfer programme in Colombia. After controlling for the endogeneity of total expenditure and for the (unobserved) variability of prices across villages, the best fit is provided by a log-linear specification....

A significant gap exists in the UK between the employment rate for Ethnic Minorities and that for Whites. From a policy perspective, it is important to know whether this gap is due to differences in the characteristics of White and Ethnic Minority groups (which reduce the employability of Ethnic...

The paper studies the effects of Familias en Acción, a conditional cash transfer programme implemented in rural areas in Colombia in 2002, on school enrolment and child labour. Using a quasi-experimental approach, our methodology makes use of an interesting feature of the data, which allows us...

The extent of entrepreneurial activity in an economy with poorly developed capital markets depends on the distribution of wealth, though in potentially complex ways. A non-parametric model of the wealth effect on self-employment is estimated using micro data on the occupational choices of return...

This paper investigates how the permanent departure of the head from the household, mainly due to death or divorce, affects children’s school enrolment and work participation in rural Colombia. In our empirical specification we use household-level fixed effects to deal with the fact that...

This paper provides evidence on household responses to the relaxation of one barrier constraining adoption of health practices - lack of information - in a resource constrained setting. It examines the effects of a randomized intervention in Malawi which provides mothers with information on...

Guest-worker programs have been providing rapidly growing economies with millions of temporary foreign workers over the last couple of decades. With the duration of stay strictly limited by program rules in most of the host countries and wages paid to guest workers often set at sub-market...

We study how smugglers respond to different types of migration policies - legalisation through the sale of migration visas, or more traditional repressive policies through borders' enforcement, employers' sanctions or deportation - by changing the price they propose to illegal migrants. In this...
