We estimate the effect of immigrant flows on native employment in Western Europe, and then ask whether the employment consequences of immigration vary with institutions that affect labor market flexibility. Reduced flexibility may protect natives from immigrant competition in the near term, but...

Natural and agricultural resources for which there is a substantial black market, such as coca, opium, and diamonds, appear especially likely to be exploited by the parties to a civil conflict. Even legally traded commodities such as oil and timber have been linked to civil war. On the other...

Reduced labour market flexibility may protect some native workers from immigrant competition but can increase negative effects on equilibrium employment. This motivates an analysis of immigration effects interacted with institutions. OLS estimates for European countries show small, mostly...

We study the consequences of an exogenous upsurge in coca prices and cultivation in Colombia, where most coca leaf is now harvested. This shift generated only modest economic gains in rural areas, primarily in the form of increased self-employment earnings and increased labor supply by teenage...

Many schools have recently experimented with moving breakfast from the cafeteria to the classroom. We examine whether such a program increases achievement, grades, and attendance rates. We exploit quasi‐random timing of program implementation that allows for a difference‐in‐differences...

Using data from nationally representative household surveys, we test whether Indian parents make trade-offs between the number of children and investments in education and health of their children. To address the endogeneity due to the joint determination of quantity and quality of children by...

In 1990 Colombia replaced its traditional system of severance payments with a new system of severance payments savings accounts (SPSAs). Although severance payments often are justified on the grounds that they provide insurance against earnings loss, they also increase costs for employers and...

In response to low take-up, many public schools have experimented with moving breakfast from the cafeteria to the classroom. We examine whether such a program increases performance as measured by standardized test scores, grades and attendance rates. We exploit quasi-random timing of program...
