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...

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...

In this paper, we present a matching model with adverse selection that explains why flows into and out of unemployment are much lower in Europe compared to North America, while employment-to-employment flows are similar in the two continents. In the model, firms use discretion in terms of whom...

Re-licensing requirements for professionals that move across borders are widespread. In this paper, we measure the returns to an occupational license using novel data on Soviet trained physicians that immigrated to Israel. An immigrant re-training assignment rule used by the Israel Ministry of...

Many workers believe that personal contacts are crucial for obtaining jobs in high-wage sectors. On the other hand, firms in high-wage sectors report using employee referrals because they help provide screening and monitoring of new employees. This paper develops a matching model that can...

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...

Theory predicts that mandated employment protections may reduce productivity by distorting production choices. Firms facing (non-Coasean) worker dismissal costs will curtail hiring below efficient levels and retain unproductive workers, both of which should affect productivity. These theoretical...

This paper evaluates the impact of a randomized training program for disadvantaged youth introduced in Colombia in 2005. This randomized trial offers a unique opportunity to examine the impact of training in developing countries. We use originally collected data on individuals randomly offered...

We use a panel of manufacturing plants from Colombia to analyze how the rise in payroll tax rates over the 1980?s and 1990?s affected the labor market. Our estimates indicate that formal wages fall by between 1.4% and 2.3% as a result of a 10% rise in payroll taxes. This...
