This paper compares the wage of a worker performing an activity for an outside contractor with the wage that the firm contracting for this service would have paid were this worker on its payroll (i.e., working in-house).

This paper provides the first experimental evidence on the effect of increased competition on the prices and quality of goods. We rely on an intervention that randomized the entry of 61 retail firms (grocery stores) into 72 local markets in the context of a conditional cash transfer program that...

Total factor productivity (TFP) in Latin America has not increased since the mid- 1970s, and in many countries it has declined. Moreover, resource misallocation can lower aggregate TFP. This paper presents evidence based on firm-level data from 10 Latin American countries to quantify the...

We use 292 household surveys from 18 Latin American countries to document patterns in secondary school graduation rates over the period 1990-2010. We find that enrollment and graduation rates increased during that period while dropout rates decreased. We provide two types of explanations for...

The laws that regulate relations between firms and workers in Mexico distinguish sharply between salaried and non-salaried workers, and they are at the root of the existence of informality. This paper provides a clear definition of informality, distinguishing it from illegality. Using Mexico’s...
