After declining from the mid-1970s to the mid-1980s, earnings inequality in Costa Rica stabilized from 1987 to 1992 and then increased from 1992 to 1999. In this paper we use recently-developed techniques to measure the extent to which these changes in earnings inequality were the result of...

In August 2010, the Costa Rican government implemented a comprehensive program to increase compliance with legal minimum wages, the Campaña Nacional de Salarios Mínimos (National Campaign for Minimum Wages). To evaluate the impact of the Campaign, the authors use a regression discontinuity...

We document changes in income and earnings inequality in the five Central American countries from the early 1990s to 2009. In the 1990s Costa Rica had the most equal distribution of income in Central America, and one of the most equal distributions of income in Latin America. At the other...

In August 2010 the Costa Rican government implemented a comprehensive program to increase compliance with legal minimum wages, the Campaign for Minimum Wages. To evaluate the impact of the Campaign, we use a regression discontinuity approach, which compares what happened to workers who before...

This paper investigates the effects of legal minimum wages on wages, employment, hours worked and monthly earnings among workers covered by minimum wage legislation as well as those for whom it does not apply (the uncovered sector) in Costa Rica. This country’s large uncovered sector and...

This paper contributes to our understanding of the impact of institutions on incomes of workers in developing countries by rigorously addressing the question as to whether changes in minimum wages can change the inequality of the distribution of earnings. More specifically, we analyze whether...

The classic dual economy models of developing countries hold minimum wages (among other institutions) accountable for persistent dualism. They note that applying or enforcing minimum wage laws in only one sector of the economy will create wage differentials which will not be eroded with labor...

This paper investigates the effects of legal minimum wages on wages, employment, hours worked and monthly earnings among workers covered by minimum wage legislation as well as those for whom it does not apply (the uncovered sector) in Costa Rica. This country’s large uncovered sector and...
