The Effects of Multiple Minimum Wages Throughout the Labor Market

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 complex minimum wage policy, which has for decades set numerous wages throughout the wage distribution, provide a stimulating counterpoint to the U.S. framework for the analysis of the impact of minimum wages. We find that legal minimum wages have a significant positive effect on the wages of workers in the covered sector (with an elasticity of 0.10) but no effect on wages of workers in the uncovered sector. We also find that a 10% increase in minimum wages lowers employment in the covered sector by 1.09% and decreases the average number of hours worked of those who remain in the covered sector by about 0.6%. Finally, we show that despite the wide range of minimum wages, the largest impact on the wages and employment of covered sector workers is in the lower half of the distribution.http://deepblue.lib.umich.edu/bitstream/2027.42/40087/3/wp701.pd

Minimum Wages, Inequality and Globalization

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 changes in Costa Rica’s complex institution of multiple minimum wages in the 1980s and 1990s acted as a countervailing force to the unequalizing effect of globalization. Using annual data on workers from the 1987-1997 household surveys, it is shown that changes in the legal minimum wages did indeed have an effect on wage inequality and that these changes would not have been captured using the simple interpretation of minimum wages found in much of the literature.http://deepblue.lib.umich.edu/bitstream/2027.42/40086/3/wp700.pd

Legal Minimum Wages and the Wages of Formal and Informal Sector Workers in Costa Rica

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 mobility to the high wage sector. In this paper we use 12 years of micro data on thousands workers living in Costa Rica to test whether legal minimum wages have a differential impact on the wages of workers in the formal sector vs. informal sector, defined in various ways in accordance with the dual development models. The evidence from Costa Rica is contrary to the assumptions of these models. We find that increases in minimum wages not only raise the wages of workers in the urban formal sector (large urban enterprises) who are covered by minimum wage law, but they also increase the wages of all other workers covered by minimum wage legislation in what are traditionally regarded as informal sectors and where the legislation is often considered not to be enforced. Specifically, we provide evidence that minimum wages increase the wages of workers in small urban enterprises, large rural enterprises and small rural enterprises. Further, our results suggest that higher legal minimum wages raise the average wage of workers in these “informal” sectors more than in the urban formal sector. We concluded that in Costa Rica minimum wages are being enforced in the rural and small scale sectors and may actually work to reduce average wage differentials between these sectors and the urban formal sector. On the other hand, minimum wages have no significant impact on the wages of workers in another sector that is regarded as informal but which is not covered by minimum wage legislation: the self-employed workers (both urban and rural). Thus, one could argue that minimum wages may contribute to dualism between the formal and informal, defined as self-employed vs. salaried workers. However, we find no evidence of the bleaker scenario, that self-employed earnings are being lowered by minimum wages.http://deepblue.lib.umich.edu/bitstream/2027.42/40033/3/wp647.pd

South-South Migration: The Impact of Nicaraguan Immigrants on Earnings, Inequality and Poverty in Costa Rica

More than half of those who emigrate from developing countries move to other developing countries, yet there have been few studies of the impact of this South-South migration. In this paper, we examine the impact of migration from one developing country, Nicaragua, on the labor market in another developing country, Costa Rica. We find little evidence to support the hypothesis that Nicaraguan migration to Costa Rica was an important factor contributing to falling earnings, increased inequality or stagnating poverty in Costa Rica.Costa Rica, earnings, Latin America, migration, inequality, poverty

Are Hispanic Immigrant Families Reviving the Economies of America's Small Towns?

In the 1990s, rural areas and small towns in the United States, which had been losing population, became the destinations for an increasing number of Hispanic immigrants and their families, slowing and in some cases reversing population declines. In this paper, we examine whether faster growth in the Hispanic population is linked to faster growth in income per capita in rural areas and small towns. Our results indicate strong support for the hypothesis that Hispanic population growth has fueled increased economic growth in those small, rural communities whose populations had been in decline during the 1970s and 1980s.regional economic growth, Hispanics, migration

Accounting for Changing Inequality in Costa Rica, 1980-1999

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 changes associated with the distributions (or .quantities.) of personal and work place characteristics of workers, and the earnings differences (or .prices.) associated with those characteristics. We present evidence that the most important cause of the fall in inequality prior to 1987 was a decline in returns to education, which in turn was caused by an increase in the supply of more-educated workers. We find that the most important causes of rising inequality in the 1990s were the end of this decline in returns to education and increases in the variance of hours worked among workers. Inequality in hours worked increased because of an increase in the proportion of workers working a non-standard work week (part-time or over-time)inequality, Latin America, labor
