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

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.minimum wages, employment, wages, Costa Rica

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.dual economy, informal sector, minimum wages, wages, Costa Rica, Latin America

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

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.minimum wages, employment, wages, Costa Rica

Single Mothers and Poverty in Costa Rica

Despite increasing average real family incomes in Costa Rica in the late 1990s and early 2000s, poverty rates did not fall. In this paper, we argue that during this period economic growth in Costa Rica did not translate into reduced poverty because of changes in family structure and in the labor market, and that these changes had an important gender dimension. Specifically, an increase in the proportion of Costa Rican households headed by single mothers led to an increase in the number of women with children entering the labor force. Many of these mothers, new entrants to the labor force, were unable or unwilling to find full-time work in the high-paying formal sector, and ended up unemployed or working part-time as self-employed workers. These labor market phenomena, in turn, contributed to low incomes for households vulnerable to poverty, especially those households headed by single mothers.wages, Central America, poverty, employment, single mothers, Costa Rica

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

The Effect of Family Separation and Reunification on the Educational Success of Immigrant Children in the United States

For many immigrants, especially those from Central America and Mexico, it is common for a mother or father (or both) to migrate to the United States and leave their children behind. Then, after the parent(s) have achieved some degree of stability in the United States, the children follow. Using qualitative and quantitative methods, we examined the hypothesis that separation during migration results in problems at school after re-unification. We find that children separated from parents during migration are more likely to be behind others their age in school and are more likely to drop out of high school.immigrant children, education, family separation

LA DESIGUALDAD EN AMÉRICA CENTRAL DURANTE LOS AÑOS NOVENTA

Este trabajo pretende examinar dos preguntas: ¿cómo y por qué cambió la distribución de los ingresos en los países de América Central en los años noventa?, y, ¿por qué están los ingresos distribuido en una manera más equitativa en Costa Rica en comparación a los otros países de la región?. Para buscar respuestas a estas preguntas, se usa una técnica, basada en la estimación de ecuaciones de remuneración, que mide la magnitud de la desigualdad debido a diferentes características personales y del puesto de trabajo. La dirección de los cambios en la desigualdad del ingreso en los países Centroamericanos en los años noventa no es clara. Solamente Costa Rica presenta un deterioro claro en la distribución del ingreso. En los otros países, los resultados dependen de la medida de la desigualdad y del preceptor que se utilice. Pero bajo de estos cambios brutos, se encuentran fenómenos comunes en todos los países en los mercados de trabajo. El aumento en la dispersión de las jornadas de trabajo, es el fenómeno que se identifica con el mayor impacto negativo sobre equidad. Se identifican dos causas importantes de los diferentes niveles de desigualdad entre Costa Rica y el resto de los países de América Central. Primero, la educación está más igualitariamente distribuida en Costa Rica que en el resto de la región. Segundo, las diferencias salariales entre las zonas urbanas y rurales son más bajas en Costa Rica. Estos resultados implican que las políticas Costarricenses de la universalización de la educación primaria y de proveer aún a las comunidades rurales más aisladas de infraestructura económica y social son también causas importantes de las diferencias n la desigualdad entre Costa Rica y el resto de Centroamérica.inequality, Latin America, labor

The Impact of Minimum Wages on Wages, Work and Poverty in Nicaragua

We use an individual-level panel data set to study the impact of changes in legal minimum wages on a host of labor market outcomes in Nicaragua including: a) wages and employment, b) transitions of workers across jobs (in the covered and uncovered sectors) and employment status (unemployment and out of the labor force), and c) transitions into and out of poverty. We find that changes in the legal minimum wage affect only those workers whose initial wage (before the change in minimum wages) is close to the minimum. For example, increases in the legal minimum wage lead to significant increases in the wages and decreases in employment of private covered sector workers who have wages within 20% of the minimum wage before the change, but have no significant impact on wages in other parts of the distribution. The estimates from the employment transition equations suggest that the decrease in covered private sector employment is due to a combination of layoffs and reductions in hiring. Most workers who lose their jobs in the covered private sector as a result of higher legal minimum wages leave the labor force or go into unpaid family work; a smaller proportion find work in the public sector. Our analysis of the relationship between the minimum wage and household income finds: a) increases in legal minimum wages increase the probability that a poor worker's family will move out of poverty, and b) increases in legal minimum wages are more likely to reduce the incidence of poverty if they impact the head of the household rather than the non-head.poverty, minimum wages, employment
