Rethinking the Effect of Immigration on Wages

This paper estimates the effects of immigration on wages of native workers at the national U.S. level. Following We emphasize that a production function framework is needed to combine workers of different skills in order to evaluate the competition as well as cross-skill complementary effects of immigrants on wages. We also emphasize the importance (and estimate the value) of the elasticity of substitution between workers with at most a high school degree and those without one. Since the two groups turn out to be close substitutes, this strongly dilutes the effects of competition between immigrants and workers with no degree. We then estimate the substitutability between natives and immigrants and we find a small but significant degree of imperfect substitution which further decreases the competitive effect of immigrants. Finally, we account for the short run and long run adjustment of capital in response to immigration. Using our estimates and Census data we find that immigration (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006) had small negative effects in the short run on native workers with no high school degree (-0.7%) and on average wages (-0.4%) while it had small positive effects on native workers with no high school degree (+0.3%) and on average native wages (+0.6%) in the long run. These results are perfectly in line with the estimated aggregate elasticities in the labor literature since We also find a wage effect of new immigrants on previous immigrants in the order of negative 6%.

Immigration and National Wages: Clarifying the Theory and the Empirics

Do Immigrants Affect Firm-Specific Wages?

This paper provides an approximation to the labor market effects of immigrants in Spain, a country where labor market institutions and immigration policy exhibit some peculiarities, during the second half of the 1990s, the period in which immigration flows accelerated. By using alternative data sets, we estimate both the impact of legal and total immigration flows on the employment rates and wages of native workers, accounting for the possible occupational and geographical mobility of immigrants and native-born workers. Using different samples and estimation procedures, we have not found a significant negative effect of immigration on either the employment rates or wages of native workers.

Using data from the Current Population Survey, we study the impact of the increasing proportion of immigrants on the wages of native workers. Two different approaches are contrasted. The most common method has been the spatial approach that uses some geographic unit of analysis to investigate the multivariate association between the proportion of immigrants and the wages of native workers. Previous studies using the spatial approach have generally found little evidence of a significant negative effect. We propose, however, a contrasting method that represents an occupational approach in which occupations are the unit of analysis to investigate the impact of the proportion immigrant. This occupational approach avoids the bias that is inherent in the spatial approach due to the endogenous nature of immigrants' decisions about where to reside and the economic opportunities of local areas. In contrast to the spatial approach, our results using the same data but employing the occupational approach yield consistently negative net effects of the proportion immigrant on the wages of native workers during the period from 1994 to 2006.

This paper analyses the effect immigration has on wages of native workers. Unlike most previous work, we estimate wage effects along the distribution of wages. We derive a flexible empirical strategy that does not rely on pre-allocating immigrants to particular skill groups. In our empirical analysis, we demonstrate that immigrants downgrade considerably upon arrival. As for the effects on native wages, we find that immigration depresses wages below the 20th percentile of the wage distribution, but leads to slight wage increases in the upper part of the wage distribution. The overall wage effect of immigration is slightly positive. The positive wage effects we find are, although modest, too large to be explained by an immigration surplus. We suggest alternative explanations, based on the idea that immigrants are paid less than the value of what they contribute to production, generating therefore a surplus, and we assess the magnitude of these effects.

We propose and test a novel effect of immigration on wages. Existing studies have focused on the wage effects that result from changes in the aggregate labour supply in a competitive labour market. We argue that if labour markets are not fully competitive, immigrants might also affect wage formation at the most disaggregate level – the workplace. Using linked employer−employee data, we find that an increased use of low‐skilled immigrant workers has a significantly negative effect on the wages of native workers at the workplace – also when controlling for potential endogeneity of the immigrant share using both fixed effects and instrumental variables.

This paper asks the following question: what was the effect of surging immigration on average and individual wages of U.S.-born workers during the period 1990-2004? We emphasize the need for a general equilibrium approach to analyze this problem. The impact of immigrants on wages of U.S.-born workers can be evaluated only by accounting carefully for labor market and capital market interactions in production. Using such a general equilibrium approach we estimate that immigrants are imperfect substitutes for U.S.-born workers within the same education-experience-gender group (because they choose different occupations and have different skills). Moreover, accounting for a reasonable speed of adjustment of physical capital we show that most of the wage effects of immigration accrue to native workers within a decade. These two facts imply a positive and significant effect of the 1990-2004 immigration on the average wage of U.S.-born workers overall, both in the short run and in the long run. This positive effect results from averaging a positive effect on wages of U.S.-born workers with at least a high school degree and a small negative effect on wages of U.S.-born workers with no high school degree.

Immigration, Endogenous Technology Adoption and Wages

We analyze the impact of recent immigration on the employment and wages of less educated workers during the 1990s, a period of heightened geographic diffusion of immigrants across the nation. We focus on men residing in metropolitan areas, who are between the ages of 25 and 62 and are from the three major racial/ ethnic groups: white non-Hispanic, black nonHispanic, and Latino (hereafter referred to as race groups). Theory predicts that immigration will increase the wages of native workers who are complements to immigrants and decrease the wages of natives who are substitutes. Because immigrants have low education relative to natives, low-educated natives are likely to be substitutes, and high-educated natives are likely to be complements. We find negative effects of recent immigration on the employment, and especially the wages, of low-skilled workers. The wage effects are largest for Latinos, followed by blacks.
