Self-selection among undocumented immigrants from Mexico
This paper examines the effect of changes in migration determinants on the skill level of undocumented immigrants from Mexico. We focus on the effect of changes in economic conditions, migrant networks, and border enforcement on the educational attainment of Mexican-born men who cross the border illegally. Although previous research indicates that illegal aliens from Mexico tend to be unskilled relative to US natives and that economic conditions, networks and border enforcement affect the size of illegal immigrant flows across the border, the interaction of these variables has not been ...

The Postpandemic U.S. Immigration Surge: New Facts and Inflationary Implications
The U.S. experienced an extraordinary postpandemic surge in unauthorized immigration. This paper combines administrative data on border encounters and immigration court records with household survey data to document two new facts about these immigrants: They tend to be hand-to-mouth consumers and low-skilled workers that complement the existing workforce. We build these features into a model with capital, household heterogeneity and population growth to study the inflationary effects of this episode. Contrary to the popular view, we find little effect on inflation, as the increase in supply ...

Firm Heterogeneity and the Impact of Immigration: Evidence from German Establishments
We use a detailed establishment-level dataset from Germany to document a new dimension of firm heterogeneity: large firms spend a higher share of their wage bill on immigrants than small firms. We show analytically that ignoring this heterogeneity in the immigrant share leads to biased estimates of the welfare gains from immigration. To do so, we set up and estimate a model where heterogeneous firms choose their immigrant share and then use it to quantify the welfare effects of an increase in the number of immigrants in Germany. Two new adjustment mechanisms arise under firm ...

Immigrant language barriers and house prices
Are language skills important in explaining the nexus between house prices and immigrant inflows? The language barrier hypothesis says immigrants from a non common language country value amenities more than immigrants from common language countries.> ; In turn, immigrants from non common language countries are less price sensitive to house price changes than immigrants from a common language country. Tests of the language barrier hypothesis with Swiss house prices show that an immigration inflow from a non common language country equal to 1 percent of an area's population is coincident with ...

Slowdown in Immigration, Labor Shortages, and Declining Skill Premia
We document a slowdown in low-skilled immigration that began around the onset of the Great Recession in 2007, which was associated with a subsequent rise in low-skilled wages, a decline in the skill premium, and labor shortages in service occupations. Falling returns to education also coincided with a decline in the educational attainment of native workers. We then develop and estimate a stochastic growth model with endogenous immigration and training to rationalize these facts. Lower immigration leads to higher wages for low-skilled workers but also to higher consumer prices and lower ...

Diversification and specialization of U.S. states
This paper documents the evolution of the international relationships of individual U.S. states along three dimensions: trade, migration, and finance. We examine how specialized or diversified state economies differ in terms of the products they export and with whom they trade, the origins of the immigrants who live in the state, and the origins of the foreign banks operating in the state. We show that states that are diversified along one of these dimensions are often quite specialized along others. New York is?perhaps, not surprisingly?the most diversified state in terms of global linkages.

The Well-Being of Nations: Estimating Welfare from International Migration
The limitations of GDP as a measure of welfare are well known. We propose a new method of estimating the well-being of nations. Using gross bilateral international migration flows and a discrete choice model in which everyone in the world chooses a country in which to live, we estimate each country?s overall quality of life. Our estimates, by relying on revealed preference, complement previous estimates of economic well-being that consider only income or a small number of factors, or rely on structural assumptions about how these factors contribute to wellbeing.

Skilled Immigration Frictions as a Barrier for Young Firms
This paper studies the impact of skilled immigration policy frictions in the United States on technology-intensive firms by age cohorts. We use firm-level data and a general equilibrium model with endogenous firm entry and exit. The empirical results show that skilled immigration policy frictions directly influence young firm dynamics in technology-intensive sectors by affecting firm survival. Our general equilibrium model incorporates skilled foreign labor and immigration policy frictions that mimic the H-1B policy and matches the age distribution of firms in high-technology sectors, showing ...

Offshoring, Low-skilled Immigration, and Labor Market Polarization
During the last three decades, the U.S. labor market has been characterized by its employment polarization. As jobs in the middle of the skill distribution have shrunk, employment has expanded in high- and low-skill occupations. Real wages have not followed the same pattern. While earnings for high-skill occupations have risen robustly, wages for both low- and middle-skill workers have remained subdued. We attribute this outcome to the rise in offshoring and low-skilled immigration, and develop a three-country stochastic growth model to rationalize their asymmetric effect on employment and ...
