Working Paper
On Regional Borrowing, Default, and Migration
Migration plays a key role in city finances with every new entrant reducing debt per person and every exit increasing it. We study the interactions between regional borrowing, migration, and default from empirical, theoretical, and quantitative perspectives. Empirically, we document that in-migration rates are positively correlated with deficits, that many cities appear to be at or near state-imposed borrowing limits, and that defaults can occur after booms or busts in productivity and population. Theoretically, we show that migration creates an externality that results in over-borrowing, and ...

High-Skill Migration, Multinational Companies, and the Location of Economic Activity
This paper examines the relationship between high-skill immigration and multinational activity. I assemble a novel firm-level dataset on high-skill visa applications and show that there is a large home-bias effect. Foreign multinational enterprises (MNEs) in the US tend to hire more migrant workers from their home countries compared to US firms. To quantify the general equilibrium implications for production and welfare, I build and estimate a quantitative model that includes trade, MNE production, and the migration decisions of high-skill workers. I use an instrumental variables approach to ...

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 ...

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 impact of migration on earnings inequality
This paper examines the impact of migration on earnings inequality using 1940?2015 data from the U.S. census and American Community Survey. Despite measurement challenges, I successfully replicate existing findings regarding national trends in earnings inequality and migration, and subsequently analyze regional and state patterns. Using 1940 birthplace information to instrument for migration, I find that recent immigration mildly increases the top decile earnings share, while recent in-migration and out-migration have no significant effects on such inequality. I estimate that immigration ...

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.

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 ...
Working Paper
Unauthorized Immigration and Fiscal Competition
Reflecting upon recent enforcement policy activism of US states and countries within the EU towards unauthorized workers, we examine the overlap of centralized (federal) and decentralized (state or regional) enforcement of immigration policies in a spatial context. Among other results, we find that if interstate mobility is costless, internal enforcement is overprovided, and border enforcement and local goods are underprovided when regions take more responsibility in deciding policies. This leads to higher levels of unauthorized immigration under decentralization. Interregional migration ...

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.
