Economists are often puzzled by the stronger public opposition to immigration than trade, since the two policies have similar effects on wages. Unlike trade, however, immigration can alter the composition of the local population, imposing potential externalities on natives. While previous...

How do ethnic religious organizations influence immigrants' assimilation in host societies? This paper offers the first systematic answer to this question by focusing on Italian Catholic churches in the US between 1890 and 1920, when four million Italians moved to America, and anti-Catholic...

The literature on immigrant assimilation and intergenerational progress has sometimes reached surprising conclusions, such as the puzzle of immigrant advantage which finds that Hispanic immigrants sometimes have better health than U.S.-born Hispanics. While numerous studies have attempted to...

We use a population resettlement program in Indonesia to identify long-run effects of intergroup contact on national integration. In the 1980s, the government relocated two million ethnically diverse migrants into hundreds of new communities. We find greater integration in fractionalized...

I study the selection and economic outcomes of Italians in Argentina and the US, the two largest destinations during the age of mass migration. Prior cross-sectional work finds that Italians had faster assimilation in Argentina, but it is inconclusive on whether this was due to differences in...

Whether immigrants advance in labor markets relative to natives as they gain experience is a fundamental question in the economics of immigration. For the US, it has been difficult to answer this question for the period when the immigration rate was at its historical peak, between the 1840s and...

The repeated failure of Ireland's potato crop in the late 1840s led to a major famine and a surge in migration to the US. We build a dataset of Irish immigrants and their sons by linking males from 1850 to 1880 US census records. For comparison, we also link German and British immigrants, their...

Using 2004-2008 data from the American Time Use Survey, we show that sharp differences between the time use of immigrants and natives become noticeable when activities are distinguished by incidence and intensity. We develop a theory of the process of assimilation--what immigrants do with their...

This paper reviews the recent evidence on U.S. immigration, focusing on two key questions: (1) Does immigration reduce the labor market opportunities of less-skilled natives? (2) Have immigrants who arrived after the 1965 Immigration Reform Act successfully assimilated? Looking across major...

The national origin of an individual's human capital is a crucial determinant of its value. Education acquired abroad is significantly less valued than education obtained domestically. This difference can fully explain the earnings disadvantage of immigrants relative to comparable natives in...
