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...

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...

During the Age of Mass Migration (1850-1913), the US maintained an open border, absorbing 30 million European immigrants. Prior cross-sectional work on this era finds that immigrants initially held lower-paid occupations than natives but experienced rapid convergence over time. In...

We compile large datasets from Norwegian and US historical censuses to study return migration during the Age of Mass Migration (1850-1913). Return migrants were somewhat negatively selected from the migrant pool: Norwegian immigrants who returned to Norway held slightly lower-paid occupations...

The authors explore unique complete-count data from the 1930 Census in which a respondent's race was assigned by enumerators and "Mexican" was one of the possible responses. Census enumerators frequently and selectively assigned a non-Mexican race--predominantly "white"--to U.S.-born individuals...

The United States has admitted more than 3 million refugees since 1980 through official refugee resettlement programs. Scholars attribute the success of refugee groups to governmental programs on assimilation and integration. Before 1948, however, refugees arrived without formal selection...

The inflow of refugees and their subsequent integration can be an important challenge for both the refugees themselves and the host society. Policy interventions can improve the lives and economic success of refugees and of their communities. In this paper, we review the socioeconomic...

What makes diversity unifying in some settings but divisive in others? We examine how the mixing of ethnic groups in German schools affects intergroup cooperation and trust. We leverage the quasi-random assignment of students to classrooms within schools to obtain variation in the type of...

How does previous exposure to massive immigrant inflows affect concerns about current immigration and the integration of refugees? To answer this question, we investigate attitudes toward newcomers among natives and previous immigrants. In areas that in the 1990s received higher inflows of...
