A century ago, and for most of the twentieth century, Ireland was a land of emigration, not immigration. However, in the space of less than a decade in the 2000s, Ireland was transformed from a homogeneous community, where nonnative residents were in a very small minority, to one in which...

Given the huge size, relatively speaking, of the human influx into Ireland over the past decade or so, the evolution of Irish attitudes to immigration is of more than parochial interest. In this paper we use the six rounds of the European Social Survey (2002-2012) in seeking to account for those...

We examine the effect of changes in skilled-immigrant population shares in 98 Canadian cities between 1981 and 2006 on per capita patents. The Canadian case is of interest because its 'points system' for selecting immigrants is viewed as a model of skilled immigration policy. Our estimates...

We describe a new dataset created from the first 18,000 savings accounts opened (from 1850 to 1858) at the Emigrant Industrial Savings Bank in New York City. The bank was founded by Irish Americans and most of its depositors in its first decade of operations were recent Irish immigrants. The...

In the 2015 refugee crisis, nearly one million refugees came to Germany, raising concern that crimes against natives would rise. Using novel county-level data, we study this question empirically in first-difference and 2SLS regressions. Our results do not support the view that Germans were...

Automated census linkage algorithms have become popular for generating longitudinal data on social mobility, especially for immigrants and their children. But what if these algorithms are particularly bad at tracking immigrants? Using nineteenth-century Irish immigrants as a test case, we...

I study the impact of Canada's expansive immigration policy launched in 2016 on labour shortages in six regions of the country, particularly in Quebec, which enjoys some autonomy of management in this area. I look at movements of the Beveridge curve, which draws the classical inverse relation...
