In May 1981, President François Mitterrand regularized the status of undocumented immigrant workers in France. The newly legalized immigrants represented 12 percent of the non-French workforce and about 1 percent of all workers. Employers have monopsony power over undocumented workers because...

Natives benefit from immigration mainly because of production complementarities between immigrant workers and other factors of production, and these benefits are larger when immigrants are sufficiently `different' from the stock of native productive inputs. The available evidence suggests that...

Over 12 million persons migrated to Canada or the United States between 1959 and 1981. Beginning in the mid?1960s, the immigration policies of the two countries began to diverge considerably: the United States stressing family reunification and Canada stressing skills. This paper shows that the...

Self-selection plays a dominant role in determining the size and composition of immigrant flows. The United States competes with other potential host countries in the "immigration market". Host countries vary in their "offers" of economic opportunities and also differ in the way they ration...

Self-employment is an important aspect of the immigrant experience in the labor market. Self-employment rates for immigrants exceed 15 percent for some national groups. This paper addresses three related questions on the self-employment experience of immigrants. First, how do self-employment...

Employment rates in the United States fell dramatically between February 2020 and April 2020 as the repercussions of the COVID-19 pandemic reverberated through the labor market. This paper uses data from the CPS Basic Monthly Files to document that the employment decline was particularly severe...

In this paper, we simulate the long-run effects of migrant flows on wages of high-skilled and low-skilled non-migrants in a set of countries using an aggregate model of national economies. New in this literature we calculate the wage effect of emigration as well as immigration. We focus on...

Although economic theory predicts an inverse relation between relative wages and immigration-induced supply shifts, it has been difficult to document such effects. The weak evidence may be partly due to sampling error in a commonly used measure of the supply shift, the immigrant share of the...
