“Go North! Unintended Consequences on Science and Invention”
Abstract: One hundred years ago, the United States first established a nationality-based quota system to keep out “subversives” and other types of “undesirable” immigrants. National origins quotas under the Immigration Act of 1924 were especially successful at dramatically reducing inflows from Eastern and Southern Europe, while continuing to allow immigration from Western and Northern Europe. Using unique data on the exact birth date, place, date, and education of more than 80,000 scientists, we examine the unintended effects of these quotas on immigrant scientists in Canada and the United States. Exploiting information on the precise age of scientists, we construct high-quality matches between scientists and their US patents. Using scientist-level patents we investigate whether changes in migration caused persistent changes in patterns of invention between Canada and the United States.
