We bring to bear a novel dataset covering the employment history of about 450 million individuals from 180 countries to study return migration and the impact of skilled international migration on human capital stocks across countries. Return migration is a common phenomenon, with 38% of skilled...

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...

As firms have more assets in place, more of management's limited attention is focused on managing assets in place rather than developing new growth options. Consequently, as firms grow older, they have fewer growth options and a lower ability to generate new growth options. This simple theory...

OECD governments note rising immigration with alarm and grapple with policies aimed at selecting certain migrants and keeping out others. Economists appear to be well armed to advise governments since they are responsible for an impressive literature that examines the characteristics of...

Recent theoretical and empirical studies have emphasized the fact that the prospect of international migration increases the expected returns to skills in poor countries, linking the possibility of migrating (brain drain) with incentives to higher education (brain gain). If emigration is...

Getting science policy right is a core objective of government that bears on scientific advance, economic growth, health, and longevity. Yet the process of science is changing. As science advances and knowledge accumulates, ensuing generations of innovators spend longer in training and become...

Two great movie directors were both born in 1930. One of them, Jean-Luc Godard, revolutionized filmmaking during his 30s, and declined in creativity thereafter. In contrast, Clint Eastwood did not direct his first movie until he had passed the age of 40, and did not emerge as an important...

The information content of academic citations is subject to debate. This paper views premature death as a tragic "natural experiment," outlining a methodology identifying the "citation death tax" -- the impact of death of productive economists on the patterns of their citations. We rely on a...

We find that alcoholism decreases labor force participation among prime age males, and therefore decreases the income of this group. The effects of alcoholism on the labor force participation of younger and older males and on the wage rates of prime age males are not significantly positive. We...

We systematically review the literature linking health to economic activity, particularly education and labor market outcomes, over the lifecycle. In the first part, we review studies that link childhood health to later-life outcomes. The main themes we focus on are in-utero exposures,...
