Assessing the impact of lead exposure is difficult if individuals select on the basis of their characteristics into environments with different exposure levels. We address this issue with data from when the dangers of lead exposure were still largely unknown, using new evidence on intelligence...

The link between circumstances faced by individuals early in life (including those encountered in utero) and later life outcomes has been of increasing interest since the work of Barker in the 1970s on birth weight and adult disease. We provide such a life course perspective for the U.S. by...

This paper examines the evolution of the Mexican-born workforce in the United States using data drawn from the decennial U.S. Census throughout the entire 20th century. It is well known that there has been a rapid rise in Mexican immigration to the United States in recent years. Interestingly,...

Within the conceptual framework of the Roy model, this paper provides an empirical analysis of internal migration flows using data from the National Longitudinal Surveys of Youth. The theoretical approach highlights regional differences in the returns to skills: regions that pay higher returns...

The U.S. both tolerates more inequality than Europe and believes its economic mobility is greater than Europe's. These attitudes and beliefs help account for differences in the magnitude of redistribution through taxation and social welfare spending. In fact, the U.S. and Europe had roughly...

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...

Immigrants who arrived in the U.S. before the Civil War were less likely to reside in locations with high immigrant concentrations as their time in the U.S. increased. This is contrary to the experience of recent immigrants who show no decrease in concentration after arrival. The reduced...

This study examines the occupational mobility of antebellum immigrants as they entered the U.S. White collar, skilled, and semi-skilled immigrants left unskilled jobs more rapidly after arrival than farmers and unskilled workers. British and German immigrants fared better than the Irish;...

The origins of American exceptionalism þ the apolitical nature of American labor unions compared to their European counterparts þ have puzzled labor historians. Recently, the hypothesis has been advanced that organized labor abandoned attempts to win reform through legislation because the...
