In this paper, we document the importance of high-skilled immigration for U.S. employment in STEM fields. To begin, we review patterns of U.S. employment in STEM occupations among workers with at least a college degree. These patterns mirror the cycle of boom and bust in the U.S. technology...

In this paper, we use data from the Mexico and U.S. population censuses to examine who migrates from Mexico to the United States and how the skills and economic performance of these individuals compare to those who remain in Mexico. We test Borjas' negative-selection hypothesis that in poor...

In this paper, I selectively review recent literature on illegal migration from Mexico to the United States. I begin by discussing methods for estimating stocks and flows of illegal migrants. While there is uncertainty about the size of the unauthorized population, new data sources make it...

Recent literature on the labor-market effects of U.S. immigration tends to find little correlation between regional immigrant inflows and changes in relative regional wages. In this paper we examine whether immigration, or endowment shocks more generally, altered U.S. regional output mixes as...

From the 1970s to the early 2000s, the United States experienced an epochal wave of low-skilled immigration. Since the Great Recession, however, U.S. borders have become a far less active place when it comes to the net arrival of foreign workers. The number of undocumented immigrants has...

How will worldwide changes in population affect pressures for international migration in the future? We contrast the past three decades, during which population pressures contributed to substantial labor flows from neighboring countries into the United States and Europe, with the coming three...

Even before the Great Recession, U.S. employment growth was unimpressive. Between 2000 and 2007, the economy gave back the considerable gains in employment rates it had achieved during the 1990s, with major contractions in manufacturing employment being a prime contributor to the slump. The U.S....

An increasingly influential "technological-discontinuity" paradigm suggests that IT-induced technological changes are rapidly raising productivity while making workers redundant. This paper explores the evidence for this view among the IT-using U.S. manufacturing industries. There is some...
