We describe the construction of a panel data set from the U.S. patent data that contains measures of inventors' life-cycle R&D productivity--patents and patent citations. We match the data set to information on the U.S. pharmaceutical and semiconductor firms for whom they work. In this paper we...

I investigate why workers' probability of leaving unemployment has fallen since 1900 by estimating the impact of a large government transfer, the first major pension program in the United States, covering Union Army veterans of the Civil War. The pension, because of the program's rules, was a...

We study the evolution of individual labor earnings over the life cycle using a large panel data set of earnings histories drawn from U.S. administrative records. Using fully nonparametric methods, our analysis reaches two broad conclusions. First, earnings shocks display substantial deviations...

“Multigenerational mobility” refers to the associations in socioeconomic status across three or more generations. This article begins by summarizing the longstanding but recently growing empirical literature on multigenerational mobility. It then discusses multiple theoretical...

In this paper, we develop a gender-specific crosswalk based on dual-coded Current Population Survey data to bridge the change in the Census occupational coding system that occurred in 2000 and use it to provide the first analysis of the trends in occupational segregation by sex for the 1970-2009...

Federal and state employment programs for low-skilled workers typically emphasize rapid placement of participants into jobs and often place a large fraction of participants into temporary-help agency jobs. Using unique administrative data from Detroit's welfare-to-work program, we apply the...

Concerns over the impacts of hospital strikes on patient welfare led to substantial delay in the ability of hospitals to unionize. Once allowed, hospitals unionized rapidly and now represent one of the largest union sectors of the U.S. economy. Were the original fears of harmful hospital strikes...

The growing education and employment of women are usually cited as crucial forces behind the decline of marriage since 1960. However, both trends were already present between 1900 and 1960, during which time marriage became increasingly widespread. This early period differed from the post-1960...

I use the 1993 and 2003 National Surveys of College Graduates to examine the higher exit rate of women compared to men from science and engineering relative to other fields. I find that the higher relative exit rate is driven by engineering rather than science, and show that 60% of the gap can...
