We investigate learning at the workplace. To do so, we use German administrative data that contain information on the entire workforce of a sample of establishments. We document that having more highly paid coworkers is strongly associated with future wage growth, particularly if those workers...

Machines increasingly replace people in routine job tasks. The remaining tasks require workers to make open-ended decisions and to have "soft" skills such as problem-solving, critical thinking and adaptability. This paper documents growing demand for decision-making and explores the consequences...

We develop a tractable general equilibrium model for understanding within- and between-occupation changes in skill use over time. We apply the model to skill-use measures from the third, fourth, and revised fourth editions of the Dictionary of Occupational Titles and data from the 1960, 1970,...

We look at how the arrival of an invention affects wage returns and probability of moving out of employment for white- and blue-collar coworkers of the inventor. First results suggest that older workers are hurt by the arrival of an invention. This negative effect disappears when we control for...

We investigate the impact of computerization of white-collar jobs on wages and employment. Using online job postings from 2007 and 2010--2016 for office and administrative support (OAS) jobs, we show that when firms adopt new software at the job-title level they increase the skills required of...

The law prohibits firms from moving work to avoid unionization. Still, many employees fear that joining a union may cost them their jobs. This paper assesses the impact of that fear on how clerical workers vote in union certification elections. Two data sets were collected and analyzed for this...

We examine the effect of hearing cases alongside female judicial colleagues on the probability that a federal judge hires a female law clerk. Federal judges are assigned to cases and to judicial panels at random and have few limitations on their choices of law clerks: these two features make the...

The nullification of slave wealth after the U.S. Civil War (1861-65) was one of the largest episodes of wealth compressions in history. We document that white Southern households holding more slave assets in 1860 lost substantially more wealth by 1870, relative to households that had been...

We model network formation in a firm. Agents learn about the quality of their working relationships with each other. Their good relationships become their networks. Accumulating relationships becomes increasingly costly, however. Over time agents become less open to forming relationships with...

Cyclical patterns in earnings can arise when contracts between firms and their workers are incomplete, and when workers cannot borrow or lend so as to smooth their consumption. Earnings cycles generate occasional large changes in earnings, consistent with some recent empirical findings. At the...
