Throughout the postwar era until 1995 labor productivity grew faster in Europe than in the United States. Since 1995, productivity growth in the EU-15 has slowed while that in the United States has accelerated. But Europe's productivity growth slowdown was largely offset by faster growth in...

There are two obvious possibilities that can account for the rise in productivity during recent recessions. The first is that the decline in the workforce was not random, and that the average worker was of higher quality during the recession than in the preceding period. The second is that each...

Job losses during the Great Recession were concentrated among middle-skill workers, the same group that over the long run has suffered the most from automation and international trade. How might long-run occupational polarization be related to cyclical changes in middle-skill employment? We find...

Do robots raise or lower economic well-being? On the one hand, they raise output and bring more goods and services into reach. On the other hand, they eliminate jobs, shift investments away from machines that complement labor, lower wages, and immiserize workers who cannot compete. The net...

This paper compares the impact of new IT-enhanced technology on the efficiency of production in the U.S. and the U.K. for one manufacturing industry, valve manufacturing. There is a long-standing question of whether technological change and organizational changes have the same rates of adoption...

Will smart machines replace humans like the internal combustion engine replaced horses? If so, can putting people out of work, or at least out of good work, also put the economy out of business? Our model says yes. Under the right conditions, more supply produces, over time, less demand as the...

A central organizing framework of the voluminous recent literature studying changes in the returns to skills and the evolution of earnings inequality is what we refer to as the canonical model, which elegantly and powerfully operationalizes the supply and demand for skills by assuming two...

How would people spend time if confronted by permanent declines in market work? We identify preferences off exogenous cuts in legislated standard hours that raised employers' overtime costs in Japan around 1990 and Korea in the early 2000s. We estimate the probability that an individual was...

In search and bargaining models, the effect of higher wages on employment is determined by the elasticity of the job creation curve. In this paper, we use U.S. data over the 1970-2007 period to explore whether labor market outcomes abide by the restrictions implied by such models and to evaluate...

We consider a matching model of employment with wages that are flexible for new hires, but sticky within matches. We depart from standard treatments of sticky wages by allowing effort to respond to the wage being too high or low. Shimer (2004) and others have illustrated that employment in the...
