We explore how umpires' racial/ethnic preferences are expressed in their evaluation of Major League Baseball pitchers. Controlling for umpire, pitcher, batter and catcher fixed effects and many other factors, strikes are more likely to be called if the umpire and pitcher match race/ethnicity....

Taking as our point of departure a model proposed by David Card (2001), we suggest new methods for analyzing wage dispersion in a partially unionized labor market. Card's method disaggregates the labor population into skill categories, which procedure entails some loss of information....

Job mobility, especially early in a career, is an important source of wage growth. This effect is typically attributed to heterogeneity in the quality of employee-employer matches, with individuals learning of their abilities and discovering the tasks at which they are most productive through...

Although the adverse labor market effects of economic recessions have been well documented, a notable omission in the literature is how recessions impact workers' job match quality. This paper considers the short and longer-term losses in productivity associated with the job changing brought in...

This paper uses matched employee-employer LIAB data to provide panel estimates of the structure of labor demand in Germany, 1993-2002, distinguishing between highly skilled, skilled, and unskilled labor and between the manufacturing and service sectors. Reflecting current preoccupations, our...

Just as the standard two-way fixed effects model for estimating the impact of minimum wages on employment has been sharply criticized for its neglect of spatial heterogeneity so, too, have the latest models been attacked for their uncritical use of state- or county-specific linear trends (and...

At first blush, most advances in labour demand were achieved by the late 1980s. Since then progress might appear to have stalled. We argue to the contrary that significant progress has been made in understanding labour market frictions and imperfections, and in modelling search behaviour and...

Using time-diary data from 25 countries, we demonstrate that there is a negative relationship between real GDP per capita and the female-male difference in total work time per day - the sum of work for pay and work at home. In rich northern countries on four continents, including the United...

This study examines the potential impact of works councils and unions on the deployment of fixed-term contracts and agency temps. We report inter al. that works councils are associated with a higher number of temporary agency workers when demand volatility is high while the opposite holds for...

H. Gregg Lewis did fundamental research outlining the economic effects of trade unions and considering how to measure them carefully. He also laid out the theory of the supply and demand for labor in careful detail that has underlain economists' thinking about these outcomes. Aside from...
