This paper examines the impact of individual human operators on the fuel efficiency of power plants. Although electricity generation is a fuel and capital intensive enterprise, anecdotal evidence, interviews, and empirical analysis support the hypothesis that labor, particularly power plant...

This paper studies simple partial equilibrium models of dynamic labor demand, under certainty. Labor turnover costs may or may not decrease the firm's average labor demand, depending on the form of the revenue function, on the rates of discount and of labor attrition, and on the relative size of...

We adopt a general equilibrium approach in order to measure the effects of recent immigration on the Western German labor market, looking at both wage and employment effects. Using the Regional File of the IAB Employment Subsample for the period 1987-2001, we find that the substantial...

In this paper, we survey non-competitive theories of training. With competitive labor markets, firms never pay for investments in general training, whereas when labor markets are imperfect, firm-sponsored training arises as an equilibrium phenomenon. We discuss a variety of evidence which...

Starting in 1985, (West) German unions began to reduce standard hours on an industry by industry basis, in an attempt to lower unemployment. Whether work-sharing works - whether employment rises when hours per worker are reduced - is theoretically ambiguous. I test this using both individual...

This paper presents a semiparametric procedure to analyze the effects of institutional and labor market factors on recent changes in the U.S. distribution of wages. The effects of these factors are estimated by applying kernel density methods to appropriately 'reweighted' samples. The procedure...
