In the empirical literature on assortative matching using linked employer-employee data, unobserved worker quality appears to be "negatively" correlated with unobserved firm quality. We show that this can be caused by standard estimation error. We develop formulae that show that the estimated...

Recent policy debate in Europe suggests that a shorter workweek will lead to more jobs (worksharing). We derive and estimate a model where the firm employs two types of workers, some working overtime, the rest standard hours. Worksharing is not always a prediction of the theory. Using German...

Limited Mobility Bias explains why positive assortative matching is not observed in the empirical literature. Using German social security records, we estimate the correlation between worker and firm contributions to wage equations and find that it is unambiguously positive.

"We investigate the impact of financial participation (profit-sharing and share ownership) on workers' total compensation. Some workers' representatives have argued against the introduction of profit-sharing because they fear that profit-sharing would be a way for firms to reduce the marginal...

The effect of standard hours on the hourly wage rate is important in assessing whether work-sharing is likely to be a successful policy. Furthermore, it determines whether unions have achieved their goal of keeping the monthly income of employees constant after a cut in standard hours (income...
