Knowledge that Transforms

This article presents an empirical study of strike activity in a panel of contract negotiations for some 250 firm-and-union pairs. Evidence is presented on two sources of variation in dispute rates: changes in the characteristics of the collective bargaining agreement that affect subsequent strike outcomes and the effects of lagged strikes on the incidence and duration of subsequent disputes. Strike probabilities are significantly affected by the duration and expiration month of the previous agreement. Dispute rates are also increased by the occurrence of a short strike during the previous negotiations and reduced by the occurrence of a long strike.

This paper considers labor contracts between the risk-neutral firm and risk-averse workers with heterogeneous outside opportunities (alternative wages), which become known to the worker after a costly on-the-job search. In the case of a deterministic alternative wage, self-selection over a menu of contract wages would achieve the first-best contract. If the alternative wages are stochastic, the second-best contract emerges as a trade-off between productive efficiency and risk sharing. Workers who voluntarily search are fewer, and workers who search are less likely to quit. If the search effort is not monitored, even fewer workers search.

The wage differential between men and women is a thorn in the side of economists, theorists and empiricists alike. Theorists are by and large at a loss to explain the persistence of such a wage gap in a competitive environment, and empiricists are hard pressed to identify the factors that explain it.
