Increasing wage inequality between similar workers plays an important role for overall inequality trends in industrialized societies. To analyze this pattern, we incorporate directed labor market search into a dynamic model of international trade with heterogeneous firms and homogeneous workers....

This paper develops a new framework for examining the distributional consequences of international trade that incorporates firm and worker heterogeneity, search and matching frictions in the labor market, and screening of workers by firms. Larger firms pay higher wages and exporters pay higher...

We study the effect of 'globalization' on wage inequality. Our 'global' economy resembles Rosen's (1981) 'Superstars' economy, where a) innovations in production and communication technologies enable suppliers to reach a larger mass of consumers and to improve the (perceived) quality of their...

This Paper presents a model in which boundedly rational members of an administrative staff calculate resource allocations in real time. We consider a class of hierarchical procedures in which information about payoff functions flows up and is aggregated by a hierarchy, while allocations flow...

This paper studies an agency framework in which a principal hires a supervisor to monitor the agent's productive effort. We consider several monitoring technologies which differ in the quantity (frequency) and the quality (accuracy) of the information they deliver. We show that the frequency of...

We study how banks should protect their credit departments against the external influence from potential borrowers. We analyze four mechanisms that are widespread in practice: a credit board with unanimity or simple majority, a hierarchy and an advisory system. A bank faces a trade-off between...

This paper studies gender interactions within hierarchical organizations using a large data set on the duration of Italian municipal governments elected between 1993 and 2003. A municipal government can be viewed as a hierarchy, whose stability over time depends on the degree of cooperation...
