We evaluate the determinants of matching efficiency changes through a stochastic Cobb- Douglas production frontier model extended to allow the efficiency coefficient to depend on variables meant to capture workers and firms characteristics. We apply this methodology to examine regional...

Using a stochastic frontier approach this paper evaluates the effects of substantial changes in the teaching material on students learning efficiency. The results indicate that the main effects of the re-organization on the learning efficiency was a decreasing importance of students' attendance...

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...

A standard hidden information model is considered to study the influence of the a priori productivity distribution on the optimal contract. A priori more productive (hazard rate dominant) agents work less, enjoy lower rents, but generate a higher expected surplus.

In this paper we exploit the longitudinal element of the 1990 and 1998 Workplace Employee Relations Surveys for Britain to investigate the effect of unionism on establishment closings. Contrary to both recent U.S. research and British work using information from the earlier workplace surveys, we...

Social norms are usually neglected in economics, because they are to a large extent enforced through non-market interactions and difficult to isolate empirically. In this paper, we offer a direct measure of the social norm to work and we show that this norm has important economic effects. The...
