Morally motivated individuals behave more cooperatively than predicted by standard theory. Hence,if a firm can attract workers who are strongly motivated by ethical concerns, moral hazard problems like shirking can be reduced. We show that employers may be able to use the firm’s corporate...

This paper studies the aggregate distribution of declared opinions and behavior when heterogeneous individuals make the trade-off between being true to their private opinions and conforming to an endogenous social norm. The model sheds light on how various punishment regimes induce conformity or...

To secure their membership in a popular group, individuals may contribute more to the group’s local public good than they would if group formation were exogenous. Those in the most unpopular group do not have this incentive to contribute to their group. Substantial differences in individual...

Many empirical studies find a partial negative effect of market integration on cooperation in traditional poor small-scale farmer communities in developing countries, blaming an erosion of collective action enhancing norms (Social Capital). This paper takes the empirical analysis one step...

Unreported labour by one worker in a firm increases the probability of detection for his fellow workers, not only for himself. The firm takes this external effect into account. As a consequence, unreported work becomes rationed by the firms demand, rather than determined by demand equal supply....

This paper discusses aspects of a framework for modeling labor supply where the notion of job choice is fundamental. In this framework, workers are assumed to have preferences over latent job opportunities belonging to worker-specific choice sets from which they choose their preferred job. The...

Recently Dagsvik and Karlström (2005) have demonstrated how one can compute Compensating Variation and Compensated Choice Probabilities by means of analytic formulas in the context of discrete choice models. In this paper we offer a new and simplified derivation of the Compensated probabilities...

A longitudinal analysis of married physicians labor supply is carried out on Norwegian data from 1997 to 1999. The model utilized for estimation implies that physicians can choose among 10 different job packages which are a combination of part time/full time, hospital/primary care,...

We estimate a dynamic discrete choice model of Registered Nurses’ labor supply with random terms. A distinguished feature of our model is that random terms are correlated over time and jobs (habit persistence). Past options and not only the past optimal choices matter for the current choices....

A crucial issue in efficiency-equality evaluations of tax reforms resides in the possibility that the level as well as the distribution of welfare may change, where the household-specific measures of welfare capture the value of income as well as the value of leisure. A better-designed...
