We examine a dynamic model of mutual insurance when households can also engage in self insurance by storage. We assume that there is no enforcement mechanism, so that any insurance is informal, and must be self-enforcing. We show that consumption allocations satisfy a modified Euler condition...

In this paper we analyse a model in which firms cannot pay discriminate based on year of entry to the firm, and argue that the wage dynamics are consistent with the empirical results of Beaudry and DiNardo (1991). Their results have been interpreted as supporting a model in which workers are ex...

Rigidity in real hiring wages plays a crucial role in some recent macroeconomic models. But are hiring wages really so noncyclical? We propose using employer/employee longitudinal data to track the cyclical variation in the wages paid to workers newly hired into specific entry jobs. Illustrating...

This paper analyses a model in which firms cannot pay discriminate based on year of entry. It is assumed that workers can costlessly quit at any time, while firms are committed to contracts. We solve for the dynamics of wages and unemployment, and show that real wages display a degree of...

We study optimal punishment in an all-pay contest with endogenous entry, where the participant with the lowest performance may be punished. When a small punishment is introduced, the lowest ability players drop out and those of medium ability exert less effort, while only the highest ability...
