We analyze the infinitely repeated prisoners' dilemma with imperfect private monitoring and discounting. The main contribution of this paper is to construct ``belief-based'' strategies, where a player's continuation strategy is a function only of his beliefs. This simplifies the analysis...

We study and compare law enforcement costs under two alternative burden of proof rules with the objective of reducing crime to a target level. We show that presuming innocence rather than guilt has a cost advantage, mainly due to lower costs of preventing collusion between law enforcers and...

How should a principal delegate a task to an agent? This paper studies the choice of an agent's discretion as a contracting problem. We show that the agent's freedom of action can be used as an effective incentive device: the agent's initiative is determined by the discretion he has in decision...

The literature on relational incentive contracts suggests that firms may be able to condition payments to employees on information that is not available to those outside the firm. Given this, market participants may use the magnitude of such payments to infer the non-public information, which...

We report on a novel forecasting method based on nonlinear Markov modelling and canonical variate analysis, and investigate the use of a prediction algorithm to forecast conditional volatility. In particular, we assess the dynamic behaviour of the model by forecasting exchange rate volatility....

This paper presents a monetary policy game where firms' and wage setters' choices are derived explcitly from microfoundations. This approach allows us to relate some important features of the policy game to identifiable technological and preference parameters. Moreover, it shows that with large...

The demand for gasoline follows a seasonal cycle in Sweden. The paper investigates the response in prices and profits over the cycle. In contrast to what has been found for the gasoline market in the United States I find no support for seasonal price changes compatible with the recently...
