We show that, in repeated common interest games without discounting, strong `perturbation implies efficiency' results require that the perturbations must include strategies which are `draconian' in the sense that they are prepared to punish to the maximum extent possible. Moreover, there is a...

The paper analyzes the Nash equilibria of two-person discounted repeated games with one-sided incomplete information and known own payoffs. If the informed player is arbitrarily patient relative to the uninformed player, then the characterization for the informed player's payoffs is essentially...

The fluctuations in incomes inherent in rural communities can be attenuated by reciprocal assistance. A model of reciprocal assistance based upon rational action and voluntary participation is presented. Individuals provide assistance only if the costs of so doing are outweighed by the benefits...

The arguments put forward by Bulow and Rogoff (1988, 1991) against sovereign debt buybacks are re-examined in a willingness-to-pay framework. This paper argues that the Bulow-Rogoff framework treats default by a debtor as an event with no dead-weight loss, and, as such, underestimates the...

This paper introduces staggered wage contracts a la Taylor (1979)into a standard model of monetary policy credibility. The overlapping wage structure is shown to considerably exacerbate the time consistent inflation rate in Markov perfect equilibrium. If the central bank can commit to its...

This paper considers a two-period optimal contracting model in which firms make new hires in the second period subject to the constraint that they cannot pay discriminate either against or in favor of the new hires. Under an assumption on the information available to workers, it is shown that...

Capital account liberalization and exchange rate regime choice, what scope for flexibility in Tunisia? The adoption by Tunisia of structural reforms of its economy in a context of gradual opening since 1986, had allowed the instauration in January 1993 of the convertibility of its current...

The recent debates over discriminatory versus uniform-price auctions in the UK and elsewhere have revealed an incomplete understanding of the limitations of some popular auction models when applied to real-world electricity markets. This has led certain regulatory authorities to prefer...

In a Bayesian game players play an unknown game. Before the game starts some players may receive a signal regarding the specific game actually played. Typically, information structures that determine different signals, induce different equilibrium payoffs.In zero-sum games the equilibrium payoff...

This paper characterizes interim efficient mechanisms for public good production and cost allocation in a two-type environment with risk neutral, quasi-linear preferences and fixed size projects, where the distribution of the private good, as well as the public goods decision, affects social...
