This paper studies insurance arrangements in village economies when there is complete information but limited commitment. Commitment is limited because only limited penalties can be imposed on households which renege on their promises. Any efficient insurance arrangements must therefore take...

This paper considers the regulated monopoly that pads or falsifies its costs to increase the cost reimbursement it receives from the regulator. Contrary to the standard literature on cost regulation, the firm engages in cost reducing investment before it enters into a regulatory contract. This...

This paper considers a simple stochastic model of international trade with three countries. Two of the tree countries are in an economic union. Comparisons are made between equilibrium welfare for these two countries under fixed and flexible exchange rate regimes. Within the model it is shown...

This paper considers whether countries might mutually agree a policy of allowing free movement of workers. For the countries to agree, the short run costs must outweighed by the long term benefits that result from better labor market flexibility and income smoothing. We show that such policies...

either above or below the efficient level and that actions and the division of the surplus converges to a stationary solution at which either both investment levels are efficient or both are below the efficient level.

Rationing is a pervasive feature of credit markets. It has been suggested that credit rationing represents a suboptimal allocation of resources. In a general equilibrium model of credit rationing with hidden information and costly monitoring we show that if credit is rationed it is suboptimal...

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...

This paper analyses a model of private unemployment insurance under limited commitment and a model of public unemployment insurance subject to moral hazard in an economy with a continuum of agents and an infinite time horizon. The dynamic and steady-state properties of the private unemployment...
