In an interconnected world, national economic policies regularly lead to large international spillover effects, which frequently trigger calls for international policy cooperation. However, the premise of successful cooperation is that there is a Pareto inefficiency, i.e. if there is scope to...

We study the Rothschild-Stiglitz model of competitive insurance markets with endogenous information disclosure by both firms and consumers. We show that an equilibrium always exists, (even without the single crossing property), and characterize the unique equilibrium allocation. With two types...

This paper describes an efficiency approach to the evaluation of policy changes. Rather than comparing the utility allocations that arise before and after a policy change is introduced, this approach evaluates a policy change by comparing it with other possible changes which might be made from...

This paper argues that campaign finance policy, in the form of contribution limits and matching public financing, can be Pareto improving even under the most optimistic assumptions concerning the role of campaign advertising and the rationality of voters. The argument assumes that candidates use...

This paper studies an Overlapping Generations model with stochastic production and incomplete markets to assess whether the introduction of an unfunded social security system can lead to a Pareto improvement. When returns to capital and wages are imperfectly correlated, the consumption variance...
