We study how an optimal income tax and an optimal public-goods provision rule respond to preference and productivity shocks. A conventional Mirrleesian treatment is shown to provoke manipulations of the policy mechanism by individuals with similar interests. We therefore extend the Mirrleesian...

We develop a dynamic model of political competition. Each party has a policymotivated ideological wing and an office-motivated opportunistic wing. A blockade arises if inner-party conflict stops policy implementation. We use this model to study whether early elections should be used to overcome...

We characterize the Pareto-frontier in a simple Mirrleesian model of income taxation. We show how the second-best frontier which incorporates incentive constraints due to private information on productive abilities relates to the first-best frontier which takes only resource constraints into...

We propose a new approach to the normative analysis of public-good provision. In addition to individual incentive compatibility, we impose conditions of robust implementability and coalition proofness. Under these additional conditions, participants' contributions can only depend on the level of...

We study the relation between mechanism design and voting in public-good provision. If incentive mechanisms must satisfy conditions of coalition-proofness and robustness, as well as individual incentive compatibility, the participants' contributions to public-good provision can only depend on...

Gerrymandering undermines representative democracy by creating many uncompetitive legislative districts, and generating the very real possibility that a party that wins a clear majority of the popular vote does not win a majority of districts. We present a new approach to the determination of...
