In incomplete information environments with transferable utility, efficient outcomes are generally implementable unless interim or ex post participation constraints are imposed on the problem. In this paper we show that linking a sufficiently large number of independent but possibly unrelated...

This paper studies the optimal provision mechanism for multiple excludable public goods when agents\' valuations are private information. For a parametric class of problems with binary valuations, we characterize the optimal mechanism, and show that it involves bundling. Bundling alleviates the...

We provide a simple proof of the equivalence between ex ante and ex post budget balance constraints in Bayesian mechanism design with independent types when participation decisions are made at the interim stage. The result is given an interpretation in terms of efficient allocation of risk.

This paper studies the optimal provision mechanism for multiple excludable public goods. For a class of problems with symmetric goods and binary valuations, we show that the optimal mechanism involves bundling if a regularity condition, akin to a hazard rate condition, on the distribution of...

Public provision of a private goods is justified on efficiency grounds in a model with no redistributive preferences. A government’s involvement in the provision of a private good generates information about preferences that facilitates more efficient revenue extraction for the provision of...

This paper shows that public provision of private goods may be justified on pure efficiency grounds in an environment where individuals consume both public and private goods. The government's involvement in the provision of private goods provides it with information about individuals' private...

the private good improves economic efficiency under a condition that is always fulfilled under stochastic independence and satisfied for an open set of joint distributions. Our model is an example where there is an efficiency loss from separating revenue and expenditure problems, and is...
