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...

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 shows that linking a sufficiently large number of independent but unrelated social decisions can achieve approximate efficiency. We provide regularity conditions under which a Groves mechanism amended with a veto game implements an efficient outcome with probability arbitrarily close...

Commodity bundling is studied in an environment where the dispersion of valuations unambiguously decreases when two or more goods are sold as a bundle only. Bundling is more likely to dominate separately selling the goods if marginal costs are low relative to the average valuation, or if the...

Comparing monopoly bundling with separate sales is relatively straightforward in an environment with a large number of goods. In this paper we show that results that are similar to the asymptotic results can be obtained in the more realistic case with a given finite number of goods provided that...

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...

We consider an environment with asymmetric information about preferences for a public good and a private good. If the public good must be financed from contributions made by participants and if participants must be given incentives to participate in the mechanism, we show that there are...
