This paper characterizes interim efficient mechanisms for public good production and cost allocation in a two-type environment with risk-neutral, quasi-linear preferences and fixed-size projects, where the distribution of the private good, as well as the public goods decision, affects social...

This paper identifies several social-choice correspondences which are or are not fully implementable in economic environments when agents are incompletely informed about the environment. The authors show that in contrast to results in the case of complete information, neither efficient...

The authors study the problem of implementing social choice correspondences via Nash equilibrium in which no one uses a weakly dominated strategy. The main result is that if there are at least three agents in society, then any correspondence that satisfies no veto power is implementable unless...
