We consider collective choice from two alternatives. Ex-ante, each agent is uncertain about which alternative she prefers, and may be uncertain about the intensity of her preferences. An environment is given by a probability distribution over utility vectors that is symmetric across agents and...

In the basic adverse selection model, a seller makes a contract offer to a privately informed buyer. A fundamental hypothesis of incentive theory is that the seller may want to offer a menu of contracts to separate the buyer types. In the good state of nature, total surplus is not different from...

There are many commodities that possess the characteristic of non-rivalness in consumption even though exclusion is possible. The focus of this paper is the optimal contract designed by a profit-maximizing monopolist, who can provide an excludable public good to a group of n potential consumers,...

Private information of the agent about his valuation may either decrease or increase his investment incentives, depending on whether he learns his type...
