I study the question of how much product information should be available to consumers. A monopolist sells one unit of product. The consumer is initially uninformed of the product value but can incur costs to observe a noisy signal of his valuation. I show that consumer surplus can be increasing...

Consider an investment problem with strategic complementarities and incomplete information about returns. This paper shows that investors aggregate their private information in equilibrium by trading a token and observing its market price over multiple rounds before making the investment...

We study a general static noisy rational expectations model, where investors have private information about asset payoffs, with common and private components, and about their own exposure to an aggregate risk factor, and derive conditions for existence and uniqueness (or multiplicity) of...

This paper studies information aggregation in financial markets with recurrent investor exit and entry. I consider a dynamic general equilibrium model of asset trading with private information and collateral constraints. Investors differ in their aversion to Knightian uncertainty: When...

We present an experiment that models a repeated public good provision setting where the policy maker or manager does not have perfect control over information flows. Rather, information seeking can be affected by changing the information default as well as the price of information. The default...

This paper studies "voluntary bargaining agreements" in an environment where preferences over an excludable public good are private information. Unlike the case with a non-excludable public good, there are non-trivial conditions when there is significant provision in a large economy. The...

We examine the private provision of a public good whose level is determined by the least contribution of individual group members. Nash equilibrium can be efficient when the game is one of full information. This paper introduces private information about the costs of effort and characterizes...

Consider two parties who can make non-contractible investments in the provision of a public good. Who should own the physical assets needed to provide the public good? In the literature it has been argued that the party who values the public good most should be the owner, regardless of the...

We propose a novel proportional cost-sharing mechanism for funding public goods with interdependent values: the agents simultaneously submit bids, which are non-negative numbers; the expenditure on the public good is an increasing and concave function of the sum of the bids; and each agent is...
