We show that firms intermediating trade have incentives to overinvest in financial expertise, and that these investments can be destabilizing. Financial expertise in our model improves firms' ability to accurately estimate value when trading a security. It creates adverse selection, which under...

This paper explores the private and social benefits from barter exchange in a monetized economy. We first prove a no-trade theorem regarding the ability of firms with double-coincidences-of-wants to negotiate improvements in trade among themselves relative to the market outcomes. We then...

For a two-period screening model of strikes it is shown that joint bargaining instead of enterprise negotiations lowers wages and implies more strikes. These results hold irrespective of the party possessing private information. The sensitivity of strike models to procedural assumptions thus...

If communication involves some transactions cost to both sender and recipient, what policy ensures that correct messages - those with positive social surplus - get sent? Filters block messages that harm recipients but benefit senders by more than transactions costs. Taxes can block positive...

The paper addresses the mechanism design problem of eliciting truthful information from a committee of informed experts who collude in their information disclosure strategies. It is shown that under fairly general conditions full information disclosure is possible if and only if the induced...

In many auctions, matching between the bidder and seller raises the value of the contract for both parties. However, information about the quality of the match may be incomplete. We consider the case in which each bidder observes the quality of his match with the seller but the seller does not...

This paper studies markets for heterogeneous goods using mechanism-design theory. For each combination of desirable properties, I derive an assignment process with these properties in the form of a corresponding direct-revelation game, or I show that it does not exist. Each participant's utility...

We develop a dynamic model of debt contracts with adverse selection and belief updates. In the model, entrepreneurs borrow investment goods from lenders to run businesses whose returns depend on entrepreneurial productivity and common productivity. Entrepreneurial productivity is the...

In this paper, we propose and analyze a distributed negotiation strategy for a multi-agent multi-attribute negotiation in which the agents have no information about the utility functions of other agents. We analytically prove that, if the zone of agreement is non-empty and the agents concede up...
