This paper evaluates performance of human subjects and instances of a bidding model that interact in continuous-time double auction experiments. Asks submitted by instances of the seller model ("automated sellers") maximize the seller's expected surplus relative to a heuristic belief function,...

In spite of fiat money is useless in a standard Arrow-Debreu model, in this paper we will show that this does not hold true anymore when goods are indivisible. In our setting, although fiat money yields no utility, its price will always be positive and the set of equilibrium allocations changes...

Introducing default and limited collateral into general equilibrium allows for a theoery of endogenous contracts, ..

Does the Pareto criterion discriminate among policy choices when the policymaker does not know the correct model of the economy? If the policymaker can specify ex ante preferences for each agent, there will typically be some policy change that improves the welfare of each agent relative to a...

We take the view that alternative trading opportunities may influence the loss to delay in a bargaining situation, and show that contractual exclusivity may then be relevant even for ‘internal’ investments, contradicting a recent finding by Segal and Whinston (2000). When a buyer is an...

This paper considers the ``negotiation game'' Busch and Wen (1995)) which combines the features of two-person alternating offers bargaining and repeated games. Despite the forces of bargaining, the negotiation game in general admits a large number of equilibria some of which involve delay and...

We consider a two-sided, finite-horizon search and matching model with heterogeneous types and complementarity between types. The quality of the pool of potential partners deteriorates as agents who have found mutually agreeable matches exit the market. When search is costless and all agents...

This paper investigates the interaction between education decisions by workers and investment decisions by firms in a random matching model with endogenous heterogeneity. I analyze the efficiency properties of the equilibrium and find that in the presence of search frictions and investment costs...

Consider the case of a firm with private valuation information bargaining with a supplier over the price and quantity of a good. If the firm and the supplier bargain directly, the bargaining outcome may not yield a first-best outcome due to the presence of information rents. The question we...

This paper develops a search-theoretic model of the cross-sectional distribution of asset returns. It abstracts from risk premia and focuses exclusively on liquidity. A float-adjusted return model (FARM) is derived, explaining the pricing of liquidity with a simple linear formula: In...
