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...

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...

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

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...

Admati and Perry (1987) derive the equilibrium in a bargaining game between a seller and buyer when the buyer's valuation is private information. They show that, for some parameter values, trade occurs at the Rubinstein (1982) prices given the buyer's true valuation (pl if the buyer has a low...

In this paper, we develop a search-based model of asset trading. We assume that investors differ in their horizons, and can invest in two identical assets. The asset markets are partially segmented: investors can search in only one market, but can decide which one. We show that there exist a...

This work introduces a rigorous set-theoretic foundation of bilateral matching mechanisms and studies their properties in a systematic manner. By providing a unified framework to study ilateral matching mechanisms, we formalize how different spatial/informational constraints can be implemented...

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...
