We analyze the behavior of game-show contestants who play a one-shot game called Friend or Foe. While it is a weakly dominant strategy not to cooperate, almost half the contestants on the show choose to play friend.' Remarkably, the behavior of contestants remains unchanged even when stakes are...

This paper describes regularities in the intraday spreads and prices quoted by dealers on the London Stock Exchange. It develops a measure of spread-related transaction costs, one that recognizes dealers' willingness to price trades within their quoted spreads. This measure of transaction costs...

This paper analyzes R&D policies when the returns to cost-reducing and demand-creating R&D are imperfectly appropriable and market structure is endogenous. Previous characterizations of appropriability are generalized to permit the possibility that own and rival R&D are imperfect substitutes. We...

This paper develops and compares nonnested hypothesis tests for linear regression models with first-order serially correlated errors. It extends the nonnested testing procedures of Pesaran, Fisher and McAleer, and Davidson and MacKinnon, and compares their performance on four conventional models...

This article uses unique data from the London Stock Exchange to examine how trader anonymity and market liquidity affect dealers' decisions about where to place interdealer trades. During our sample period, dealers could trade with each other in the direct, nonanonymous public market or use one...

When retail dealers carry only one product line, the size of the dealer margin is crucial in the success of both the manufacturer and the dealer. This article proposes a successive monopoly model of patterns in exclusive dealer and manufacturer margins across a product line. The predictions of...

We use unique data from the London Stock Exchange to test whether interdealer trade facilitates inventory risk sharing among dealers. We develop a methodology that focuses on periods of "extreme" inventories-inventory cycles. We further distinguish between inventory cycles that are unanticipated...

This chapter explains the logic of structural econometric models and compares them to other types of econometric models. We provide a framework researchers can use to develop and evaluate structural econometric models. This framework pays particular attention to describing different sources of...
