Methods for Generating Longitudinally Correlated Binary Data

The analysis of longitudinally correlated binary data has attracted considerable attention of late. Since the estimation of parameters in models for such data is based on asymptotic theory, it is necessary to investigate the small‐sample properties of estimators by simulation. In this paper, we review the mechanisms that have been proposed for generating longitudinally correlated binary data. We compare and contrast these models with regard to various features, including computational efficiency, flexibility and the range restrictions that they impose on the longitudinal association parameters. Some extensions to the data generation mechanism originally suggested by Kanter (1975) are proposed.     

Effect of different types of feedback on the level of auditors' configural information processing

Previous audit judgement research has emphasized the importance of auditors processing information configurally (i.e. jointly considering the impact of different cues). This paper examines the impact of four different forms of feedback (outcome, task properties, cognitive and combined) on increasing the extent of configural information processing by auditors. We find that task properties, cognitive and combined (task properties plus cognitive) feedback all lead to increased configural information processing. There is no impact of outcome feedback. We also find that the extent of configural processing is positively associated with our measure of judgement performance. We discuss the implications of the results for audit firms.     

Business Ethics in Transitional Economies: Introduction

This paper introduces the special issue of papers selected from those presented at the International Conference on Business Ethics in Transitional Economies, held March 20–22, 2002 in Celakovice and Prague, Czech Republic. A brief background on the conference is given, and a summary of the papers offered in this special issue is provided.     

ENDOGENOUS PUNISHMENTS IN AGENCY WITH VERIFIABLE EX POST INFORMATION*

The article studies an adverse selection model in which a contractible, imperfect signal on the agent's type is revealed ex post. The agent is wealth constrained, which implies that the maximum penalty depends on the contracted transaction (e.g., the volume of trade). First, we show that the qualitative effects of the signal can be unambiguously tied to the nature of the problem (e.g., whether the agent is in a “buyer” or a “seller” position). Second, the distortions caused by informational asymmetries may become more severe although more information is now available. Finally, the signal can actually serve to increase the agent's informational rents.     

Bertrand–Edgeworth Duopoly with Buyouts or First Refusal Contracts

In this game the players are firms involved in a Bertrand–Edgeworth duopoly market. Payoffs to the low priced firm depend only on the own price, whereas the payoff to the high priced firm depends on both its own price and the price of the opponent. The price of the opponent enters the payoff function of the high priced firm through buyout or a first refusal contract. Only when the total capacity in the market is less than the output in a monopoly situation, there is an equilibrium in pure strategies.Journal of Economic LiteratureClassification Numbers: C72, D43, L12.     

ENDOGENOUS FORMATION OF COMPETITIVE RESEARCH SHARING JOINT VENTURES*

Research sharing is an important objective of many research joint ventures. When partners share R&D but do not maximize joint profits, large consortia are more profitable than small ones, and joint ventures prefer dispersed rivals. For much of the spillover space, a coalition formation game that permits limited membership predicts that at most, three joint ventures form. Research‐sharing joint ventures improve welfare when spillovers are low, and banning research sharing joint ventures is beneficial for high spillovers. With imperfect research sharing and low spillovers, allowing only research sharing is the best industry‐wide joint venture alternative for consumer surplus.
