Summary. Combining a strategy model, an inference procedure and a new experimental design, we map sequences of observed actions in repeated games to unobserved strategies that reflect decision-makers’ plans. We demonstrate the method by studying two institutional settings with distinct theoretical predictions. We find that almost all strategies inferred are best responses to one of the inferred strategies of other players, and in one of the settings almost all of the inferred strategies, which include triggers to punish non-cooperators, are consistent with equilibrium strategies. By developing a method to infer unobserved repeated-game strategies from actions, we take a step toward making game theory a more applied tool, bridging a gap between theory and observed behavior.Received: 23 December 2002, Revised: 19 April 2005, JEL Classification Numbers:

The paper reports the results of a study of Australia's largest 250 companies' audit committees in two years (1998 and 2001). The audit committees were scrutinised on the bases of audit committee independence and the frequency of meetings. Australia's audit committees did not score highly on either criterion and most companies fell short of best practice guidelines. Further, it was puzzling and of concern that Australian audit committees appear to have deteriorated in terms of independence and frequency of meetings between 1998 and 2001. 相似文献

This paper examines the process of interaction between consumers and providers of dental services in terms of the key selection and evaluation criteria employed by consumers. Focusing on the United Kingdom, it examines the impact of changes in both pricing and provision on the utilisation and evaluation of dental services. Based on a questionnaire survey of dental patients, in the context of the evolving body of literature concerned with consumer behaviour in respect of services, the paper attempts to improve the current understanding of the key factors shaping consumer choice in respect of professional services. Specifically, it argues that the highly complex nature of professional services impacts on patterns of consumer behaviour, resulting in the relationship between the individual service professional and the consumer being the focus of consumer evaluation. This in turn has significant implications for the effective marketing of such professional services. 相似文献

Stochastic dominance efficiency criteria are used to rank the net farm return distributions for four different tillage systems under six different farm scenarios. Pairwise comparisons of tillage systems are carried over incremental upper and lower risk-aversion coefficient (RAC) bounds identified for each farm scenario, based on the size and spread of the outcome distributions to identify regions where dominance may switch between tillage systems. Ridge-till systems are generally the dominant tillage system for all farm scenarios considered. No-till systems on clay loam soils are more dominant in the risk-preferring range and less dominant in the risk-averse range, which relates to the relatively larger range of net return values and smaller mean net return values generated by this tillage system. Conversely, the moldboard plow and chisel plow systems are more dominant in risk-aversion intervals and less dominant in the risk-preferring intervals for clay loam soils. In sandy soil scenarios, the ridge-till and no-till systems are dominant over the two fall tillage systems for all farm sizes, indicating that these tillage systems are more competitive with conventional tillage systems in lighter soil type situations. A sensitivity analysis between moldboard plow and no-till systems indicates that no-till would dominate in risk-preferring intervals, and an increase in no-till net farm returns of 16 per acre would change dominance in favor of no-till in risk-averse interval space. On a utilisé les critères d'efficacitéà dominance stochastique pour classer les divers niveaux de recettes agricoles nettes dans quatre systèmes différents de travail du sol, selon six scénarios d'exploitation. Des comparaisons en paires des systèmes de travail ont été faites en regard de tranches croissantes des limites supérieures et inférieures du coefficient d'aversion du risque (CER), établies pour chaque scénario d'après l'importance et l'étendue des distributions du rendement, dans le but d'identifier les régions où la dominance serait susceptible de passer d'un système de travail à l'autre. Le système de travail sur billons était en général le système dominant dans tous les scénarios d'exploitation examinés. La culture sans travail du sol sur loam argileux était plus dominante dans les intervalles d'acceptation du resque et moins dominante dans les intervalles d'aversion du resque, cequi s'explique au fait que ce système de travail donne lieu à une fourchette relativement plus large, mais aussi à une moyenne plus faible du revenu net. À l'inverse, le labour à la charrue classique et au chisel dominait davantage dans les intervalles d'aversion du risque. Dans les sols sableux, le travail sur billons et la culture sans labour l'emportaient sur les deux autres régimes dans toutes les tailles d'exploitation, ce qui porte à croire que, dans les sols plus légers, ces régimes sont plus concurrentiels avec les systèmes classiques. L'analyse de sensibilité entre le labour à la charrue et les systèmes sans travail du sol montre que ces derniers dominent dans les intervalles d'acceptation du risque et qu'un accroissement du revenu agricole net de 16 /acre ferait glisser la dominance vers les intervalles d'aversion du risque. 相似文献

This paper models a commercial real estate project where a wealth-constrained manager uses outside debt financing to purchase a project who's return depends on future economic conditions and the manager's investment in the project. It is shown that it is inefficient to finance the project with callable debt. This prediction is consistent with observed real estate financing practice. I also model the outcome of financial distress allowing for (1) debt forgiveness, (2) equity in exchange for debt forgiveness, and (3) foreclosure. The model motivates (1) why commercial real estate loans are often foreclosed, and (2) why lenders foreclose assets at fire-sale prices. 相似文献

This article examines the earnings performance of nontraditional assets allowed to thrifts since the early 1980s. It uses the statistical cost accounting methodology developed by Hester and Zoellner to estimate average returns on thrift portfolio investments for the years ending June 30, 1987 and June 30, 1988. Results show that average returns on land loans, service corporation investment, real estate investment, and commercial loans were significantly lower than returns on more traditional assets. The results are far more pronounced at capital deficient institutions, lending support to the hypothesis that they used nontraditional investments as a means of exploiting the deposit insurance system. Returns on nontraditional assets are significantly affected by geographic factors, even for well capitalized institutions. The article concludes with an evaluation of the reimposition of portfolio restrictions on thrifts by the Financial Institutions Reform, Recovery, and Enforcement Act of 1989.The views expressed in this paper are those of the authors and do not necessarily represent the views or opinions of the Federal Housing Finance Board, the Board of Governors of the Federal Reserve System, or the Federal Deposit Insurance Corporation.

Customer discrimination may result in racial differences in the marginal revenue products generated by workers. College basketball
data allow for direct comparisons of the racial differences in the marginal revenues generated by players. This article compares
the revenue generating potential of the top black and white college basketball players. A highly skilled white college player
generates over $100,000 in per game revenues as compared to around $30,000 for a black player of equal talent, providing a
strong incentive for colleges to discriminate against recruiting black student-athletes. 相似文献
