In this article we study a very simple trial and error learning process in the context of a Cournot oligopoly. Without any knowledge of the payoff functions players increase, respectively decrease, their quantity as long as this leads to higher profits. We show that despite the absence of any coordination or punishing device this process converges to the joint‐profit‐maximizing outcome.  相似文献

This paper analyses the decision of the Financial Reporting Council (FRC) to replace Australian accounting standards with international accounting standards on 1 January, 2005. Two main topics are considered: the appropriateness of the FRC's directive, and the case against the proposed adoption date. We argue that the FRC has not conducted sufficient consultation with affected parties and that the hasty implementation will impose costs that could have been avoided with the exercise of more caution.  相似文献

ABSTRACT The paper examines effects of executives’ orientations on crisis management awareness and practices, drawing on the simplicity and paradox management theories. It is suggested that a focus on single‐sided management constitutes an antecedent of crisis proneness. Employing a set of key corporate domains and based on a holistic organizational approach, the study aims at assessing the extent to which companies are crisis prone or prepared. In a sample of 82 Istaeli business and not‐for‐profit organizations it was found that human resource management, strategy, structure, and unlearning factors significantly predicted crisis preparedness. These results suggest that unlearning, despite a mere allusion to this correlate in the simplicity and paradox management theories, correlates better with crisis preparedness. By contrast, traditional strategy‐related and structural effects were marginally related to crisis management policies. Implications and suggestions for further research are proposed.  相似文献

Summary A sequential testing procedure called 2-SPRT for the meanμ of the negative binomial distribution with known exponentk is presented. For any fixedμ 0(μ 1<μ 0<μ 2), the 2-SPRT provides an asymptotic solution to the modified Kiefer-Weiss problem. Determination ofμ 0 such that the test provides an approximate solution to the Kiefer-Weiss problem is described. The behavior of the 2-SPRT and the Sequential Probability Ratio Test is investigated using Monte Carlo methods. The error probabilities and the average sample numbers are compared. All the computations were carried out on the Alabama Supercomputer.  相似文献

Prior studies show that the beta coefficient of a security changes systematically as the length of measurement interval is varied. This phenomenon, which is called the intervalling effect bias in beta, has been attributed to the friction in the trading system that causes the delays in the price-adjustment process. This study shows that option listing is associated with a decline in the beta intervalling effect bias. The decline is most pronounced for small firms. We also find that our sample firms grow significantly after option listing. Since prior research indicates that market value is a major determinant of the magnitude of the intervalling effect, we re-examine our results using a subsample that controls for market value. The results indicate that the decline in the beta bias from the pre-listing to post-listing period is still prevalent after we control for the change in firm size. Overall, the evidence is consistent with the notion that option trading reduces the delays in the price-adjustment process, which in turn reduces the intervalling effect bias in beta.  相似文献

An econometric model is used to measure the impact of the Three-Party Programme on European demand for U.S. orange juice. The results show that the programme has helped expand the demand for orange juice in European countries and, from the viewpoint of the U.S. citrus industry, is an economically preferred way of generating additional exports compared with using price reductions to achieve additional sales.  相似文献

Theoretical studies have shown that under unorthodox assumptions on preferences and production technologies, collateral constraints can act as a powerful amplification and propagation mechanism of exogenous shocks. We investigate whether or not this result holds under more standard assumptions. We find that collateral constraints typically generate small output amplification. Large amplification is obtained as a “knife‐edge” type of result.  相似文献

The authors present a comprehensive synthesis and evaluation of the published scales measuring the components of the decision making process in ethical situations using the Hunt-Vitell (1993) theory of ethics as a framework to guide the research. Suggestions for future scale development are also provided.  相似文献
