Subjects update prior information simultaneously versus sequentially. The mean prediction is remarkably close to the correct Bayesian estimate with simultaneous information, but differs significantly conditional on whether good news precedes bad news or vice versa. 相似文献

We consider the consequences of a scientific literature with only one model of an important phenomenon. The falsification
of the model would mean falsification of the science. Scientists who would prefer not to have their discipline falsified will
be tempted to find ad hoc explanations to excuse the failure. To test this hypothesis we propose a study of the economic forecasts
of the comparative Soviet and American growth rates in the years before a public choice model of central planning was a viable
alternative to the public interest model.

Earlier versions of the paper were presented at the University of Manitoba Economics Department Retreat in October 2005 and
at the Center for Study of Public Choice Wednesday Seminar in November 2005. We thank the participants for their suggestions.

The federal government and many state governments have recently passed legislation that punishes school districts for not showing consistent improvement in standardized test scores. This article measures the extent to which school performance reflects student characteristics. After splitting schools in the state of Washington based on adequate yearly progress, the authors find that an overwhelming percentage of the difference between high- and low-performing schools is explained by characteristics beyond the control of school administrators. Thus legislation designed to penalize poorly performing schools may hurt students who are most in need of academic aid. (JEL I2 ) 相似文献

The Myerson's models on partial cooperation have been studied extensively [SIAM J. Discrete Math. 5 (1992) 305; Math. Methods Operations Res. 2 (1977) 225; Int. J. Game Theory 19 (1980) 421; 20 (1992) 255]. In [Game Econ. Behav. 26 (1999) 565], Hamiache proposes a new solution concept for communication situations. In this work, we analyze this value making some deficiencies clear and generalize this value to union stable cooperation structures emphasizing the differences in the extension. 相似文献

Multiple objects may be sold by posting a schedule consisting of one price for each possible bundle and permitting the buyer to select the price-bundle pair of his choice. We identify conditions that must be satisfied by any price schedule that maximizes revenue within the class of all such schedules. We then provide conditions under which a price schedule maximizes expected revenue within the class of all incentive compatible and individually rational mechanisms in the n-object case. We use these results to characterize environments, mainly distributions of valuations, where bundling is the optimal mechanism in the two and three good cases. 相似文献

Nurse managers demonstrating transformational leadership are more likely than transactional leaders to have committed staff nurse followers. Committed followers exert extra effort, thus improving unit performance and enhancing the organization's competitive advantage. 相似文献

The distribution of shocks to GDP growth rates is found to be exponential rather than normal. Their standard deviation scales with GDPβ where β=−0.15±0.03. These macroeconomic results place restrictions on the microeconomic structure of interactions between agents. 相似文献

Quality assurance is an important responsibility of those who purchase managed vision care benefits. In conducting a quality assurance program, it is important to respect patient confidentiality and the practitioner's right to exercise professional discretion. An effective program will not only accomplish its main objective of attaining high-quality care, but it can also enhance member satisfaction and improve provider relations. 相似文献
