The Emergence of Individual Knowledge in a Group Setting: Mitigating Cognitive Fallacies 总被引:1,自引:1,他引:0
Daniel E. O’Leary 《Group Decision and Negotiation》2011,20(1):3-18
Research in psychology has found that subjects regularly exhibit a conjunction fallacy in probability judgments. Additional
research has led to the finding of other fallacies in probability judgment, including disjunction and conditional fallacies.
Such analyses of judgments are critical because of the substantial amount of probability judgment done in accounting, business
and organizational settings. However, most previous research has been conducted in the environment of a single decision maker.
Since business and other organizational environments also employ groups, it is important to determine the impact of groups
on such cognitive fallacies. This paper finds that groups substantially mitigate the impact of probability judgment fallacies
among the sample of subjects investigated. The key finding of this paper is the analysis of the apparent manner in which groups
make such decisions. A statistical analysis, based on a binomial distribution, suggests that groups investigated here did
not use consensus. Instead, if any one member of the group has correct knowledge about the probability relationships, then
the group uses that knowledge and does not exhibit fallacy in probability judgment. Having a computational model of the group
decision making process provides a basis for developing computational models that can be used to simulate “mirror worlds”
of reality or model decision making in real world settings. 相似文献

In order to understand the economic incentives behind gender discrimination in India, this paper provides the first estimates of the magnitude of the economic benefits of having a son instead of a daughter. The study estimates large gains from a first-born son to per capita income and expenditure, household assets, and a reduction in the probability the household is below the poverty line. Estimates show that a first-born son may provide economic advantages through a reduction in total children born and also from an adult son’s labor supply contribution to his parents’ household. The observed pattern of incentives is also compared with observed patterns in sex selection as a test of whether the relative economic value of first-born sons and daughters can explain the prevalence of sex-selective abortion. 相似文献

This paper examines the correlated random coefficient model. It extends the analysis of Swamy (1971), who pioneered the uncorrelated random coefficient model in economics. We develop the properties of the correlated random coefficient model and derive a new representation of the variance of the instrumental variable estimator for that model. We develop tests of the validity of the correlated random coefficient model against the null hypothesis of the uncorrelated random coefficient model. 相似文献

In this study, we compare a number of different approaches for determining the Value at Risk (VaR) and Expected Shortfall (ES) of hedge fund investment strategies. We compute VaR and ES through both model‐free and mean/variance and distribution model‐based methods. Certain specifications of the models that we considered can technically address the typical characteristics of hedge fund returns such as autocorrelation, asymmetry, fat tails, and time‐varying variances. We find that conditional mean/variance models coupled with appropriate assumptions on the empirical distribution can improve the prediction accuracy of VaR. In particular, we observed the highest prediction accuracy for the predictions of 1% VaR. We also find that the goodness of ES prediction models is primarily influenced by the distribution model rather than the mean/variance specification. © 2009 Wiley Periodicals, Inc.

The United States and China are at a turning point in their investment relationship. China’s previous investments in the United States were predominantly in government securities, while other holdings were negligible. Recently, the accumulation of treasury securities has slowed and direct investments by Chinese firms have risen steeply, with Beijing signaling greater support for portfolio investment outflows as well. This article describes the nascent shift in patterns of Chinese investment in the United States and uses the case of direct investment to examine the implications for US–China relations. We discuss current and future policy issues presented by Chinese foreign direct investment (FDI) in the United States, including national security, market access, and antitrust. 相似文献

This article enquires into the causes of union growth and decline by analysing flows in and out of membership at the level of 70 Swiss union locals over 2006–2008. Gross flows in union membership are much larger than the resulting net changes: annual membership turnover of 10 per cent is a surprisingly constant feature across unions. Net changes in membership are primarily determined by inflows: successful and languishing union locals differ in their entry rates, whereas exit rates are similar. Variance in union locals' entry rates is not usefully explained by the labour market context, but by differences in union strategy. 相似文献
