Judgmental aggregation strategies depend on whether the self is involved

We report the results of a novel experiment that addresses two unresolved questions in the judgmental forecasting literature. First, how does combining the estimates of others differ from revising one’s own estimate based on the judgment of another? The experiment found that participants often ignored advice when revising an estimate but averaged estimates when combining. This was true despite receiving identical feedback about the accuracy of past judgments. Second, why do people consistently tend to overweight their own opinions at the expense of profitable advice? We compared two prominent explanations for this, differential access to reasons and egocentric beliefs, and found that neither adequately accounts for the overweighting of the self. Finally, echoing past research, we find that averaging opinions is often advantageous, but that choosing a single judge can perform well in certain predictable situations.     

Efficiency in the National Basketball Association: a stochastic frontier approach with panel data

We investigate how closely NBA teams play up to their potential. We find that shooting, rebounding, stealing the ball and blocking shots raise the number of potential wins while turnovers lower it. We also learn that better coaching and defensive prowess raise a team's win efficiency. Copyright © 2006 John Wiley & Sons, Ltd.     

Human resource management: when research confronts theory

Research exploring the relationship between human resource management (HRM) and outcomes such as corporate performance encounters a range of significant practical difficulties. Using two surveys as illustrative cases, this paper examines the practical challenges of operationalizing and measuring HRM, measuring the various outcomes and assessing the relationship between HRM and corporate performance. Despite the problems, it is suggested that significant progress has been made. While possible solutions to some of the problems are put forward, it is argued that a key requirement remains more clearly specified theory, particularly theory about the nature of HRM.

The Relationship Among Union Membership, Facets of Satisfaction and Intent to Leave: Further Evidence on the Voice Face of Unions

This study examined the impact of union membership on employees’ intent to leave their jobs across a number of facets of satisfaction, as a further test of unions’ voice face. Among the findings were that there were significant relationships between job, compensation, benefits, working conditions, and immediate supervisor satisfaction and intent to leave one’s job for nonunion employees. In contrast, only the relationship between job satisfaction and intent to leave was significant for union employees. Finally, over the facets of satisfaction where one would expect unions to have the most influence, the relationship between intent to leave one’s job and satisfaction was greater for nonunion employees than for union employees. These results provide a great deal of support for the effect of unions’ voice face.
