Additive and Multiplicative Uncertainty Revisited: What Explains the Contrasting Biases?

above the certainty level while for additive uncertainty the price should be lower than the certainty level. This note gives an intuitive explanation for the result after first presenting a parsimonious review of the two models. We also discuss which, if either, of the two models is more realistic.

Corporate Board Composition, Protocols, and Voting Behavior: Experimental Evidence

We examine voting by a board designed to mitigate conflicts of interest between privately informed insiders and owners. Our model demonstrates that, as argued by researchers and the business press, boards with a majority of trustworthy but uninformed “watchdogs” can implement institutionally preferred policies. Our laboratory experiments strongly support this conclusion. Our model also highlights the necessity of penalties on insiders when there is dissension among board members. However, penalties for dissent appeared to have little impact on the experimental outcomes.     

Should we let employees contract away their rights against arbitrary discharge?

This article argues that the moral right to be discharged only for good cause and like rights can be contracted away by employees in appropriate circumstances. It maintains that the rights in question are not inalienable, and that there is nothing irrational about an employee's wishing to deal them away. It also maintains that inequalities in bargaining power between employers and employees are insufficiently pervasive to justify a flat ban on the alienation of these rights. For a waiver of such rights to be valid, however, employees must have full knowledge of its terms.The question addressed here bears on several legal and policy issues affecting termination of the employment relation. If employees can contract away their right to a goodcause discharge, the American doctrine of employment at willmight find justification in the face of that right. In addition, the alienability of such discharge rights may be necessary to justify express disclaimers of wrongful discharge liability and the waiver provision of the new U.S. Draft Uniform Employment-Termination Act.Michael J.

The R&D Effectiveness Index: A Metric for Product Development Performance

Measuring the overall success of product development efforts has been frustrating because there is no generally recognized metric to measure effectiveness. The R&D Effectiveness Index is introduced to address this need. It measures effectiveness by comparing the profit from new products to the investment in new product development. The article provides the details for calculating the index along with alternative interpretations. Michael McGrath and Michael Romeri report that this index was validated through a study of 45 electronic systems companies. They found a strong relationship between the R&D Effectiveness Index and other performance factors and believe that the R&D Effectiveness Index can be used to compare performance, measure improvement, and evaluate business units. Its application is illustrated in a case study.
