Experimental evidence of gender effects in arbitration decisions

The study investigates arbitrator gender and arbitrator-grievant gender effects on the decisions of 146 arbitrators rendered on a hypothetical sexual harassment case. Gender was not found to have a statistically significant effect on the decisions examined. However, other characteristics of the arbitrator—level of experience and level of education—were found to influence the arbitral decision.     

Goodness of fit for seemingly unrelated regressions: Glahn's R2y.x and Hooper's r̄2

This paper presents a measure of goodness of fit for Zellner's seemingly unrelated regressions. The measure is a monotonic transform of the appropriate (asymptotic) F-statistic, is bounded on [0, 1] and is maximized by Zellner's estimation technique. Glahn's composite correlation coefficient is shown to be a special case of this measure. It is also compared to Hooper's squared trace correlation coefficient. All three measures as well as some additional asymptotic summary test statistics are calculated for the two-equation example of Zellner. The applicability of the latter test statistics seems not to be recognized in applied work.     

Probabilistic Bounds on the Virtual Multipliers in Data Envelopment Analysis: Polyhedral Cone Constraints

The paper is concerned with the incorporation of polyhedral cone constraints on the virtual multipliers in DEA. The incorporation of probabilistic bounds on the virtual multipliers based upon a stochastic benchmark vector is demonstrated. The suggested approach involves a stochastic (chance constrained) programming model with multipliers constrained to the cone spanned by confidence intervals for the components of the stochastic benchmark vector at varying probability levels. Consider a polyhedral assurance region based upon bounded pairwise ratios between multipliers. It is shown that in general it is never possible to identify a center-vector defined as a vector in the interior of the cone with identical angles to all extreme rays spanning the cone. Smooth cones are suggested if an asymmetric variation in the set of feasible relative prices is to be avoided.     

Don’t kill the messenger! Whistle-blowing in America — A review with recommendations

Whistle-blowing in America business and industry has increased as interest in ethical business behavior and the cost of unethical behavior have grown. Whistle-blowing plays the important role of helping to fill the gaps in the regulatory system that is designed to check the abuse of organizational power. However, the practice of whistle-blowing is controversial and whistle-blowers often pay a high price for their actions. Firms can engage in a number of actions to encourage whistle-blowing. Creating a climate that encourages employees to report organizational wrong doing and that protects the whistle-blower is critical. To create such a climate the organization must build trust and cooperation by educating employees in the benefits of ethical and legal behavior.     

Adjusting to not being "on top": making effective use of transitions

In today's health care environment, it is possible even for the successful health care manager to be fired or demoted. To ensure continued success, the manager must view a termination or demotion as a normal transition of life and find ways to "move on". Given today's volatile environment, anticipatory planning for job loss or job change, which includes attention to continued professional training, visioning changes in health care, and maintaining strong professional contacts, is an imperative.     

Substitution of Noncash Payment Instruments for Cash in Europe

The substitution of noncash (check, giro, credit and debit card) payments for cash transactions is of interest for monetary policy and for determining central banks' future seigniorage revenue. We develop a novel method for approximating the share of cash transactions using public information on currency stocks, noncash payments, and card payment technology for 10 European countries. We also provide a forecast of future cash use by country. The trend in cash substitution across countries is quite similar, but the countries themselves are at significantly different stages in this process. The spread of debit and credit card payments has been the key factor behind the substitution away from cash as the use of electronic cash is still in its infancy.     

Networks: Between markets and hierarchies

Interorganizational networks generally have been discussed in the context of nonprofit agencies. Providing an alternative between the open market and the internalization of activity the network potentially may be even more important in business. This is especially true in international operations and in industrial and services marketing. Involving technology transfer, information exchange, accounting and finance as well as marketing, network management calls for a holistic approach. To serve as an engine of growth the network also requires strategic planning both at the overall level and in member firms.     

Measurement of Compensation: Union and Nonunion

For many purposes, the economic impact of unions is better measured by the proportion of union wages in total payrolls rather than by the proportion of unionized employees in the overall workforce. We use recently available Current Population Survey data to generate estimates of the former. We also show that published data from the Survey on median union and nonunion wages produce substantially larger estimates of the union 1 nonunion wage differential than figures based on mean wages. Finally, we note that the Bureau of Labor Statistics' Employment Cost Index gives undue weight to the union sector because of its Laspeyres methodology.
