BENCHMARKING MANUFACTURING PERFORMANCE IN THE SEMICONDUCTOR INDUSTRY

A methodology for benchmarking manufacturing practices in the worldwide semiconductor industry is presented. Several metrics for measuring semiconductor manufacturing performance are defined and discussed. Interviews conducted during site visits are used to identify the managerial, technical, and organizational practices underlying superior metric performance. Multivariate statistical analyses of the performance metric data indicate that these performance metrics measure independent aspects of performance and expose significant performance differences among fabs.     

A Qualitative Study of Social Work Assessment in Cases of Alleged Child Abuse

Correspondence to Dr Dorothy Scott, School of Social Work, University of Melbourne, Parkville, Victoria, Australia 3052. Summary While there has been considerable theorizing about how socialworkers think and act, there has been relatively little researchin this area. In the study reported in this paper, in-depthinterviews and observations of practice were used to explorethe process of assessment undertaken by Australian social workersin a hospital specialist service and in a statutory child protectionservice. Using a semi-longitudinal approach which ‘shadowed’10 families (17 allegedly abused children), highly detaileddata were collected from 42 observations of practice and 123interviews with 12 hospital social workers and 15 child protectionworkers on how their assessments evolved over the life of thesecases. While there were some individual differences betweenpractitioners within each organization, of greater significancewere the marked differences between the two groups in the variablesto which they attended. Both groups tended to adopt a proceduralizedmodel of practice which narrowed the range of factorsconsideredin assessment.     

CAPITAL GAINS AND THE RATE OF RETURN ON A STRADIVARIUS

What is the return on a Stradivarius? The return equals the capital gain. The return on specific violin sales averages 2.17 percent. The best Stradivariuses were made in the “Golden Period.” Prices were significantly higher for Golden Period violins than for the other three periods examined. However, the rate of return was not significantly different for the four periods, with an overall return of 2.18 percent. When other factors (insurance, taxation and user benefits) were taken into account the rate of return varied between 4.7 and 1.2 percent.     

The Ipsative Process to Reduce Response Set Bias

Researchers who gather data from several different groups arefrequently faced with the problem of response set bias. Thispaper discusses the ipsative process, a technique which canreduce systematic response bias which exists between groupsin a study. The usefulness of the ipsative process is illustratedon cross-cultural research findings gathered in four countries     

CHEATING IN CONTESTS

Wherever competition is used to motivate a desirable activity or productive effort it may also motivate undesirable and therefore prohibited behavior—that is, cheating—that the organizer of the contest attempts to police. For example, when workers compete for promotion, bonuses, or other rewards, they may misrepresent their output (i.e., commit fraud) or increase their output by unacceptable means (e.g., violate regulations). We show how the extent of cheating is determined by the payoffs at stake in the contest, the random component of output, probability of cheating being detected, number of contestants, and the penalty associated with being found to have cheated. We find that while greater enforcement reduces cheating, it may also reduce productive effort. We also identify how two particular aspects of enforcement, the awarding of default victories and use of correlated rather than independent audits, affect cheating behavior. (JEL J33, K42)     

ECONOMIES OF SCALE IN BANKING,INDETERMINACY, AND MONETARY POLICY

This paper investigates economies of scale (ES) in financial intermediation as a source of equilibrium indeterminacy. Financial intermediation is embedded into a standard flexible‐price monetary model, and provides deposits (inside money) that substitute with currency to purchase consumption. The results indicate that equilibrium indeterminacy does not depend on a large degree of ES in intermediation nor a large intermediation sector, but on monetary policy and the determination of nominal interest rates. Monetary policies not targeting nominal rates allow for indeterminacy to arise for any positive degree of ES, while policies targeting nominal rates eliminate indeterminacy for all degrees of ES.
