A serial supply chain of newsvendor problem with safety stocks under complete and partial information sharing

We consider a supply chain where multiple members are serially connected. The decision is to determine the ordering quantity of a member to the next upstream member in the supply chain. The basic cost model is similar to the newsvendor problem with additional consideration to safety stock. This paper presents optimal approaches for coordination of the supply chain under both complete and partial information sharing in order to maximize the total expected benefit. For complete information sharing we develop an optimal coordination algorithm. For partial information sharing, we propose an optimal coordination algorithm based on the Alternating Direction Method and the Diagonal Quadratic Approximation Method. A numerical example is discussed to show the optimal convergence of ordering quantities and discuss the properties of the proposed algorithms.     

Comparing Interpersonal Comparisons in Utility Theory and Happiness Research

Social scientists are reluctant to make explicit interpersonal comparisons of well-being. However, implicit comparisons are made on a surprisingly regular basis. These comparisons are based on the wealth and the Kaldor–Hicks concept in utility theory and on self-reported well-being in happiness research. Taking a utilitarian stance, this paper tests the ethical foundations of both principles. While self-reported well-being serves as an acceptable proxy for utilitarian decision-making, the Kaldor–Hicks concept does not appear so. Implications for evaluating policies are outlined.

Correlates of Drug Testing Attitudes in a Sample of Blue Collar Workers

Using responses from 1429 workers employed in the wood products industry, we examine the relationship between drug testing (DT) attitudes and several demographic, organizational, job attitude, and job outcome variables. After controlling for age and marital status, analyses revealed moderate correlations between DT attitudes and alcohol and drug variables, DT program characteristics, organizational, and work attitude variables. DT attitudes were weakly but significantly related to absences, late work arrivals, accidents, and injuries. Implications of the findings and future research suggestions are discussed.     

Rejoinder to Peltzman

Since 2008, the U.S. economy has been mired in the second worst economic crisis in its history. Conceivably, massive government spending could bring the economy out of this slump as massive war spending ultimately ended the Great Depression of the 1930s. However, a far superior strategy exists: guaranteeing employment accompanied by retraining to enable all unemployed workers to become absorbed into the regular work force. Beyond ending the crisis, the superiority of this strategy is that it would institutionalize a procedure for insuring that, in an increasingly technologically dynamic and open economy, workers would possess the necessary skills for available jobs. Guaranteeing employment would also eliminate the ecological costs associated with the need to seek growth to generate employment at practically any cost. Finally, it would establish a new moral social contract, whereby everyone is granted the dignity that accompanies being a productive member of society. Welfare for those able to work could disappear, along with the degradation and humiliation accompanying it.     

Attitude Sophistication and Effective Teaching in Economics

Little attention has been given to the measurement of changes in attitudes and beliefs resulting from instruction in economics. This deficiency is met by Mann and Fusfeld who relate attitude changes to growth in students' knowledge (cognition) and to characteristics of both students and instructors. The findings from this research suggest a conflict among the goals of instruction. They also imply greater persistence of changes in attitude than of changes in knowledge.
