Analysis and design of focused demand chains

The paper describes the evolution of focused demand chains over an extended period of time as a major UK lighting manufacturer has sought to remain an international player in a fast changing business environment. Analysis and design procedures make use of the concepts of Wickham Skinner and Marshall Fisher to answer the strategic questions “what facilities are required and how should they be laid out to enable the necessary focused demand chains?” and to answer the tactical question “which focused demand chain is appropriate for this product?” The case study then details how the company has been transformed from operating within a traditional supply chain to driving change via the engineering of four focused demand chains. The paper concludes with a comparison of operations enablers, customer choice, and business performance metrics covering the transition period culminating in the current focused demand chain scenario. By matching products to the appropriate value stream there is a consequential reduction in product development time of 75%; manufacturing costs reduction of up to 27%; and up to 95% reduction in delivery lead times.     

Encouraging Tutorial Attendance at University Did Not Improve Performance

When tertiary education is subsidised the cost of poor student performance in university subjects falls not only on the individual student but also on society in general. Society therefore has an interest in promoting student performance. There is evidence in the literature that absenteeism from university classes is widespread and that absenteeism adversely affects student performance. In this paper I describe an incentive scheme that increased attendance of business and economics students in an introductory statistics subject at a typical Australian university. Like other authors I find a strong positive association between attendance and academic performance, both in the presence and absence of the scheme. However, there is no evidence that the incentive scheme caused student performance to improve. Although students attended more classes they did not perform better than students in the previous year's class who had the same observable characteristics and attendance levels but who were not exposed to the scheme.     

The Effect of Government Regulations on Personal Loan Markets: A Tobit Estimation of a Microeconomic Model

The purpose of this paper is to analyze both theoretically and empirically the effect of selected government regulations on a high-risk personal loan market. Unlike previous studies, which have generally relied on a loosely specified theory and then tested this theory with statewide aggregate data, our analysis is based on a more tightly specified model for individual loans which is then tested using statewide disaggregated data. The empirical results indicate that the regulatory effects are not only significant but consistent with our theoretical microeconomic model.     

Race and employment dislocation in California’s aerospace industry

This article finds that African American and Latino workers have borne a disproportionate share of employment costs associated with defense cuts in California’s aerospace industry. The data for this analysis come from administrative files, which contain demographic and employment-related information for everyone who collects unemployment-insurance benefits. The analysis shows that African Americans suffered higher displacement rates, longer unemployment spells, and poorer outcomes in new jobs than whites. Latinos were disadvantaged in several ways, but not consistently in all categories. Asian Americans, on the other hand, generally fared better than whites. These results show that economic dislocation, in the form of defense cuts, reinforces racial inequality in the labor market.
