Cost analysis of water utilities: A goodness-of-fit approach

The behavior of privately owned and publicly owned water utilities is examined by calculating the percentage difference between the observed cost and the optimum cost consistent with the Weak Axiom of Cost Minimization for each individual water utility. It allows for a comprehensive analysis of nearly optimizing behavior of economic units as opposed to the conventional analysis of exact optimizing behavior. The empirical results provide evidence that private water utilities are more efficient than public water utilities.     

Conflict resolution in organizational buying centers

This article reports the results of a field study of buying center conflict and conflict resolution processes—factors often seen as key ingredients in modeling the organizational buying process. The problem-solving and persuasion modes were found to be more often used than the potentially destructive power and politics modes. As expected, increasing levels of conflict were found to be associated with confrontation-oriented modes of resolution. Differences in resolution mode across stages of the purchase process were not significant.     

GENERIC PROMOTION OF BEEF: MEASURING THE IMPACT OF THE US BEEF CHECKOFF

Generic promotions of commodities are growing in importance. In the US, commodity industry assessments or checkoffs (i.e. a per unit levy or tax) are used to underwrite domestic and international promotions by commodity groups. The US beef checkoff is one of the largest of these new national commodity programmes. Evaluation of the economic impact of the beef promotion is an essential part of the beef checkoff. A model for evaluating the US beef programmes is estimated and the methodology is applicable to other commodity models that include advertising and promotion expenditures. The beef analysis shows a positive and significant return to the beef industry, with an average of approximately $5 for each $1 invested for the quarters 1987:1 through 1991:2.     

Simulated financial dealing room: learning discovery and student accountability

This paper identifies the effectiveness of a simulated treasury dealing room for teaching and learning. It uses a presurvey and a postsurvey to establish student perceptions of learning effectiveness. It concludes that students believe that the dealing room: (i) improves their opportunities to apply theory; (ii) provides better learning than lectures; (iii) is more effective than individual learning; (iv) improves student monitoring of learning effectiveness; and (v) improves student abilities to recognize ethical issues, develop alternative solutions to ethical problems, and evaluate solutions to ethical problems from a moral point of view. Student motivation is enhanced by: (i) the high value they place on dealing room learning; (ii) their preparedness to participate; (iii) rapidly reduced levels of anxiety about trading; and (iv) the learning resources provided.     

Horizontal Inequity and Vertical Redistribution

Inequality of post-tax income among pre-tax equals is evaluated andaggregated to form a global index of horizontal inequity in the income tax.The vertical action of the tax is captured by its inequality effect on averagebetween groups of pre-tax equals. Putting the two together, horizontalinequity measures loss of vertical performance. The identification problem,which has previously been thought insuperable, is addressed by a procedurevalidating the banding of income units into close equals groups. Thehorizontal and vertical effects of a major Spanish income tax reform areevaluated. Lines for future investigation are suggested.

Establishing Logistics Service Strategies That Increase Sales

While the linkage between logistics performance and firm performance has received attention in the literature, typically firm performance is measured as customer satisfaction and customer loyalty rather than share of business or other measures that translate into a financial benefit. Thus logistics executives continue to be judged primarily on cost and asset reductions. Only one study has documented how logistics performance affects customer satisfaction and the percentage of business allocated to the suppliers as well as the differences in outcomes between firms identified as primary and secondary suppliers (Leuschner et al. 2012 ). In this research, we use samples in the motion picture and video production industry, and the plastic materials and resins industry to investigate the impact of the Marketing Mix on customer satisfaction and share of business. Our results differ from Leuschner et al. ( 2012 ) regarding the impact of product, price, and promotion on customer satisfaction, but we confirm the impact of logistics performance on customer satisfaction and the relationship between customer satisfaction and share of business for primary and secondary suppliers combined. Finally, we provide a framework to identify logistics service strategies based on a customer's current profitability, potential growth, and the share of a customer's purchases obtained.
