With declining enrollments, metropolitan school districts are faced with problems of property disposition. A school facilities planning and management model utilizing a linear programming approach enables assessment of alternative uses for school facilities. The objective in this study is to minimize expenditures subject to constraints which include a limit to distance traveled, racial ethnic quotas, and overhead costs, such as transportation, maintenance and energy. An economic post-optimal cost sensitivity analysis of the proposed options is presented and also a comparison of this approach to school management with others found in the literature. 相似文献

Is Wheat a Homogeneous Product? 总被引:1,自引:0,他引:1
Bruno Larue 《Revue canadienne d'agroeconomie》1991,39(2):103-117
A hedonic approach is used to test for two kinds of product differentiation for wheat. It is shown that wheat is differentiated by end use and by country of origin. This simply recognizes the fact that buyers purchasing wheat for different purposes put different weights on quality criteria and that country-specific factors such as weather as well as grading and inspection systems matter. The results suggest that between 1980 and 1988, wheat protein content had a significant influence on price. This influence varies over time and across wheat categories. 相似文献

This paper extends He and Pearson's (1991) martingale approach to the study of optimal intertemporal consumption and portfolio policies with incomplete markets and short-sale constraints to a framework in which no assumptions are made on the price process for the securities. We show how both their characterization of the budget-feasible set and duality result can be extended to account for an unbounded set II of Arrow-Debreu state prices compatible with the arbitrage-free assumption. We also supply a (fairly general) sufficient condition for II to be bounded, as required in their setting. 相似文献

The patterns of development of 250 high-technology firms, are examined. As of 1980, 36.8% of these firms had discontinued, 30.8% were surviving and independent, and a remarkably high 32.4% had been acquired. The characteristics of both the acquired and acquiring firms are examined and reveal distinctive patterns of acquisition. 相似文献
