研究了序列成本定价机制对同质分配模型公理体系的满足情况,并着重探讨了该机制与上限性、下限性、免费午餐、需求可控性和一致性公理的关系.在同质模型的前提下,序列成本定价满足除去成本函数单调性、一致性和需求可控性之外的所有公... 研究了序列成本定价机制对同质分配模型公理体系的满足情况,并着重探讨了该机制与上限性、下限性、免费午餐、需求可控性和一致性公理的关系.在同质模型的前提下,序列成本定价满足除去成本函数单调性、一致性和需求可控性之外的所有公理特性要求.比较了序列成本定价机制和平均成本定价机制满足上限性、下限性、免费午餐、需求可控性等公理的情况.结果表明,当代理人的需求不易控制时,平均成本定价具有明显优势;反之序列成本定价较好. 展开更多

The privatization of a firm entails a thoroughgoing process of reform that includes the introduction of new management practices. A review of the theoretical and empirical studies conducted allows us to confirm that a systematic analysis of the contextual, organizational and strategic factors that arise after a public company's privatization does not exist. This study explores the changes in strategic management that take place after a public company's privatization and proposes a theoretical global analysis model that facilitates their analysis. In order to confirm the theoretical propositions posed, the contemporary multiple case study was used as a research methodology. In particular, the changes experienced in the strategic management area in four privatized Spanish companies were investigated along the lines of a longitudinal analysis. The results of this study show that most theoretical propositions are confirmed or tend to be, according to the evidence shown by the firms in the sample. In addition, a comparative analysis of the different firms' behaviors by following the structure constructed on the basis of the three areas (strategies, objectives and organizational structure) leads to the conclusion that all these areas are relevant to the process of change in a privatized firm's strategic management. 展开更多
