集团公司组织架构模式比较与分析

集团公司组织架构有三种模式 :过分集权的U型组织结构 ;过分分权的H型组织结构 ;集权与分权有机结合的M型组织结构。这三种模式的选择 ,将直接关系到企业的生存和发展。未来大庆石油集团公司的组织架构 ,应在选样M型的组织结构基础上 ,再进一步改造成新型组织架构。这种架构能否实现有效率的运转 ,关键在于集团公司对子公司、参股公司的管理与控制     

Paying to improve your chances: Gambling or insurance?

Will a more risk-averse individual spend more or less to improve probabilities, say on marketing efforts that enhance the chance of a sale? For any two payoffs and starting probabilities, the answer is unfortunately indeterminate. However, interpreting gambling as increasing small chances of good outcomes and insurance as reducing small chances of bad outcomes, the more risk-averse individual will pay less (more) to gamble (insure). We find a critical switching probability that depends on the individuals and outcomes involved. If the good outcome is less (more) likely than this critical value, the expenditures represent gambling (insurance).     

制度变迁与俄罗斯金融工业集团的形成

俄罗斯金融工业集团的兴起有着深刻的制度性根源。前苏联时期的高度集权制度和由此产生的官僚阶级是其形成的历史前提和阶级基础,20世纪80年代末期进行的经济体制改革则为其准备了经济基础。俄罗斯经济转型以后,金融工业集团的出现本质上是基于对不完善市场制度的修补,而激进改革政策则直接推动了它的建立和发展。另外,为了克服对转型策略选择的政治约束,俄罗斯政府实施的一系列扶持措施构成了对金融工业集团的重要外部支持。     

Left-Side strong increases in risk and their comparative statics

This paper introduces a new concept of left-side strong increases in risk (L-SIR) that extends the definition of strong increases in risk (SIR). We also provide somewhat stronger restrictive set of risk-averse decision-makers with a non-negative third derivative utility (prudence) to obtain an appealing comparative statics result for L-SIR.The authors gratefully acknowledge the helpful comments and suggestions of an anonymous referee     

Two-person sequential bargaining behavior with exogenous breakdown

We examine bargaining behavior in a noncooperative game in which players alternate in making and responding to proposals over the division of a given surplus. Although the number of bargaining periods is unlimited and time is not discounted, the bargaining is subject to exogenous breakdown at each period with a fixed probability which is common knowledge. We manipulate three probabilities of break-down in a between-subjects design that allows comparison with previous studies of two-person bargaining with time discounting. Assuming that subjects maximize expected utility, and this utility is measured by monetary payoffs, our results reject both the subgame perfect equilibrium and equal split solutions. Data analyses reveal that a substantial percentage of subjects behave adaptively in that they systematically search for the highest acceptable demands.     

Stochastic dominance in multicriterion analysis under risk

Traditionally, in the literature on the modelling of decision aids one notes the propensity to treat expected utility models and outranking relation models as rivals. It may be possible, however, to benefit from the use of both approaches in a risky decision context. Stochastic dominance conditions can be used to establish, for each criterion, the preferences of a decision maker and to characterise them by a concave or convex utility function.Two levels of complexity in preference elicitation, designated as clear and unclear, are distinguished. Only in the case of unclear preferences is it potentially interesting to attempt to estimate the value function of the decision maker, thus obtaining his (her) preferences with a reduced number of questions. The number of questions that must be asked of the decision maker depends upon the level of the concordance threshold that he(she) requires in the construction of the outranking relations using the ELECTRE method.     

成本收益、风险规避与人力资本投资

人力资本的投资可根据当时的利息率计算贴现值的方法进行决策.若需要用于投资的资本小于用期望收益算出的贴现值,则进行人力资本投资则为明智的选择.加大对人力资本的投资力度、人力资本的合理有效的组合和采取激励政策和规则可以规避人力资本投资风险.人力资本投资的的载体为具有主观能动性的人.要想投资取得成功,除了借助经济学方法做出正确的投资选择外还要充分调动被投资者--"人"的主观能动性.
