基于模糊层次分析的供应链绩效评价

供应链管理的绩效评价,对于供应链运作和管理是至关重要的.本文在对供应链上单个企业的绩效评价指标的局限性的分析基础上,阐述了供应链指标体系作用及设计原则,并构建了供应链绩效评价指标体系,同时利用层次分析法确定各指标的权重,最后运用模糊综合评价方法从定量的角度对企业绩效评价方法进行研究,并给出评价过程.     

Institutional quality and the effectiveness of aid for trade

Trade policy barriers and high transaction costs hinder developing countries from taking the full advantages of the global trading system. In order to help developing countries overcome the problem, the World Trade Organization (WTO) launched the Aid for Trade (AFT) initiatives in its Ministerial Conference held in Hong Kong in 2005. We examine the effects of AFT inflows on bilateral trade costs facing 133 developing countries while accounting for differences in their location on the contours of various measures of institutional quality. Our results from the estimation of a mixed effects (random-intercept and random-coefficient) model indicate that institutional quality significantly affects the extent to which AFT reduces bilateral trade costs. An important policy implication of our findings is that an economically robust and sustainable reduction in bilateral trade costs facing developing countries requires the presence of both promulgated and effectively functioning institutions such as regulatory power and the rule of law.     

Ecological Transfers in Non-Human Communities Parallel Economic Markets in a General Equilibrium Ecosystem Model

Synopsis: The oft-cited analogies between ecological and economic systems are exploited to develop a many-species model of population dynamics. In economies, markets are the fundamental institutions in which the interaction of demands and supplies determine the quantities and prices of goods. However, economic markets are not appropriate for ecological communities, because markets rely on voluntary exchange, whereas plants and animals engage in involuntary transfers of biomass. A properly defined counterpart to markets based on biomass transfers permits a general equilibrium model of predator/prey and competitive interactions in a many-species community. Functional response from optimal foraging and predation risk provide the demand and supply, respectively, in the biomass transfers. Energy per unit time is scarce and predators and prey make optimum choices with respect to functional response and risk avoidance based on required energy expenditures. The energy expenditures are similar to economic prices: they determine foraging strategies and are beyond the control of the predators and prey, yet they are determined by the aggregate choices of all predators and prey and by population densities. The energies acquired from foraging are used in a new way to construct difference equations that determine the population dynamics.

政府国库资金、货币供给与货币政策有效性

政府财政行为对货币政策效应的影响是宏观经济学的一个热点问题,文章从政府资产角度出发,运用1994～2005年中国国库资金季度数据,采用协整分析方法对政府国库资金、货币供给和货币政策有效性问题,作实证检验。研究表明:(1)国库资金增减导致基础货币收缩和扩张,短期内国库资金变动会使货币供应量发生显著的反向波动,国库资金是货币供应量的Granger因,国库资金对货币供应量波动有较高的解释力,央行的货币供给由于国库资金而产生被动性。(2)国库资金与货币政策有效性之间存在密切关系,货币当局将国库资金变量纳入货币政策中介目标监控体系,有助于提高货币政策的有效性,国库资金成为财政政策与货币政策新的结合点。
