农业自然资源与食物生产的类型迭置分析—以福建省为例

福建省粮食缺口逐年拉大,其它副食品也出现程度不同的短缺信号。在食物短缺的背后隐含着农业自然资源数量的短缺,并且随着人口的增长而日益严重。本文从农业自然资源与食物生产的内在联系入手,尝试对其丰乏程度进行定量的地域划分和迭置分析,进而探索各地域类型的食物发展方向与总体对策。

SOUTH KOREA'S PERFORMANCE EVALUATION SYSTEM: Some issues further considered

ABSTRACT * : The South Korean 1983 reform of government invested enterprises has been commonly regarded a success. In particular, the core element of the reform - the Performance Evaluation System (PES) - has been recommended as a model. This paper contributes to the existing understanding of the PES by arguing that it is strained by three inherent defects: measurement leniency vis-à-vis'diminishing rate of improvement: indicator complexity and excessive weight assignment to the qualitative criteria; and incentive divergence. These defects are interrelated and can work to joint affect - introducing perverse incentives, and therefore eroding the credibility of the system and, further, the reform. The causes of these defects should be identified either with inherent contradictions in the system itself or with inadequate institutional support, or both. Thus, there emerges from the discussion unlearned lessons from the Korean experience. Such unlearned lessons, however, should be considered in a much wider, public policy-making context .     

The conservative equal costs rule, the serial cost sharing rule and the pivotal mechanism: asymptotic welfare loss comparisons for the case of an excludable public project

We examine the asymptotic behavior of two strategyproof mechanisms discussed by Moulin for public goods – the conservative equal costs rule (CER) and the serial cost sharing rule (SCSR) – and compare their performance to that of the pivotal mechanism (PM) from the Clarke–Groves family. Allowing the individuals’ valuations for an excludable public project to be random variables, we show under very general assumptions that expected welfare loss generated by the CER, as the size of the population increases, becomes arbitrarily large. However, all moments of the SCSR’s random welfare loss asymptotically converge to zero. The PM does better than the SCSR, with its welfare loss converging even more rapidly to zero.
