农户防范返贫:应该更关注人力资本还是社会资本?

基于部分中国家庭追踪调查微观数据,利用多维返贫测算方法识别返贫农户,实证检验了人力资本和社会资本在农户防范返贫中的效应和机制。研究发现:(1)人力资本和社会资本均是防范农户多维返贫的重要因素,但从返贫效应的视角看,人力资本防范返贫的影响更大,是巩固拓展农村脱贫攻坚成果的关键资本。(2)机制分析中,人力资本能发挥迁移效应,通过劳动力流动的部分中介作用防范农户返贫,而社会资本能发挥信息获取和抵押品效应,通过创业的部分中介作用防范农户返贫。(3)人力资本降低了农户在收入、医疗、生活维度的返贫发生概率,社会资本则降低了收入、医疗维度的返贫发生概率。(4)两类资本的防范返贫效应存在区域差异,人力资本显著降低东部和西部农户返贫发生概率,而社会资本显著降低了东部和中部农户返贫发生概率。

The design of organizations and the right to act

Recent innovations in the structure of formal organizations suggest possible directions for the design of schools to bring about high achievement. The structure of output-driven in contrast to administratively-driven schools is described, and designs are described which address both the goal of high achievement and the goal of reduced inequality.An earlier version of this paper was presented as the author's Sorokin Lecture at the annual meeting of the Eastern Sociological Society, Boston, March 1993.     

Managing Uncertainty through Profit Sharing Contracts from Medieval Italy to Silicon Valley

Organizational innovation is essential to economic development. But, the way successful societies have organized new ventures has been remarkably similar in both past and present. The commenda organizations of medieval Italy shared many characteristics with modern startups that are financed by venture capital. Profit share contracts; limited liability and periodic reevaluations are cases in point. Agency contracts in both types of ventures are designed to absorb the high uncertainty inherent to these enterprises through risk sharing. Uncertainty prohibits a unique ex ante ranking order of investment projects and prompts investors to look for hidden human capital. Equity finance is better equipped to even out unexpected losses and gains that are inherent to uncertainty than debt finance.     

Two phase parametric and probabilistic NPV calculations, with possible deferral of disposal of UK nuclear waste as an example

This paper illustrates the value of several particular features of a first phase parametric approach to discounted cash flow (DCF) decision analysis when significant uncertainty is involved. It also illustrates the value of second phase probabilistic approaches to selected parameters for five quite different example reasons. The most controversial example reason concerns the discount rate. The particular example used to illustrate both phases may stimulate general interest because of the important issues involved, but it is argued that the two phase approach as a whole has a wide range of applications for decisions large and small.

成熟期医药风险投资项目评价实证研究

作为关系国计民生的特殊产业--医药产业一直是风险投资重要领域,但是针对性相关研究却没有得到应有重视,而专注于医药风险投资重要阶段的成熟期医药风险投资的相关研究更是空白.现有风险投资文献多比较原则,少数套用有关方法、模型改头换面,缺乏实际应用价值.鉴于成熟期医药风险投资特点,本文通过问卷调查和数理统计方法从实证角度揭示成熟期医药风险投资各风险评价指标及重要性和相互关系.通过相关性分析发现成熟期医药风险投资协同效应评价中的负相关性现象.

企业组织中人力资本道德风险因素分析

基于市场里的企业是“一个人力资本与非人力资本的特别合约”的观点,就人力资本的道德风险问题进行了研究。认为影响人力资本道德风险的因素主要有诚实履行合约后的正常收益、道德风险行为被发现的概率、贴现因子、道德风险行为的额外收益以及道德风险行为被发现后的次优收益。并且以预期收益为目标建立了数学模型,分析人力资本道德风险行为动机与影响因素之间的关系,提出了相关的激励、约束及协作策略。最后,讨论了随机因素的影响。     

市场时机对资本结构影响的持续度研究

市场股价信息会不断影响股权融资决策,对资本结构的影响甚至出现累积效应。为此,从中长期的角度探寻历史市场时机对公司资本结构形成和杠杆累计变动的影响,并具体测算出市场时机对资本结构影响的持续程度。研究表明,市场价格高的公司不仅在短时间内愿意进行股权融资,而且过去的市场价格信息也会对资本结构产生中长期的影响,在一定时间里不断累积。这种信息的影响大约会持续5年左右。
