对因突发事件临时停牌的股票和长期停牌的股票进行估值,可以借鉴国外对冲基金经常采用的“侧袋存放”机制。在公募基金行业中采取按允许赎回不允许申购、同时允许申购和赎回两种模式,具体实施机制各不相同。实施“侧袋存放”机制在基金持有人利益、IT系统支持、信息披露、费用计提等方面存在的一些难点。 相似文献

We analyze how the agent's initial wealth affects the principal's expected profits in the standard principal–agent model with moral hazard.We show that if the principal prefers a poorer agent for all specifications of action sets, probability distributions, and disutility of effort, then the agent's utility of income must exhibit a coefficient of absolute prudence less than three times the coefficient of absolute risk aversion for all levels of income, thus strengthening the sufficiency result of Thiele and Wambach (1999). Also, we prove that there is no condition on the agent's utility of income alone that will make the principal prefer richer agents. Moreover, we show that, for an interesting class of problems, the principal prefers a relatively poorer agent if agent's wealth is sufficiently large. Finally, we discuss how alternative ways of modeling the agent's outside option affects the principal's preferences for agent's wealth. 相似文献

Parents and policy‐makers often wonder whether and how the choice of a tracked or mixed educational system affects the equality of opportunity. I answer this question by analyzing the influence of peers on future educational results. I define an equal opportunity policy as one that maximizes the average lifetime income of the worst‐off type of individuals in society (i.e., students from disadvantaged backgrounds). I find that tracking maximizes average lifetime income if the opportunity cost of college attendance is sufficiently high. 相似文献

We adopt the view that greater party discipline induces legislators to commit to promised policies after being elected. We then develop the hypothesis that the effect of party discipline on the stringency of environmental policy is conditional on the degree of government corruption. Our empirical work suggests that greater party discipline results in more stringent environmental policies when the level of corruption is relatively low, but in weaker policies when the level of corruption is comparatively high. 相似文献

Abstract Income growth in highly industrialised countries has resulted in consumer choice of foodstuffs no longer being primarily influenced by basic factors such as price and organoleptic features. From this perspective, the present study sets out to evaluate how and to what extent consumer choice is influenced by the possible negative effects on health and environment caused by the consumption of fruit containing deposits of pesticides and chemical products. The study describes the results of a survey which explores and estimates consumer willingness to pay in two forms: a yearly contribution for the abolition of the use of pesticides on fruit, and a premium price for organically grown apples guaranteed by a certified label. The same questionnaire was administered to two samples. The first was a conventional face-to-face survey of customers of large retail outlets located around Bologna (Italy); the second was an Internet sample. The discrete choice data were analysed by means of probit and tobit models to estimate the utility consumers attribute to organically grown fruit and to a pesticide ban. The research also addresses questions of validity and representativeness as a fundamental problem in web-based surveys. 相似文献

We adapt the dissonance‐minimising (DM) format proposed by Blamey et al. [Land Economics, 75 (1999) 126] in a dichotomous choice contingent valuation survey to estimate the economic benefits of preserving a cultural heritage site in Vietnam. We find that the DM format can be successfully applied to avoid biases because of yea‐saying in a developing country context. 相似文献

高铁网络的建设大大提高了中国铁路运输的效率,缩短了不同城市之间的时空距离,使居民在不同城市工作和消费成为可能。同时高铁服务通过加速人口和要素在区域间的流动,对城市之间的空间联系和城市社会经济的发展产生了重要的影响。高铁在影响经济格局的同时也深刻影响了区域的创新格局,现通过梳理相关文献,整理归纳了高铁开通对城市创新的影响及其作用机制,并对现有的实证研究方法进行总结。在此基础上提出目前存在的问题,为后续的研究指明方向。 相似文献

融资理论的实践效应及其验证——基于中国上市公司的数据分析 总被引:2,自引:0,他引:2
融资理论是企业制订融资政策的理论基础.不同的融资理论及管理思想将会导致企业采用不同的资金管理策略与政策.因此,融资理论及其实践效应又是预测企业资金管理政策的重要参数.本文以中国上市公司为基础,重点探讨优序融资理论和权衡融资理论在中国企业管理实践中的应用情况.研究表明,这两种理论在中国企业管理实践中都得到了不同程度的应用,但是比较而言,优序融资理论的受支持程度要高于权衡理论的受支持程度. 相似文献

本文探讨了新型农村社会养老保险是否对低收入的贫困群体的生活产生更显著的效用,从而论证该制度是否助力扶贫工作。因为养老金是收入的组成部分,而收入有边际效用递减的特点,因此养老金对不同收入群体的效用可能存在差别。本文按家庭人均收入水平区分贫困与非贫困群体,基于CHARLS 2011 -2015年数据,采用多维贫困指标,使用断点回归发现新农保养老金对贫困参保群体在食品消费方面产生更显著的效用,有助于扶贫工作。并使用含复杂时变效应的二元变量模型,进一步发现该效用在养老金开始发放时显现。本文结论有利于认识新农保政策对扶贫的作用,并将扶贫工作和已有的社会保险政策结合,以提高扶贫工作效率。 相似文献

ABSTRACTThis paper empirically investigates whether the productivity of a public (government-funded) R&D project improves when the aggregate R&D investment in the same technology field increases. Based on the unique project level data that cover almost entire public R&D projects in Korea, this paper shows that aggregate investment in other public R&D projects in the same technology field increases a public R&D project’s outputs both independent of its project expenditure (additive spillover effects) and interactive with its project expenditure (multiplicative spillover effects). The spillover effects from the aggregate private R&D investment in the same technology field also exist, but to a much lesser extent. 相似文献
