创业投资机构对其支持企业IPO抑价度的影响 总被引:2,自引:0,他引:2
本文介绍了国外关于创业投资机构如何影响企业IPO抑价度的主要理论,在此基础上以我国的中小企业板上市公司为研究对象,通过比较分析发现与非创投支持企业相比创投支持企业有着更高的抑价度,进一步地研究表明该现象可用Am it et.al.[1]提出的逆向选择理论来解释。 相似文献

旅游企业员工招聘程序公平性的实证研究 总被引:2,自引:0,他引:2
对广东省几所高校和中等专科学校旅游管理及相关专业应届毕业生进行了一次调研,对美国学者鲍尔等人设计的员工招聘程序公平性计量尺度进行了实证检验。数据分析结果表明:(1)这个计量尺度有较好的可靠性和有效性;(2)管理人员在员工招聘工作中坚持公平性原则,可增强旅游企业吸引优秀人才的能力。 相似文献

We compare the performance of a wide set of regression techniques and machine-learning algorithms for predicting recovery rates on non-performing loans, using a private database from a European debt collection agency. We find that rule-based algorithms such as Cubist, boosted trees, and random forests perform significantly better than other approaches. In addition to loan contract specificities, predictors that refer to the bank recovery process — prior to the portfolio’s sale to a debt collector — are also shown to enhance forecasting performance. These variables, derived from the time series of contacts to defaulted clients and client reimbursements to the bank, help all algorithms better identify debtors with different repayment ability and/or commitment, and in general those with different recovery potential. 相似文献

近年来,普惠型医疗保险成为多层次医疗保障体系发展的一大热点。文章首先介绍了中国普惠型医疗保险的发展现状及主要特点,其次通过对国内部分保险公司线上及线下调研,发现当前普惠型医疗保险发展面临配套法律法规有待健全、市场认可度普遍偏低、可持续经营能力不强、保险效果低水平重复、相关主体联动不足等困境。进一步分析美国、英国、德国、新加坡相关经验,提出具体的优化路径:以优化顶层设计为立足点,提高保险规制水平;以强化市场环境建设为切入点,提升市场认可度;以优化运行模式为突破点,激发保险生命力;以设计差异化产品为关键点,强化保险增补性;以建立联通机制为动力点,提高相关主体协同度。 相似文献

Economic literature on groundwater managementhas traditionally been split into two areas: there are papers that evaluate different
schemes of dynamicaquifer management, considering that pumping costs vary with stock but ignoring water quality. On the other
hand, there are papers that considercontamination problems caused by specificpollutants. This paper presents two alternative
models for joint quantity-quality management, and it shows that existing models are in fact special cases of these. The framework
isdynamic and considers both the stock of waterquantity and a stock measure of water quality. Optimal taxes are derived, and
shown to be different from those in existing quantity-only or quality-only models. Implementationproblems are briefly discussed. 相似文献

Summary. We study a one-sector stochastic optimal growth model with a representative agent. Utility is logarithmic and the production function is of the Cobb-Douglas form with capital exponent
. Production is affected by a multiplicative shock taking one of two values with positive probabilities p and 1-p. It is well known that for this economy, optimal paths converge to a unique steady state, which is an invariant distribution. We are concerned with properties of this distribution. By using the theory of Iterated Function Systems, we are able to characterize such a distribution in terms of singularity versus absolute continuity as parameters
and p change. We establish mutual singularity of the invariant distributions as p varies between 0 and 1 whenever
. More delicate is the case
. Singularity with respect to Lebesgue measure also appears for values
such that
. For
and
Peres and Solomyak (1998) have shown that the distribution is a.e. absolutely continuous. Characterization of the invariant distribution in the remaining cases is still an open question. The entire analysis is summarized through a bifurcation diagram, drawn in terms of pairs

Global warming is currently an important item on most nationalenvironmental agendas. In many countries, coal-fired electricity generatingstations represent an important source of greenhouse gases. We examinehow regulations to curb emissions affect public utility pricing regulationwhen regulators act non-cooperatively. We show that, when there is limitedinformation on fixed abatement costs, an environmental regulator prefersan emission tax over an output tax or a lump sum environmental tax. Thepublic utility regulator prefers the lump sum tax regime. 相似文献

Studying a principal-agent game in which the agent alone observes the state of the world and reports it, but the moral hazard is not reducible, shows that, if the principal uses all signals, then no solution exists, i.e. there is no contract that elicits truth-telling and motivates the agent to exert effort. When the principal does not use signals on the state of the world that seem irrelevant, a solution exists in which some of the ex post signals on outcome are not used, even though they obey the informativeness condition of Holmstrom (Bell Journal of Economics, 1979, 10, 74–91). 相似文献

财政透明化背景下的政府治理变革 总被引:6,自引:0,他引:6
财政透明度是民主社会中更为广泛的公众知情权和政府信息披露制度的重要组成部分。中国财政透明度同发达国家相比存在很大的差距,甚至落后于许多发展中国家。本文通过对财政透明度的基础理论分析,认为财政透明化作为政府治理变革的核心,对于政府治理效率的提高有积极性影响。为了适应经济全球化发展趋势,在更多领域内参与国际竞争与合作,就必须规范政府行为,实现政府治理再造, 相似文献
