创业投资机构对其支持企业IPO抑价度的影响

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。     

旅游企业员工招聘程序公平性的实证研究

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。     

跨国公司对华直接投资区位选择战略比较研究

区位因素是影响跨国公司制定对外直接投资战略的重要因素之一。本文以日本、韩国、美国、港澳等国家和地区为代表,分析了跨国公司对华直接投资的动机及区位选择战略,在此基础上提出加入WTO之后中国企业海外直接投资的区位选择战略。     

普惠型医疗保险发展:实践困境与优化方向

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。     

Regulating an Externality-Generating Utility Environmental Taxes Under Limited Information

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.     

Characterization of a class of moral-hazard, adverse selection games

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).     

财政透明化背景下的政府治理变革

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，     

The Effect of Protest Votes on the Estimates of WTP for Use Values of Recreational Sites

Contingent valuation studies are often characterized by a considerable number of protest responses, which may cause selectivity bias on the final estimates for WTP. Sample selection models can detect and – if necessary – correct selectivity bias. In economic applications where the relevant dependent variable is continuous, sample selection models are generally estimated using Heckman's 2-step method rather than the FIML estimator. Either method has its own drawback: computational complexity for the FIML method, susceptibility to collinearity problems for the 2-step method. Using data on valuation of forest resources for recreational use, we analyse the performance of the two estimators. In this application, given the presence of some collinearity, the FIML is preferred to the 2-step method. A procedure is outlined to deal with selectivity problems in similar settings.     

Comparison of Hypothesis Testing and Bayesian Model Selection

The main goal of both Bayesian model selection and classical hypotheses testing is to make inferences with respect to the state of affairs in a population of interest. The main differences between both approaches are the explicit use of prior information by Bayesians, and the explicit use of null distributions by the classicists. Formalization of prior information in prior distributions is often difficult. In this paper two practical approaches (encompassing priors and training data) to specify prior distributions will be presented. The computation of null distributions is relatively easy. However, as will be illustrated, a straightforward interpretation of the resulting p-values is not always easy. Bayesian model selection can be used to compute posterior probabilities for each of a number of competing models. This provides an alternative for the currently prevalent testing of hypotheses using p-values. Both approaches will be compared and illustrated using case studies. Each case study fits in the framework of the normal linear model, that is, analysis of variance and multiple regression.     

逆向选择条件下技术许可中非排他性价格契约研究

通过经典的委托代理理论的应用,文章揭示了一类逆向选择条件下的技术许可中非排他性价格契约理论的内在机理。文章认为,通过针对差的类型的技术使用者的包含可变费用的契约和对好的类型的技术使用者的纯固定费用的契约,可以达到有效的排他性技术许可的目的;但为了有效的激励,技术所有者事前要对好的类型的技术使用者转移一定的信息租。
