新时期高校先进性教育长效机制建设浅议

高等学校是培养建设有中国特色社会主义事业接班人的重要阵地。如何教育、培养学生党员践行“三个代表”重要思想,充分发挥先锋模范作用,增强党的战斗力、凝聚力和吸引力,是高校学生党建工作的重要组成部分和基础环节。探索加强学生党员的思想政治教育、组织机制、制度建设、激励机制的建设,是新时期高校党建工作的一项重要课题。     

武汉市居民社区参与现状及制约因素——对武汉市的调查与分析

居民参与是中国城市社区建设和发展的动力,目前城市社区参与呈现出良好发展态势,但社区参与还存在很多问题,如组织化参与少、外来式参与少、非政治性参与多、参与效能低、参与主体单一等.主要原因是社区公民意识薄弱、利益表达机制欠缺、社区组织化程度不高、社区行政化严重等.     

基于产品生命周期的高新技术企业融资模式研究

针对高新技术企业在不同生命周期阶段的风险特征及传统融资模式的不足，应采取以高新技术项目为核心、以政府基金为基础、以风险投资为动力、以资本市场为源泉的四元融资模式。该模式不仅适应高新技术企业多产品生产的融资需要，而且可实现多种融资渠道之间的互动。

Matching using semiparametric propensity scores

This paper considers the application of semiparametric methods to estimate propensity scores or probabilities of program participation, which are central to certain program evaluation methods. To evaluate the practical benefits, we first conduct a Monte Carlo study. Second, we use data from the NSW experiment, CPS, and PSID. We compare treatment effect and evaluation bias estimates using propensity scores estimated from parametric logit, semiparametric single index, and semiparametric binary quantile regression models. Our results suggest that it is important to account for very general forms of heterogeneity in (semiparametric) estimation of the propensity score, particularly when the treatment effects vary in an unsystematic manner with the true propensity score.     

高阶梯队理论视角下控制权对不同背景领导者与研发投入间关系的调节机制

从高阶理论和委托-代理理论出发,利用2007—2015年中国沪深两市上市公司公开披露的数据,考察了实际控制人的控制权、具有不同专业背景的领导者与研发投入的关系,厘清了控制权对具有不同专业背景的领导者对研发投入影响的作用机制。实证结果表明,控制权是具有不同专业背景的领导者与研发投入之间的调节变量。具体而言:具有技术背景的领导者对研发投入的影响随着实际控制人控制权的增大而减小;具有社科背景的领导者对研发投入的影响随着实际控制人控制权的增大而增大。     

The robustness of the independent private value model in Bayesian mechanism design

Summary. In a Bayesian model of group decision-making, dependence among the agents' types has been shown to have a beneficial effect on the design of incentive compatible mechanisms that achieve the efficient choice associated with complete information. This effect is shown here to depend as much upon the use of large monetary transfers among the agents as it does upon dependence: if the transfers are bounded in magnitude, then nonexistence in the case of independence of an efficient, incentive compatible, ex ante budget-balanced and interim individually rational mechanism is robust to the introduction of a small amount of dependence among types. This robustness result supports the use of the simplifying assumption of independence in mechanism design. Received: October 28, 1996; revised version: May 28, 1997

Microeconometric models of infrequently purchased goods: An application to household pork consumption

The double-hurdle and infrequency-of-purchase models are generalized with the inverse hyperbolic sine transformation in the dependent variable. The resulting specifications feature more flexible parameterization and error distributions than the untransformed models. Using the 1987–88 Nationwide Food Consumption Survey data on household pork consumption, a nonnested test suggests that the IHS double-hurdle model provides better characterization of the data-generating process than the IHS infrequency-of-purchase model but the elasticities derived from these models are similar. Own-price effects on the probability and level of consumption are negative and significant, but the elasticities are small. Income and cross-price effects are not significant. Household age composition, education, gender of meal planner, and race are among the demographic variables that affect consumption.
