基于“善治”理念的我国基本养老保险覆盖面研究

扩大基本养老保险覆盖面必须基于特定的理念进行顶层设计,"善治"理念强调社会公平正义,强调治理主体的多元化,契合了我国基本养老保险制度改革的现实需要。我国基本养老保险领域存在的主要问题在于覆盖面过低,且存在城乡与地区之间在覆盖面和保障水平上的显著差异。从"善治"理念出发,本文提出要充分发挥政府、企业、社会组织及公民个人在扩大基本养老保险覆盖面中的作用,通过不同主体之间的合作实现基本养老保险的全民覆盖。     

国家审计督促国企资产保值增值的功能及其实现路径——基于十九大关于国企与审计管理体制改革要求的研究

以党的十九大提出的国企与审计管理体制改革要求为指导,利用2010—2017年审计署对央企实施审计所提供的自然实验契机,选取商业类央企控股上市公司为研究样本,实证检验国家审计督促国企资产保值增值的功能。在此基础上,进一步从国家审计对国企监督的广度、力度和深度三个维度出发,观察国家审计督促国企资产保值增值的影响路径和作用机理。研究结果表明,国家审计具有督促国企资产保值增值的功能,这种功能的发挥可以通过扩大国家审计对象广度、加强国家审计权限行使力度和提高国家审计目标实现深度来实现。研究结论表明党中央将国企审计监督职权集中赋予国家审计机关的决策是合理的,国家审计机关应当据此优化审计管理体制,努力实现国企审计全覆盖,提高国家审计监督力度和深度,充分发挥国家审计督促国企资产保值增值的作用。

Challenges in service network expansion: An application in donated breastmilk banking in South Africa

Neonatal infections are the leading cause for neonatal deaths in developing countries, resulting in more than 1.5 million infant fatalities annually. The most effective prevention against neonatal infections is exclusive breastfeeding. However, reasons such as maternal death during birth, maternal illnesses such as HIV and TB-meningitis, and lack of rooming-in facilities prevent the infant to be breastfed by his/her mother. One way to mitigate these infections is by supplying pasteurized donor-expressed breastmilk. In this paper, we consider the network expansion of the donated breastmilk distribution supply chain in South Africa. As with the distribution of most public sector and humanitarian relief goods and services, the transportation of donated breastmilk is hampered by the inherent uncertainty in the environment, and by the fact that in addition to efficient usage of resources, distribution should be made in an equitable manner. We incorporate uncertainty into our models by means of multiple scenarios, which are determined based on different assumptions about population size, HIV prevalence, and status of public health in the country, income, and education. We consider various equity-based objectives and propose rounding-based heuristics to solve these. We focus on two delivery schemes; one which uses out-and-back transportation, and one that makes multiple stops on the delivery route. Using computational experiments, we analyze the trade-offs between the objectives as well as the effects of various public health policies, network expansion budget, and assumptions on supply and demand. We also describe the teaching materials resulting from this paper, which include a case study, a supply/demand estimation tool, and an interactive decision support tool.

Interval Estimation of Treatment Effects In Randomized Trials: When do Confidence Intervals Have Nominal Coverage?

In the classical theory of randomized trials (RTs), the treatment effect is defined as a mean difference of potential outcomes. To achieve nominal coverage probability for confidence intervals (CIs) on treatment effects in RTs, certain assumptions are necessary. Specifically, one must either make assumptions about the joint distribution of potential outcomes or enroll subjects in the trial by random sampling of the target population on which the treatment effect is defined. In practice, no such sampling usually takes place and assumptions about the joint distribution of potential outcomes cannot be verified based on observed data. Furthermore, the most common of these assumptions, such as treatment‐unit additivity (TUA) or independence are biologically implausible in most RTs involving human subjects. Hence, it is not usually possible to construct CIs on treatment effects with nominal coverage probability. However, for any joint distribution of potential outcomes, the standard estimator of the variance of the difference of two independent sample means produces CIs with asymptotic coverage at least at the nominal level. This interpretation of CIs as conservative bounds may not always hold in conventional regression models applied to RT data.
