Measuring and Achieving Equity in Multiperiod Emergency Material Allocation

Emergency material allocation is an important part of postdisaster emergency logistics that is significant for improving rescue effectiveness and reducing disaster losses. However, the traditional single‐period allocation model often causes local surpluses or shortages and high cost, and prevents the system from achieving an equitable or optimal multiperiod allocation. To achieve equitable allocation of emergency materials in the case of serious shortages relative to the demand by victims, this article introduces a multiperiod model for allocation of emergency materials to multiple affected locations (using an exponential utility function to reflect the disutility loss due to material shortfalls), and illustrates the relationship between equity of allocations and the cost of emergency response. Finally, numerical examples are presented to demonstrate both the feasibility and the usefulness of the proposed model for achieving multiperiod equitable allocation of emergency material among multiple disaster locations. The results indicate that the introduction of a nonlinear utility function to reflect the disutility of large shortfalls can make the material allocation fairer, and minimize large losses due to shortfalls. We found that achieving equity has a significant but not unreasonable impact on emergency costs. We also illustrate that using differing utility functions for different types of materials adds an important dimension of flexibility.     

Does a universal non-contributory social pension make sense for rural China?

China’s pension reform during the past three decades has allowed a majority of China’s population to be covered by a pension scheme. Of particular note has been the New Rural Pension Scheme (NRPS), a voluntary programme introduced starting in 2009. One goal of our analysis is to assess that pension scheme, using a variety of sources of information including data drawn from recent (2013 and 2015) nationwide China Health and Retirement Longitudinal Surveys (CHARLS). Our analysis involves an exploration of differences between the generosity and structure of the NRPS and other pension schemes currently in place. We also explore the feasibility of reforming the current “quasi-social pension” component of the NRPS by substituting a universal non-contributory social pension pillar. In connection with our assessment of the NRPS, we note the unusually low benefit levels for rural China.

债务融资、债务结构与公司过度投资行为——来自我国上市公司的经验证据

文章以我国A股市场上市公司为研究对象,实证研究了债务融资对过度投资行为的抑制作用.研究发现:我国上市公司普遍存在着严重的过度投资现象,债务融资及其构成特征整体上并未对公司的过度投资行为起到抑制作用.通过进一步按最终控制人性质分组检验发现,债务融资比例与银行借款在国有控股公司不但没起到抑制过度投资行为的作用,反而还恶化了公司的过度投资行为,债务融资比例与银行借款在非国有控股公司中起到了制约过度投资的作用,商业信用和长短期债务在国有与非国有控股公司中仍没起到制约公司过度投资行为的作用.

收入分配公平是一个历史性范畴,它的内涵随生产关系的变化而变化.正确理解我国收入分配的公平,必须搞清楚机会公平与结果公平、收入分配公平与社会主义市场经济的关系,确立初次分配注重效率,再分配注重结果公平的分配范式.在分配中,防止平均主义,保持合理差距,反对两极分化,坚持效率优先、兼顾公平的原则,促进我国生产力的发展,不断提高人民群众的生活水平.     

民营经济的资金需求：陕西个案研究

在对陕西4个地市进行调研的基础上,估算了该省民营经济的资金需求总量,并分析了其资金需求的结构。结果表明,民营经济的资金存在需求总量难以满足和供求结构失衡的矛盾,在目前国有金融体系支持有限的情况下,民营经济对民间资本产生了强烈的需求。因此解决民营经济融资困境的出路在于有效搭建民间资本投入到民营经济的桥梁和通道。
