“共同富裕”主题笔谈

扎实推进共同富裕的关键是“提低”，即提高底层人群的收入、财产水平及享有的社会保障和公共服务水平，而其中最重要的是不断提高他们的收入水平。我国公有制经济为主体的基本经济制度要求分配制度以按劳分配为主体，故共同富裕的主要途径是勤劳致富。同时，与公有主体经济并存的各种非公有制经济是中国特色社会主义的显著优势，是推动共同富裕的重要力量。实现共同富裕要正确处理效率与公平的关系，既要把蛋糕做大，又要把蛋糕分好；政府通过再分配促进共同富裕的重点应该是收入流量的再分配，并重视居民可支配收入的提高。共同富裕是对生产力发展和所有制关系的非正义后果的矫正，通过大力解放和发展生产力为实现人类解放奠定物质基础。健全社会保障制度是扎实推进共同富裕的实质性行动。优化完善当前社会保障制度的关键是要改变对社会保障权益的认知。     

策略性补偿下混合渠道下游企业创新激励研究

电子商务环境下,以创新降低物流和库存等分销成本是零售商赢得生存与发展的重要途径,在渠道和谐和利润最大化的双重驱使下,策略性创新补偿成为制造商的首选策略.针对传统零售渠道与在线直销渠道的价格竞争,利用Stackelberg博弈,研究创新投入及其策略性补偿对混合渠道供应链的影响.结果表明,当零售商以创新投入降低其物流和库存等边际分销成本时,制造商将维持批发价和在线直销价不变,零售商将降低传统零售价,制造商和零售商的利润都得到改进;当制造商对零售商实施一定补偿以激励零售商进行更大的创新投入时,制造商将提高批发价并维持在线直销价不变,零售商将降低其零售价并增加创新投入,制造商和零售商的利润将得到进一步改善.因此,创新投入及其策略性补偿能实现混合渠道成员收益的Pareto改进.

Accuracy of Numerical Solutions Using the Euler Equation Residuals

This paper is concerned with asymptotic properties on the accuracy of numerical solutions. It is shown that the approximation error of the policy function is of the same order of magnitude as the size of the Euler equation residuals. Moreover, for bounding this approximation error the most relevant parameters are the discount factor and the curvature of the return function. These findings provide theoretical foundations for the construction of tests to assess the performance of alternative computational methods.     

The Dynamics of Inequality

The past forty years have seen a rapid rise in top income inequality in the United States. While there is a large number of existing theories of the Pareto tail of the long‐run income distributions, almost none of these address the fast rise in top inequality observed in the data. We show that standard theories, which build on a random growth mechanism, generate transition dynamics that are too slow relative to those observed in the data. We then suggest two parsimonious deviations from the canonical model that can explain such changes: “scale dependence” that may arise from changes in skill prices, and “type dependence,” that is, the presence of some “high‐growth types.” These deviations are consistent with theories in which the increase in top income inequality is driven by the rise of “superstar” entrepreneurs or managers.
