Some comments on the Sraffian Supermultiplier approach to growth and distribution

Abstract

The article discusses the Sraffian Supermultiplier (SSM) approach to growth and distribution. It makes 5 points. First, in the short run, the role of autonomous expenditure can be appreciated within a standard post Keynesian framework (Kaleckian, Kaldorian, Robinsonian, etc.). Second, and related to the first, the SSM model is a model of the long run and has to be evaluated as such. Third, in the long run, one way that capacity adjusts to demand is through an endogenous adjustment of the rate of utilization. Fourth, the SSM model is a peculiar way to reach what Garegnani called the “second Keynesian position.” Although, it respects the letter of the “Keynesian hypothesis,” it makes investment quasi-endogenous and subjects it to the growth of autonomous expenditure. Fifth, in the long run it is unlikely that “autonomous expenditure” is really autonomous. From a stock-flow consistent point of view this implies unrealistic adjustments after periods of changes in stock-flow ratios. Moreover, if we were to take this kind of adjustment at face value, there would be no space for Minskyan financial cycles. This also creates serious problems for the empirical validation of the model.     

企业扩张方式与企业短期成长速度关系的实证研究——以资源闲置作为调节变量

文章从知识视角探讨了企业扩张方式，即市场扩张和产品扩张如何与财务资源闲置、人力资源闲置共同影响企业短期成长速度。文章通过100家中国制造业上市公司的数据，对提出的一些假设进行了检验。结果表明，市场扩张方式没有单独对企业短期内的成长速度造成直接影响，产品扩张方式也没有单独对企业短期内的成长速度造成直接影响，并且企业的财务资源闲置对企业扩张方式与企业短期成长速度之间的关系具有调节作用，而人力资源闲置没有调节作用。     

THE AGEING POPULATION: CRUNCH TIME FOR GOVERNMENT REFORMS

Current discussions about reforms to health and long‐term care miss the most important trends that should be influencing debate. With an ageing population that includes a higher proportion of people with manageable illnesses, health and care costs will rise. Reforms must ensure that existing government spending is used more efficiently and that it harnesses – rather than works against – private financing.     

网上商品热销的影响因素探析——基于分位数回归的实证研究

本研究从网上销售的影响因素出发,采用搜索程序获取了淘宝网的4059个货架1周的销售数据,通过分位数回归方法对不同热门程度产品的价格、信誉、保障标记以及口碑的需求弹性进行了实证分析。研究结果表明,随着产品热门程度的提高,信誉的需求弹性不断增强,而价格、保障标记以及口碑的需求弹性却不断减弱。由此表明,产品的价格降低,保障标记级别和口碑的提升都能使销售趋于分散,而提高商家的信誉却能加速销售向热门产品集中,使得"热门更热"。     

High commitment work system,transactive memory system,and new product performance

Although scholars find that the transactive memory systems can improve new product performance, few studies have empirically examined how managers can induce a transactive memory system in new product development teams with a set of systematic management practices. Based on the theoretical argument about human resource system in the strategic human resource management literature, this study proposes that implementing a set of coherent human resource management practices with workers in new product development teams can induce a transactive memory system in the team. Following previous scholars, this study calls this set of coherent human resource management practices as the high commitment work system. With survey data collected from 336 new product development engineers of 73 new product development teams in 73 firms, this study finds that transactive memory system mediates the positive relationship between the high commitment work system implemented with workers in new product development teams and new product performance.

对现阶段中国长期护理保险产品的开发建议

卫生部调查数据显示：中国60岁以上老年人余寿中有2／3的时间带病生存，平均1／4左右的时间处于机体功能受损状态。2008年底，中国60岁以上人口总数达到1．49亿，医疗保障需求极为旺盛，然而，通过保险解决医疗费用支出的比例微乎其微。从中国现行社会保障体系的实际情况出发，结合国外长期护理领域的成熟产品以及中国老年人群的特点和护理需求，对如何做好老年人群的产品规划，促进保险产品创新，提出相应建议。     

埋弧焊在长输管线现场应用的可行性分析

埋弧焊在管线钢工厂生产焊接中取得了很好的应用效果,若把这种焊接工艺引进到长输管线施工现场,将完全打破传统的根焊+热焊+多遍填充+盖面焊的焊接模式,将极大的提高现场施工速度。本文根据埋弧焊原理及特点,通过分析管线钢埋弧焊焊接接头性能,结合长输管线现场施工特点,探讨了管线钢在现场应用的可行性,并提出了埋弧焊在长输管线现场施工中的应用模式。
