中国：高储蓄、高投资和高增长研究

本文探讨了中国经济发展过程中长期存在的高储蓄、高投资和高增长并存的现象。文章认为：人口红利、工业化、城市化和市场化改革，是造成中国经济“三高”的实体经济因素和体制因素，这些因素并不能由宏观经济政策予以调整。文章最后提出了大力发展直接融资的改革对策。     

高管团队结构对组织绩效的影响研究

文章基于部分上市公司高管治理数据,通过建立回归模型,研究了高管团队的人口特征和知识结构对组织绩效的影响。研究表明：高层管理团队的总人数与企业绩效负相关,过多的高管团队人数容易引致企业内部管理冲突,不利于组织绩效的提升,而团队中工科背景的高管能够为团队决策提供更专业的意见,女性高管在决策中考虑问题比男性更加细致,履历丰富的高管能提出更多的决策方案并对风险有较高的防范意识,因而这三者在高管团队中的比重与企业绩效有显著正相关关系。平均年龄及学历水平高低与企业绩效之间不存在显著相关关系,因此我们要避免片面追求高管团队年轻化、高学历化的误区,文章的研究结论为企业建设和完善高管团队,提升组织绩效提供了参考。     

Adaptive market efficiency of agricultural commodity futures contracts

In this paper we investigate the adaptive market efficiency of the agricultural commodity futures market, using a sample of eight futures contracts. Using a battery of nonlinear tests, we uncover the nonlinear serial dependence in the returns series. We run the Hinich portmanteau bicorrelation test to uncover the moments in which the nonlinear serial dependence, and therefore adaptive market efficiency, occurs for our sample.     

我国企业年金税惠政策的成本和收益精算评估

企业年金个人所得税递延政策于2014年1月1日开始实施,政策调整必然会带来相应的成本和收益。基于我国特殊的人口结构状况,本文通过建立精算模型进行模拟,具体分析税惠政策的实施在未来50年内的成本和收益,并运用成本收益比和覆盖率两个变量进行评价。模拟结果发现：若税惠政策能够促进企业年金发展,使得覆盖率增加,成本收益比会逐渐在16%~17%的水平保持稳定。本文进一步研究了延迟退休政策和死亡率变化对税惠成本和收益的影响。

多哈回合中的农业问题对中国的影响

多哈回合的谈判结果对于多边贸易体制的稳定、经济全球化的进程、贸易自由化给各成员国带来的福利增进而言,具有极其重要的意义。世贸组织承诺,多哈回合要给发展中国家带来真正的好处。作为世界上最大的发展中国家,中国所受到的影响更是引人注目。     

Structural transformation and productivity growth in India during 1960–2010

In this paper, we examine the role of structural change and sectoral productivity growth in explaining the aggregate productivity of India relative to the United Sates during 1960–2010. We set up a simple two sector general equilibrium model and calibrate it to fit the structural transformation of United States. Our calibrated model for India highlights the relative importance of agricultural productivity growth in explaining its slow process of catching up in terms of aggregate productivity. We show that India could have progressed at a much faster rate and closed a substantial part of its aggregate productivity gap if its agricultural sector had grown at a rate at par with the United States. It is India's relative productivity growth in the non-agricultural sector that explains all the recent success in its closing the aggregate productivity gap with the United States. We also found that an elimination of relative distortion in agriculture in India could result into a modest improvement in the aggregate labour productivity.     

Land rights,agricultural productivity,and deforestation

This paper studies the relationship between land tenure for smallholder agriculture and deforestation. We combine high resolution satellite data on deforestation with rich household and commune-level, biannual panel data from Vietnam. We study two margins of tenure security, whether a household has any land title (extensive) and the share of a household’s land held in title (intensive). Using a household-fixed effects model, we find the increases in crop production and land investment associated with holding land title are driven by the intensive margin. We then aggregate the survey data to the commune-level and find evidence that marginal increases in extensive tenure (share of households with any land title) increase deforestation holding constant the average intensive tenure (average share of land held in tenure among those with land title). We find some evidence that increasing the intensive margin of tenure (holding constant the extensive tenure) decreases deforestation. These results present a more nuanced view of the tenure-deforestation relationship than is prevalent in the existing literature.

Population ageing and inflation with endogenous money creation

This paper models a mechanism through which population ageing may induce a deflationary process. We propose an overlapping-generations model (OLG) with money created by credits (inside money) and intergenerational trade. The model links demographic factors, such as fertility rates and longevity, to prices. We show that lower fertility rates lead to smaller demand for credit and lower money creation, which in turn cause a decline in prices. Changes in longevity affect prices through real savings and the capital market. Furthermore, a few links between interest rates and inflation are addressed; they arise in the general equilibrium and are not thoroughly discussed in literature. Long-run results are derived analytically; short-run dynamics are simulated numerically.
