产业政策中的资金配置:市场力量与政府扶持

产业政策具有重要的国家战略意义,如何有效引导经济资源流向政策支持产业,是产业政策发挥成效的关键.现有相关研究未深入考察经济资源在扶持行业之间及行业内部配置的规律,而且没有综合探讨不同资金配置的关联.文章考察了市场力量与政府扶持两种机制如何引导产业政策下的资金配置.研究发现,产业政策支持的企业获得了更多的债务融资和政府补助.其中,债务融资更多地流向了成长行业中规模较大的企业,政府补助使成长行业中的小规模企业和成熟行业中的大规模企业受益更多.研究结果表明,市场看重企业的增长机会,政府补助则会顾及当前成长性较弱而相对不受市场青睐的企业,对产业政策下的市场化资金配置起到了补充作用.文章的研究为如何协调市场机制和政府扶持两种力量提供了一定的借鉴.     

汇率与股价波动研究——基于中国与日本高频数据的ARCH检验

次贷危机发生前,汇率与股指存在ARCH效应,且均有不对称信息的冲击,波动存在持续性的影响;次贷危机发生后,汇率与股价都不存在ARCH效应,系统性风险和非系统性风险暴露出来使得汇率对股市的波动影响降低,从而促进投资者风险得到有效对坤。     

我国外部均衡调节中的估值效应分析

世界金融一体化促进各国对外资产与负债迅速增长。资产价格的非预期变化使一国对外净资产更多地暴露于资本收益和损失风险中,因此,如何实现有利于一国外部均衡的估值效应就显得日益重要。本文对估值效应的理论模型和计量方法进行梳理,并对我国对外净资产变化中的估值效应进行实证分析,结果发现存在负的估值效应,表明我国通过经常项目盈余所聚积的大量资源正在不断地向国外无偿转移,这就要求对外资产管理水平稳步提高。

Catch Animal Spirits in Auction: Evidence from New Zealand Property Market

Following the animal spirits theory proposed by Akerlof and Shiller, this article contributes to behavior economics by investigating the possibility of using auction sales data to capture evidence of irrational exuberance in the housing market. Using the monthly percentages of residential property auction sales for Auckland, Wellington and Christchurch regions in New Zealand from 2006 to 2015, and the exuberance testing method proposed by Phillips, Shi and Yu, we find that animal spirits have been developing in the Auckland housing market since 2013, but not in other regions. When compared to the results based on price‐to‐rent ratios, auction sales provide more meaningful results for identifying market‐wide irrational exuberance at an early stage. The causality test on price‐to‐rent ratios and auction sales volume shows that asset prices and animal spirits influence each other in the short run. In the long run, prices have significant effect on animal spirits, but not vice versa.     

Health insurance and consumption: Evidence from China’s New Cooperative Medical Scheme

We exploit a quasi-natural experiment arising from the introduction of a health insurance program in rural China to examine how the insurance coverage affects household consumption. Results show that, on average, the health insurance coverage increases nonmedical-related consumption by more than 5%. This insurance effect is observed even in households with no out-of-pocket medical spending. In addition, the insurance effect is stronger in households with worse self-reported health status. These results are consistent with the precautionary savings argument. The insurance effect also varies by household experience with the program. In particular, the effect is significant only in villages where some households have actually obtained reimbursement from the insurance program. The program within these villages stimulates less consumption among new participants than among households that have participated in the program for more than a year.     

试析西方经济学“经济人”假设的发展及其局限性——基于对马克思相关观点的理解

"经济人"假设关注个人的利益目标及实现目标的能力,而马克思在刻画个人时还特别强调了社会关系对个人行为选择的约束。笔者立足于对马克思相关观点的理解,探讨秉承斯密个人主义思想的西方经济学流派对"经济人"假设的继承和发展,试图揭示这一个人观念进一步发展遇到的困惑。遵循方法论个人主义原则,西方学者要从追逐自身利益的"经济人"出发,解释约束其实现自身利益的因素形成和变迁的原因,从而不得不面对引入另一种个人行为模式的尴尬。     

A dynamic perspective: local interactions driving the spread of social networks

ABSTRACT

This study takes a micro standpoint to quantitatively verify the extent to which local interactions affect the expansion of dynamic social networks. By reviewing and synthesizing the theoretical literature in this article, we seek to establish a pragmatic analytical framework to capture the underlying functioning of local interactions. It then aims to produce findings on seven distinct marketing campaigns in which the real-world virtual communities offer intact time-series connections. In our considered cases, the firm-to-consumer interactivity plays a pivotal role in social media marketing while the customer-driven influence advances individual information transmission. The significant positive relationships demonstrate features of interactivity within subgroups including reciprocal edges and directed 3-cliques associated with the evolution of the virtual community by electronic word-of-mouth (WOM) of both firm-to-consumer and consumer-to-consumer interactions. More importantly, the attenuation of local interactions to a large extent leads to the cut-off point of the growth of the dynamic social network.
