略论经济增长由单纯依靠投资和净出口向二者与消费协调拉动的转变

在国内持续低消费的情况下,由于政府对投资和出口的过度激励,中国长期以来形成了主要依靠投资、净出口拉动的经济增长。主要依靠投资、净出口拉动的经济增长是不可持续的。实现经济增长主要依靠投资、净出口拉动向依靠消费、投资、净出口协调拉动转变的关键：一在于提高消费,二在于改变政府对投资和出口激励的方式与手段。     

全球失衡问题的资产组合方法——对美国的分析及对中国的启示

基于国际收支货币分析理论的资产组合方法是研究全球失衡问题的一个新视角.这一方法关注一国净外部资产头寸的累积及其可持续性,理解和评估外部失衡的关键是净外部资产变动过程中的价值效应.用该方法对美国外部失衡所做的研究能够得到较为乐观的结论.我国持续贸易顺差并没有带来相应程度的财富累积,我国外部头寸的价值效应为负.我国对贸易顺差进行调整时必须考虑外部头寸价值变动所产生的平衡效应.同时,我国应适当调整外部头寸结构以降低外部财富损失的风险并积极参与东亚金融合作以抵御风险.

Net share issues and the cross‐section of equity returns under a dividend imputation tax system

Despite considerable empirical evidence reporting a negative relationship between net share issuance and subsequent returns, it remains unresolved whether this anomaly is explained by risk or investor irrationality. This study examines the net share issuance anomaly using seasoned equity offerings before and after the introduction of an imputation tax system. We report robust evidence of a negative relationship between net share issuance and returns post‐imputation, but no relationship pre‐imputation. Our results provide evidence to support the international pervasiveness of the net share issuance anomaly, but more importantly suggest that this anomaly may be explained by risk.

The business case of a network that serves both public safety and commercial subscribers

Deploying a single nationwide broadband wireless network to serve all public safety users would have great advantages over the existing fragmented public safety systems. A nationwide system could be created to serve both public safety and commercial subscribers, which would allow a provider to exploit important economies but force it to meet the more costly requirements of public safety. This paper analyzes the viability of a public-private partnership that serves public safety and commercial subscribers from a for-profit provider's perspective. A model is presented that estimates the net present value (NPV) of a wireless network by calculating costs based on the number of cell sites required and revenue based on the projected number of subscribers acquired. The model is applied to both a network that serves only commercial subscribers on 10 MHz of 700 MHz spectrum and a public-private partnership that serves commercial subscribers and public safety personnel on 20 MHz of 700 MHz spectrum. It is found that NPV is greater for the public-private partnership than for the commercial-only network for any population density, which shows that the value of 10 MHz of spectrum exceeds the cost of meeting public safety requirements. Furthermore, the paper demonstrates that NPV/cell increases with population density, so urban areas are profitable and rural areas are unprofitable. The paper demonstrates that a partnership covering 94% of the US population breaks even because the most urban 56% of population subsidizes coverage for the next 38%. If initial deployment is subsidized, a financially sustainable public-private partnership can serve much more than 94%. Additionally, it is shown that allowing urban municipalities to opt-out of the partnership can significantly increase the subsidies required.
