公共住房项目PPP模式研究

公共住房建设是政府实现住房领域公平目标的重要手段,但由于其社会福利属性,面临着资金来源不足、后续发展乏力的困境。文章将普遍应用于国内外基础设施领域的PPP模式引入公共住房建设领域,对PPP模式的中国公共住房项目进行内部、外部条件分析,论证研究的可行性;在此基础上结合经济适用房与廉租房的不同特点探索具体操作形式;对保障高效合作的运行机制进行探讨,以推进城镇公共住房建设发展。     

Do development projects crowd-out private sector activities? Evidence from contract farming participation in Northern Ghana

Contract farming (CF) is attractive as a possible private sector-led strategy for improving market coordination and smallholder farmers’ welfare. At the same time, governmental and non-governmental development projects aimed at improving farmers’ welfare continue to be organized. It is not uncommon for CF activities and development projects to take place in the same communities. Yet so far there is no evidence on how development projects affect CF activities. We examine factors affecting entry in and exit from different maize CF schemes in Northern Ghana, and focus specifically on the role of development projects. We find that the presence of agricultural development projects in the community is associated with lower scheme entry, but this not the case for non-agricultural projects. CF exit is more strongly associated with maize projects, but not significantly with non-maize or non-agricultural projects. Thus, our findings do not support concerns of a general moral hazard problem arising from the presence of any development project, but indicate possible negative associations of more closely related agricultural or maize projects with maize CF participation.     

The impact of exchange rate deviations from relative PPP equilibrium on the U.S. demand for foreign equities

Applying fixed-effects panel data, this study investigates the impact of U.S. dollar exchange rate movements during different exchange rate states (overvaluation and undervaluation) on the monthly real gross and real net purchases of foreign equities by U.S. residents over the post-Plaza Accord period. The foreign equities come from 22 developed and 25 developing countries. Previous research has posited two alternative hypotheses regarding the relationship between exchange rates and foreign investment. These are the wealth effect and the profit-oriented effect. The evidence herein suggests that these two hypotheses coexist. We find robust evidence for a negative relationship between the exchange rate movements of an undervalued U.S. dollar and the demand for foreign equities. For developed countries, the wealth effect dominates the profit-oriented effect when the U.S. dollar is overvalued, while, for developing countries, the profit-oriented effect dominates the wealth effect. The results emphasize the importance of considering exchange rate states derived from a relative PPP equilibrium when analyzing U.S. allocations to foreign equities. The findings with respect to the macroeconomic control variables are mainly in agreement with the predictions of international financial theory. Some of the results, however, disappear or become inconclusive for the period after the bankruptcy of Lehman Brothers. This may be explained by the increased uncertainty in international financial markets following this unprecedented event. The findings are robust with respect to different constructed equilibrium exchange rates.     

我国物有所值定量评价方法有效性检验——基于北京地铁四号线的研究

文章详细介绍了我国公共部门和社会资本合作关系的物有所值定量评价方法,包括概念的解析和具体的公式计算,并运用成功的PPP项目案例对所提到的定量评价方法进行检验。结果证明我国的物有所值定量评价方法在一定范围内是有效的,可还存在计算主体不清导致的计算因素虚增和潜在风险识别不足等问题,建议在实务中要谨慎运用,必要时可借助定性和定量、VFM和其他评价方法相结合的方式来进行决策判断。     

基于协议代理模式下IT外包项目博弈研究

互联网经济的出现致使全球信息化水平向更高级的智能化延伸。IT外包项目对现代企业的作用毋需置疑。本文通过建立了IT外包公司与地方系统集成商间单委托—代理博弈模型,分析了双方间的IT外包项目分包费率和努力程度取值范围,并讨论了IT外包公司和地方系统集成商的行为选择。对IT外包项目的博弈分析结果对于信息化建设企业未来在外包决策时进行风险控制具有一定的借鉴意义。

关于政府投资项目造价控制的问题及策略

政府投资建设项目不同于一般的企业投资项目,多以公益和必要设施为主,但是由于经手部门多、结构复杂等原因,在工程造价控制上面临许多问题,不仅浪费资源、资金,同时不利于廉政建设,也会缩减其他方面的财政支出,因此合理控制政府投资建设项目工程造价成为一个广受重视的问题。
