关于我国推行住房抵押贷款证券化的对策分析

住房抵押贷款证券化是我国未来住房金融发展的必然方向，为了在我国顺利推行住房抵押贷款证券化。应加强培育住房抵押贷款一级市场与投资者，完善相关的法律法规，完善信用评级制度，完善相关的会计和税收制度等。     

刍议初次分配领域公平的内涵

“效率优先、兼顾公平”的大背景下,人们却忽视了与效率密不可分的初次分配领域中的公平问题。我国正处于社会转型期、经济转轨期,要实现又好又快的发展,就必须分析初次分配领域中公平的基本内容,而具体分析初次分配领域中公平与效率的关系。另外,由于初次分配领域中公平本身的不完备性,更需要进一步辨析其与再次分配的差异,以促成分配领域新格局,更好的构建社会主义和谐社会。     

对我国初次分配公平问题的新思考

分配公平应包含分配机会的公平、分配规则的公平和分配结果的公平三层涵义。我国初次分配不公产生的主要原因是分配机会和分配规则不公。解决分配不公的对策是发展教育,实现机会公平;推进经济与政治体制改革和法制建设;完善市场机制;推进城乡一体化。在我国初次分配中注重公平不但不会影响效率．反而会提高效率。     

拆分招标的供应商数量研究

许多企业在采购时,常常将整笔业务拆分为两个合同:较大的第一合同和较小的第二合同,通过分批二级价格封闭式招标来选择不同的供应商供货。本文通过建立分批招标模型分析了供应商的投标策略和买方的采购策略,得出了当参加第一合同竞标的供应商数目和第二合同新引入的供应商数目满足一个不等式时,拆分招标的采购成本小于整体招标的采购成本,并且指出了拆分比例对拆分招标的采购成本的影响。     

人的自由全面发展的相对性研究

在现实中,在范围和程度上,人的自由而全面的发展都具有相对性.作为理想和现实的统一,研究其相对性具有重要的意义.重视每一细微的发展,是通向终极目标的惟一途径.     

Valuing ecosystem services: A shadow price for net primary production

We analyze the contribution of ecosystem services to GDP and use this contribution to calculate an empirical price for ecosystem services. Net primary production is used as a proxy for ecosystem services and, along with capital and labor, is used to estimate a Cobb Douglas production function from an international panel. A positive output elasticity for net primary production probably measures both marketed and nonmarketed contributions of ecosystems services. The production function is used to calculate the marginal product of net primary production, which is the shadow price for ecosystem services. The shadow price generally is greatest for developed nations, which have larger technical scalars and use less net primary production per unit output. The rate of technical substitution indicates that the quantity of capital needed to replace a unit of net primary production tends to increase with economic development, and this rate of replacement may ultimately constrain economic growth.     

资本市场的科学发展之路

资本市场是社会经济的重要组成部分，也要走科学发展之路。根据科学发展观的要求，资本市场不能见物不见人，要以人为本；资本市场要以人为本，投资者关系管理值得推广。资本市场不能玩“富人游戏”，要增进社会福利；切实保证资本市场制度的公开、透明，市场行为的公平、规范，才能促进资本市场的健康发展，推进社会整体福利的增长。资本市场不是孤立的市场，是市场体系中的一部分，要与各类市场协调发展。资本市场不能单打一，要促进经济、社会与自然的和谐统一。     

Cross‐Border Auction Cycle Effects of Sovereign Bond Issuance in the Euro Area

We provide evidence for the euro area of spillovers from foreign public debt auctions into domestic secondary‐market auction cycles. We also confirm existing evidence of such spillovers from domestic issues into the domestic secondary market. Consistent with a theory of primary dealers’ limited risk‐bearing capacity, we find that auction cycles from domestic issues are stronger during the recent crisis period, whereas cross‐border effects are stronger in the precrisis period, but this evidence is not strong. This finding likely reflects the opposing effects of reduced sovereign bond market integration during the crisis and higher yield covariances caused by more market volatility.     

Energy and CO2 emission relationships in the NAFTA trading bloc: a multi-regional multi-factor energy input–output approach

The North-America Free Trade Agreement (NAFTA) has brought together the economies of Canada, Mexico, and the US into forming one of the largest trading blocs worldwide (within the top CO₂ emitters). However, the current global protectionist discourse threatens the agreement. This paper analyzes the energy and energy-related CO₂ emission relationships between NAFTA countries in 2014 to gain insights into the climate change implications of current integration and the possible cancelation of the agreement. The analysis is performed with a multi-regional version of the multi-factor energy input–output model. The results show that NAFTA has not built a single integrated energy system, though it has helped reduce energy-related CO₂ emissions. Moreover, if NAFTA is not revoked, further integration would depend on the capacity of the Mexican energy sector to converge to the performance of its trade partners’ energy sectors. Conversely, a broken deal would induce negative environmental externalities.     

Three‐period,two‐treatment crossover design under long‐term carryover effect

The paper describes non‐parametric approach for analysis of a three‐period, two‐treatment, four‐sequence crossover design in which test procedure for interchangeability of the treatment effects is obtained. The proposed procedure is based on a non‐parametric model, which incorporates, along with the direct treatment effects and the usual carryover effects, the long‐term carryover effects. Relevant competitors are obtained. Related asymptotic results are given. By performing simulation study, we compared the procedures with respect to type I error rate and power. Furthermore, confidence intervals for treatment differences are studied. The procedures are illustrated with a data study.
