第三方仓储物流企业盈利模式探讨

文中主要论述了第三方仓储物流企业三大类共四种不同类型的盈利模式,包括空间仓储服务模式、增值服务模式和基于供需管理平台的服务模式,其中基于供需管理平台的服务模式可分为作为初级阶段管理增值模式和高级阶段的供需网控模式。文中最后还提出了模式转换的建议措施。认为,前两种模式是过去和当前第三方仓储物流企业的主要盈利模式,后两种模式则代表着企业未来的发展方向。     

France in the global economy: a structural approximate dynamic factor model analysis

This study identifies the main shocks that cause fluctuations in French output and their channels of transmission. It uses a large-dimensional structural approximate dynamic factor model. There are three main findings. First, common shocks, especially demand shocks, which seem to originate from the U.S., play an important role in explaining French economic activity. While international trade, relative prices, and foreign direct investment (FDI) flows are the main channels of transmission, the stock market, consumer confidence, and interest rates also matter. Second, France’s integration with the rest of the world has increased over time. Third, there is some tentative evidence of regional components in explaining French output fluctuations; country-specific components also contribute. The predominance of exogenous factors affecting French output, the asymmetry in the transmission of shocks, and France’s participation in a currency area argue for making French goods, services, and labor markets as flexible as possible.     

用窒息价格辅助定价

本文重点阐述了在假定线性需求是合理的以及窒息价格的相关信息可用的情况下计算均衡价格的公式。它能够让分析人员信服,即使在数据非常有限以及缺乏数学支持的情况下,有效的基准计算也是可以实现的。此外,它还有助于阐明价格弹性与需求变化之间的变化趋势,     

民营担保企业运作现状及法律风险问题分析

本着为中小企业提供融资担保服务的宗旨,民营担保企业在致力于实现目标的同时,为解决就业问题、增加国家经济总值和增加税收贡献了不小的力量。由于法律风险防范意识上的不足,民营担保企业面临的法律风险逐渐暴露并呈现扩大趋势。如何能够有效预防法律风险,将其造成的种种损害降至最低,对于担保企业日后发展尤为关键。     

房地产抵押价值评估中被动高估风险的成因分析

2010年以来,中国人民银行和银监会多次提示各家商业银行关注资产泡沫上涨等原因造成的贷款系统性风险,一再收紧银根并加强对存量贷款的风险管理。本文剖析了房地产抵押贷款评估中三个关键概念的混淆,指出这是造成被动高估风险的主要成因。建议重新审视现有抵押评估技术准则,以非公开市场基准下的抵押价值代替市场价值,并更多地考虑成本法和收益法的应用,以防止上述风险在新增房地产抵押贷款中的产生和扩散。     

Estimating consumer willingness to pay for food quality with experimental auctions: the case of yellow versus fortified maize meal in Kenya

Biofortification of maize with provitamin A carotenoids is a new approach to the alleviation of vitamin A deficiencies in Africa. Unfortunately these varieties are yellow or orange, while consumers generally prefer white. Consumer willingness to pay for yellow and fortified maize was compared in experimental auctions in three regions in Kenya. The premium that consumers are willing pay for fortified maize (24%) was higher than the discount they require to buy yellow maize (11%), and in one zone consumers prefer yellow. Yellow color is, therefore, not an impossible obstacle for biofortified maize, although it would clearly be easier to introduce this maize first in regions where yellow maize is currently grown.     

西藏矿产资源及其可持续发展初探

根据西藏矿产资源丰富、地质环境复杂、生态环境脆弱、矿业开发蓬勃发展的现状,针对矿产资源在西藏区域经济发展中所处的地位以及西藏矿产资源开发中存在的对矿山地质环境和矿区生态环境造成不同程度的影响等问题,从推进西藏矿产资源可持续开发的角度出发,贯彻落实科学发展观,走可持续发展道路;科学规划矿业开发布局,合理有序地开发矿产资源;加大找矿力度,进一步摸清西藏矿产资源家底;坚持矿业开发与生态环境保护并重,建设绿色矿山;依靠科学技术,推动矿业健康有序发展。     

A Multi-state model of state dependence in labor supply: Intertemporal labor supply effects of a shift from joint to individual taxation

In this paper I develop an intertemporal discrete choice model of female labor supply to analyze the effects of true state dependence and its effect on labor supply behavior over time. The estimation results show that state dependence is significantly positive at the extensive margin and lower but in general still significant at the intensive margin. I apply this model to study the short and long run labor supply effects of a fundamental reform of the German income tax system, i.e. the shift from joint to individual taxation of married couples and show that labor supply responses are significantly higher in the long run than in the short run.     

Does output have a unit root? New international evidence

In this paper unit-root tests for per capita output of 12 OECD countries are performed. Using traditional unit-root tests, it follows that the unit-root hypothesis cannot be rejected except for the US. However, following the approach of Perron (1989), which takes shifts in mean and/or trend into account, the null hypothesis of a unit-root can be rejected in most countries in our sample. In contrast to Perron, a method suggested by Christiano (1992)is used to determine the break date endogenously.
