Relationships among healthy lifestyle beliefs and body mass index in urban China

Consumption is a major driving force in China's economy. The consumer society is particularly emerging in the more urbanized and affluent regions in China. Given the rise of consumerism on the one hand, and the rise of overweight and obesity on the other, this study explored whether the proliferating consumer culture is a threat to the traditional health culture in China. The lifestyle‐oriented approach used in this study does not confirm a straightforward relationship between an upward trend in Chinese with (economic) assets to join the consumer society and a downward trend in health interest among urban Chinese. The result that the rise of the consumer society is not directly accompanied by a devaluation of health issues does not imply that lifestyle research is of no use. On the contrary, this paper successfully identified four dimensions of health‐related lifestyle for urban China, namely Food‐health Belief, Perceived Knowledge, Health Careless and Group Conformity. This result is informative with respect to the complexity of sociocultural factors influencing the increasing prevalence of overweight and obesity.

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.

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.
