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.

IMPERFECT INFORMATION AND THE CHOICE BETWEEN COLLUSION AND HORIZONTAL MERGER

If the payoff obtained by the parties of an agreement depends on the values set for variables the value of which cannot be described precisely or monitored accurately, then the first best outcome may not be achieved. It is shown here that in some cases a second best long term agreement gives the parties a higher payoff, in other cases a short term arrangement is preferred. The interpretation of this result given in the paper is that when a long term contract is preferable, then firms are unable to commit themselves to it through a collusive agreement, and they will try to merge. Vice versa, no need to integrate arises when the preferred second best agreement is the short term one. The last section provides an example, where advertisement effort is non-contractible, while prices are.     

Analyzing online reviews in hospitality: data-driven opportunities for predicting the sharing of negative emotional content

Hospitality is one of the sectors that are nowadays most heavily characterized by consumers’ tendency to share online reviews on dedicated digital platforms. While most past work has focused on understanding the effect of online reviews and ratings on consumers’ evaluation and purchase decisions, this research tackles the issue of what drives the sharing of certain types of online content. Specifically, we investigate the sharing of user-generated content characterized by negative emotional valence, and study the effect of two factors on the extent to which user-generated content contains negative emotions. One such factor is reviewer's expertise, while the other is hotel quality. Our analysis of 1200 TripAdvisor reviews on Italian hotels located in three major Italian cities confirm our hypothesis that expert reviewers might share reviews containing less intense negative emotional content compared to less expert reviewers especially when the hotel is of high quality. To support our hypothesis, we build on the research on psychological antecedents of word-of-mouth behaviour suggesting that expert consumers are particularly reluctant to share negative word-of-mouth to avoid projecting a negative image of themselves in social contexts, thus possibly damaging their reputation.     

Do satisfying walking and cycling trips result in more future trips with active travel modes? An exploratory study

Previous studies have indicated that travel satisfaction - the experienced emotions during, and cognitive evaluation of, a trip - can be affected by travel mode choice and other trip characteristics. However, as satisfactory trips might improve a person's attitude towards the used mode, persons may be more likely to use that same mode for future trips of the same kind. Hence, a cyclical process between travel mode choice and travel satisfaction might occur. In this paper we begin to analyse this process—using a structural equation modelling approach on cross-sectional data—for people who engage in walking and cycling for leisure trips in the Belgian city of Ghent. The focus on walking and cycling reflects recent studies indicating that active travel is often associated with the highest levels of travel satisfaction. Results of this exploratory analysis offer tentative support for the idea of a cyclical process: the evaluation of walking and cycling trips positively affects the respondents' attitude towards the respective mode, which in turn has a positive effect on choosing that mode.

从区位商视角论证构建城镇群的意义——以珠三角、大珠三角和泛珠三角区域为例

随着全球化和区域经济一体化的迅速发展,通过构建城镇群等城市联盟增强区域整体实力已成为提升城市竞争力积极有效的手段。从二十世纪九十年代初期起,先后形成的珠三角、大珠三角和泛珠三角城镇群,通过城市间的资源互补和优势扩散,带动区域整体水平,取得了跨越式发展。本文通过对珠三角、大珠三角和泛珠三角地区不同层次下各城市及区域主要产业就业人口区位商的计算比较,揭示了珠三角区域在制造业方面,大珠三角区域在生产性服务业方面及泛珠三角区域在生活性服务业方面的竞争优势,体现了不同层次城镇群内各行业的竞争发展趋势,由此验证了建立不同层次城镇群的必要性和竞争优势,为区域合作的政策措施提供一定的理论依据。
