货币政策与风险偏好关系研究——基于动态随机一般均衡模型

为了研究中国货币政策与家庭风险偏好之间的关系,在DSGE框架下运用方差分解和脉冲响应等方法分析不同风险偏好条件下利率冲击和货币供给冲击等对中国经济波动的影响;研究结果表明:首先,货币政策方面的冲击解释了中国经济的大部分波动;其次,代表性家庭风险偏好越小,经济对货币供给变动的反应越灵敏。     

Consumer Preferences for Fresh Tomatoes in Benin using a Conjoint Analysis

Constraints related to the technical and socioeconomic aspects of adopting tomato varieties are well documented. However, preferences relating to the demand for this fruit are rarely studied. In fact, demand for the different varieties of tomatoes might be related to consumers’ preferences for the extrinsic (color, size) and intrinsic (taste, nutritive value, water content) characteristics specific to each variety. It is therefore indispensable to determine the characteristics of tomatoes preferred by consumers. We examine consumers’ preferences for tomato attributes among a sample of 600 consumers in four representative markets in the main cities in southern Benin. The study also identifies potential segments of consumers and the market shares of each profile for each segment. The study identifies four potential tomato market segments, two of which have a strong preference for local tomatoes, namely, those that can be conserved for long periods and those with a firm consistency.

Desire for Visual Aesthetics (DVA) in the Store Environment: Concept and Measurement

The article describes the development, purification, and validation of a reliable self-report scale designed to measure the Desire for Visual Aesthetics (DVA) in the store environment. There is limited literature on the subject and a measurement scale has eluded both academicians and practitioners that could help measure the need for aesthetics in the retailing environment and help marketers decide on the level and type of aesthetics for the different segments in the target market/s and also the different type of retail stores. We used 3 focus groups, 8 individual interviews, and 891 surveys to develop, purify, and validate the 9-item Likert type scale. We also provide evidence for dimensionality, reliability, and validity. The scale could be used by academicians and practitioners alike, and could replace single items to measure the concept.     

Crowding standards at Petra Archaeological Park: a comparative study of McKercher's five types of heritage tourists

To achieve sustainability in heritage tourism, tourists should be placed at the heart of the management and planning processes. Indicators and standards-based frameworks were developed in the field of outdoor recreation management to manage and measure crowding and other problematic issues in parks and related areas. Using normative theory and visual research methods, this article aims to examine crowding standards of tourists at Petra Archaeological Park, and compare these standards between the types of heritage tourists suggested by a model developed by Bob McKercher. Results showed that tourists’ acceptability levels go down with an increasing number of tourists, and tourists who are highly motivated to visit heritage sites (i.e. purposeful and sightseeing heritage tourists) had the most restrictive acceptable number of tourists at the park. The normative standards formulated in this article provided a guidance to manage crowding at Petra.

收入因素与中国劣质品市场的部分逆向选择

基于Akerlof逆向选择模型,引入收入因素对其分析,通过说明收入因素影响消费偏好,进而改变消费者的无差异曲线,建立一个有限次交易后最终达到非零均衡的部分逆向选择的基本模型,并着重从这一侧面,即收入因素的影响,分析为什么在中国劣质品市场会长期存在。研究表明：购买偏好因收入增加而改变明显的劣质品的解决途径是增加人们的收入水平;购买偏好随收入增加改变不明显的劣质品的解决途径是增加外部干预。     

Estimating the Private Economic Benefits of Sons Versus Daughters in India

In order to understand the economic incentives behind gender discrimination in India, this paper provides the first estimates of the magnitude of the economic benefits of having a son instead of a daughter. The study estimates large gains from a first-born son to per capita income and expenditure, household assets, and a reduction in the probability the household is below the poverty line. Estimates show that a first-born son may provide economic advantages through a reduction in total children born and also from an adult son’s labor supply contribution to his parents’ household. The observed pattern of incentives is also compared with observed patterns in sex selection as a test of whether the relative economic value of first-born sons and daughters can explain the prevalence of sex-selective abortion.     

银行风险偏好对企业发展影响的实证研究

从行业层面和企业层面实证研究了银行信贷选择对行业和企业发展的影响。结果发现:在行业层面,银行偏好于固定资产比率较高的行业,因此在信贷资源较为紧张的地区,固定资产比率较高的行业会发展得较好,可见长期内银行选择会影响一个地区的产业结构;在公司层面,银行偏好于行业中固定资产比率较高的企业,而企业为了获得信贷资源也会调整其发展策略,倾向于积累固定资产。指出:中国应该大力发展非银行融资渠道,减弱金融系统对经济发展的扭曲。
