Getting consumers to eat more whole-grains: The role of policy, information, and food manufacturers

The 2005 Dietary Guidelines were unique because they offered quantitative recommendations for consumption of whole-grains. This case study examines the hypothesis that the changed recommendations were responsible for the recent increase in retail sales and consumption of whole-grain food products. We find that release of the Dietary Guidelines and related media attention did increase availability and sales of whole-grain foods. A large impact on consumption occurred through reformulation of existing products, induced by competition among food suppliers. This study reveals the key role product reformulation plays in inter-firm competition and in realization of dietary changes recommended by public policy.     

1980-2006年东亚经济波动的原因——基于面板VAR的分析

东亚经济波动及其协同性的存在已得到学术界的认同,文章通过构建面板向量自回归模型,检验了6种冲击对东亚经济波动的影响,并考察了宏观经济各变量在面时冲击时的动态反应,以及汇率和通货膨胀对经济波动的传导作用.研究表明,国内的供给冲击、汇率冲击,国外的利率冲击、需求冲击都会对东亚经济波动产生较大影响,汇率是外部冲击的重要传导渠道,而通胀是内部冲击的重要传导渠道.随着东亚经济一体化进程的推进和金融市场不断开放,东亚各经济体对外部需求变动和世界利率变动所产生的冲击应予以重视.     

城市化水平对城乡收入差距影响的协整分析

改革开放以来,我国的经济发展水平有了很大提高,但城乡收入差距也随之扩大,不利于我国经济建设的稳定发展和构建和谐社会目标的实现.分析了我国城乡收入差距的现状,采用协整检验方法实证研究了城市化发展对城乡居民收入差距的影响,结果表明我国城市化发展扩大了城乡收入差距.在目前我国城市化进程中,应通过加快农村剩余劳动力的转移、大力开展农业技术培训、培育农民的市场意识、积极发展乡村的特色传统产业、鼓励富裕人员和知识分子回乡创业等政策缩小城乡居民收入差距.

Innovation And Inter-Firm Co-Operation: The Case Of The West Midlands

Drawing upon the innovative milieux and industrial districts literature, the paper provides substantial empirical evidence that firms have a greater chance of being innovative if they co-operate with other firms over innovation, albeit undertaking no investment in RLD. This is an important result especially for small firms. In particular, the paper focuses on inter-firm cwperation along the supply chain, using a swey of firms in the West Midlands to investi-gate co-operation over innovation between suppliers and buyers. A probit model is used to test the link between innovation performance and four innovation inputs: R&D expenditure, R&D personnel, networking with suppliers and networking with client firms.

国外临床药学服务的经济学评价文献综述

目的了解经济学评价对于临床药学发展的重要性,以及如何应用评价结果进行临床药学服务方案的调整。方法回顾国外临床药学经济学评价文章,整理产生经济效益的临床药学服务类型、经济学评价的常见方法。结果目前主要应用三种方法对临床药学干预进行经济评价:成本-效果分析、成本效用分析、成本-效益分析;产生经济效益的临床药学服务有节约成本的干预,多学科团队参加查房,药品不良事件的预防,处方差错的预防,抗生素治疗的管理,广泛的临床药学干预等。结论经济学评价对于证明临床药学工作成效、获得政策的支持、提高药学服务质量非常重要。     

The effect of commute time on racial earnings inequality: a case study of the Houston metropolitan statistical area

Data from the United States Census confirm a substantial increase in the racial earnings gap between 1980 and 1990. This paper examines data on whites and non-white wage and salary incomes in Houston TX for 1980 and 1990. Data on time travelled to work is used to simulate what would be the impact of shorter commute times on earnings inequality. The central finding is that a reduction in travel time from residence to work would cause a very small reduction in racial earnings and income inequality. This suggests that advances in urban transportation policy alone are not sufficient to solve the problem of racial earnings inequality.     

我国创业投资的回报率及其影响因素

基于1999年到2003年间我国56个本土创业投资退出项目的数据,本文对我国创业投资退出项目的投资回报率及其影响因素进行了实证研究。结果表明:(1)国有创业投资机构退出项目的平均投资回报率显著低于非国有创业投资机构;(2)创业投资机构的资本规模与回报率呈显著负相关关系;(3)上海、深圳两地创业投资机构退出项目的回报率显著高于其他地区;(4)本土创业投资机构的从业时间、投资规模、投资周期、退出方式均与回报率没有显著相关关系。本文在此基础上提出了相关的政策建议。
