Using choice experiments to value catchment and estuary health in Tasmania with individual preference heterogeneity*

Choice experiments (CE) have become widespread as an approach to environmental valuation in both Australia and overseas. However, there are few valuation studies that have addressed natural resource management (NRM) changes in Tasmania. Furthermore, few studies have focussed on the estimation of estuary values. The CE study described in this paper aims to analyse community preferences for NRM options in the George catchment, Tasmania. Catchment health attributes were: the length of native riverside vegetation; the number of rare native animal and plant species in the George catchment; and area of healthy seagrass beds in the Georges Bay, which was used as a measure of estuary condition. Mixed logit models with interactions between socio‐economic variables and the choice attributes were estimated to account for systematic and random taste heterogeneity across respondents. Results reveal considerable variation in preferences towards the attributes and show that value estimates are significantly impacted by the way in which we account for preference heterogeneity. Preference heterogeneity thus needs to be considered when estimating community willingness‐to‐pay for environmental changes. This study further shows little responsiveness to the presented changes in estuary seagrass area.     

技术模仿、技术创新的战略选择模型和经济增长

一国技术水平程度的高低在很大程度上影响和决定了该国经济发展的水平和经济增长的速度,技术水平提高的途径主要有两种:技术模仿和技术创新.但技术创新并不只是发达国家的"专利",技术创新除了与人均资本存量和人均人力资本水平有关外,也与总体的人均资本存量和人力资本水平有关.本文将国家技术发展战略分为四类,并给出了各种不同技术发展战略的情景条件.     

美国社会规制研究的三种路径

当西方社会规制研究兴起于20世纪70年代初,除了规制经济学中的公益理论和规制捕获理论影响到社会规制研究外,经济学的成本效益分析、公共选择、政治学的制度主义都渗入到社会规制的研究中.本文主要介绍这三种分析路径在西方社会规制研究中运用,并作出简要的评论.

完善中国商业银行汇率风险管理之对策

随着人民币汇率体制改革和银行业发展进程的加快,国内商业银行的外汇敞口风险、客户外汇风险和折算风险日益显著,汇率风险管理面临着机遇与挑战。国内商业银行应在新的汇率机制下尽快转变风险管理理念,在较为准确地对汇率风险进行识别和计量的基础上,充分利用汇率体制改革深化所创造的有利条件和金融创新的契机,对汇率风险进行主动的控制和管理,最终建立全面的汇率风险管理体系,真正实现获取风险收益的现代商业银行经营模式。     

新媒体时代大学生思想政治教育面临的挑战及对策

随着科技日新月异,新媒体的广泛传播与应用成为社会的主潮流,尤其对当代大学生的学习与生活产生一定影响。新媒体环境下,知识传播呈现出多样性、开放性的特点,大学生获取内容的方式愈发多元化与自由化。同时,传统的思想政治教育不断受到挑战,大学生对于陈旧、平淡的思想政治教育的兴趣逐渐缺失。新媒体的出现吸引了大学生的关注,是具有创新性与时代性的发展。但随着新媒体的革新,大学生在潜移默化中树立了不同的“三观”,使其思想文化与道德素质都发生了巨大改变。因此,在新媒体广泛应用的时代,有效利用新媒体开展大学生的思想政治教育是非常必要的。     

Reports of Bed Bugs on Hotel Selection: A Choice Experiment

The resurgence of bed bugs in the United States creates challenges for hotels and motels. One aspect that is especially important to hospitality are reports of bed bugs and how they affect travellers’ selection and potential damage to hotel brands. To address this issue, we conduct a choice experiment of a national sample of US travellers. We find that consumers expectedly respond negatively to reports of bed bugs, and they are sensitive to the number of reports of bed bugs. Through consumer Willingness to Pay for a hotel room, we quantify the negative impact of reports of bed bugs on the hotel industry through lost room premium. Expectedly, avoiding bed bugs is more valuable among those who worry more about bed bugs, but prior knowledge and experience have no effect. How explicitly the reports of bed bugs are disclosed to travellers affects their reaction and Willingness to Pay greatly.     

选择数量对满意度的影响——一个有调节的中介模型

增加选择数量是否会提高满意度是经济学、心理学和营销学的热点问题。当消费者对某一刺激目标同时存在积极和消极的评价时,即矛盾态度怎样影响选择数量和满意度的关系？2个实验结果表明,选择数量对满意度的影响是通过决策困难水平实现的,当选择数量影响决策困难水平时,会产生选择超载。矛盾态度对决策困难水平与满意度的关系有调节作用,对矛盾态度较高者,选择“多多益善”,选择数量增加使消费者满意度提高;相反,对矛盾态度较低者,选择“适可而止”,选择数量增加使消费者满意度降低。     

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.     

浅析我国政府的危机管理对策

随着全球经济的发展,西方某些学者认为世界正处于一个前所未有的危机频发时期。从现实情况来看,中国人口众多,是一个各种灾难和危机多发的国家。我国政府在危机管理方面积累了丰富的经验。但实事求是地分析,我国政府危机管理体制还不够完善,政府和整个社会的危机管理能力有待提高。对世界具有先进危机管理模式的国家进行分析有助于对我国政府危机管理存在的弊端及体制构建进行探讨。
