Sample bias in contingent valuation: A comparison of the correction methods

Abstract

This article compares various methods for correcting contingent valuation aggregate benefits when the sample is known to be biased. A sample is defined as the population, and response rates are simulated on the basis of a measure of salience. The simulated response rates suffer from nonresponse bias and selection bias. Coefficient and benefit estimates that result from weighting and self‐selection correction approaches are compared with the true coefficient and benefit estimates. Our results indicate that at both low and high response rates the standard approach leads to bias, and either correction approach will reduce the bias in coefficient and benefit estimates.     

The differences in hotel selection among various types of travellers: A comparative analysis with a useful bounded rationality behavioural decision support model

This study aims to investigate the hotel selection differences among different types of travellers through online hotel reviews. Specifically, the study performs a detailed examination of the differences in hotel key factors, criterion importance and selection results among five types of travellers, namely, business, couples, families, friends and solo. Using a sample of 194,885 online reviews on TripAdvisor.com, this study identifies the hotel key factors and criterion importance by employing the term frequency-inverse document frequency algorithm and Word2Vec algorithm. Additionally, a bounded rationality behavioural decision support model with picture fuzzy information is proposed to address hotel selection problems for different traveller types. Our results suggest that different types of travellers present differences in hotel key factors, criterion importance and selection results. However, families and friends have similar hotel selection results. This study can serve as a reference for hotel managers in understanding traveller preferences and for tourism website optimisation.     

Perceptions of determinants of job selection in the hospitality and tourism industry: The case of Korean university students

ABSTRACT

This study explores the key factors influencing potential employees in the hospitality and tourism industry and examines whether causal relationships between behavioral attitudes, subjective norms, and perceived behavioral control influence students' job selection. The study suggests that the career decision-making process is related to job selection. A total of 307 responses were analyzed. The results explain individual students' attitudes toward a behavior and perceived behavioral control in the context of their job selection. Attitudes toward a behavior and job selection had significant effects on career decisions. On the other hand, opinions of significant others had no significant effect. Perceived behaviors required to decide on jobs had a significant effect on job selection intentions. Students with internship experience were likely to form positive attitudes toward the hospitality and tourism industry, suggesting internships to be a useful source of a stronger relationship between the industry and job aptitudes of students in hospitality and tourism programs. The results have important implications.     

基于实验人文地理学的旅游目的地选择行为研究

文章基于实验经济学和计算机实验人文地理学的方法思想,以旅游目的地选择行为研究为案例。首先设定研究目标,进而提出了实验的前提假设。采用地理信息科学和网络服务技术,构建旅游目的地选择行为实验平台,展开实例研究,研究结果表明:(1)进行大尺度旅游目的地选择时,被试者表现出不断追求旅游效益最大化这一目标,且与旅游目的地的资源类型无关。(2)被试者经过一定实验学习后,总体上呈现出不断追求个人收益最大化的趋势。然而,有些情况下,也可能出现决策失误。案例研究的成功进一步表明,实验人文地理学思想方法和研究手段对于典型人文地理学问题进行研究是可行的。文章为正在发展的实验人文地理学发展提供了案例指导。     

我国发展循环经济的制度创新策略探讨

有效制度供给不足是造成生态环境问题,引发循环经济的诱因,因此,进行制度创新是发展循环经济的基础和保障;在循环经济的制度创新中,政府应该承担起创新的主体。而在我国,在循环经济的制度创新方式上,应该采用渐变性和激变性相结合的创新方式,在循环经济的制度创新内容应重点对循环经济的法律制度、激励制度、产权制度等进行创新。

采油厂流量仪表选型探讨

流量计的选型直接影响到流量计量的准确度。根据被测介质性质的不同、流量大小和具体的现场条件选择合适的计量仪表,既降低了计量误差,又做到经济耐用,满足了现场计量需要。     

基于交易成本理论的工程合同类型与交易成本探讨

工程合同类型选择问题在工程实践中研究较为广泛,然而对于该问题的更深层次的探讨,特别是在经济学领域的探索却相对较少。在经济学理论影响社会显著发展的当今,应用经济学理论探讨社会经济问题是十分必要的。论文以新制度经济学中交易成本理论研究成果为基础,通过对交易成本的重新理解,分析其与不同合同类型问的联系,得到具有一定指导性的结论,有助于进一步研究和探索。     

项目组合选择研究：基于模糊理论的模型建构及验证

项目组合的选定与企业经营息息相关,然而传统的选择方法存在许多限制。本文应用模糊理论建构一个项目组合的决策模型,模型中纳入了成本、利润及风险等3个决策因子,探讨在资源有限的情况下项目成本及获利的交互影响关系,并利用模糊归属函数建构一个数学规划模型。为了验证模型的有效性,用此模型与传统模型进行求解比较,证实了所提出模型的实用性。
