Modelling Recreation Demand Using Choice Experiments: Climbing in Scotland

This paper is concerned with the use of thechoice experiment method for modelling thedemand for recreation, using the example ofrock-climbing in Scotland. We begin byoutlining the method itself, including itstheoretical and econometric underpinnings. Datacollection procedures are then outlined. Wepresent results from both nested and non-nestedmodels, and report some tests for theimplications of choice complexity andrationality. Finally, we compare our resultswith a revealed preference data model based onthe same sample of climbers.     

Context-Sensitive Benefit Transfer Using Stated Choice Models: Specification and Convergent Validity for Policy Analysis

Benefit transfer has been an important, practical policy tool appealing to government agencies, especially when time or budget is constrained. However, the literature fails to support convergent validity of benefit transfer using the stated-preference method. This empirical study conducts four convergent validity assessments of benefit transfer using the choice modeling method and data from Rhode Island and Massachusetts, regarding coastal land management. The comparisons evaluate how individual characteristics improve benefit transfer and yield insights relevant to research specifications to produce studies adaptable for transfer applications. Empirical tests show benefit transfer using choice modeling may be acceptable, and even empirically valid, depending on the policy objectives and the context.     

The Simpsons: Public Choice in the Tradition of Swift and Orwell

Abstract: The author disagrees with Homer Simpson who claims that" … cartoons don't have any deep meaning. They're just stupid drawings that give you a cheap laugh." He argues that The Simpsons have a deep meaning in the same way as the works of Jonathan Swift and George Orwell. The message in The Simpsons, Swift, and Orwell is that those in charge do not always undertake action with the public interest in mind—the basic premise of public choice. All three sources provide examples of other public choice themes, and they deliver their message through popular satire with layers of allusion.     

The Role of Age and Gender in Educational Expansion: The South Asian Experience in the Global Context

I calculate education Gini coefficients and decompose the overall degree of educational inequality into age, sex, and within‐group components for 171 countries from 1970 to 2010. Doing so enables me to analyze the distributional outcomes of educational expansion. I use South Asia as a case study, as the education distribution in the region is among the most unequal in the world. Generally, educational inequality is decreasing over the observed sample period around the globe. Yet, as improvements are initiated by enhancing the educational opportunities of the young, the gap between cohorts widens in transition phases but vanishes thereafter. Gaps between the sexes are reduced substantially, but widen if either males or females are the first to enter higher education levels. Also, gaps within population subgroups follow a similar trajectory. Instead of a Kuznets‐curve relation, I thus find evidence for educational inequality to evolve in waves as education expands.

品牌经济学的理论基础——引入品牌的需求曲线及其经济学分析

需求定律是经济学分析的理论基础之一,品牌经济学的理论基础为引入品牌的需求曲线或考虑选择成本的需求定律。把品牌引入经济学中后,品牌信用度的提高使需求曲线右移并变得更为陡峭,同时品牌信用度的提高改变了需求曲线的位置,使得均衡价格提高,均衡数量增加,增加了消费者剩余和生产者剩余,提高了社会福利水平。文章为“品牌战”替代“价格战”提供了理论依据,即通过品牌建设提高品牌信用度,使得在价格提高的条件下需求量增加,而这只有在需求曲线改变位置时方能做到。     

国外审计质量研究思考：需求方和供给方影响

在证券市场中,会计信息质量在保证资源有效配置和市场有效运转方面扮演了重要角色,而审计质量则在相当大程度上决定了会计信息质量。在关于审计质量的研究中,对影响审计质量的需求方和供给方驱动因素的考察则通常被视为审计质量研究的起点。由于我国目前关于该方向的研究尚处于起步阶段,因此本文对20多年来国外相关的研究文献进行了系统回顾和总结,并对国内未来的研究提出了一些具体设想。     

Simultaneous Estimation of Legal and Illegal Supply and Demand: The Case of Motion Pictures

Prior research into illegal goods has typically looked at one-way effects, such as illegal demand on legal demand. This research investigates a previously unexamined component of the market, illegal supply. The authors examine the supply and demand of legal goods and their illegal counterparts as a market system of four interdependent components. This research makes theoretical and empirical contributions by evaluating illegal supply in this system. Simultaneous equations estimate each market component on the others using data from the motion picture industry. The results find illegal supply has no effect on legal supply (movie screens), positive effects on illegal demand (piracy downloads), and some effect on legal demand (box office revenues). Timing effects highlight this: illegal supply has a positive effect on legal demand during a film’s opening week, but no effect post-launch. The other market components have positive effects on illegal supply (except legal supply, which is negative in the opening week). Additionally, illegal demand has a negative effect on legal demand during the opening week of release, but not in the subsequent weeks. This finding alleviates prior research tension as to whether piracy helps or hurts legal sales, as omitting illegal supply could result in biased estimates.     

The economics of education and policy: Ideas for a principles course

There are many aspects of the “economics of education” that would make excellent examples for introductory economics students. The author presents two topics that are central to the economics of education and to human capital theory: the economic benefit (or “returns”) to schooling and educational attainment as an investment. There are two key concepts the author hopes students get from this discussion. The first is that there are both private and social benefits of schooling whence we derive the rationale for government intervention. The second is that educational attainment is an investment decision with both costs and benefits, and some risk.     

The Impact of Letter Grades on Student Effort,Course Selection,and Major Choice: A Regression-Discontinuity Analysis

The authors apply a regression-discontinuity design to identify the causal impact of letter grades on student effort within a course, subsequent credit hours taken, and the probability of majoring in economics. Their methodology addresses key issues in identifying the causal impact of letter grades: correlation with unobservable factors, such as motivation, and direction of causation. They find no evidence that letter grades influence undergraduate students’ course-taking behavior or decision to major in economics. They find that, within a course, the first exam letter grade can affect student performance on the second exam.     

Demand for Piped and Non-piped Water Supply Services: Evidence from Southwest Sri Lanka

In many countries water supply is a service that is seriously underpriced, especially for residential consumers. This has led to a call for setting cost recovery policies to ensure that the tariffs charged for water supply cover the full cost of service provision. Identification of factors driving piped and non-piped water demand is a necessary prerequisite for predicting how consumers will react to such price increases. Using cross-sectional data of 1,800 households from Southwest Sri Lanka, we estimate water demand functions for piped and non-piped households using appropriate econometric techniques. The (marginal) price elasticity is estimated at  − 0.15 for households exclusively relying on piped water, and at  − 0.37 for households using piped water but supplementing their supply with other water sources. The time cost elasticity for households relying on non-piped water only is estimated at  − 0.06 on average, but varying across sources. For both piped and non-piped households, we find evidence of substitutability between water from different sources. We discuss the implications of these results in terms of pricing policy.     

Democratic Choice of an Education System: Implications for Growth and Income Distribution

We use an OLG model to examine democratic choice betweentwo modes of government support for education: subsidies forprivately purchased education and free uniform public provision.We find little conflict between democracy and growth: the samefactors that generate popular support for subsidization overfree uniform provision—large external benefits, a largeexcess burden, and little inequality—also favor its relativegrowth performance. Furthermore, restricting the franchise toan upper-income elite may also reduce growth. Two extensionsexamine the effect of intergenerational mobility and indicatethe theoretical possibility of periodic swings in the balancebetween public and private spending.     

An Analytical Framework for Joint vs Separate Decisions by Couples in Choice Experiments: The Case of Coastal Water Quality in Tobago

This paper offers an analytical framework for analyzing joint and separate decisions by couples in the context of choice experiments for nonmarket valuation. It reports results from an attribute-based stated preference study in which members of couples are asked to conduct a choice-experiment first individually and then jointly. The choice context was the selection of which beach to visit while on vacation in Tobago. Available alternatives differed in attributes related to coastal water and beach quality such as level of coastal development and fish abundance. Tests of preference equality are reported and structured so as to identify the intra-couple decision-making patterns under taste heterogeneity with both finite and continuous mixed logit. Results from the latter suggest that women’s preferences are found to be predominant in the joint choice-experiment. Results suggest caution in using individual choice rather than joint couple choice when valuing quality changes impacting on couple activities, such as water and beach quality in Tobago, and call for further research on the topic.     

Repeated Dichotomous Choice Formats for Elicitation of Willingness to Pay: Simultaneous Estimation and Anchoring Effect

Repeated dichotomous choice contingent valuation data are generated from responses to a succession of binary questions regarding alternative prices for an environmental good. In this paper we propose a simultaneous equation model that allows for endogeneity and error correlation across the responses at each stage of the bidding process. The model allows us to study the evolution of anchoring effects after the second dichotomous choice question. Estimation involves the Bayesian techniques of Gibbs sampling and data augmentation, and the application focuses on the preservation value of a natural area. The results for a data set involving up to four successive dichotomous choice questions show that restricted multiple-bounded models are rejected by the data with the general model. In addition, willingness to pay tends to stabilize after the second stage in the elicitation process for the general unrestricted model. When taking anchoring effects into consideration, it is revealed that individuals’ responses in the latter stages are influenced by the sequence of bid prices offered in earlier questions. Nevertheless, they do not have a significant effect on welfare estimates.      

中国农户融资制度：研究现状、历史变迁与供求非均衡

国内学者关于中国农户融资制度的研究内容和研究成果都比较丰富，但系统研究和动态研究略显欠缺，将制度供求理论引入研究的文献很少。结合中国农户融资制度的变迁及制度变迁理论来看，中国农户融资制度变迁的实质是城市利益导向的金融抑制与金融约束并存的政府管制与操纵，这是导致农户正式融资制度供给不足与过剩并存的、非均衡的政策背景，在这种背景下，制度的设计必然与农户的实际需求背离。     

经济波动同步性、需求冲击与供给冲击——来自海湾国家的实证分析

本文运用结构向量自回归模型,将海湾六国产出的同步波动性和遭受冲击的对称性联系起来。研究发现,1977-2006年间海湾六国遭受需求冲击的对称程度要高于供给冲击,对称性的需求冲击对维持六国经济周期的同步性既显著又重要,而供给冲击的对称性对维持六国经济周期的同步性几乎没有作用;另外,本文没有发现供给和需求冲击的对称性对经济周期的同步波动有滞后影响。本文实证研究的结果对于海湾六国未来单一货币的汇率制度选择具有重要的参考意义。

Preparing Graduate Students in Economics for Teaching: Survey Findings and Recommendations

Survey data from PhD-granting economics departments are used to assess the teaching preparation of graduate students in economics. The results show that relatively few departments require graduate student instructors to take a credit course in teaching before teaching their own course or leading a recitation section. Although more graduate student instructors are required to take a noncredit course in teaching before serving as an instructor or recitation leader, the value of such noncredit courses may be limited. The assessment of teaching preparation by department chairs shows mixed responses, with about three-fifths rating it as very good or good and about two-fifths considering it to be only adequate or poor. Recommendations are offered for improving the teaching preparation of graduate student instructors in economics.     

策略性采购联盟、集体谈判与最优贸易政策选择——基于广义Cournot-Nash谈判函数的分析

文章发展了一个关于由本国企业组成的中间品策略性采购联盟与外国垄断性供给者进行集体谈判的模型一—该模型以中国的制造业外包服务,即出口加工贸易实践为基础,其中,中间品的采购价格与数量通过有效的Nash谈判过程同时决定。当采购联盟的效用函数的数量弹性高于（低于）价格弹性,则该联盟的偏好为数量（价格）导向的。文章证明：（1）当本国与外国的中间品与最终产品贸易具有互补性时,政府贸易政策调整的价格、数量以及福利效应是不确定的,它们依存于本国采购联盟的偏好、最终产品需求曲线的弹性与曲率、外国企业的技术以及生产专业化程度;（2）政府贸易政策的干预功能与企业策略性联盟的自主调整功能存在重叠与冲突。
