Nonresponse in Contingent Valuation-reducing uncertainty in value inference

This paper focuses on problems associated with nonresponse in Contingent Valuation surveys. The results from a telephone follow-up survey show that value inference can be considerably improved by information on nonrespondents' attitudes.     

Economic Valuation of Health for Environmental Policy: Comparing Alternative Approaches. Introduction and Overview

Protecting human health is a primary goal of environmental policy and economic evaluation of health can help policy-makers judge the relative worth of alternative actions. Economists use two distinct approaches in normatively evaluating health. Whereas environmental economists use benefit-cost analysis supported by monetary valuation in terms of willingness-to-pay, health economists evaluate interventions based on cost-effectiveness or cost-utility analysis (CEA), using quality-adjusted life-years (QALY) or similar indexes. This paper provides background on the controversy about the relative merits of these approaches and introduces the remaining papers in the special issue. These papers (with one exception) were presented at a conference sponsored by the Department of Economics at the University of Central Florida with support from the US Environmental Protection Agency. Although CEA might not lead to substantially different implications for environmental policy than benefit-cost analysis, and QALY may provide a benefit transfer tool to fill gaps in the morbidity valuation literature, the papers in this issue raise serious concerns about the suitability of QALY-based CEA for environmental regulatory analysis. QALY does not in general appropriately represent individual preferences for health and CEA is neither independent of income distribution nor adequate to assess efficiency.

试析森林生态环境价值计量研究中的几种干扰因素

本文就目前影响在林生态环境价值计量研究的几个干扰因素进行剖析。其中主要包括森林生态环境难以进入市场的原因；在林生态环境资源并不是都重要计量；森林生态环境的价值既是哲学的价值也是经济学上的价值；森林的生态环境转移与它的价值转移没有实现统一；森林生态环境价值计量使用的概念需要明确和统一；在林生态环境资源的监测和统计；影子价格理论在森林生态环境价值计量中应用的合理性；森林生态环境资源生产的投入产出进行过程等问题。这些问题如果得到及时解决，将有助于在林生态环境计量的进一步研究。     

Researching Preferences,Valuation and Hypothetical Bias

A number of recent papers in environmental economics have focused on the process of researching preferences – agents are uncertain about preferences but with effort may narrow their uncertainty. This issue has arisen in formulating bids in contingent valuation (CV) as well as the debate over the divergence between WTP and WTA. In the context of CV, it has been suggested that the hypothetical nature of the preference elicitation process biases responses. This paper provides both a theoretical model and experimental evidence to contribute to this debate. The model is a model of competitive bidding for a private good with two components that are particularly relevant to the debate. The first component is that bidders are unsure of their own value for the private good but may purchase information about their own value (researching preferences). The second component is that there is a probability that the auction is hypothetical – that the winning bidder will not get the private good and will not pay the winning bid. The experiment tests this theoretical model of bidding equilibrium and analyzes the effects of variations in the parameters (hypotheticalness, information costs and number of agents) on the endogenous variables (such as the proportion of bidders who become informed and the winning bid). Experimental results suggest that an increase in the hypotheticalness of an auction tends to decrease the likelihood that bidders pay for information on their valuation with an ambiguous effect on the winning bid.

客户价值的评估方法

关系营销关注的是客户保留,企业要与顾客保持良好的客户关系。作为以赢利为目的的组织,企业很显然应把主要精力放在维护能给企业带来最大利益的客户关系上。本文介绍了几种评价客户关系价值的方法,并讨论了它们各自的缺陷,提出反映客户关系风险水平的经济价值评估法是对客户关系价值的更好的评价方法;同时指出,即使是经济价值评估法也有缺陷,客户关系的总价值应包括经济价值和很难用经济指标衡量的关系利益。最后提出了管理客户关系以最大化客户关系价值的几点建议。
