Values, prices of production and market prices: some more evidence from the Greek economy

This paper extends the empirical investigation of the relationbetween labour values and different price forms in the caseof the Greek economy. Subjecting the labour theory of valueto empirical tests with data from various countries helps inthe derivation of general conclusions regarding its empiricalvalidity and practical usefulness. Our results on the closenessof values and prices as measured by their absolute deviationand correlation, the shape of the wage–profit curves,the predictive power of labour values over market prices comparedwith other ‘value bases’, and the comparison offundamental Marxian categories when estimated in value and priceterms provide further support for the empirical strength ofthe labour theory of value.     

Willingness to Pay to Reduce Mortality Risks: Evidence from a Three-Country Contingent Valuation Study

Valuing a change in the risk of death is a key input into the calculation of the benefits of environmental policies that save lives. Typically such risks are monetized using the Value of a Statistical Life (VSL). Since the majority of the lives saved by environmental policies are those of older persons, there has been much recent debate about whether the VSL should be lower for the elderly to reflect their fewer remaining life years. We conducted a contingent valuation survey in the UK, Italy and France designed to answer this question. The survey was administered in these three countries following a standardized protocol. Our results suggest that the VSL is €1.022 million or €2.264 million, depending on whether we use median or mean WTP. The VSL is not significantly lower for older persons, but is higher for persons who have been admitted to a hospital or emergency room for cardiovascular and respiratory problems. Income is positively and significantly associated with WTP. The income elasticities of the WTP increase gradually with income levels and are between 0.15 and 0.5 for current income levels in EU countries. We use the responses to the WTP questions to estimate the value of an extension in remaining life expectancy. The value of a loss of one year’s life expectancy is €54,000 or €163,000.     

旅游资源价值评估问题探析

旅游资源价值评估是目前旅游资源学、资源经济学和环境经济学等学科研究的热点和难点。本文在介绍旅游资源价值评估的理论基础上,回顾了旅游资源价值评估的国内外研究进展,详细介绍了TCM和CVM两种经典评估模型,并在此基础上提出了目前旅游资源价值评估存在的三大问题：第一,旅游资源价值构成体系尚未形成统一的认识,本文在参考已有的价值分类系统基础上,提出了旅游资源价值构成体系；第二,现有价值评估方法有待深入研究,本文指出了旅行费用法(TCM)和条件价值法(CVM)两种经典评估模型的不足；第三,旅游资源价值动态变化的影响因子体系尚未明确。     

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.      

客户关系管理中的价值研究框架分析

价值研究是客户关系管理研究中基础而关键的问题。现有的价值研究多半是基于企业信息完全的假设上的,但是这个假设在实践中往往很难成立。因此很有必要讨论在信息不完全和不对称的环境下价值信息的获取。可以利用信息经济学中的契约设计的原理在信息不对称的环境下获取客户价值信息。

价值工程(VE)作为一种系统化的管理技术,在企业生产和经营管理中都取得了显著的效果。并且随着时代的发展,应用范围将更加广泛。而企业的战略对企业的经营和发展都起着至关重要的作用,特别是在经济全球化的今天,把价值工程理论运用到企业的基本战略管理中,有利于企业提高效益,创造顾客价值、企业价值和社会价值。     

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。
