CONTINGENT VALUATION OF THE PERCEIVED BENEFITS OF FARM ANIMAL WELFARE LEGISLATION: AN EXPLORATORY SURVEY
通过调查人们为支持特定农场动物福利立法的支付意愿，探索条件价值评估方法在动物福利问题上的应用，发现该方法可行但需注意嵌入性、道德满足感购买等问题。
There has been increasing policy debate about farm animal welfare and the need for further legislation in the UK, European Union and, more recently, the USA. However, there is a need for information on the extent to which citizens would wish to support legislative developments intended to improve the welfare of farm animals. The paper describes a survey which explores the application of contingent valuation to animal welfare issues by eliciting people's willingness to pay to support specific farm animal welfare legislation. The findings suggest that contingent valuation may be applied to such animal welfare issues but that studies need to formally address the associated problems of embeddedness, purchase of moral satisfaction and failure of respondents to adequately consider substitute and complementary goods, and their potential effect of overstating willingness to pay.
