Payment and Policy Consequentiality in Dichotomous Choice Contingent Valuation: Experimental Design Effects on Self-Reported Perceptions
研究在挪威减少海洋塑料污染的调查中，随机分配的税额如何影响受访者对支付后果性和政策后果性的自我报告，发现两者随税额变化呈相反趋势，并讨论了后果性感知内生性的处理难题。
Although the contingent valuation literature emphasizes the importance of controlling for respondents’ consequentiality perceptions, this literature has rarely accounted for the difference between payment and policy consequentiality. We examine the influence of a randomly assigned tax amount on consequentiality self-reports and their potential endogeneity using data from a single dichotomous choice survey about reducing marine plastic pollution in Norway. Results show that consequentiality perceptions are a function of the tax amount, with payment consequentiality decreasing and policy consequentiality increasing with higher tax amounts. We discuss the challenge of finding valid instruments to address the potential endogeneity of consequentiality perceptions.
