Preference Refinement in Deliberative Choice Experiments for Ecosystem Service Valuation
研究在生态系统服务价值评估中引入审议选择实验，通过讨论和反思时间促进偏好精炼，发现审议后选择动机更全面、偏好有所调整且选择确定性略有提升。
Choice experiments have gained considerable popularity in ecosystem service valuation. In a one-shot survey respondents are faced with a strenuous task asking them to discover and monetize their preferences for often unfamiliar ecosystem services in a previously unknown hypothetical market situation. We present a deliberative choice experiment that aims to generate well-rationalized value estimates for policy advice. Two aspects of deliberation— discussion and time to reflect—are examined in terms of their effect on preference refinement. We find more comprehensive choice motives after deliberation, as well as indications for preference adjustment and a slight increase in choice certainty. <i></i>
