How Deliberation Affects Stated Willingness to Pay for Mitigation of Carbon Dioxide Emissions: An Experiment
通过实验比较了有/无小组讨论下受访者对二氧化碳减排的支付意愿，发现商议不影响均值或中位数，但改变了受访者考虑的因素，表明普通公民能提供有效的环境政策意见，但传统调查的框架效应可能阻碍这一点。
Respondents reported willingness to pay (WTP) for mitigating carbon dioxide emissions after structured group discussion or without this deliberation. Deliberation did not affect mean or median WTP, but it increased the number of issues respondents considered, with some issues becoming more frequently considered and others less. Survey-only respondents considered issues relevant for responding to a request for a charitable contribution; group-mode participants considered issues relevant for a public policy assessment. Findings suggest that ordinary citizens can offer valid input to environmental policy decisions, but that framing effects in ordinary WTP surveys may prevent them from providing such input. <i></i>
