Voting for Environmental Policy Under Income and Preference Heterogeneity
以有机食品为例，研究在收入和偏好异质性下，多数投票者偏好的环境政策（补贴或税收）是否比社会最优更严格，取决于收入差距和社会收益的大小。
Abstract We examine the design of policies for promoting the consumption of green products under preference and income heterogeneity using organic food as an example. Two instruments are considered: a price subsidy for organic food products and a tax on conventional products. When the income differences and social benefits of organic farming are large, these factors dominate in shaping the policy preferences of the majority. In this case, the environmental policies preferred by the majority tend to be stricter than socially optimal policies. However, when income differences are small, policy preferences are more directly determined by tastes for organic products and the majority may prefer no intervention.
