摘要

Pigouvian taxes are often unpopular among the general public. We test the effectiveness of pro-tax social information in increasing support for such taxes. In a lab experiment that involves a market game with externalities, we provide subjects with information about other participants’ views about the “right thing to do” (voting, or not, for the tax policy). We also elicit personal, normative, and positive beliefs. Our findings demonstrate a causal effect of social information provision on subjects’ support for the tax, and that subjects’ changes in beliefs is a causal mechanism through which this increased support for the tax is made possible. We therefore highlight the important role of beliefs in voting behaviors and the acceptability of Pigouvian taxes.
