Abstract:
This paper investigates public opinion on the Swiss CO2 levy and its 2020 revision by using a discrete choice experiment answered by a sample of 586 respondents living in Switzerland. The experiment is designed to elicit citizen preferences among various taxation attributes and is followed by a referendum voting experiment on various CO2 levy proposals. Based on latent class modeling approaches, we find that the population is composed by two distinct but relatively preference profiles: Environmentalists and Neutrals. Respondents belonging to the first group tend to favor higher carbon tax rates and a redistribution of proceeds benefiting low-income individuals, whereas those in the second group prefer lower rates and a uniform redistribution of proceeds across all taxpayers. Findings from the voting experiment point to a general support among the Environmentalists, but an uncertain approval from the Neutral group.
