Data for: The role of question format for the support for national climate change mitigation policies in Germany and the determinants of WTP
Abstract of associated article: This contingent valuation survey examines the willingness to pay (WTP) for climate change mitigation in Germany. Willingness to pay is assessed by using a classic dichotomous choice referendum format and a two-way payment ladder in a split-sample design. We find that mean WTP under the referendum format is more than twice the WTP in the payment ladder format, but median WTP does not differ. Moreover, we test the possible effect of different determinants on WTP. Determinants that considerably influence WTP are personal norm, climate change scepticism, agreement with the German Renewable Energy Law and individualistic cognition. Income and gender are also important predictors.
