This stated preferences survey determines the willingness to pay (WTP) for climate change mitigation policies using a representative sample of the German population. WTP is compared across three valuation question formats in a split sample design: the dichotomous choice (DC) referendum, the dissonance minimizing (DM) referendum and the two-way payment ladder (TWPL). The influence of multinational cooperation on WTP is assessed by variation in the hypothetical scenarios. We demonstrate that the DM referendum and the TWPL, two question formats that induce similar response incentives, yield equal mean WTPs. Multinational cooperation did not change WTP in any of the question formats. Implications for current contingent valuation practice are discussed.
