Individual subjective distributions for future climate conditions are combined with stated preference discrete choice data over alternative climate policies to estimate individual option prices (the appropriate ex ante welfare measure in the face of uncertainty) for climate change mitigation. We find significant scope effects in the estimated option prices according to both expected conditions and degree of uncertainty.459776 bytesapplication/pdfen-USOption priceClimate changeStated preferenceContingent valuationState-dependent preferencesPublic economicsMicroeconomicsEconomic historyWorking Paper
