Heterogeneous preferences regarding global climate change

We examine the structure of preferences for mitigating impacts of global cl imate change that will not occur during the lifetimes of most who are alive today. Because no market data exist for such distant markets, a statedpref erence approach is used. The analysis is based on the random-parameters log it model, and the results indicate substantial heterogeneity in respondent preferences, that mean willingness to pay is a significant and increasing f unction of the scope of the impact, and, provocatively, that respondents ha ve the same preferences over the two very different time horizons that we c onsider.
