Description: Dr. Lange will discuss the meaning of Weitzman's (2008) dismal theorem, and demonstrate that his indicator of marginal expected rate of substitution is of limited relevance for cost-benefit analysis: cost-benefit analysis under uncertainty must jointly consider marginal willingness and the options/technologies of transferring income. Dr. Lange's approach shows that an infinite expected marginal willingness to substitute between today's and future's consumption does not generally jeopardize cost-benefit-analysis.
