Global environmental phenomena like climate change, major extinction events or flutype pandemics can have catastrophic consequences. By properly assessing the outcomes involved - especially those concerning human life - economic theory of choice under uncertainty is expected to help people take the best decision. However, the widely used expected utility theory values life in terms of the low probability of death someone would be willing to accept in order to receive extra payment. Common sense and experimental evidence refute this way of valuing life, and here we provide experimental evidence of people's unwillingness to accept a low probability of death, contrary to expected utility predictions. This work uses new axioms of choice defined by Chichilnisky (2000), especially an axiom that allows extreme responses to extreme events, and the choice criterion that they imply. The implied decision criteria are a combination of expected utility with extreme responses, and seem more consistent with observations.
⺠We consider death as a catastrophe, namely a rare event with major consequences. ⺠We provide experimental evidence of people's unwillingness to accept a low probability of death. ⺠This experimental evidence is contrary to expected utility predictions. ⺠We argue that this is because EU is unable to explain responses to catastrophic events. ⺠We propose a theoretical framework more appropriate than EU for valuing human life.
