Does Ambiguity Aversion Raise the Optimal Level of Effort? A Two-Period Model
AbstractI consider two-period self-insurance and self-protection models in the presence of ambiguity that either affects the loss or the probabilities, and analyze the effect of ambiguity aversion. I show that in most common situations, ambiguity prudence is a sufficient condition to observe an increase in the level of effort. I proposes an interpretation of the model in the context of climate change, such that self-insurance and self-protection are respectively seen as adaptation and mitigation efforts a policymaker should provide to deal with an uncertain catastrophic event, and interpret the results obtained as an expression of the Precautionary Principle.
