Summary
We analyze the choice of a risk-averse decision maker who faces two lotteries that exhibit a trade-off between a reduction in the probability of a loss occurring and its magnitude. We make a theoretical analysis with skewed binary lotteries: lottery L̃ <sub>A</sub> is associated with a lower magnitude and a higher probability of a loss occurring than lottery L̃ <sub>B</sub> . We show that any risk-averse decision maker will prefer L̃ <sub>A</sub> to L̃ <sub>B</sub> when the expected gain of L̃ <sub>A</sub> is higher than or equal to the expected gain of L̃ <sub>B</sub> . However, in the opposite case, additional assumptions on individuals' prudence are required. We experimentally test our theoretical predictions, and provide applications and policy recommendations.
