We explore these questions using a novel measure we call the uncertainty equivalent. We find Expected Utility performs well away from certainty, but fails near certainty for about 40% of subjects. Comparing non-Expected Utility theories, we strongly reject Prospect Theory probability weighting, we support disappointment aversion if amended to allow violations of stochastic dominance, but find the u-v model of a direct preference for certainty the most parsimonious approach UR - https://www.nber.org/papers/w17342 UR - http://dx.doi.org/10.3386/w17342 ER -
