    Stronger Utility

    Empirical research often requires a method how to convert a deterministic economic theory into an econometric model. A popular method is to add a random error term on the utility scale. This method, however, violates stochastic dominance. A modification of this method is proposed to avoid violations of dominance. The modified model compares favorably to other existing models in terms of goodness of fit to experimental data. The modified model can rationalize the preference reversal phenomenon. An intuitive axiomatic characterization of the modified model is provided. Important microeconomic concept of risk aversion is well-defined in the modified model.Decision Theory, Probabilistic Choice, Stochastic Dominance, Strong Utility, Risk Aversion

    Comment on “A model of probabilistic choice satisfying first-order stochastic dominance” by Pavlo Blavatskyy

    We present examples of existing evidence that lead us to be cautious about claims made in the original paper [Blavatskyy PR (2011) A model of probabilistic choice satisfying first-order stochastic dominance. Management Sci. 57(3):542–548] that the proposed model provides a better fit to experimental data than do existing models. We raise concerns about the accuracy of this and other assertions and about the adequacy of the comparisons made with alternative models in the existing literature
