Two examples of ambiguity aversion

  • Blavatskyy, Pavlo R.
Registered author(s):

    We consider two plausible and even natural examples of ambiguity aversion: the classical Ellsberg (1961) two-color paradox and a variant of the Machina (2009) reflection example. We extend the results of Baillon et al. (2011) and demonstrate that these two examples challenge the descriptive validity of Siniscalchi (2009) vector expected utility and the model of Nau (2006).
