A preference is invariant with respect to a transformation if its ranking of acts is unaffected by a reshuffing of the states under. We show that any invariant preference must be parametric: there is a unique sufficient set of parameters such that the preference ranks acts according to their...

This paper conducts a laboratory experiment to assess the optimal portfolio allocation under quantile preferences (QP) and compare the model's predictions with those of the expected utility theory using a mean-variance (MV) utility function. We estimate the risk aversion coefficients associated...

This paper studies the dynamic quantile model for intertemporal decisions under uncertainty, in which the decision maker maximizes the τ-quantile, for τ ∈ (0, 1) of the stream of future utilities. We present two sets of contributions. First, we generalize existing results in directions that...
