Dynamically consistent CEU preferences on f-convex events

We give an axiomatic foundation to the updating rule proposed by Sarin and Wakker [Sarin, R., Wakker, P.P., 1998a. Revealed likelihood and knightian uncertainty. Journal of Risk and Uncertainty 16, 223–250] for CEU preferences. This rule is dynamically consistent but non-consequentialist, since forgone consequences are relevant for conditioning. Whereas it does not work universally, but only when counterfactuals outcomes are better and/or worse than the ones resulting on the conditioning event, the rule has many interesting features, since it is able to describe Ellsberg-type preferences together with a recursive structure of the criterion.
