Abstract: In this paper we deal with the basic two-period consumption saving problem where the first and second period consumption utility, v and u is assumed to be concave re- spectively as usually. We prove that for the rank dependent utility model, prudence is fully characterized by the convexity of u/ and strong pessimism. The paper ends by showing that for a strong risk averse RDU decision maker, strict pessimism allows local weak prudence, whatever the sign of u/// .
