    (Institute for Economic Development, Boston University)

This paper studies consumption/saving problem under Knightian uncer- tainty in a two period setting. The multiple-priors utility model is adopted. The e®ects of income uncertainty and capital uncertainty on optimal savings are analyzed by deriving closed form solutions.
