摘要:The classic integrability problem asks (i) what conditions guarantee that demand functions can be rationalized by a well-behaved utility function and (ii) if such a utility exists, how can it be recovered.  Hurwicz and Uzawa (1971) provided answers to both questions.  However for the popular case of changing tastes, as represented by a sequence of non-nested utilities, the Hurwicz and Uzawa conditions fail to hold in general. For given dynamic demands, we provide necessary and sufficient conditions such that the demands can be rationalized by a sequence of utilities following sophisticated choice. The testable implications, including intuitive Slutsky symmetry restrictions, represent a natural extension of those in Hurwicz and Uzawa (1971).  We also give sufficient conditions for rationalizing naive demands.
