Abstract
The rationalization of a choice function in terms of assumptions which involve expansion or contraction properties of the feasible set over nonfinite sets is analyzed. Schwartz's results, stated in the finite case, are extended to this more general framework. Moreover a characterization result when continuity conditions are imposed on the choice function as well as on the binary relation which rationalizes it is presented.
