摘要
Let X be a compact, or path-connected, metric space whose topological dimension is at least 2. We show that there does not exist a continuous choice i.e., single-valued choice correspondence) defined on the collection of all finite feasible sets in X. Not to be void of content, therefore, a revealed preference theory in the context of most infinite consumption spaces must either relinquish the fundamental continuity property or allow for multi-valued choice correspondences.
