Abstract

We revisit a classical theme of general equilibrium theory, namely the continuity of the Walras correspondence. Using a remarkable theorem due to Fort (Publ Math Debr 2:100–102, 1951) which has widely been used in recent literature on game theory, we prove the generic continuity of the price equilibrium-set correspondence under very general assumptions on the exchange economy.
