On the boundary behavior of the excess demand function
AbstractI revisit thoroughly the standard boundary behavior satisfied by the excess demand function of a competitive economy, and I prove two implications of the boundary behavior. Then, I show that these implications lead to an alternative proof of the existence of competitive equilibria which is instructive, shorter and perhaps easier than the available proofs in the literature.
