Market Demand Functions in the CAPM
AbstractWe demonstrate that in a CAPM economy Walras Law and the Tobin Separation Property characterize market demand in finite sets of prices. Consequently, for any number n there exist CAPM economies which have at least n equilibria and hence have n different beta pricing fomulas. It is shown that the lower bound on the number of equilibria, n, is robust to pertubations of endowments.
