We demonstrate that in a CAPM economy Homogeneity, Walras' Law, and the Tobin Separation Property characterize market demand on finite sets of prices. Consequently, for any numbernthere exist CAPM economies which have at leastnequilibria and hence havendifferent beta pricing formulas. Endowment perturbations in these economies cannot decrease the number of equilibria belown.Journal of Economic LiteratureClassification Numbers: C62; D51; D52; G12.
