The excess demаnd оf аgent i аt price vectоr p in an exchange ecоnomy is defined as z^i(p) = x^i(p) - omega^i, where x^i(p) is their Walrasian (utility-maximizing) demand. Let Z(p) be the aggregate excess demand, i.e., the summation, across agents, of the excess demand. Suppose that preferences satisfy more-is-better. In a two-commodity exchange economy with price normalization p_1 + p_2 = 1 (or equivalently p_2 = 1 - p_1), a competitive equilibrium can be found by solving for the price p_1* such that:
