Equilibrio walrasiano en econom?as de intercambio

We present the aggregated excess demand functions in an exchange economy. We study the properties and the equilibrium price vector of the aggregated excess demand functions. We prove that the walrasian equilibrium is a Pareto optimun. We study regular ecomies. We prove the existence of regular equil...

Summary: We present the aggregated excess demand functions in an exchange economy. We study the properties and the equilibrium price vector of the aggregated excess demand functions. We prove that the walrasian equilibrium is a Pareto optimun. We study regular ecomies. We prove the existence of regular equilibrium for regular economies. We study the unicity of the equilibrium price vector.
