Is general equilibrium empirically testable?

1 See Chiappori and Ekeland (2004) for a detailed presentation.2 This result directly follows from a revealed preference characterization of excess demand functions.The Weak axiom, for instance, gives q z ( p) 0 p z (q) 0, p, q Obviously, if this property holds true for z, it also holds for z = z if > 0. Extension to the Strong or General axioms is straightforward.
