Implications of Microeconomic Theory for Community Excess Demand Functions
A series of results, related to Sonnenschein’s conjecture that Walras’ Law is the only signiﬁcant restriction microeconomic theory imposes on community demand and excess demand functions are surveyed and extended. These results have important implications for general equilibrium theory, both in questions of existence and stability, and for empirical work.
