Decision Methods for Solving Systems of Walrasian Inequalities
We propose two algorithms for deciding if systems of Walrasian inequalities are solvable. These algorithms may serve as nonparametric tests for multiple calibration of applied general equilibrium models or they can be used to compute counterfactual equilibria in applied general equilibrium models deﬁned by systems of Walrasian inequalities.
