We propose two algorithms for deciding if theWalrasian equilibrium inequalities are solvable. These algorithms may serve as nonparametric tests for multiple calibration of applied general equilibrium models or they can be used to computecounterfactual equilibria in applied general equilibrium...

This paper discusses the testable implications of the Walrasian hypotheses: H1 Observed market demand is the sum of consumer's demands derived from utility maximization subject to budget constraints. H2 There exists an observable (locally) unique equilibrium price system such that the observable...

This paper introduces habit formation into an otherwise standard model of international trade. Household tastes evolve over time to favor foods consumed as a child. The opening of trade causes preferred goods to rise in price, as these were relatively inexpensive in autarky. Neglecting the...
