MONASH-USA (also known as USAGE-ITC) is a detailed dynamic general equilibrium model of the U.S. developed by the Centre of Policy Studies in collaboration with the U.S. International Trade Commission. This paper reports on the theoretical developments completed for a project intended to (a) add...

We propose two algorithms for deciding if the Walrasian 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 compute counterfactual equilibria in applied general equilibrium...

Our paper contributes to bridge the gap between the microsimulation’s approach and applied GE models, by making use of exact aggregation results from the discrete choice literature: heterogeneous individuals choosing (possibly continuous amounts) within a set of discrete alternatives may be...

We develop a method that allows one to compute incomplete-market equilibria routinely for Markovian equilibria (when they exist). The main difficulty to be overcome arises from the set of state variables. There are, of course, exogenous state variables driving the economy but, in an incomplete...

We propose a nonparametric test for multiple calibration of numerical general equilibrium models, and we present an effective algorithm for computing counterfactual equilibria in homothetic Walrasian economies, where counterfactual equilibria are solutions to the Walrasian inequalities.

An extension of the hypothetical extraction method to a general equilibrium setting is considered. This has the advantage of re-interpreting output changes as efficiency gains or losses, which may be of use in identifying “key” sectors in an interconnected economy. The categorization may be...

This paper discusses which changes in the architecture of a standard CGE model are needed in order to introduce effects of trade and firm het- erogeneity à la Melitz. Starting from a simple specification with partial equilibrium, one primary production factor and one industry, the framework is...

In this paper, in homage to Alan Turing’s birth centennial, I try to develop what may be called Turing’s Economics. I characterize the contents of such an ‘economics’ in terms of the conceptual and mathematical tools developed by Alan Turing. It is shown, in more and less detail, how...
