This paper describes a practical and conceptually simple iterative method for solving large dynamic CGE models under rational expectations. Details are given for the MONASH model of Australia but the general approach could be applied to a wide range of dynamic models. The method has been...

Consider the following two opinions, both of which can be found in the literature of consumer demand systems: (a) As the real income of a consumer becomes indefinitely large, re-mixing the consumption bundle becomes irrelevant: having chosen the ultimately satisfying budget shares at any given...

To make CGE models realistic, we sometimes need to include inequality constraints (eg, import quotas) or non-differentiable functions (eg, income tax schedules). Both situations may be described using complementarity conditions, which state that either an equation is true or its complementary...

The past few years have seen increasing use of multiregional and intertemporal (that is, forward-looking) applied general equilibrium (AGE) models. These models share the characteristic of rapidly expanding dimensions. Because multilateral trade models increase in size with the square of the...

When a general equilibrium model is solved, there are often a large number of exogenous shocks. The change in each endogenous variable obviously depends on these different shocks. We point out a natural way of decomposing the changes (or percentage changes) in the endogenous variables as sums of...

General equilibrium models are usually represented as a system of levels equations (e.g. in North America) or a system of linearized equations (e.g. in Australia). Either representation can be used to obtain accurate solutions. General-purpose software is available in both cases - GAMS or MPS/GE...
