Development and management of a large scale equilibrium model can be much moreefficient if it is broken into its natural, almost independent parts, whichare brought together only when a global solution is desired. We present a newdecomposition algorithm, for non-optimization models of...

The creation and ongoing management of a large economic model can be greatly simplified if the model is managed in separate smaller pieces defined, e.g. by region or commodity. For this purpose, we define an extension of Dantzig–Wolfe decomposition for the variational inequality (VI) problem,...
