Abstract
The specification of an macroeconomic model provides all information needed for a qualitative analysis of the model. Graph-theoretic concepts, like strongly connected components and minimal feedback sets, are used to determine optimal equation orderings and model blocks. Software has been written in order to implement a qualitative analysis of econometric models on basis of graph-theoretic techniques. This software is used to analyse two small theoretical macroeconomic models. Secondly, three empirical large-scale macroeconomic models of the Dutch economy are evaluated. It is shown that an optimal chosen equation ordering may reduce computer time needed for simulation of these large-scale models. The Dutch macroeconomic models, although different at first sight, show some remarkable similarities in model structure.
