Abstract:
Constant improvement of computing facilities creates a trend to build always larger macroeconomic models. To master these huge and complex models, much effort must be spent to investigate their functioning, mostly by means of simulations or perturbations of their original structure. Such investigations can be greatly facilitated if one has a sound knowledge of the logical structure of the model. This paper presents a graph theory-based methodology that explores the logical implications of a model's specification.
