The Logical Structure of a Model

  • Manfred Gilli
Part of the Studies in Contemporary Economics book series (CONTEMPORARY)


This contribution discusses techniques for the investigation of qualitative properties of econometric models. The logical properties of large and sparse systems of equations are efficiently explored by means of graph theoretical tools. Such properties reveal the overall architecture of a model, permitting to better formulate a judgement on the theoretical characteristics and potential applications of the model. It also facilitates the interpretation of particular outcomes and may prove useful in the detection of errors and pitfalls in the model. In many cases this qualitative analysis is also used in strict connection with quantitative investigations such as simulation or the analysis of the dynamic properties of a model.
