Data-based Misspecification Analysis of a General Equilibrium Model

Summary/Abstract: The paper presents the derivation of structural equations of an estimated general equilibrium model, illustrates techniques of its connection with the data observed and discusses a method of assessing the degree of acceptance by the data. The results suggest that the model is not confirmed by the data. Logarithms of the marginal data density tend to systematically decrease when the weight of the structural model is being increased in hybrid vector autoregression. This defines an econometric tool which can capture a general equilibrium model on the one hand and almost unrestricted vector autoregression on the other. As a consequence of high structural model misspecification, economic conclusions it leads one to draw may be highly inaccurate.
