Multiple Time Series Analysis of Simultaneous Equations Model Specification.

This paper presents an extension of the A. Zellner-F. Palm (1974) methodology using the multiple time series representation of an underlying structural econometric model. The multiple time series approach avoids the problem of cancellation of common factors that has made it difficult to infer structural model characteristics from univariate time series models. In addition the correspondence between the structural model and the multiple time series model provides structural content to the tests for Granger-causality. The approach is illustrated with applications to small macroeconomic models of M. Friedman (1970, 1971) and T. Sargent and N. Wallace (1975).
