Comparative Properties of Models of the UK Economy

This paper describes the properties of five major macroeconometric models of the UK economy, through analysis of six standard policy simulations. The simulations are conducted, as far as possible, in a consistent manner across the models. The models were deposited with the ESRC Macroeconomic Modelling in late 1988 and this paper follows comparative analysis of previous model vintages in this Review and in earlier Bureau publications. The paper highlights differences between the models that emerge from the treatment of exchange rates, imports, consumption and price adjustment. Recent changes to the models are shown to have increased simulation differences between them.
