Conventional regression techniques and non-cointegrated VARs. The following were the major alternative approaches to modeling up until, say, 1990: 1.1 Large scale macro models that typically involve: i. distinguishing exogenous and endogenous variables; ii. imposing restrictions of short run dynamics to achieve identification; iii. estimation usually by OLS or IV and are used for simulations. Examples are Fed Reserve Bank Model, Reserve Bank of Australia Model, Chris Murphy Model of Australian economy, London Business School Model, Fair Model of the US economy. 1.2 Nonintegrated VAR Models: Unrestricted, Bayesian and Structural VAR forms: i. Unrestricted VAR is frequently used in short run forecasting and hypothesis testing for Granger causality but it has limited use in policy simulations; ii. Bayesian VAR by definition predetermine structure through prior ordering of variables, ranking from most endogenous to exogenous by design it is researcher fixed.
