The effects of using different distributions to parameterize the prior beliefs in a Bayesian analysis of vector autoregressions are studied. The wellknown Minnesota prior of Litterman as well as four less restrictive distributions are considered. TWO of these prior distributions are new to vector au

Abstract
This paper shows that vector auto regression (VAR) with Bayesian shrinkage is an appropriate tool for large dynamic models. We build on the results of De Mol and co‐workers (2008) and show that, when the degree of shrinkage is set in relation to the cross‐sectional dimension, the forecasting performance of small monetary VARs can be improved by adding additional macroeconomic variables and sectoral information. In addition, we show that large VARs with shrinkage produce credible impulse responses and are suitable for structural analysis. Copyright © 2009 John Wiley & Sons, Ltd.
