"...it’s really important to distinguish between fundamental predictions of a model and predictions that an economist happens to make that don’t really come from the model. The prediction that huge increases in the monetary base will cause large increases in the price level, and that big government deficits will cause big increases in interest rates, are more or less inescapable if your model of the economy is one in which recessions are supply-side problems, not the result of inadequate demand. Conversely, the prediction that neither of these things will happen if the economy is in a liquidity trap is a fundamental prediction of Keynesian models. On the other hand, the unfortunate Romer-Bernstein prediction of a fairly rapid bounceback from recession reflected judgements about future private spending that had nothing much to do with Keynesian fundamentals, and therefore sheds no light on whether those fundamentals are correct."
