Budget Responsibility and National Audit Bill [HL]

My Lords, I understand the argument of the noble Lord, Lord Burns, and I should like to think further about what has been said on this issue. Perhaps I may raise a further point in relation to the model. Over the past 80 or 90 years, we have had a huge difference of view as to whether one should adopt a Keynesian or a monetarist approach to these problems. My impression is that the OBR now has an essentially Keynesian approach and that the monetary aspect does not appear in the discussion at all, other than to say, ““Well, of course, the Bank of England is targeting inflation””, and let it go at that. However, as I have previously pointed out to the noble Lord, Lord Myners, and others, until we got into quantitative easing the Bank was concerned purely about the price of money—the rate of a single rate of interest—rather than the quantity of money. I am not the least bit clear about the proposal as it now comes here and to what extent the OBR is taking monetary factors into account. Let me illustrate this by giving an example from many years ago. I am delighted to see that the basic approach to economic forecasting on page 28 is to decide on how much excess capacity there is and then to see to what extent aggregate demand gradually increases and absorbs that excess capacity. That was precisely the policy that we adopted in 1970 under the Heath Government. We said then, in the clearest terms, exactly what is being said now on page 28. Unfortunately, this was misinterpreted as a dash for growth and we were absolutely pilloried by those who said that the money supply had been going up very fast. In fact there was a big difference between the money supply, the money supply figures and what was happening to aggregate demand. The point that I am seeking to make is that this does not take into account the effect of quantitative easing, for example, or, if it does, I am not clear where that would appear in these forecasts, although no doubt the Minister can enlighten us. Given that we are told that the Bank of England is going to make yet a third, quite different, forecast in addition to the, I am almost inclined to say, surreptitious one in the Treasury—I accept fully the point made by the noble Lord, Lord Burns—I am worried that the fiscal and monetary side is not sufficiently integrated in the forecasts.
