Budget Responsibility and National Audit Bill [HL]

Baroness Browning Excerpts

Monday 6th December 2010 Grand Committee

[Baroness Browning]

Will my noble friend confirm that, in the event of the Treasury not using the OBR’s forecast, it will give a full explanation of why it differed from the office’s views?

[Lord Sassoon]

Yes, I can confirm that, although that is not in any way the expectation.

On the specific question of the ITEM Club and the model, the club will no longer have a statutory right to be given a copy of the Treasury model because that arose from the Industry Act 1975, which is being repealed. It will be for the Treasury to consider whether it continues to make the model available, but that will not be a statutory matter any more.

On how the arrangements between the OBR, the Treasury and other parts of government work, that will be set out in the memorandum of understanding, including use of the Treasury economic model, although of course it is entirely at the discretion of the OBR as to what tools, models and methods it uses.

On the question of where the assumptions are to be found, I can certainly find them littered throughout the document published last week, including, for example, table 3.6 on page 67, which as I read it is a mixture of inputs and outputs. There are other assumptions made right through the document.

On the critical question of the approach to economic forecasting raised by the noble Lord, Lord Peston, that is summarised in paragraph 3.7 on page 28. I am glad that people find the Treasury monthly report on the latest independent forecasts useful. It is intended that the Treasury will continue to publish that document and make it available on the Treasury website.

I think that the construct between the Bill and the charter covers all the issues on transparency, something that we all seek, and I suggest that the evidence so far of the OBR in practice means that we should have confidence in that construct. On that basis, I ask my noble friend to withdraw his amendment.

--- Later in debate ---

[Lord Sassoon]

My Lords, there will not be another official internal forecast. There will be the forecast of the OBR, but that does not mean that the Treasury should not have the capability to—and it will—look at underlying assumptions on which the forecast is based, to make sure that it understands where the OBR is coming from and feels comfortable with it. There will not be some other internal official forecast; there will merely be a capability within the Treasury—and it is important that there should be such a capability—whereby Treasury officials can look at and understand the assumptions on which the OBR’s forecast is made. That will not require, and there is no intention for, the Treasury to produce any separate forecast of its own.

[Baroness Browning]

My earlier question came from reading the evidence of Professor Wren-Lewis to the Select Committee. He considered that if,

“the Treasury decides that the OBR model is wrong in some sense, I think basically then it is up to the Treasury to decide whether it wants to move to an alternative model or an alternative way of doing things whereby it produces its own forecast and does not rely on the OBR”.

I understand that the Government accepted that when they responded to the Treasury Committee. That was what prompted my earlier question.

[Baroness Noakes]

Perhaps I may suggest to my noble friend that much of the debate in Committee has been concerned with establishing that the OBR is properly independent of the Treasury. One of the corollaries of having an OBR that is properly independent and that we are all jolly keen to see in a separate building, with staff who are not too intertwined with the Treasury, is that the Treasury will have given away the ability to make some its own appraisals of the economic position. Clearly, it cannot leave itself completely denuded. It would be frankly ludicrous if, in setting up the OBR as a completely independent body to inform the public debate and to be the official forecaster, as my noble friend the Minister has repeatedly said, we left the Treasury with no internal capability to judge for itself whether or not it was happy with what was coming out of the OBR. It would therefore be entirely logical for the Treasury to retain some forecasting capability. In extremis, the Treasury may wish to rest its judgments on its internal forecasts, rather than those produced by the independent OBR, but even without those extreme conditions the Treasury will need to be satisfied that what is coming from the OBR is fit for the purpose of decision-making.
