Draft Budget 2016-17
Okay. Thank you for that. In terms of non-domestic rates income, paragraph 5.4 of the SFC report states: “In the forecasting of buoyancy for the 2015-16 Draft Budget, Scottish Government forecasters used a range of macroeconomic data to justify raising the buoyancy forecast above its historical average. The Commission discouraged this approach as no link between the macroeconomic variables and buoyancy had been formally demonstrated to justify the magnitude of the adjustment.” The following paragraphs say more about buoyancy. Can you give us a bit more of your thinking on buoyancy and how the Scottish Government can improve, shall we say, its forecasting in that area?

There are two aspects to that. The first is the importance of the Best and Kleven work, which Campbell Leith is best equipped to speak to. The other is highl...

Professor Leith
Okay. Last year, the Scottish Government approached the issue of forecasting buoyancy by starting from the long-run average, then it looked at a range of eco...

Thank you for that comprehensive answer. I move on to the additional land and buildings transaction tax, which is new for 2016-17. Paragraph 7.1 of your rep...
Professor Leith
The figures are from the Scottish Government; we are talking through the various adjustments that the Government has made to the underlying forecast. There i...
The Convener

That is fine. In the section of your report entitled “Improving the Forecasting Process”, you say in paragraph 8.2: “data limitations may place a constrain...
Professor Leith
A number of improvements have been made in data availability through the years. For the buoyancy figures, we now have a longer historical time series, albeit...
The Convener

You would also like more emphasis on behavioural responses.
Professor Leith
Yes.
Lady Rice
I will add a footnote to what Campbell Leith said. There might be instances in which it is not possible to get data. For example, at the high end of property...

I will now open out the session. The first colleague to ask questions will be John Mason.
John Mason (Glasgow Shettleston) (SNP)

Thank you for your report, which makes good reading. I picked out a few things on my way through it. Lady Rice mentioned having a protocol. That is referred ...
Lady Rice
I am searching for the right word, which might not be a technical word. The purpose of the protocol is to respond to some conversations that we have had with...
John Mason
SNP
That is helpful. There will probably be an agreement between the commission and the Government, but the protocol will give the commission’s angle on how it v...
Lady Rice
The protocol will set out how we intend to do our work.
Professor Leith
The way in which we develop the protocol will be contingent on the remit that we ultimately get from the Scottish Fiscal Commission Bill and the response to ...
John Mason

I will come back to that later, but first I will turn to other specifics. Paragraph 3.5 on page 8 of the SFC’s report highlights concerns “that the current ...
Professor Leith
The nuts and bolts of forecasting are about discerning what is going on and discerning whether something is a long-term trend or whether there are just cycli...
John Mason
SNP
If a new trend is starting, surely it is impossible to predict.
Professor Leith
There are techniques for identifying time variation in trends, so people can see that a historical trend no longer applies to the current data releases.
John Mason
SNP
So it is a question of picking up a new trend once it has started.
Professor Leith
It depends. In simple statistical models, techniques can be used that allow people to pick up new trends as they develop. The idea is that turning points are...
