Rewriting recent history: real GDP revisions
Revisions to National Accounts data are a normal part of the Blue Book process, which reconciles the different measures of GDP and incorporates information from annual data sources. This box explored how the estimated path of the 1990-92 and 2008-09 recessions and subsequent recoveries evolved over time, focusing in particular on revisions to GDP growth in 2011 and 2012.

In each Economic and fiscal outlook we publish a box that summarises the effects of the Government’s new policy measures on our economy forecast. These include the overall effect of the package of measures and any specific effects of individual measures that we deem to be sufficiently material to have wider indirect effects on the economy. In our November 2017 Economic and fiscal outlook, economy forecast adjustments included the effects of looser fiscal policy on GDP, the effects of tax policy changes on inflation and the effects of stamp duty relief for first-time-buyers on house prices.
New UK population projections
The Office for National Statistics (ONS) published new UK population projections in October 2017, based on 2016 population estimates and updated assumptions for fertility, mortality and net migration. This box compared the latest projections with the previous 2014-based principal projections that underpinned our March 2017 forecast and summarised their effects on our November 2017 fiscal forecast.

Near-term giveaways and long-term takeaways
In each Economic and fiscal outlook we incorporate the impact of the policy decisions announced in the Chancellor’s Budget or other fiscal statement (the ‘fiscal event’). This box looked at how measures announced at the previous 16 fiscal events had tended to announce near-term giveaways but with the promise of takeaways in the later years. The Autumn Budget saw this pattern repeated.
A new tax relief for first-time buyers
In Autumn Budget 2017, the Government announced the introduction of a permanent stamp duty land tax (SDLT) relief for first-time buyers. This box considered the effects of a previous temporary relief for first-time buyers and how the new permanent relief was expected to affect tax receipts and house prices.
Local authorities’ net use of reserves (the amount they add to or drawdown from their stock) is a key judgement in our local authority current spending forecasts as it directly affects borrowing. This box outlined recent trends in use of current reserves, split by English authorities with and without upper-tier responsibilities (such as education and social care), which underpinned our November 2017 forecast judgements.
