Budget
22 June 2010
This document is published for the first time alongside this Budget. It reflects the Government’s commitment to increase transparency around the public finance forecast by publishing the assumptions and methodologies underlying policy costings. This follows the establishment of the Office for Budget Responsibility (OBR), which will provide independent forecasts of the public finances and the economy to inform fiscal policy decisions.
Chapter 1 explains the methodology and general principles for calculating the cost or yield of policy decisions and how they fit within the overall public finance forecast. Chapter 2 includes detailed information on the key assumptions applied in all major policy costings in the Budget. Annex A sets out the indexation assumptions included in the public finance forecast baseline, including all pre-announcements.
'Budget 2010 policy costings' is available in Adobe Acrobat Portable Document Format (PDF). If you do not have Adobe Acrobat installed on your computer you can download the software free of charge from the Adobe website.
