We always try to forecast the public finances consistent with how the ONS will measure them once it has implemented its classification decisions, so that our forecasts will be consistent with that eventual treatment. This box outlined the items included in our November 2015 forecast which the ONS had announced, but had yet to implement.
We use a large number of fiscal forecasting models to generate our bottom-up forecasts of the public finances. This box outlined why models are essential forecasting tools, the various types of model used and how their performance is assessed.

The indexation of excise and environmental duties in our forecast
Our forecasts for excise and environmental duties assume that rates are indexed in line with default parameters. These parameters are set by the Government and are detailed at each Budget in the Treasury’s Policy costings document. The assumptions represent a source of economy and
policy-related uncertainty in our forecast. In this box, we looked back at how a selection of duty rates moved over the Parliament relative to the default uprating assumptions assumed in the OBR’s first forecast in June 2010.
