Market intelligence Consensus Economic Forecasts There are a wide variety and number of economic forecasts available to policy makers and businesses. HM Treasury produces a summary of these forecasts, from a significant number of organizations including banks, associations, consultancies and credit agencies. These forecasts cover areas such as GDP, Inflation, household expenditure and unemployment, over a variety of time periods. Forecasters generally use econometric models, to provide insight into possible future outcomes. These models will be based upon a number of assumptions, and so the degree to which they vary will inherently be affected by the specification of the model used.

	Output Price Indices The purpose of the Department for Business, Enterprise & Regulatory Reform’s (BERR’s) output price indices for construction work is to enable anyone involved in estimating, cost checking and fee negotiation of construction works to update historical prices using price adjustment indices. For UK based construction works these are known at Output Price Indices. The Output Price Indices are compiled by the Office of National Statistics and lag the trends of tender prices, resources and materials indices. The Output Price Indices reflect the price of all new build construction work undertaken over a given period in time that had been tendered during an earlier period. Separate Output Price Index series are produced for Public Housing, Private Housing, Infrastructure, Public Works, Private Industrial, Private Commercial as well as a combined index for All New Construction. The Output Prices Indices should not be used as a measure of changes in fee levels. This is because the Output Price Indices includes price movements other than those of professional services as well as averaging out regional variations.
