Volume of capital services: estimates for 1950 to 2007.

Capital services are the flow of services into the production of output that are generated by the capital stock, as opposed to the stock of capital itself. As such, capital services are the measure of capital input that is more suitable for analysing and modelling productivity. This article presents experimental capital services estimates for 1950 to 2007 for the UK as a whole, for the market sector, and for the non-oil sector. Capital services estimates are also presented by eight asset types and by detailed industry. New estimates for 2007 are presented in this article with earlier years updated to incorporate revisions throughout the time series. Revisions are caused primarily by the adoption of an improved methodology for calculating appropriate plant and machinery deflators and due to the use of an improved purchased software deflator. The main result continues to be strong growth in information and communication technology assets since the mid-1990s, with this growth causing a divergence between the volume of capital services and National Accounts measures of net capital stock.
