Capital Stock And Capital Consumption Estimates By Industries In The Swedish National Accounts

This paper gives a general description of the principles and methods in connection with making estimates of capital stock and capital consumption in the Swedish National Accounts, with breakdowns into industries and purposes of government services. The first section of the paper deals with definitions, principles and related questions. The major part of the estimates have been made according to the perpetual inventory method. The principles of this method are summarized. A number of problems relating to price indices are also described, as well as problems of valuation of capital for net worth and capital consumption estimates. The second section describes the methods of estimation and sources of data. The calculations have been made on a level of disaggregation into 41 industries and 13 purposes of government services. Three methods are used, i.e., direct estimates for capital objects, where some form of current stock data has been available, insurance values as proxy for replacement values, and perpetual inventory estimates. Comparisons between estimates according to the various methods are made in a number of cases. In the third section a few special problems regarding the quality of the estimates and the possibilities of improving the estimates are explored. The main problems refer to the lack of gross fixed capital formation data, in the form of detailed series which are consistent, cover a long period, and are deflated with an adequate set of price indices. The lack of information on survival curves and durabilities of various types of capital objects is also a severe set‐back. Direct inventories would improve the level of the estimates, but they would also be difficult and costly to undertake. The change in capital stock would in any case have to be determined on the basis of gross fixed capital formation data.
