§ Mr. Austin MitchellTo ask the Chancellor of the Exchequer whether he will publish in theOfficial Report a table showing in terms of 1985 prices the increase in real disposable incomes between 1959 and 1973, 1973 and 1979, and 1979 to date together with (a) the contribution made by (i) the overseas trade surplus/deficit on current account and (ii) the revenue from North sea oil and gas and (b) the annual percentage increase in real disposable incomes in each period less the contribution from (a).
§ Mr. Norman Lamont[holding answer 27 July 1989]: Estimates for real national disposable income (RNDI) at constant 1985 prices for the years 1966 to 1987 are given in table 1.1 of "United Kingdom National Accounts", 1988 edition.
The same table gives estimates, over the same period, for the "terms of trade effect". This is the contribution to RNDI made by changes in export prices relative to import prices. Estimates of the value added by the extraction of 1149W mineral oil and natural gas appear for the years 1977 to 1987 and in current prices in table 2.2 of the same publication; in volume terms expressed as an index with 1985 = 100 they appear in table 2.4.
Longer-run estimates for real national disposable income and for the index number version of value added by the extraction of mineral oil and natural gas are available via the Library of the House which has access to the CSO's computer-readable database.
