Average male manual earnings have been assumed to increase by 9¾ per cent. between 1980–81 and 1981–82 and by 7½ per cent. between 1981–82 and 1982–83, taking 1980–81 as the average of 12 monthly estimates derived by interpolating between the figures for manual earnings given by new earnings surveys for April 1980 and April 1981 in line with movements in the average earnings index for the whole economy. Corresponding assumptions for retail prices are increases of 11½ per cent. and 9 per cent. respectively.
