HC Deb 01 March 1985 vol 74 cc323-5W
Mr. Austin Mitchell

asked the Chancellor of the Exchequer to what extent the increase in net exports and expenditure by companies referred to in paragraph 4.04 of his paper on wages and employment would offset the whole of the initial fall in private consumption in his studies and simulations; if he will publish the relevant figures in the Official Report; and if he will set out information predicted by these studies and simulations on the changes in the figures for manufacturing output, investment in plant and machinery, total investment and trade in manufactures.

Mr. Peter Rees

The effects on net trade, company sector and personal sector expenditure, and private consumption in simulations of lower real wages under various assumptions about fiscal and monetary policy are contained in tables A to D of annex B of the recent paper by Treasury officials on "The Relationship between Employment and Wages". The other information requested by the hon. Gentleman is shown in the following table.

Mr. Austin Mitchell

asked the Chancellor of the Exchequer what are the estimated margins of error referred to in paragraphs 4.02 and 4.03 of his paper on the relationship between wages and employment.

Mr. Peter Rees

The margins of error referred to in paragraph 4.02 of the paper can be derived from the estimated standard errors of the employment functions corresponding to the real wage elasticities of -½ and -1. These are contained in the studies by Nickell and Andrews (1983) and Layard and Nickell (1984) respectively. No estimates of the margins of error in simulations of the Treasury model are available.

Mr. Austin Mitchell

asked the Chancellor of the Exchequer what were the elasticities of demand for imports and exports of manufactures used in his simulation of the relationship between wages and employment.

Mr. Peter Rees

In the Treasury model the demand for exports of manufactures is measured by the level of world trade and the demand for imports of manufactures by various domestic activity variables (manufacturing output, stockbuilding, consumers' expenditure on clothing, durable, and other goods, and investment in plant, machinery and vehicles). Details of the elasticity of exports of manufactures with respect to world trade used in the simulation can be found on page 6 of Government Economic Service working paper No. 71, "Her Majesty's Treasury Macro-Economic Model: Supplement to the 1982 Technical Manual". Details of the import elasticities can be found on pages 45 to 48 of "Her Majesty's Treasury Macro-economic Model Technical Manual 1982". Copies of both publications are in the House of Commons Library.

Mr. Austin Mitchell

asked the Chancellor of the Exchequer what is the nature of the increase in company expenditure referred to in table 2 of his paper on wages and employment; and if he will publish a detailed breakdown in the Official Report.

Mr. Peter Rees

The increase in company expenditure referred to in table 2 of the paper on wages and employment consists of investment and stockbuilding. The breakdown is shown below. Columns do not sum to the total because of rounding.

£ billion rounded to nearest 0.1 billion
Year Private sector investment Stockholding
1 0.1 0.1
2 0.7 0.4
3 0.8 0.2
4 0.6 0.1

Mr. Austin Mitchell

asked the Chancellor of the Exchequer whether he will publish in the Official Report a table showing for the items listed in table 3 of his paper on the relationship between wages and unemployment a breakdown for each year covered by the simulation; and if he will add figures for the exchange rate, long-term interest rates, and purchases of gilt-edged stock.

Mr. Peter Rees

Most of the information requested is contained in tables A and C of Annex B in the paper by Treasury officials on "The Relationship between Employment and Wages". Additional information is shown in the following table.

The hon. Gentleman should also note that there is an error in table 3 of the paper. The figure for "Real Wage Bill" in the second column should read -1.4 and not -0.4.
