HC Deb 28 February 1975 vol 887 c286W
Mr. Ralph Howell

asked the Chancellor of the Exchequer to what extent propery values, and in particular disproportionate changes in property values, are reflected in gross domestic product and in the rate of growth of gross domestic product.

Mr. Robert Sheldon

The financial gains or losses resulting from changes in the value of existing assets, including property, are excluded from gross domestic product, since they do not arise from the current output of domestic factors of production.
