HC Deb 15 December 1970 vol 808 c281W
64. Mr. Dixon

asked the Chancellor of the Exchequer what estimates he has made of the marginal propensity to save in his recent reductions of income tax and corporation tax.

Mr. Higgins

The assessment of the demand effects of the tax reductions took into account propensities to save, but it is not customary to publish such assessments.
