It may be objected that government expenditure financed by borrowing will cause inflation. To this it may be replied that the effective demand created by the government acts like any other increase in demand. If labour, plants, and foreign raw materials are in ample supply, the increase in demand is met by an increase in production. But if the point of full employment of resources is reached and effective demand continues to increase, prices will rise so as to equilibrate the demand for and the supply of goods and services. (In the state of over-employment of resources such as we witness at present in the war economy, an inflationary rise in prices has been avoided only to the extent to which effective demand for consumer goods has been curtailed by rationing and direct taxation.) It follows that if the government intervention aims at achieving full employment but stops short of increasing effective demand over the full employment mark, there is no need to be afraid of inflation.[*]
[*]Another problem of a more technical nature is that of the national debt. If full employment is maintained by government spending financed by borrowing, the national debt will continuously increase. This need not, however, involve any disturbances in output and employment, if interest on the debt is financed by an annual capital tax. The current income, after payment of capital tax, of some capitalists will be lower and of some higher than if the national debt had not increased, but their aggregate income will remain unaltered and their aggregate consumption will not be likely to change significantly. Further, the inducement to invest in fixed capital is not affected by a capital tax because it is paid on any type of wealth. Whether an amount is held in cash or government securities or invested in building a factory, the same capital tax is paid on it and thus the comparative advantage is unchanged. And if investment is financed by loans it is clearly not affected by a capital tax because if does not mean an increase in wealth of the investing entrepreneur. Thus neither capitalist consumption nor investment is affected by the rise in the national debt if interest on it is financed by an annual capital tax.
