Jo Michell reminded everyone in a tweet of a quote from Joan Robinson with the comment: “Joan Robinson covered pretty much all of MMT in half a page in 1937.”

It’s a passage from her book Introduction To The Theory Of Employment, pages 72-74 (in the second edition):

CREATION OF MONEY THROUGH A BUDGET DEFICIT

A budget deficit financed by borrowing from the Central Bank has effects similar to those of gold-mining. We have already seen how a budget deficit influences incomes. If there is an increase in government expenditure without any corresponding increase in tax receipts there will be an increase in incomes and activity. This is true equally whether the government borrows from the public or from the Central Bank. If the borrowing is from the public there is no further effect to be considered. But if borrowing is from the Central Bank, then on top of the direct effect of the deficit upon income there is the effect of an increase in the quantity of money. For the Central Bank, in lending to the government, increases the ” cash” of the banks, just as it does by buying securities or by buying gold. The direct effect of the deficit comes to an end as soon as the budget is balanced, but the effect upon the quantity of money remains as a permanent legacy.

The increase in the quantity of money, which takes place cumulatively as long as the deficit is running, will tend to produce a fall in the rate of interest and (unless confidence has been badly shaken) the effects of an increase in investment, induced by lower interest rates, will be superimposed upon the direct effects of the budget deficit in increasing consumption.

At first there will be a drag upon the fall in the rate of interest because the direct effect of the budget deficit in increasing incomes raises the demand for money, since the requirements of the active circulation depend upon the level of income. But the increase in demand for money will be very slight (so long as money wages do not rise) compared to the increase in supply, and it is a once-andfor-all effect, while the increase in the supply of money is cumulative.

…

The whole difference between a budget deficit financed by creating money and one financed by ordinary borrowing lies in this reaction upon the rate of interest.
