Unless disputants understand the meaning attached by each other to the terms of a controversy, they may worry along indefinitely without making an in… - William Trufant Foster

The daily expenditures by consumers for new consumers' goods, upon which business stability largely depends, are determined in part by the total volume of money in circulation, in part by other factors including the frequency with which that money is returned to consumers. The flow of money, therefore, from use in consumption to another use in consumption should not be overlooked in studies of the causes and conditions of business fluctuations. It is the purpose of this paper to describe certain aspects of this circuit flow of money, to raise the question whether it does not deserve more attention that it has yet received in our analyses of business cycles, and to suggest pertinent lines of investigation. Unfortunately, the statistics upon which the most important conclusions concerning this subject must be based are not at hand and are not likely to be for a long time to come. The following discussion will have served its purpose if it stimulates further inquiry in profitable directions and helps to hasten the day when the necessary statistics are available.

At home, as well as abroad, there is paralyzing uncertainty among business men as to whether the Reserve Board will allow that expansion of bank credit without which such prosperity as we have had in recent years simply cannot last. In short, the Board has created a state of mind which breeds business depression.

The double reservoir at the top shows the amount of money in the hands of individuals and available for expenditure in consumption. This is what we have previously called the consumers' fund. The reservoir is divided into two parts in order graphically to represent the fact that a large part of the money received by individuals is income, most of which is spent in consumption; while a smaller part is money received from the sale of real estate, bonds and stocks, most of which is reinvested. The two parts of the reservoir, however, are connected with pipes, in order to take account of the fact that some income is invested and some money received from the sale of securities is spent in consumption. These connecting pipes are important. We must bear in mind that they are always partly, and never wholly, clogged. By their aid, we may visualize the fact that we have no means of knowing how much of the consumers' fund actually will be spent in consumption in any given period of time.
