I hope I have made clear the distinction betweenthe two types of decision which the earning andwealth-owning public is being constantly called on tomake. But however clear we may be about the dis-tinction, it is nevertheless difficult to keep the causesand the results of the two types of decision dis-entangled, since they act and react on one anotherin a most perplexing way. For the amount of savingand the amount of investment, and consequently thedifference between them, partly depend on the price-level of investment-goods relatively to their cost ofproduction; and at the same time the attitude of thepublic towards savings-deposits and other securitiesrespectively may be partly influenced by expectationsas to the price-level of consumption-goods relativelyto their cost of production. In particular, a changein the disposition of the public towards securitiesother than savings-deposits, uncompensated by actionon the part of the banking system, will be a mostpotent factor affecting the rate of investment relativelyto saving and a cause of disturbance, therefore, to thepurchasing power of money.
