Pigou's wealth effect suggests that when the price level falls, consumers feel wealthier and so increase their spending.Another implication of falling prices, however, is that the real value of dollar-denominated debts will increase.For example, if you owe $100, the real value of your debt goes up, and you are worse off.If someone owes you $100, then falling prices make you better off.Now suppose that on average those who borrow money tend to spend a larger fraction of their income than do those who lend money.Will spending rise or fall as a result of a fall in the price level?
