BUYERS' EXPECTATIONS: One of the five demand determinants assumed constant when a demand curve is constructed, and that shift the demand curve when they change. The other four are income, preferences, other prices, and number of buyers. If buyers expect the future price will be greater, then they're likely to buy more today, to avoid the higher future price. Alternatively, if buyers expect a lower future price, then they're likely to buy less today, awaiting the lower price. A higher future price induces an increase in demand and a lower future price induces a decrease in demand.

SAY'S LAW A principle of classical economics developed the French economist Jean-Baptiste Say that is commonly summarized as "supply creates its own demand." This law, also referred to as Say's "theory of markets" or "law of markets," indicates that the act of producing aggregate output generates a sufficient amount of aggregate income to purchase all of the output produced. This principle indicated that excess production or insufficient demand for production was unlikely to occur, at least for any extended period. When combined with flexible prices and saving-investment equality, Say's law further implied that an economy would achieve and maintain full employment of resources. This law was singled out by John Maynard Keynes in his critique of classical economics, but remains relevant in current macroeconomic analysis, reflected in the circular flow model.
