“Supply creates its own demand” is the formulation of Say’s law by John Maynard Keynes. The rejection of this doctrine is a central component of The General Theory of Employment, Interest and Money (1936) and a central tenet of Keynesian economics. Say’s law, or the law of market, is an economic principle of classical economics named after the French businessman and economist Jean-Baptiste Say (1767– 1832), who stated that “products are paid for with products” and “a glut can take place only when there are too many means of production applied to one kind of product and not enough to another

Disposable income is total personal income minus personal current taxes. In national accounts definitions, personal income, minus personal current taxes equals disposable personal income. Subtracting personal outlays (which includes the major category of personal (or, private) consumption expenditure) yields personal (or, private) savings.

In economics, a multiplier is a factor of proportionality that measures how much an endogenous variable changes in response to a change in some exogenous variable. For example, suppose a one-unit change in some variable x causes another variable y to change by M units. Then the multiplier is M. In monetary macroeconomics and banking, the money multiplier measures how much the money supply increases in response to a change in the monetary base. The multiplier may vary across countries, and will also vary depending on what measures of money are considered. For example, consider M2 as a measure of the U.S. money supply, and M0 as a measure of the U.S. monetary base. If a $1 increase in M0 by the Federal Reserve causes M2 to increase by $10, then the money multiplier is 10.

Interest rate increase the cost of borrowing, which results in lesser investment activity and the purchase of consumer durables. In a low interest-rate environment, shares become a more attractive buy, raising households’ financial assets. This may also contribute to higher consumer spending, and makes companies’ investment projects more attractive. Lower interest rates also tend to cause currencies to depreciate: Demand for domestic goods rises when imported goods become more expensive. All of these factors raise output and employment as well as investment and consumer spending.

A perfectly competitive industry is comprised of a large number of relatively small firms that sell identical products. Each perfectly competitive firm is so small relative to the size of the market that it has no market control, it has no ability to control the price. In other words, it can sell any quantity of output it wants at the going market price. This translates into a horizontal or perfectly elastic demand curve.
