FLEXIBLE PRICES: The proposition that prices adjust in the long run in response to market shortages or surpluses. This condition is most important for long-run macroeconomic activity and long-run aggregate market analysis. In particular, flexible prices are the key reason for the vertical slope of the long-run aggregate supply curve. This proposition is also central to original classical theory of macroeconomics and to modern variations, including rational expectations, new classical theory, and supply-side economics.

- Explicit opportunity cost: Out-of-pocket or accounting cost that involves a money payment.
- Implicit opportunity cost: Cost that does not involve a money payment.

The other is a change in real production. A change in aggregate supply is comparable to a change in market supply.
