BARTER ECONOMY: An economy that trades goods and services using barter exchanges rather than money. Barter economies originally predated the invention of money, emerging out the early stage of self-sufficiency before giving way to the use of commodity money. However, barter economies occasionally surface in modern times, especially when the public loses confidence in the monetary unit during a government crises or a period of hyperinflation.

MARGINAL PROPENSITY TO IMPORT The change in imports purchased from the foreign induced by a change in income or production (national income or gross domestic product). The marginal propensity to import (abbreviated MPM) is another term for the slope of the imports line and is calculated as the change in imports divided by the change in income or production. The MPM plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part to the multiplier process. A related marginal measure is the marginal propensity to consume.
