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 FOR GOVERNMENT PURCHASES

The change in government purchases induced by a change in income or production (national income or gross domestic product). The marginal propensity for government purchases (abbreviated MPG) is another term for the slope of the government purchases line and is calculated as the change in government purchases divided by the change in income or production. The MPG plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part of the multiplier process. A related marginal measure is the marginal propensity to consume.
