SCARCITY RENT: The marginal opportunity cost imposed on future generations by extracting one more unit of a resource today. Scarcity rent is one of two costs the extraction of a finite resource imposes on society. The other is marginal extraction cost--the opportunity cost of resources employed in the extraction activity. Scarcity rent is the cost of "using up" a finite resource because benefits of the extracted resource are unavailable to future generations. Efficiency is achieved when the resource price--the benefit society is willing to pay for the resource today--is equal to the sum of marginal extraction cost and scarcity rent.

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.
