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.

FOUR-SECTOR INJECTIONS-LEAKAGES MODEL A variation of the Keynesian injections-leakages model that adds the foreign sector to the three domestic sectors--the household sector, the business sector, and the government sector. This variation adds the foreign to the three domestic sectors (household, business, and government) in the three-sector model and provides an alternative to the four-sector aggregate expenditures (Keynesian cross). It provides the complete Keynesian representation of the macroeconomy, including the export-import interaction between the domestic economy and the foreign sector. Equilibrium is identified as the intersection between the S + T + M line and the I + G + X line. Two related variations are the two-sector injections-leakages model and the three-sector injections-leakages model.
