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.

This isn't me! What am I?

Ragnar Frisch and Jan Tinbergen were the 1st Nobel Prize winners in Economics in 1969.
"The creative is the place where no one else has ever been. the You have to leave the city of your comfort and go into wilderness of your intuition. What you'll discover will be wonderful. What you'll discover will be yourself."

-- Alan Alda, Actor
