of land and other natural resources that are

Perfectly Inelastic Supply
• Why?
–
No production costs associated with land
–
Economy has a finite supply of land
–
Variability in the usability of land affects a very
small fraction of the total amount of land

investment goods

Interest rates allocate the available supply of money to
those projects which are expected to result in the highest
levels of profit
