Lesson 3: Scarcity | Unit 2: Resources Page: 6 of 17

Topic: Free or Scarce? <=PAGE BACK | PAGE NEXT=>

We have limited resources. Limited resources can be free or scarce.
  • Scarce Resource. A resource is scarce if it can't produce all of the goods people want it to produce.
  • Scarce resource and scarcity are related. Scarcity is the society-wide condition in which resources are limited related to all wants and needs. Scarce resource is the condition that applies to a specific resource.
  • Free Resources. A resource is free if it can produce all of the goods people want it to produce and then some. We can have free resources, even though society faces the condition of scarcity.

SAVING-INVESTMENT MODEL

A variation of the Keynesian injections-leakages model that includes the two private sectors, the household sector and the business sector. This variation, more formally termed the two-sector injections-leakages model, captures the interaction between induced saving (and indirectly induced consumption expenditures) and autonomous investment expenditures. This model provides an alternative to the two-sector aggregate expenditures (Keynesian cross) analysis of the macroeconomy, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the saving line and the investment line. Two related variations are the three-sector injections-leakages model and the four-sector injections-leakages model.
