OLIGOPOLY AND MONOPOLISTIC COMPETITION: Oligopoly and monopolistic competition have some similarities, but also have a few important differences. Both are examples of imperfect competition on the market structure continuum between ideals of perfect competition and monopoly. However, oligopoly contains a small number of large firms and monopolistic competition contains a large number of small firms. The dividing line between oligopoly and monopolistic competition can be blurred due to the number of firms in the industry.

Lesson 3: Scarcity | Unit 1: The Concept
|
Page: 1 of 17
|
- Scarcity is the pervasive condition that exists because society has unlimited wants and needs, but limited resources used for their satisfaction.
Meaning:- We can't have everything because resources are limited.
Unlimited wants and needs are half of the scarcity problem.- Unlimited wants and needs are what motivate us to take action, to produce goods, and to advance our well-being.
- We are motivated to do things that satisfy these wants and needs. Satisfaction is achieved when wants and needs are fulfilled.
- Scarcity results because wants and needs are unlimited. No one has ever been completely satisfied. We always want more.
Limited resources are the other half of our scarcity problem. - Resources are the stuff that we use to produce the goods that fulfill our wants and needs.
- Resources are the things that make satisfaction possible.
- Resources are limited. We have only so much 'stuff' than can be used to produce the goods that satisfy our wants and needs.

INFLATIONARY EXPECTATIONS, AGGREGATE EXPENDITURES DETERMINANT One of several specific aggregate expenditures determinants assumed constant when the aggregate expenditures line is constructed, and that shifts the aggregate expenditures line when it changes. An increase in inflationary expectations causes an increase (upward shift) of the aggregate expenditures line. A decrease in inflationary expectations causes a decrease (downward shift) of the aggregate expenditures line. Other notable aggregate expenditures determinants include interest rates, federal deficit, consumer confidence, and exchange rates.
