Lesson 3 Overview


In the previous lesson, we described and defined the demand curve, which relates prices and quantities on the consumption side of the market. In this lesson, we will learn about supply curves, which define the relationship between price and quantity on the producing side of the market.

What will we learn?

By the end of this lesson, you should be able to:

  • describe the differences between fixed, variable, average, and marginal costs;
  • understand the difference between "accounting" and "economic" profits;
  • describe risk-free returns and risk premiums;
  • define what is meant by "long-run" and "short-run," and what the difference between them is;
  • draw a supply and demand diagram, and identify the equilibrium point;
  • list and describe the assumptions of perfectly competitive markets.
