Markets are all around us and can be incredibly complex. In this module, the discussion moves toward introducing an important tool, supply and demand, for understanding how markets work.

The Demand Curve Lecture (1 video)(~3:30)

This lesson introduces the demand curve in more detail. 

The Supply Curve (1 videos)(~3:00)

These lesson introduces the supply curve in more detail. 

Equilibrium Price (1 videos)(~4:50)

These lesson introduces the idea of equilibrium price in more detail. 


Now that we have some idea of what markets are, we can see how important prices are for guiding buyers and sellers. We see how buyers and sellers (who have somewhat different objectives) find common ground. An equilibrium price emerges out of this interaction among buyers and sellers, which supply and demand help us understand in a deeper way.
