About this unit

In this unit we explore markets, which is any interaction between buyers and sellers. We start by deriving the demand curve and describe the characteristics of demand. Next, we describe the characteristics of supply. Finally, we explore what happens when demand and supply interact, and what happens when market conditions change.
