Overview
In our lesson about consumer theory there are 2 major concepts we address: consumer surplus and consumer equilibrium. Consumer surplus is pretty easy to understand. It represents the difference between what we’re willing to pay for a product and the price we actually pay for the product. We also learn the 2 ways to calculate consumer surplus. The second major concept we discuss is consumer equilibrium, also referred to as utility maximization. This concept is a bit more complex, but ultimately comes down to finding the point where the utility per dollar spent on one item is equal to the utility per dollar spent on the other item.
