Applying Supply and Demand

« Previous | Next »

Session Overview

You may not realize it, but every time you purchase something, you are participating in a market for that good. Some people supply it, and some people—you!—demand it. In this lecture, we will examine how to analyze supply and demand curves and the impact changes in market conditions and government policy can have on market equilibrium. Government intervention can impact gasoline prices. Image courtesy of Aaron Tyo-Dikerson on Flickr.

Keywords: Supply and demand; equilibrium; demand shift; supply shift; government interference.
