In this lesson, we studied the notions of wealth creation in markets - how both buyers and sellers can be made "better off" (increase their utility or profits) by participating in markets. We then addressed the concept that a market is a dynamic thing - it is constantly changing with time. Since we model a market by using two things: a demand curve and a supply curve - we are able to examine all changes in a market by movements of the supply and demand curves.
We looked at what happens to markets when supply and demand curves move. We then examined the root causes of movements of the supply and demand curves.
