For Week 2 – Sept 24

Week 2:  Demand and Supply – The Foundation of Economics


This week we lay the the foundation for the whole study of economics.  We will learn how prices are determined in markets.  Sellers with an idea of the price they would like to get for what they are selling – a reserve price try to find a willing buyer.  Buyers come to the market with a notion of what they want and the max they are willing to pay for it.   Together these buyers and sellers negotiate their way to an equilibrium price.

We will look at the reasoning behind buyers and sellers behavior, how an equilibrium is arrived at and why prices change.
