Document Summary

A market is any arrangement that enables buyers and sellers to exchange information an do business with each other. In this course we will be examining a competitive market, this is a market that has many buyers and sellers and in which no single buyer has influence over the price of goods or services. Producers offer items for sale only if the price is high enough to cover the opportunity cost. In response to change of opportunity costs" customers go seeking cheaper alternatives. We must understand the relationship between price and opportunity cost. In everyday life when we talk about price, we are referring to the money price the amount of dollars (or yen or pesos) that must be given up in exchange for a good or service. As we well know the opportunity cost of something is the highest-valued alternative forgone (not taken).
