1、Production Possibilities,When faced with SCARCITY of resources,decisions have to be made about how to use those resources,Trade-offsOpportunity Costs,Trade-Offs,This is the decision making process that is occurring in your mind right now!Am I going to pay attention to what Mr.Hayward is saying,or am

2、 I going to daydream?Am I going to come to class or go buy a lottery ticket?Am I going to stay in school or go find a full time job?Each and every decision you make has a cost!Not necessarily a cost in dollar terms,but a cost in that you must give up something in order to get more of something else.

3、,Opportunity Cost,The“price you pay”for each decision you make is called the OPPORTUNITY COST.Opportunity cost is vital to the understanding of economics.“The amount of a product or service that must be forgone(given up)in order to obtain more of the next best alternative product or service”,The bes

4、t way to illustrate Trade-Offs and Opportunity Costs is to use a Production Possibilities Curve,The PPC shows the relationship between two goods:1.Capital Goods(Investment Goods)Goods that satisfy our wants INDIRECTLY and promote future growth or“happiness”Delayed gratification.2.Consumer GoodsGoods
