  4. Trade-Offs and Opportunity Costs • To determine what will be gained or lost in your personal life, a business, or in a economy, economist implement a production possibilities frontier (a diagram of goods and services , two at a time, that an economy can produce at full-strength). • Look at pg. 16 in your books at The Production Possibilities Frontier (PPF). • Some things to think about: • On the graph labeled “A” what could make the quantity of guns rise and the butter to stay the same? • On the graph labeled “B”, what does it mean when the caption reads, “When all resources are not fully used, a country cannot reach its potential.”? • What are some hypothetical possibilities on why the production of butter went down 200 units, but the gun manufacturer did not suffer any lack in production. • How does our nation’s drop-out rate affect the PPF?
