Scarcity exists. We have endless desires but limited resources. In Economics, we must choose. E. Napp

Trade-off • A trade-off occurs when we choose one course of action over another. • In Economics, we can never have everything we want or need. • We must make choices. • A woman spends ten dollars buying her lunch at a local restaurant. She cannot use the same ten dollars to buy a book. A trade-off has occurred. E. Napp

Sometimes a society is more concerned with economic growth than environmental quality. E. Napp

It’s All About Scarcity! • Scarcity exists. Our wants and desires are limitless but our natural resources are limited. • We can always want more than we have. As such, we are constantly choosing one course of action over another. • We cannot spend ten dollars on a movie ticket and the same ten dollars on a restaurant meal. E. Napp

E. Napp

Opportunity Cost • Whenever we make a decision, we receive one thing but give other things up. • If I chose to study tonight for the examination, I cannot go to the party or the movies or walk the dog. • The most desirable alternative given up for the decision is the opportunity cost. • Think of the opportunity cost as the best course of action of all those things you didn’t get. E. Napp

Scarcity and opportunity costs affect individuals, businesses, and governments. E. Napp

Guns or Butter • Government officials also must choose where to spend tax dollars. • When a government spends more money on the military, it must invariably spend less money on consumer goods like roads and schools. • Economists refer to government trade-offs as Guns or Butter. E. Napp

The Cost of War E. Napp

Thinking at the Margin • Sometimes a decision involves whether to add or subtract one additional unit of a resource. • After studying many hours, a student might ask herself: “Should I study one more hour?” • This question is a question at the margin. • Deciding whether to add or subtract one additional unit occurs at the margin. E. Napp

Should we study one more hour? That is thinking at the margin. E. Napp

Questions for Reflection • Provide examples of trade-offs. • Why do trade-offs exist? • What is the opportunity cost? • Provide an example of an opportunity cost? • What is thinking at the margin? • Provide an example of thinking at the margin. E. Napp
