© 2015 Pearson Education, Inc. 6 Tesla Can Trade Off Sedans for SUVs To produce 20 more SUVs (e.g. moving from A to B), Tesla must produce 20 fewer sedans. • The 20 fewer sedans is the opportunity cost of producing 20 more SUVs. Opportunity cost: The highest-valued alternative that must be given up to engage in an activity. Tesla’s production possibilities frontier Figure 2.1

© 2015 Pearson Education, Inc. 7 Increasing Marginal Opportunity Costs On the previous slide, opportunity costs were constant. But opportunity costs are often increasing. Why? Some resources are better suited to one task than another. The first resources to “switch” are the one best suited to switching. The more resources already devoted to an activity, the smaller the payoff to devoting additional resources to that activity. Increasing marginal opportunity costs Figure 2.2

Shifts in the production possibilities frontier represent economic growth. Economic growth: the ability of the economy to increase the production of goods and services. Figure 2.3a Economic growth

What would the production possibilities curve for the exam grades look like? A straight line, like the PPF for sedans and SUVs or A bowed-outward curve, like the PPF for tanks and automobiles? Why? The first hour spent studying Economics is much more valuable than the last hour
