AP Macroeconomics PPC Questions & Answers: Opportunity Cost & Shifts Review

📚 Quick Study Guide

• 🧭 Production Possibilities Curve (PPC): A graph that shows the maximum possible output combinations of two goods or services an economy can achieve when all resources are fully and efficiently employed.
• 💰 Opportunity Cost: The value of the next best alternative that must be given up when making a choice. It's what you forgo to get something else.
• ⬆️ PPC Shifts:
  • Rightward Shift: Economic growth, increased resources, or technological advancements. 🚀
  • Leftward Shift: Economic contraction, decreased resources, or disasters. 📉
• ⚖️ Constant Opportunity Cost: Resources are easily adaptable between the production of two goods; PPC is a straight line.
• 📈 Increasing Opportunity Cost: As you produce more of one good, the opportunity cost of producing the next unit increases; PPC is bowed outwards. This is more realistic.
• 💡 Efficiency: Points on the PPC represent efficient use of resources. Points inside the PPC are inefficient, and points outside are unattainable with current resources.
• 🧮 Calculating Opportunity Cost: If moving from point A (10 cars, 20 trucks) to point B (15 cars, 15 trucks), the opportunity cost of 5 more cars is 5 fewer trucks.
