His girlfriends?
Is there an opportunity cost to not doing homework?
Trade-off: giving up one thing to have something else

5. Section C: From Resources to Products.
Production
Resources
Factors of Production

Labor
Capital
Entrepreneurship
Production: The creation of any good or service
Resources: necessary for production.
NR: things in their natural state
L: human effort applied to NR to produce goods and services
C: the tools used by labor, can be raw material if made into other forms (lumber), Money only if used to by factories and other tools.
E: organization that brings about production, owner who organizes other factors, takes risk.

10. Crusoe’s Possibilities

11. Can Crusoe produce outside the PPF?
What does it mean if he is producing inside the PPF?
How could he move the PPF outward?

12. Point A: Working at LESS THAN maximum efficiency.
Opportunity cost does NOT have to be paid because to achieve more grain you do not necessarily have to give up more wine. You just need to be more efficient.

13. Points ON the curve: Maximum Efficiency
Because you are maximally efficient along the curve, it is NOT possible to move to another point along the curve without an opportunity cost being paid.

14. Point B: Moving beyond the curve.
Only possible if the curve is EXPANDED.
How do you move out the curve?
Improve the Quality and Quantity of your factors of production (FOP)
Examples: Better tools, technology, education, population growth, etc.
