Homework 1.                            

  1. Explain how and why women’s and men’s roles in production changed through history (hunting and gathering, agriculture, colonial period, early industrialization, up to today).

  • b. List the expected benefits of a child.
  • c. If mom earns more than dad, who has lower opportunity cost of taking time off work to take care of a child? Explain the tradeoff involved in this decision.

4. The central assumption of economic theory is that humans are rational.  Rational people make choices by comparing costs and benefits of various alternatives and selecting the one with the highest net benefits. Give one example of a rational cost-benefit decision you have made recently. Describe your costs and benefits. Are you a rational person?

5. Near my house, there is a fast-food restaurant that sells egg muffins for $1.99 apiece.  At home, I have a fancy toaster-and-egg-steamer that can produce a virtually identical product.  You slice and butter an English muffin, stick it into the toaster slots; scramble an egg, pour it into the egg steamer, and add water to the steamer. Altogether, it takes about 15 minutes of preparation and cleaning. Producing an egg muffin at home costs only around $0.50.  Nonetheless, I often find myself stopping by McDonald’s instead.   Is it rational to buy the same product for more money at McDonald’s?  Explain why.

Graph the two PPFs.

8.  Some people believe that women have a comparative advantage in housework whereas men have a comparative advantage in work for pay. Are there biological, psychological, historical or cultural differences between genders that may explain this phenomenon?
