Answers to Price Controls Handout

1. Market for cheese:

a. Binding price floor: set above equilibrium price.  Price rises, quantity of cheese sold falls.  Surplus.

c. Farmers benefit.  Government loses.

2. Market for Frisbees:

a. $8, 6 million Frisbees

b. $10, 2 million Frisbees sold

c. Price ceiling of $9 is above the market equilibrium price of $8; therefore, we return to equilibrium because the new price ceiling is ineffective/non-binding.  6 million Frisbees will be sold at $8 each.

3. Market for labor and minimum wage:

a. Employment will decrease, wages of employed workers will increase.

Written responses to the questions below must be turned in on Friday, September 16th, 2010.
Responses must be written in complete sentences and must be typed, double-spaced, 12 point Times New Roman font with standard margins. For each response, you must support your answer with specific evidence from the book.

Foreword by Burton G. Malkiel

1. The study of economics has often been criticized for a variety of reasons. What are those reasons?

2. The influence of economics is present in many business, financial, and government communities. What are some institutions and agencies that rely on economics in some significant way?


3. Give one example of a politician (in the United States or abroad) who has failed to understand economics and as a result, failed to understand how to solve a problem society faces.

Chapter 1: The Power of Markets

4. What does it mean to “maximize your utility?”

5. What are some “barriers to entry” that make it so only seller can provide a good or service? Why are barriers to entry important?

6. What is meant by “price discrimination?” Why do you think airlines are able to price discriminate?

7. What does Wheelan mean when he says the market economy operates as an “amoral force?”

8. Besides prices, what is another way that firms can compete in order to outperform their competition?

9. According to Wheelan, what makes markets a good way to organize economic activity?

Chapter 2: Incentives Matter

10. What problem do communal resources present, as compared to privately owned resources?

11. Why do incentives matter? Use an example from the book as well as from your own life to explain your response.

12. The law of unintended consequences states that “actions of people – and especially of government – always have effects that are unanticipated or unintended” (The Concise Encyclopedia of Economics). While important to recognize, politicians often fail to understand its significance. Provide one example mentioned in the reading that illustrates this point.

13. “Capitalism can be a brutal, cruel process…But ‘creative destruction’ (Joseph Schumpeter) is a tremendous positive force. Competition means losers, which goes a long way to explain why we embrace it in theory and fight it bitterly in practice.” Explain this statement, and give an example.

Chapter 3: Government and the Economy

14. What positive and negative externalities are associated with cigarette smoking? Can you make the case that the positives outweigh the negatives?

15. What makes taxation a good solution the problem of negative externalities?

16. List all of the ways that government is essential in order for a market economy to operate successfully.

Answer to problem about illegal drugs:

1. Supply curve shifts because the US government is devoting billions of dollars each year to reduce the flow of drugs into the country.

2. Supply curve shifts to the left to reduce the amount of illegal drugs produced.

3. Price increases, quantity decreases.

4. Demand for illegal drugs is inelastic because drug users are addicted and therefore see the drugs as necessities.  Supply is also inelastic because it takes a considerable amount of time to produce more, so sellers cannot respond to a price change quickly.  Given this information, the graph should illustrate two mostly vertical lines.  When the supply shifts to the left, price increases dramatically, but quantity only falls slightly.  The large price increase, coupled with the addicted users, leads to an increase in drug-related crime as addicts resort to crime to pay for their habit.  Total revenue for sellers continues to increase, even with the reduction in supply, because of the inelastic demand for the product.

5. Drug-related crime increases because price has gone up so much, and addicts still need the drugs.

6. Rather than the supply curve shifting left, the demand curve would shift to the left instead as policymakers reduce the demand through drug education.  As a result, price would decrease, and quantity would decrease.  With a price decrease, sellers of illegal drugs would not make as much money and would lose total revenue.  This change might create an incentive to leave the drug market altogether.  There would also be a reduction in drug-related crime as a result of a price decrease.
