or five years from now?
c. Studies also find that teenagers have a higher
price elasticity than do adults. Why might this be true?
12. You are the curator of a museum. The museum is running short of funds, so you decide to increase revenue. Should you increase or decrease the price of admission? Explain.
13. Pharmaceutical drugs have an inelastic demand, and computers have an elastic demand. Suppose that technological advance doubles the supply of both products (that is, the quantity supplied at each price is twice what it was).
a. What happens to the equilibrium price and quantity in each market?
b. Which product experiences a larger change in price?
c. Which product experiences a larger change in quantity?
d. What happens to total consumer spending on each product?
14. Several years ago, flooding along the Missouri and the Mississippi rivers destroyed thousands of acres of wheat.
a. Farmers whose crops were destroyed by the floods were much worse off, but farmers whose crops were not destroyed benefited from the floods. Why?
b. What information would you need about the market for wheat to assess whether farmers as a group were hurt or helped by the floods?
15. Explain why the following might be true: A drought around the world raises the total revenue that farmers receive from the sale of grain, but a drought only in Kansas reduces the total revenue that Kansas farmers receive.
1. Lovers of classical music persuade Congress to impose a price ceiling of $40 per concert ticket. As a result of this policy, do more or fewer
people attend classical music concerts?
2. The government has decided that the free-market price of cheese is too low.
a. Suppose the government imposes a binding price floor in the cheese market. Draw a supply-
and-demand diagram to show the
effect of this policy on the price of cheese and the quantity of cheese sold. Is there a shortage or surplus of cheese?
b. Farmers complain that the price floor has reduced their total revenue. Is this possible? Explain.
c. In response to farmers‘ complaints, the government agrees to purchase all the surplus cheese at the price floor. Compared to the basic price floor, who benefits from this new policy? Who loses?
3. A recent study found that the demand and supply
schedules for Frisbees are as follows:
Price per Quantity Quantity Frisbee Demanded Supplied
$11 1 million Frisbees 15 million Frisbees 10 2 12 9 4 9 8 6 6 7 8 3 6 10 1
a. What are the equilibrium price and quantity of Frisbees?
b. Frisbee manufacturers persuade the government that Frisbee production improves scientists‘ understanding of aerodynamics and thus is important for national security. A concerned Congress votes to impose a price floor $2 above the equilibrium price. What is the new market price? How many Frisbees are sold?
c. Irate college students march on Washington and demand a reduction in the price of Frisbees. An even more concerned Congress votes to repeal the price floor and impose a price ceiling $1 below the former price floor.
What is the new market price? How many Frisbees are sold?
4. Suppose the federal government requires beer drinkers to pay a $2 tax on each case of beer purchased. (In fact, both the federal and state governments impose beer taxes of some sort.) a. Draw a supply-and-demand diagram of the market for beer without the tax. Show the price paid by consumers, the price received by producers, and the quantity of beer sold. What is the difference between the price paid by consumers and the price received by producers?
b. Now draw a supply-and-demand diagram for the beer market with the tax. Show the price paid by consumers, the price received by producers, and the quantity of beer sold. What is the difference between the price paid by consumers and the price received by producers? Has the quantity of beer sold increased or decreased?
5. A senator wants to raise tax revenue and make workers better off. A staff member proposes raising the payroll tax paid by firms and using part of the extra revenue to reduce the payroll tax paid by workers. Would this accomplish the senator‘s goal? Explain.
6. If the government places a $500 tax on luxury cars, will the price paid by consumers rise by more than $500, less than $500, or exactly $500? Explain.
7. Congress and the president decide that the United States should reduce air pollution by reducing its use of gasoline. They impose a $0.50 tax for each gallon of gasoline sold. a. Should they impose this tax on producers or consumers? Explain carefully using a supply-and-demand diagram.
b. If the demand for gasoline were more elastic, would this tax be more effective or less effective in reducing the quantity of gasoline consumed? Explain with both words and a diagram.
c. Are consumers of gasoline helped or hurt by
this tax? Why?
d. Are workers in the oil industry helped or hurt by this tax? Why?
8. A case study in this chapter discusses the federal minimum-wage law.
a. Suppose the minimum wage is above the equilibrium wage in the market for unskilled labor. Using a supplyand- demand diagram of the market for unskilled labor, show the market wage, the number of workers who are employed, and the number of workers who are unemployed. Also show the total wage payments to unskilled workers.
b. Now suppose the secretary of labor proposes an increase in the minimum wage. What effect would this increase have on employment? Does the change in employment
depend on the elasticity of demand, the elasticity of supply, both elasticities, or neither?
c. What effect would this increase in the minimum wage have on unemployment? Does the change in unemployment depend on the elasticity of demand, the elasticity of supply, both elasticities, or neither?
d. If the demand for unskilled labor were inelastic, would the proposed increase in the minimum wage raise or lower total wage payments to unskilled workers? Would your answer change if the demand for unskilled labor were elastic?
9. The U.S. government administers two programs that affect the market for cigarettes. Media campaigns and labeling requirements are aimed at making the public aware of the dangers of cigarette smoking. At the same time, the Department of Agriculture maintains a price-support program for tobacco farmers, which raises the price of tobacco above the equilibrium price.
a. How do these two programs affect cigarette consumption? Use a graph of the cigarette market in your answer.
