Practice Problems

Note: The final exam will consist of 35-40 multiple choice questions and approximately 14 short answer questions.

1. You have been assigned the task of estimating the social trip cost at a traffic volume of 1,600 vehicles per lane per hour for a one-mile section of an urban freeway between two exits. You have traffic data for the relevant stretch of highway for the last year. Outline a strategy for computing the social trip cost. What information would you collect and how would you use it?

2. Consider a city that has both a congestion problem (it does not have a congestion tax) and an auto pollution problem (drivers do not pay for the pollution they generate).

a. Draw the private-trip-cost curve and the social-trip-cost curve.

b. Label the optimum volume V* and the equilibrium volume V0.

c. Suppose the city builds a light-rail transit system and subsidizes light-rail fares. Depict graphically a situation in which the subsidized light-rail system generates an auto volume of V*.

d. Does the fact that the light-rail system generates the optimum auto volume mean that it is an efficient policy?

3. Suppose the demand for driving in a month for a driver is given by MPB = 10 – 0.1Q.

Private costs are constant at $3, and social costs are constant at $3.70.

a. How many miles will this person drive in a month?

b. What is the inefficiency associated with this amount of driving?

c. What is the efficient vehicle miles traveled tax to correct for this inefficiency?

4. Explain why improving safety features in automobiles is not an efficient policy to address the accident externality associated with driving.

5. The price elasticity of demand for public transit equals -0.33. Consider a city with an initial fair for public transit of $1.50 and an initial ridership of 120,000. Suppose the city cuts its transit fare to zero. What is the total ridership after they reduce the fare to $1.00?

7. Political candidates often claim that they are “tough on crime” advocating harsher sentences, more police officers, etc.

a. Using the general crime cost/benefit graph, explain how whether being tough on crime is a net cost or a net benefit to society.

b. Will an increase in marginal prevention costs increase or decrease the efficient level of crime? Explain.

8. Critically appraise the following: “The social cost of armed robbery is about six times the social cost of burglary. According to the principle of marginal deterrence, the length of the prison term for armed robbery should be six times the length of the prison term for burglary.”

9. a.) How and why has the number of people imprisoned changed over the last 30 years?

b.)What are the 4 functions of prisons?

c.) Explains why most economists would that the number of people in prison is greater than the efficient level?

Critically appraise this statement: “Studies have shown that higher levels of incarceration has reduced violent crimes by approximately 20%. Clearly society is better off as a result of these higher levels of incarceration.”

10. List the pros and cons associated with legalization of marijuana.

11. Given our discussion of the market for illegal drugs, should policy, which is intended to reduce usage be more supply or demand oriented? Explain why using a basic market diagram to illustrate your answer.

12. If a drug is legalized, under what condition would the price of that drug increase? Under what condition would the price of that drug decrease?

13. The following represents the estimated results from a hedonic equation:

Y = 200,000 + 4,500*X1 + 300*X2 – 2,500*X3 (+-) B4*X4

Where:

Y is the market price of a home

X1 is the number of bathrooms

X2 is the size of the lot in square footage

X3 is the age of the home

X4 is distance to the major employment center

a. Explain the meaning of the coefficient on X1, the number of bathrooms.

b. What do you expect for the value of the coefficient on X4?

c. Suppose Y were given as the natural log of the market price of a home. How would you interpret the coefficient on X4.

d. Name two other variables that might be relevant to include as explanatory variables in this equation.

14. Explain why the average quality of housing is higher in the Western U.S. (California or Oregon) compared to in the Midwest U.S. (Ohio or Michigan). Illustrate your answer using a MC/MB graph.

15. What policy alternatives do policymakers have when it comes to how to address abandoned housing? Why can abandoned housing not be addressed in the same way other negative externalities are addressed.

16. If policymakers have a set budget equal to $1,000,000 to devote to the demolition of abandoned homes, what should they consider in deciding which neighborhoods/homes to target?

17. What are the major issues associated with public housing? What is the major issue associated with subsidies for private housing? Why do most economists prefer housing vouchers over the alternatives in order to improve housing affordability for the poor?

18. Explain why most economists believe that the home mortgage interest deduction is not an effective policy when it comes to its intended goal of increasing homeownership? What are the economic costs associated with the mortgage interest deduction?

19. Consider the effects of rent control in two cities, each of which imposes rent control with a maximum price of $400, compared to the equilibrium price of $500. In Elastic City, the price elasticity of supply of housing is 5.0. In Inelastic City, the supply elasticity is 0.4.

a. Which city will experience a larger reduction in the quantity supplied of housing?

b. Which city will experience a larger deadweight loss from rent control?

20. The following table reflects the total benefits of money (in thousands) spent on healthcare, crime, or education.

Healthcare Crime Education

Amount Spent ($) Benefits Benefits Benefits

1 4 6 10

2 7 11 15

3 10 15 18

4 12 18 20

5 14 21 21

6 16 23 22

7 17 24 22

8 18 25 22

9 19 26 22

10 19 26 22

a. If you, as a policymaker, have $10,000 to spend, how much should you spend on each policy? What are the total and net benefits?

b. Even if you had no limit on what you could spend, what is the maximum amount you would want to spend in total?
