Show all of your work. The exam ends at 10:50. 1. (a) (5pts) Draw a production possibilities frontier (PPF) for peanuts and chocolate. Now suppose that the working-age population in this society shrinks. Assume that labor is used to produce both goods. On your graph show how (if at all) the PPF would shift due to this decrease in population. (b) (5pts) Draw a PPF for shelter and entertainment. Now suppose that there is an invention that allows more shelter to be produced using the same amount of resources as before. On your graph show how (if at all) the PPF would shift due to this technological innovation. (c) (5pts) Draw a PPF for food and clothing. Now suppose that the best production techniques are not used. On your graph show how (if at all) the PPF would shift due to using inferior production techniques. 2.(20pts) Suppose that gasoline and tomatoes are both produced in perfectly competitive markets. Use supply and demand analysis to explain the following observation. “More gasoline and tomatoes are sold in the summer than in the winter, yet the price of gasoline is higher and the price of tomatoes is lower in the summer than in the winter.” In your explanation, refer to supply and demand diagrams for tomatoes and gasoline. 3. Suppose that cigarettes are produced in a perfectly competitive market. Consider the information in the February 4, 2004 Wall St Journal article below. Use this information to answer Questions (a)- (i) on this page and the next two pages. Quit-Smoking Proposal Calls for $2-a-Pack Tax Associated Press WASHINGTON -- Four former surgeons general unveiled a plan to reduce smoking that included a $2-a-pack tax they predicted would prompt at least five million smokers to quit. They also called for a nationwide counseling and support line for smokers trying to quit. More than $25 million would be dedicated for the toll-free, national "quitline". The 10-point plan endorsed by the former surgeons general and other health advocates seeks additional tobacco research, better doctor training and an extensive media campaign explaining the dangers of smoking. It also urges that the cigarette excise tax be raised to $2.39 from 39 cents, of which 50% of the proceeds, or $14 billion, would go toward paying for the various aspects of the plan. About 50 million Americans smoke, with many of them concentrated in poor neighborhoods where treatment isn't widely available. Health officials have estimated that smoking causes about 440,000 premature deaths a year and costs the nation $75 billion in direct health-care expenses. "It is the equivalent of another 9/11 World Trade Center, Pentagon and Pennsylvania disaster occurring about every two days," said Julius Richmond, surgeon general under President Carter. (a) (5pts) Consider the information in first paragraph of the article. Do the surgeons general believe that the demand curve for cigarettes is totally inelastic? Explain how you can tell. (b) (5pts) What does economic theory suggest are the determinants of the price elasticity of demand for cigarettes? (c) (5pts) Draw a supply and demand curve for cigarettes. Be sure to label your axes. On your graph, label the equilibrium price P1 and the equilibrium quantity Q1. Now consider the proposal by the surgeons general to increase the national excise tax on cigarettes by two dollars per pack. (d) (5pts) Explain exactly what would happen to the supply curve for cigarettes if this excise tax increase went into effect. Be as precise as possible in your explanation. (e) (2pts) On your graph from part (c), draw the supply curve you described in part (d). Label this new supply curve S2. Now consider the proposal by the surgeons general for an extensive media campaign explaining the dangers of smoking, and a nationwide counseling and support line for smokers trying to quit. (f) (5pts) Explain what would happen to the demand curve for cigarettes if this education and counseling campaign were implemented. (g) (2pts) On your graph from part (c) draw the demand curve you described in part (f). Label this new demand curve D2. (h) (2pts) On your graph from part (c), find the new equilibrium if the proposal by the surgeons general were implemented. Label the new equilibrium price P2 and the new equilibrium quantity Q2. (i) (3pts) If the proposal were implemented, would the price of cigarettes rise by two dollars? Explain your answer. (j) (6pts) Given the estimate in the article about the amount of tax revenue that would be generated by the extra two dollars of excise tax, how many cigarettes do the surgeons general estimate would be sold after their proposal is implemented? 4. (30pts) Suppose that you serve on a city council. In your city, the market for apartment rentals is perfectly competitive. A two bedroom apartment currently rents for $900 per month. A group of residents has asked the city council to impose rent control. This group wants the city to set a maximum legal limit of $700 per month on rent for a two-bedroom apartment. They suggest that this rent ceiling will help residents find affordable apartments. Your fellow city council members ask you to use economic theory to explain the likely effects of rent control. In your answer, you should refer to a supply and demand diagram for two-bedroom apartments. In your analysis, include an explanation of what would happen to consumer and producer surplus.
