Eco 201 Name_______________________________ Test 2 15 April 2011 Please write answers in ink. You may use a pencil to draw your graphs. Good luck. Part I. 20 points each 1. Explain why price controls may actually end up making consumers worse off in areas that have experienced natural disasters such as hurricanes. High prices act as a signal to suppliers to increase the supply of goods and services in devastated areas. The resulting increase in supply then leads, eventually, to lower prices for these highly demanded goods/services. Without the initial increase in prices though, there would be no incentive for suppliers to increase supply and hence shortages occur and prices will not fall. 2. a. Rent controls are typically implemented as a means of helping low-income families afford housing. In general, is this a good way to help poor families? Explain why or why not. No, in general rent controls create shortages which make it hard for poor families to even find suitable housing. With rent controls also come high search costs—these search costs can be especially costly for people that landlords think are not 'ideal renters' (unfortunately many minorities or low-income households fall into this category). In short, most of the time rent controls typically end up making poor families worse off. Here’s a paragraph from the article on rent control in New York City: Yet the well-to-do reap a disproportionate share of rent regulation's rewards, at least by some calculations. A report by New York's Citizens Budget Commission, a nonpartisan watchdog group, calculated that in 1987, the subsidy from rent regulation averaged $345 monthly for tenant households with annual incomes above $75,000, and only $176 for households with incomes between $10,000 and $19,000. In some poor neighborhoods, there isn't any real subsidy, because incomes limit market rents. The citizens group concluded: "The poor get the least benefits from regulation and many may get no protection." Laurie P Cohen, “Home Free: Some Rich and Famous Of New York City Bask In Shelter of Rent Law,” Wall Street Journal, 21 March 1994 p. A1. Typically, groups that lose from rent controls are minorities and low-income persons, because landlords are more likely to rely on non-price rationing (e.g., renting only to affluent Caucasians) or side payments (e.g., key money) to allocate scarce rental housing. “Favored” racial or ethnic groups generally benefit from rent controls, as do the bureaucrats who enforce them. Rent controls reduce the available amount of housing, which will raise the prices of uncontrolled sources (such as single-family dwellings). If the controls apply to newly-constructed rental units, they will tend to reduce the value of vacant land, because fewer rental units will be built.b. Do shortages caused by rent controls tend to be larger in the short-run or the long-run? Use a supply and demand diagram to help illustrate your answer. In the long run under rent control, because landlords do not have incentives to maintain their properties, the supply of apartments at the control price declines. This exacerbates the shortage. Historically, some cities have seen the decline in apartments accelerate faster than would be predicted by normal wear and tear, as landlords set fire to their properties to collect the insurance money. See Steven N. S. Cheung, Roofs or Stars: The Stated Intents and Actual Effects of a Rents Ordinance, Economic Inquiry, vol. 13, No. 1, March 1975, pp. 1-21.Part II. 30 points each. 1. Using a supply and demand diagram as a reference, discuss the effects of a price ceiling on gasoline. Your answer should address at least four of the five effects we expect from ceilings. The price ceiling (1) causes a shortage, (2) wasteful lines that increase the costs to buyers, without any resulting gains to sellers, (3) losses in consumer and producer surplus. And (4) a misallocation of resources, since those with the highest willingness to pay may not get the gasoline.2. The accompanying diagram shows the effects of a tariff. Initially, the price is P0, domestic firms produce Q0 units, and Q1 - Q0 units are imported from foreign firms. When the tariff is imposed, the price increases to P0 + t. Complete the table below, by indicating the areas that represent consumer surplus, producer surplus, government revenue, social gains, and deadweight losses. Explain why deadweight losses result from a tariff. Before Tariff After Tariff Consumer Surplus A + B + C + D + E + F A + B Producer Surplus G C + D Tax Revenue E Social Gain A + B + C + D + E + F + G A + B + C + G Deadweight Loss D + FThe area D represents the resource waste associated with too much domestic production. Under an unregulated price system the additional resources to increase domestic production could not be bid away from alternative uses. Under the tariff the price signal is distorted, meaning the protected industry is able to bid these resources away from more socially more productive uses. Area F represents the deadweight loss from too little consumption. American households would like to purchase more imports, but the tariff prices many households out of the market. American households as a group are clearly worse off from this protectionist
