Curly and Moe are considering living alone or being roommates and splitting the rent for the next twelve months. If they live alone, they each rent a one bedroom, one bath apartment for $500 per month, while if they are roommates, they can split a two bedroom, one bath apartment for $800 per month. The one difficulty they have is that Moe snores very loudly. Curly estimates the cost of poor sleep due to Moe's snoring at $150 per month. Moe could obtain a snore-eliminating device for $50 per month. The least costly solution to the externality present in this situation is for:

Moe to eliminate his snoring

Consider two restaurants located next door to each other: Quick Burger and The Sunshine Café. If Quick Burger opens a drive-through window, the increased traffic and noise will bother customers seated outside at The Sunshine Café.

Suppose Quick Burger has the legal right to operate a drive-through window, and Quick Burger and the Sunshine Café can negotiate with each other at no cost. Which of the following arrangements would lead to the socially optimal outcome?

The Sunshine Cafe pays Quick Burger $10,500 per month not to operate the drive-through window

Suppose that the EPA has proposed strict controls on the amount of sulfur that diesel fuel contains. These controls were designed to fully offset the cost of pollution generated by diesel fuel vehicles. The effect of the regulation is estimated to increase the equilibrium price of a gallon of diesel fuel by 10 cents. Assuming that the supply of diesel fuel has a positive slope and demand has a negative slope, the quantity of diesel fuel sold after imposition of the regulation will:

decrease

Two firms, Kegareta Inc. and Sucio Enterprises, have access to five production processes, each one of which has a different cost and gives off a different amount of pollution.

A village has five residents, each of whom has an accumulated savings of $50. Each villager can use the money to buy a government bond that pays 10 percent interest per year or to buy a year-old goat, send it onto the commons to graze, and sell it after one year. The price of the goat that the villager will get at the end of the year depends on the amount of weight it gains while grazing on the commons, which in turn depends on the number of goats sent onto the commons, as shown in the table below. Assume that if a villager is indifferent between buying a bond and buying a goat, the villager will buy a goat. What will be the total village income if each villager decides how to invest based on his or her individual self-interest?

Lunch in Jamie's dorm is an all-you-can-eat buffet, served from 11 a.m. until 1 p.m. By noon, the buffet is picked over, and by 12:30, there are very few popular items left. The garbage bins, though, are full of food. If the cafeteria changed its policy so that students had to pay for each item chosen, students would:

only select an item if its marginal benefit is greater than or equal to its price.

Suppose there are ten people playing cards in a room. One of them wants to smoke a cigar, nine of them dislike the smell of cigar smoke. The smoker values the privilege of smoking at $5, and each of the other nine people of the room would be willing to pay fifty cents for clean air in the room. The rules governing use of the room state that smoking is not allowed unless everyone agrees to allow smoking. If the rules governing the room instead stated that smoking is allowed unless everyone in the room agrees to prohibit it, then:

the cigar smoker will smoke and not have to pay the other occupants for the external cost.

Suppose you are an economic researcher, and you have access to detailed information about all of the firms in a given geographic area. You would conclude that the pollution reduction policy in that area is efficient if you observe that:

the marginal cost of reducing the externality is zero.

Suppose that a government agency is trying to decide between two pollution reduction policy options. Under the permit option, 100 pollution permits would be sold, each allowing emission of one unit of pollution. Firms would be forced to shut down if they produced any units of pollution for which they did not hold a permit. Under the pollution tax option, firms would be taxed $250 for each unit of pollution emitted. The regulated firms all currently pollute and face varying costs of pollution reduction, though all face increasing marginal costs of pollution reduction. Suppose the regulators chose the permit policy instead of the tax policy. What might explain that decision?

the permit policy allows regulators to achieve reduction goals without having detailed knowledge about firms' abatement costs
