Assume an EPA official observes the following situation in a small town on the banks of a river. The town depends heavily on fish for its food and is heavily dependent on coal for its power. A coal factory on the banks of the river empties pollutants into the river, causing health problems among the residents and the fish to develop toxic residues in their livers and other organs. Which of the following solutions should the EPA choose to mitigate this negative externality problem (at least in the short run)? I. levy taxes on the coal factory's production of pollutants II. levy taxes on the consumers' consumption of fish III. create a market for tradable allowances IV. subsidize firms that produce clean fish

Every summer, Matt travels by air to see his grandmother. Matt's maximum willingness to pay for an airline ticket is $260, but the airline requires a minimum of only $100 to fly him. Normally, Matt pays the airline the going market price of $250 per ticket. If the government places a $50 tax on each ticket, raising ticket prices to $270 and causing Matt not to go, what is the deadweight loss created by this tax?
$160

Why might the benefits of monopolistic competition outweigh the inefficiencies?
If we had perfect competition instead of monopolistic competition, we would not have all the varietyand innovation that we have today.
The iconic blue-and-white Chinese porcelain sold to people all over the world (particularly between thefourteenth and the sixteenth centuries) was so successful, entrepreneurs in Persia, Netherlands, Syria, Iberia,Mexico, and many other areas attempted to copy it. The actual process for creating such high-quality ceramicswas kept secret, but in 1708 a German alchemist finally found a way to replicate the ancient art. What do youexpect happened to the price of porcelain after 1708, and why?
It should have fallen because of the increased competition.

Mobile homes are housing units installed on a permanent foundation owned by a landlord. Although a resident owns the home, she rents the foundation from the landlord. In theory, owners of mobile homes can transfer their home to a different foundation if the rent becomes too steep, but uninstalling, transporting, and reinstalling the mobile home is usually prohibitively expensive. This "lock-in" effect encourages state legislatures to create rent controls for mobile home foundations. Which statement is a plausible, unintended consequence of these laws?
There are few new mobile home foundations constructed.

Suppose there is a decrease in the labor costs for picking bananas at the same timethat there is an increase in the population. What will this do to the equilibrium price andquantity of bananas?

You've been hired as a management consultant to four different companies in competitive industries. They'reeach trying to figure out if they should produce a little more output or a little less output to maximize theirprofits. The firms all have typical marginal cost curves: They rise as the firm produces more. Your staff did allthe hard work for you of figuring out the price of each firm's output and the marginal cost of producing onemore unit of output at their current level of output. WaffleCo, maker of generic-brand frozen waffles: price = $4 per box; marginal cost = $2 per boxRio Blanco, producer of copper: price = $32 per ounce; marginal cost = $45 per ounceGoDaddy.com, domain name registry: price = $5 per Web site; marginal cost = $2 per Web siteLuke's Lawn Service: price = $80 per month; marginal cost = $120 per monthWhich firms should produce more, which should produce less, and which are producing just the right amount?
WaffleCo and GoDaddy.com are producing too little and Rio Blanco and Luke's Lawn Service areproducing too much.
