Document Summary

Ecn 104 chapter 16 externalities march 30th. Externalities: an external cost is an uncompensated cost that an individual or firm imposes on others, an external benefit is a benefit that an individual or firm confers on others without receiving compensation. Yet most pollution is a side effect of activities that provide us with good things. Our air is polluted by power plants that generate the electricity that lights our cities, and our rivers are damaged by fertilizer runoff from farms that grow our food. Pollution is a side effect of useful activities, so the optimal quantity of pollution isn"t zero. The marginal social cost of pollution (msc) is the additional cost imposed on society as a whole by an additional unit of pollution: msc = mpc + mec. The marginal private cost of pollution (mpc) is the additional cost imposed on the polluter if the polluter creates another unit of pollution.

Question 1

An externality

		enhances market efficiency.
		is a private cost or benefit that results from the production or consumption of a good or service that is external to a market.
		is a benefit or cost that affects someone who is not directly involved in the production or consumption of a good or service.
		refers to production or consumption that occurs outdoors.

Question 2

Externalities can be produced by:

		the high price of goods and services
		individuals; firms
		market prices; market incomes
		oceans; streams

5 points

Question 3

When an external cost exists that is NOT taken into account in the production of a product,

		the level of output is too high, and the supply curve should shift to the left to account for the externality.
		the price of the product is too high, and production should be expanded to lower the price.
		the level of output is optimal, and there should be no change in the supply curve.
		the level of output is too low, and the supply curve should shift to the right to account for the externality.

Question 4

Which of the following is correct?

		MSC = MPC - MD
		MPC = MSC + MD
		MSC = MPC + MD
		MD = MSC + MPC

5 points

Question 5

If external costs (costs of cleaning up) are included and added to a firm's private costs, then

		the demand curve will shift to the left.
		the supply curve will shift to the right.
		the demand curve will shift to the right
		the supply curve will shift to the left.

5 points

Question 6

The Coase Theorem states that

		government intervention is always needed if externalities are present.
		assigning property rights is the only thing the government should do in a market economy.
		if transaction costs are low, private bargaining will result in an efficient solution to the problem of externalities.
		a free-market equilibrium is the best solution to address externalities.

5 points

Question 7

Buffalo in the United States almost became extinct while cattle, an animal that provides similar products, never have been close to extinction. The difference is due to

		the use of private property rights on cattle and common property rights on buffalo.
		the greater marginal value of a head of cattle relative to buffalo, leading to over-hunting of buffalo.
		cattle existing in Europe also while buffalo were specific to North America.
		the greater marginal value of a buffalo relative to a steer, leading to the overharvesting of buffalo.

Question 8

In theory, the Emissions Fee would

		cause firms to generate less pollution than their allowed limits.
		raise the production costs of all firms.
		cause firms to generate more pollution than their allowed limits.
		lower the production costs of all firms.

5 points

Question 9

A cap-and-trade policy

		has a set number of permits.
		allows polluters to trade permits.
		caps the total level of pollution allowed.
		all of the above.

Question 10

		market congestion.
		market losses.
		inefficient sales.
		low market prices.
