Tax incidence

depends on the elasticities of supply and demand.

The market demand curve for a monopolist is typically

downward sloping.

An agreement between two duopolists to function as a monopolist usually breaks down because

each duopolist wants a larger share of the market to capture more profit.

Demand is said to have unit elasticity if the price elasticity of demand is

equal to 1.

A free-rider problem exists for any good that is not

excludable

If people can be prevented from using a certain good, then that good is called

excludable

A profit-maximizing firm in a monopolistically competitive market differs from a firm in a perfectly competitive market because the firm in the monopolistically competitive market

faces a downward-sloping demand curve for its product.

Each firm in a monopolistically competitive market

faces a downward-sloping demand curve.

Firm A produces and sells in a market that is characterized by highly differentiated consumer goods. Firm B produces and sells industrial products. Firm C produces and sells an agricultural commodity. Which firm is likely to spend the greatest portion of its total revenue on advertising?

have a negligible impact on the market price.

The general term for market structures that fall somewhere between monopoly and perfect competition is

imperfectly competitive markets.

A certain competitive firm sells its output for $20 per unit. The 50th unit of output that the firm produces has a marginal cost of $22. Production of the 50th unit of output does not necessarily

is a price taker, whereas a monopolist is a price maker.

For a firm to price discriminate,

it must have some market power.

marginal cost equals price, while a monopolist produces where price exceeds marginal cost.

If firms are competitive and profit maximizing, the price of a good equals the

marginal cost of production.

In which of the following product markets are we likely to observe the largest amount of advertising?

markets with highly differentiated products

Because public goods are

not excludable, people have an incentive to be free riders.

one buyer

A firm cannot price discriminate if it

operates in a competitive market.

Assume that your roommate is very messy. Suppose she gets a $25 benefit from being messy but imposes a $50 cost on you. The Coase theorem would suggest that an efficient solution would be for you to

pay your roommate at least $25 but no more than $50 to clean up after herself.

A good is excludable if

people can be prevented from using it.

The provision of public goods gives rise to

positive externalities, whereas the use of common resources gives rise to negative externalities.

The relationship between advertising and product differentiation is

positive; the more differentiated the product, the more a firm is likely to spend on advertising.

As the number of firms in an oligopoly increases, the

price approaches marginal cost, and the quantity approaches the socially efficient level.

The practice of selling the same goods to different customers at different prices, but with the same marginal cost, is known as

price discrimination.

Total revenue equals

price x quantity.

A textbook is a

private good and the knowledge that one gains from reading the book is a public good.

private goods.

A key characteristic of a competitive market is that

producers sell nearly identical products.

Refer to Figure 13-1. Suppose the production function shifts from TP1 to TP2. Such a shift in the total product curve is most likely due to an increase in the firm's

productivity.

Markets do not ensure that the air we breathe is clean because

property rights are not well established for clean air.

Markets fail to allocate resources efficiently when

property rights are not well established.

A production function is a relationship between inputs and

quantity of output.

the quantity of output to produce and the price at which it will sell its output.

Table 3-23: Assume that the farmer and the rancher can switch between producing pork and producing tomatoes at a constant rate. Refer to Table 3-23. Assume that the farmer and the rancher each has 24 labor hours available. If each person spends all his time producing the good in which he has a comparative advantage and trade takes place at a price of 1 pound of pork for 2 pounds of tomatoes, then

the rancher will gain from this trade, but the farmer will not.

Suppose that a firm produces electricity by burning coal. The production process creates a negative externality of air pollution. If the firm does not internalize the cost of the externality, it will produce where

the value of electricity to consumers equals the private cost of producing electricity.

The production decisions of perfectly competitive firms follow one of the Ten Principles of Economics, which states that rational people

think at the margin.

The nature of a firm's cost (fixed or variable) depends on the

time horizon under consideration.

Governments can grant private property rights over resources that were previously viewed as public, such as fish or elephants. Why would governments want to do so?

to prevent overuse

The amount of money that a firm receives from the sale of its output is called

total revenue.

From society's standpoint, cooperation among oligopolists is

undesirable, because it leads to output levels that are too low and prices that are too high.

Consumer surplus equals the

value to buyers minus the amount paid by buyers.

Analyzing the behavior of the firm enhances our understanding of

what decisions lie behind the market supply curve.

A firm charges a price that exceeds marginal cost

when the market is a monopoly or monopolistically competitive.

In the short run, a firm incurs fixed costs

whether it produces output or not.

​A rain barrel is a container that captures and stores rainwater for landscape and garden use during dry periods. Rain barrels provide an external benefit to the community through water conservation.If the government offers a per unit subsidy on rain barrels equal to the per-unit externality, then

​the after-subsidy equilibrium quantity of rain barrels will equal the socially optimal quantity of rain barrels.

The United States has imposed taxes on some imported goods that have been sold here by foreign countries at below their cost of production. These taxes

harm the United States as a whole, because they reduce consumer surplus by an amount that exceeds the gain in producer surplus and government revenue.
