P = MC.

Assume that society places a higher value on the last unit of X produced than the value of the resources used to produce that unit. With no spillovers, this information means that

price is greater than marginal cost.

The MR = MC rule can be restated for a purely competitive seller as P = MC because

each additional unit of output adds exactly its price to total revenue

A purely competitive seller should produce (rather than shut down) in the short run

if total revenue exceeds total cost or if total cost exceeds total revenue by some amount less than total fixed cost.

Suppose that an industry's long-run supply curve is downsloping. This suggests that

it is a decreasing-cost industry.

travel agencies

A purely competitive firm's short-run supply curve is

upsloping and equal to the portion of the marginal cost curve that lies above the average variable cost curve.

For a pure nondiscriminating monopolist, marginal revenue is less than price because

when a monopolist lowers price to sell more output, the lower price applies to all units sold.

In the short run, a purely competitive firm that seeks to maximize profit will produce

where total revenue exceeds total cost by the maximum amount.

Suppose that a pure monopolist can sell 5 units of output at $4 per unit and 6 units at $3.90 per unit. The monopolist will produce and sell the sixth unit if its marginal cost is

Pure monopoly refers to

a single firm producing a product for which there are no close substitutes.

Economists would describe the U.S. automobile industry as

an oligopoly.

Which of the following is a characteristic of pure monopoly?

barriers to entry

For a purely competitive firm, total revenue

has all of these characteristics.

The supply curve for a monopolist is

nonexistent

If the long-run supply curve of a purely competitive industry slopes upward, this implies that the prices of relevant resources

rise as the industry expands.

GRAPH QUESTION: In the accompanying diagram, the quantitative difference between areas A and C for reducing the price from P1 to P2 measures

marginal revenue

For a pure monopolist, the relationship between total revenue and marginal revenue is such that

marginal revenue is positive when total revenue is increasing, but marginal revenue becomes negative when total revenue is decreasing.

In the long run, a pure monopolist will maximize profits by producing that output at which marginal cost is equal to

marginal revenue.

To maximize profit, a pure monopolist must

maximize the difference between total revenue and total cost.

Assume for a competitive firm that MC = AVC at $12, MC = ATC at $20, and MC = MR at $16. This firm will

minimize its losses by producing in the short run.

The practice of price discrimination is associated with pure monopoly because

GRAPH QUESTION: Refer to the diagram for a pure monopolist. If the monopolist is unregulated, it will maximize profits by charging

price P3 and producing output Q3

Comparing a pure monopoly and a purely competitive firm with identical costs, we would find in long-run equilibrium that the pure monopolist's

price and average total cost would be higher, but output would be lower.

When a purely competitive firm is in long-run equilibrium,

price equals marginal cost.

With respect to the pure monopolist's demand curve, it can be said that

price exceeds marginal revenue at all outputs greater than 1.

Resources are efficiently allocated when production occurs where

price is equal to marginal cost.

In the short run, a purely competitive seller will shut down if

price is less than average variable cost at all outputs.

Because the monopolist's demand curve is downsloping,

price must be lowered to sell more output.

(Last Word) Oil wells and seasonal resorts will often shut down temporarily because

prices for their output temporarily fall below their average variable costs of production.

Output Total Cost 0 $50 1 90 2 120 3 140 4 170 5 210 6 260 7 330 The accompanying table gives cost data for a firm that is selling in a purely competitive market. If product price is $45, the firm will

produce 5 units and realize a $15 economic profit.

Total Product Average Fixed Cost Average Variable Cost Average Total Cost Marginal Cost 1 $100.00 $17.00 $117.00 $17 2 50.00 16.00 66.00 15 3 33.33 15.00 48.33 13 4 25.00 14.25 39.25 12 5 20.00 14.00 34.00 13 6 16.67 14.00 30.67 14 7 14.29 15.71 30.00 26 8 12.50 17.50 30.00 30 9 11.11 19.44 30.55 35 10 10.00 21.60 31.60 41 11 9.09 24.00 33.09 48 12 8.33 26.67 35.00 56 The accompanying table gives cost data for a firm that is selling in a purely competitive market. If the market price for the firm's product is $28, the competitive firm will

produce 7 units at a loss of $14.00.

Other things equal, a price-discriminating monopolist will

produce a larger output than a nondiscriminating monopolist.

GRAPH QUESTION: Refer to the diagram for a natural monopolist. If a regulatory commission set a maximum price of P2, the monopolist would

produce output Q3 and realize a normal profit

The Ajax Manufacturing Company is selling in a purely competitive market. Its output is 100 units, which sell at $4 each. At this level of output, total cost is $600, total fixed cost is $100, and marginal cost is $4. The firm should

produce zero units of output.

GRAPH QUESTION: Refer to the diagram. If this somehow was a costless product (that is, the total cost of any level of output was zero), the firm would maximize profits by

producing Q2 units and charging a price of P2.

The vertical distance between the horizontal axis and any point on a nondiscriminating monopolist's demand curve measures

product price and average revenue.

On a per-unit basis, economic profit can be determined as the difference between

product price and average total cost

In which of the following industry structures is the entry of new firms the most difficult?

pure monopoly

In which one of the following market models is X-inefficiency most likely to be the greatest?

pure monopoly

GRAPH QUESTION: Line (2) in the diagram reflects a situation where resource prices

remain constant as industry output expands.

Which of the following is not a possible source of natural monopoly?

rent-seeking behavior

If the price of product Y is $25 and its marginal cost is $18

resources are being underallocated to Y.

GRAPH QUESTION: At output level Q1, in this diagram,

resources are underallocated to this product and productive efficiency is not realized.

Chart Question: At P4 in the accompanying diagram, this firm will

shut down in the short run

If at the MC = MR output, AVC exceeds price,

some firms should shut down in the short run

(Last Word) Fixed costs for a firm are analogous to

starting out in a hole that represents economic losses if the firm produces nothing

In answering the question, assume a graph in which dollars are measured on the vertical axis and output on the horizontal axis. For a purely competitive firm, total revenue graphs as

straight, upsloping line.

GRAPH QUESTION: Refer to the diagram for a pure monopolist. If a regulatory commission sets the price to achieve the socially optimal allocation of resources, it will have to

subsidize the monopolist or the monopolist will go bankrupt in the long run.

The short-run supply curve for a purely competitive industry can be found by

summing horizontally the segments of the MC curves lying above the AVC curve for all firms.

When LCD televisions first came on the market, they sold for at least $1,000, and some for much more. Now many units can be purchased for under $400. These facts imply that

the LCD television industry is a decreasing-cost industry.

Chart Question: Refer to the diagram for a purely competitive producer. The firm's short-run supply curve is

the bcd segment and above on the MC curve.

In answering the question, assume a graph in which dollars are measured on the vertical axis and output on the horizontal axis. For a purely competitive firm,

the demand and marginal revenue curves will coincide.

(Last Word) Temporary shutdowns of firms are most widespread when

the economy experiences recession.

GRAPH QUESTION: The diagram portrays

the equilibrium position of a competitive firm in the long run.

If a regulatory commission imposes upon a nondiscriminating natural monopoly a price that is equal to marginal cost and below average total cost at the resulting output, then

the firm must be subsidized or it will go bankrupt

If a pure monopolist can price discriminate by separating buyers into two or more groups,

the firm will face multiple marginal revenue curves.

If a purely competitive firm is producing where price exceeds marginal cost, then

the firm will fail to maximize profit and resources will be underallocated to the product.

The lowest point on a purely competitive firm's short-run supply curve corresponds to

the minimum point on its AVC curve.

Suppose an increase in product demand occurs in a decreasing-cost industry. As a result

the new long-run equilibrium price will be lower than the original long-run equilibrium price.

If a nondiscriminating pure monopolist decides to sell one more unit of output, the marginal revenue associated with that unit will be

the price at which that unit is sold less the price reductions that apply to all other units of output.

Creative destruction is

the process by which new firms and new products replace existing dominant firms and products.

The term productive efficiency refers to

the production of a good at the lowest average total cost

The term allocative efficiency refers to

the production of the product mix most desired by consumers.

(Consider This) Children are charged less than adults for admission to professional baseball games but are charged the same prices as adults at the concession stands. This pricing system occurs because

the seller can prevent children from buying game tickets for adults but cannot prevent children from buying concession items for adults.

Assume a purely competitive firm is maximizing profit at some output at which long-run average total cost is at a minimum. Then

there is no tendency for the firm's industry to expand or contract.

In a purely competitive industry,

there may be economic profits in the short run but not in the long run.

Chart Question: Curve (4) in the diagram is a purely competitive firm's

total cost curve

Chart question: Curve (1) in the diagram is a purely competitive firm's

total economic profit curve.

A firm reaches a break-even point (normal profit position) where

total revenue and total cost are equal.

Chart Question: Curve (3) in the diagram is a purely competitive firm's

total revenue curve.

A competitive firm will maximize profits at that output at which

total revenue exceeds total cost by the greatest amount.

Suppose a pure monopolist is charging a price of $12 and the associated marginal revenue is $9. We thus know that

total revenue is increasing.

Chart Question: Refer to the diagram, which pertains to a purely competitive firm. Curve A represents

total revenue only.

An important economic problem associated with pure monopoly is that, at the profit-maximizing outputs, resources are

underallocated because price exceeds marginal cost.

A nondiscriminating profit-maximizing monopolist

will never produce in the output range where demand is inelastic.

A pure monopolist's short-run profit-maximizing or loss-minimizing position is such that price

will vertically intersect demand where MR = MC

Creative destruction is least beneficial to

workers in the "destroyed" industries.

Total Product Average Fixed Cost Average Variable Cost Average Total Cost Marginal Cost 1 $100.00 $17.00 $117.00 $17 2 50.00 16.00 66.00 15 3 33.33 15.00 48.33 13 4 25.00 14.25 39.25 12 5 20.00 14.00 34.00 13 6 16.67 14.00 30.67 14 7 14.29 15.71 30.00 26 8 12.50 17.50 30.00 30 9 11.11 19.44 30.55 35 10 10.00 21.60 31.60 41 11 9.09 24.00 33.09 48 12 8.33 26.67 35.00 56 The accompanying table gives cost data for a firm that is selling in a purely competitive market. If the market price for the firm's product is $12, the competitive firm should produce

zero units at a loss of $100.

The diagram indicates that the marginal revenue of the sixth unit of output is

−$1.
