Document Summary

Short run average cost curve originates from production not market structure: curve the same for monopoly as perfect competition. Demand curve monopolies face is the original demand curve (of a particular product: total quantity consumers would like to purchase at a given price. Monopolies face a negatively sloped demand curve (unlike a perfectly competitive firm) Monopolists selling all units for the same price. Average revenue for all products sold at the same price. Demand curve is also the monopolist"s average revenue curve. Revenue resulting from the sale of one more unit of a product. A firm must reduce price on all units in order to sell one more unit: marginal revenue is equal to price minus revenue lost. Monopolist"s marginal revenue is less than the price at which it sells its output: marginal revenue curve is below its demand curve. Marginal revenue is always less than price for a monopolist.

A.total cost.
B.average total cost.
C.average variable cost.
D.average fixed cost.

A.greater than marginal cost.
B.less than marginal cost.
C.less than average variable cost.
D.greater than average total cost.

3. Monopolistic competition is an industry characterized by:

A.a product with many close substitutes.
B.a horizontal demand curve.
C.a small number of firms.
D.barriers to entry and exit.

4. If a perfectly competitive firm increases production from 10 units to 11 units, and the market price is $20 per unit, total revenue for 10 units is:

A.$10.
B.$20
C.$200.
D.$210.

A.horizontal, the same as that facing a perfectly competitive firm.
B.downward sloping, the same as that facing a perfectly competitive firm.
C.upward sloping, the same as that facing a perfectly competitive firm.
D.downward sloping, unlike the horizontal demand curve facing a perfectly competitive firm.

A.$1.
B.$9.
C.$19.
D.$29.

A.unregulated monopolies.
B.natural monopolies.
C.restricted-input monopolies.
D.sunk-cost monopolies.

8.If a perfectly competitive firm is producing a quantity that generates P > MC, then profit:

A.is maximized.
B.can be increased by increasing the price.
C.can be increased by decreasing the price.
D.can be increased by increasing production.

1. The principle that a firm should produce up to the point where the marginal revenue (MR) from the sale of an extra unit of output is equal to the marginal cost (MC) of producing the extra unit applies: ( I put A)

to both perfectly competitive firms and monopolies

only to monopolies

only to perfectly competitive firms

only to firms that can employ discriminatory pricing strategies

2. If a monopolist or a perfectly competitive firm is producing at a break-even point, then: ( I put II, IV)
i. average revenue is equal to average variable cost
ii. average revenue is equal to the o average total cost
iii. total revenue is equal to total variable cost
iv. total revenue is equal to the total cost

iii

I and iii

ii and iv

3. What do economies of scale, the exclusive ownership of essential raw materials used in the production process, and patents have in common? (I put A)

they are all barriers to entry

they all help explain why a monopolists demand and marginal revenue curves are identical

they must all be present before a monopolist may practice price discrimination

they all help explain why a firm's short-run average total cost curve is U-shaped
