The perfectly competitive model does NOT assume:
that firms attempt to maximize their total revenue.
You own a deli. Which input of production is MOST likely fixed at your deli?
the dining room
Suppose a monopoly can separate its customers into two groups. If the monopoly practices price discrimination, it will charge the lower price to the group with:
the higher price elasticity of demand.
Perfect competition is characterized by:
the inability of any one firm to influence price.
Price discrimination can occur if:
the market structure is monopolistic competition.
Market structures are categorized by:
the number of firms and whether products are differentiated.
Network externalities exist when a good's value to the consumer rises as:
the number of people who use the good increases.
In economic analysis, the principle of marginal analysis refers to:
the result that the optimal quantity of an activity is that at which marginal benefit is equal to marginal cost.
An oligopoly is characterized as an industry in which:
there are few firms, each producing a differentiated or similar product.
A monopolistically competitive industry, such as corn snack chips, and a perfectly competitive industry, like wheat farming, are alike in that:
there are many firms in each industry.
Market equilibrium occurs when:
there is no incentive for prices to change in the market, quantity demanded equals quantity supplied, and the market clears.
Suppose the equilibrium price of good Y is $5 and the equilibrium quantity is 150 units. Supply in this market is upward sloping. If the price of good Y is $12:
there will be an excess supply of good Y.
If the several companies in the tobacco industry produce similar products but have very different marginal costs:
they are less likely to engage in tacit collusion than firms with similar costs.
(Figure: Pricing Strategy in Cable TV Market II) Use Figure: Pricing Strategy in Cable TV Market II. If CableNorth followed a high-price strategy one period but found that CableSouth followed a noncooperative low-price strategy, and CableNorth decided to lower prices for the next month, we would say that CableNorth is following a:Figure: Pricing Strategy in Cable TV Market II
tit-for-tat strategy.
If marginal costs of production are greater than marginal benefits of production:
too much of the good is being produced.
A firm's total output times the price at which it sells that output is _____ revenue.
total
The sum of fixed and variable costs is _____ cost.
total
Total revenue is a firm's:
total output times the price of that output.
The total cost curve shows how _____ cost depends on the quantity of _____.
total; output
(Figure: Monopoly Profits in Duopoly) Use Figure: Monopoly Profits in Duopoly. Suppose there are two firms in this industry. Each firm faces an identical demand curve, D1, and the market demand curve is D2. The figure illustrates how firms can reap monopoly profits, even in an industry with:Figure: Monopoly Profits in Duopoly
two firms.
(Figure: The Supply of Online Movie Rentals) Use Figure: The Supply of Online Movie Rentals. A decrease in the price of online movie rentals would result in a change illustrated by the move from:
u to v in panel D.
Cindy just graduated from college and started working at a large accounting firm. Although the firm will match her contributions to a retirement account, Cindy wants to wait several years before participating since there are so many things she needs to buy right now. What type of behavior does this represent?
unrealistic expectations about the future
In the long run, all costs are:
variable.
In the short run, the costs associated with variable inputs are _____, and the costs associated with _____ inputs are _____.
variable; fixed; fixed
Suppose Bob has a part-time business washing cars. He has washed nine cars on a given day; the marginal benefit of washing the tenth car is $20 and the marginal cost is $12. Bob should:
wash the tenth car.
The total product curve:
will become flatter as output increases if there are diminishing returns to the variable input.
Buford Bus Manufacturing installs a new assembly line. As a result, the output per worker increases. The marginal cost of output at Buford:
will decrease (the MC curve will shift down).
While eating pizza, you discover that the marginal benefit of eating one more slice is greater than the marginal cost of that slice. You conclude that:
you will be better off if you eat one more slice.
