Suppose a company increases production from a point where marginal cost equals average total cost to a point where marginal revenue and marginal cost are equal. Is it a good idea for the company to do this? Why?
Yes (even though the previous level of output had minimized the average total cost, there was still profit to be earned by producing additional units.)
The act of buying a commodity in one market at a lower price and selling it in another market at a higher price is known as:
arbitrage.
A profit-maximizing firm will continue to expand output:
as long as the revenues from the production and sale of an additional unit exceeds the marginal cost of the unit.
The market price for wallets is $20. Your technology is such that at your most efficient production point, the average total cost of producing a wallet is $2.50. Your manager runs into your office and shouts, "Boss!!! Average costs are rising!! Average costs are rising!!" To make a profit-maximizing decision, you should:
ask the manager about the marginal cost.
A perfectly competitive firm's supply curve follows the upward-sloping segment of its marginal cost curve above the:
average variable cost curve.
Suppose a monopolist and a perfectly competitive firm have the same cost curves. The monopolistic firm would:
charge a lower price than the perfectly competitive firm.
If, at the point where MR = MC, the firm incurs losses, in the short run the firm should:
continue at its current output if P > AVC.
A firm's demand for labor depends on, in part, the demand for the firm's product. To summarize this idea, economists say that the demand for labor is:
derived demand.
The neighborhood ice cream shop finds that when it charges $3 per ice cream cone, its total revenues are $90,000. It has total variable costs of $30,000 and total fixed costs of $40,000. From this we can infer the:
economic profits are $20,000.
The entry of new firms into a monopolistic competitive industry will shift the:
existing firm's demand curve to the left.
In a competitive labor market a firm will continue to employ workers for as long as an additional worker's marginal revenue product is below the wage rate. - T/F
false
A union may negotiate limits on workload in order to increase the demand for labor and raise workers' salaries. This practice is known as:
featherbedding
Which of the following is true about long-run equilibrium in a monopolistically competitive market?
firms earn zero economic profit because price equals long-run average cost, but the equilibrium is not allocatively efficient because price exceeds the marginal cost of the last unit produced
If all firms in a monopolistic competitive industry have demand and cost curves like those shown in Exhibit 10-3, we would expect that in the long run:
firms in the industry earn zero economic profits.
Assume the short-run average total cost for a perfectly competitive industry increases as the output of the industry expands. In the long run, the industry supply curve will:
have a positive slope.
Compared to a perfectly competitive firm with the same cost structure, a monopoly firm will charge a:
higher price and sell more.
A merger between firms that compete in the same market is called a:
horizontal merger.
The monopolist's demand curve is:
identical to the market demand curve.
Under both perfect competition and monopoly, a firm:
is a price maker.
In the short run, a firm should shut down its operation if:
its losses are greater than TFC at the MR=MC Point
In a constant cost industry:
long run supply curve will be perfectly elastic
A perfectly competitive firm maximizes profits or minimizes losses in the short-run by producing at the output level at which:
marginal revenue equals marginal cost.
At the point where the marginal revenue equals zero for a monopolist facing a straight-line demand curve, total revenue is:
maximum.
The Sherman Antitrust Act of 1890 is the federal antitrust law that prohibits:
monopolization and conspiracies to restrain trade.
When oligopolists take into account their competitors' behavior, this situation is called:
mutual interdependence.
One reason the supply of carpenters is greater than the supply of physicians is because: ,
of differences in human capital.
Mutual interdependence applies to actions of:
oligopolists.
Under a rule of reason approach, an act is illegal:
only if it is shown to result in an anticompetitive outcome.
In order to obtain a conviction for price fixing under the Sherman Antitrust Act, the government needs to prove:
only that an attempt to fix prices was made.
Because a competitive firm is a price taker, it faces a demand curve that is:
perfectly elastic.
The practice of firms temporarily reducing prices in order to eliminate competition is called:
predatory pricing.
When the price of a good is a constant, the marginal revenue per unit of output is the same as:
price.
If a firm decreases output when MR < MC, then:
profit will increase
An exclusive contract:
requires a buyer not to purchase any requirements from the competitor of a specified supplier.
Suppose a previously competitive labor market turns into a monopsony. The labor supply curve faced by the new monopsonist is:
the market supply curve of labor
A monopoly is:
the only seller of a good for which there are no good substitutes in a market with high barriers to entry.
Perfect competition and monopolistic competition are similar because under both market structures,
there are zero economic profits in the long run.
Firms that place their assets in the custody of a board of trustees is called a(n):
trust. (or trust. combination. cartel. *all of these)
A manufacturer will sell its product only to retailers who agree to buy its brand. This is an example of:

zero pure economic profits.
