Econ Test 3 MC 26-50
Suppose that a monopoly firm produces tables and can sell 10 tables per month at a price of $400 per table. In order to increase sales by one table per month, the monopolist must lower the price of its tables by $30 to $370 per table. The marginal revenue of the eleventh table is:
$70
If the sellers of labor in a competitive market decided to unionize, ceteris paribus, then:
wages would rise and employment would fall
A gap in the marginal revenue curve results from:
a kinked demand curve
The soft drink market is dominated by Coke, Pepsi, and very few other firms. The firms often start price wars. The market can best be classified as:

the amount of output that is produced

the most valuable opportunity you give up when you do your homework
The only market structure in which there is significant interdependence among firms with regard to their pricing and output decisions is:
monopoly
Which market structure is characterized by a few interdependent firms?
oligopoly
When the MPP of labor is zero, ceteris paribus:
No further increases in output can be achieved by using additional units of labor
Compared with the profit-maximizing choice of a natural monopolist, output regulation will result in:
A higher level of output and a lower price
Which of the following rules will always be satisfied when any firm (i.e. perfectly competitive or monopoly) has maximized profits?
MR=MC
Oligopolistsic firms will maximize total profits for all of the firms in the market at the rate of output where:
MR=MC for the market
The collapse of AT&T's natural monopoly in long distance telephone service was caused by:
Satellite technology which made it easier and less expensive for new companies to provide long distance- service
According to the text, what type of market failure provides the best case for government regulation?
market power
At very high wage rates, it is likely that an individual's labor-supply curve:
bends backward
The demand for labor is downward sloping because of:
diminishing returns to labor
The supply curve for a monopolist:
does not exist
If a firm can raise market price by reducing its output, then:
it faces a downward-sloping demand curve
Ceteris paribus, if immigration to the United States increases the number of workers:
the labor-supply curve will shift to the right and the equilibrium wage rate will fall.
To be successful in changing wage rates and employment conditions, labor unions need to have control over only
their own members
As long as additional workers are attracted into the labor force by higher wages, the market labor supply curve is:
upward-sloping
The quantity of labor demanded can change without shifting labor demand curve when there is a change in:
wage rate
