If a firm wanted to know whether the demand for its product was elastic, unit elastic, or
inelastic, then the firm could
A) survey competitors and ask them what they think demand elasticity is for the
product.
B) talk to its customers.
C) change price a little bit and observe what happens to total revenue.
D) not do anything as there is no way to find an elasticity value.
Arnold Harberger was the first economist to estimate the loss of economic efficiency
due to market power. Since Harberger’s findings were published, other researchers have
studied this same issue. How do the results of these researchers compare to Harberger’s
results?
A) The other researchers reached conclusions similar to Harberger’s; namely, the loss of
economic efficiency due to market power is about 10 percent of the value of production
in the United States.
B) The other researchers reached conclusions different from Harberger’s; namely, they
found that the loss of economic efficiency due to market power is only about 1 percent
of the value of production in the United States, much less than Harberger’s estimate.
C) The other researchers reached conclusions different from Harberger’s; namely, the
loss of economic efficiency due to market power is about 10 percent of the value of
production in the United States, significantly greater than Harberger’s estimate.
D) The other researchers reached conclusions similar to Harberger’s; namely, the loss of
economic efficiency due to market power is about 1 percent of the value of production
in the United States.
