A) 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. 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 10 percent of the value of production in the United States.
