d. all resources are fully employed.
Thomas Edison once complained that he was not making a profit selling light bulbs
because his plants were operating 25 percent below capacity. He estimated that he could
increase output 25 percent with a 2 percent increase in the cost of production. He sold
the 25 percent on the foreign market at a price below what he called the “cost of
production.” We can deduce that Edison really meant
a. Marginal cost was below average cost but less than marginal revenue.
b. Average cost exceeded variable cost, which exceeded marginal revenue.
c. Variable cost exceeded fixed cost but was less than marginal revenue.
d. Marginal cost was above average cost but greater than marginal revenue.
The production possibilities frontier illustrates
a. the fundamental fact of scarcity.
b. the opportunity cost of acquiring more of one good.
c. maximum output utilizing all resources efficiently.
d. All of the above are correct.
