Assume that the medical screening industry is perfectly competitive. Consider a typical
firm that is making short-run losses. Suppose the medical screening industry runs an
effective advertising campaign which convinces a large number of people that yearly
CT scans are critical for good health. How will this affect a typical firm that remains in
the industry?
A) The firm’s supply curve shifts right and its marginal revenue curve shifts upward as
the market price rises and ultimately the firm starts making profits.
B) The firm’s marginal revenue curve and average cost curve shift upward in response
to the increase in market price and advertising expenditure. The firm increases output
until it starts breaking even.
C) The marginal revenue curve shifts upward, the firm’s output increases along its
marginal cost curve, it expands production and eventually starts making profits.
D) The marginal revenue curve shifts upward, the firm’s output increases along its
marginal cost curve, it expands production until it breaks even.
Comparative advantage means
A) the ability to produce more of a product with the same amount of resources than any
other producer.
B) the ability to produce a good or service at a lower opportunity cost than any other
producer.
C) the ability to produce a good or service at a higher opportunity cost than any other
