a. How does the demand curve faced by a purely monopolistic seller differ from that confronting a purely competitive firm? b. Why does it differ? Of what significance is the difference? c. Complete the following statement.
The demand curve faced by a purely monopolistic seller is - downward sloping, whereas that facing the purely competitive firm is perfectly elastic.

The cashew industry is perfectly competitive and until now each of the identical firms in the industry have been earning zero economic profits while selling q1 units of output each (for a combined industry-wide total of Q1 units) at a market equilibrium price of P1 per unit. An unexpected increase in the demand for cashews raises the market equilibrium price to P2, which creates a situation in which P2 exceeds MC at q1 units of output.

Monopoly yields neither productive nor ________ efficiency.
allocative
________ efficiency means that resources are distributed among firms and industries to yield a mix of goods and services that is most wanted by society.
allocative
Competitive market economies generate ______.
allocative efficiency productive efficiency
Average fixed cost equals total fixed cost divided by the ______.

Because a monopoly is a price maker and prices its products in the elastic portion of the demand curve, its output is less than that required to achieve minimum average total cost. In addition, the monopoly's price will exceed its marginal cost at this level of output. Monopoly therefore creates
an efficiency loss.
