According to the Rational Rule for Sellers, the manager of this company should choose to produce _____ of output and charge a price of _____.
How does marginal revenue compare to price for a seller with market power?
Beyond the first unit sold, marginal revenue is below price.
If a firm faces a downward-sloping demand curve:
P > MR
How is the result of the Rational Rule for Sellers different for companies with market power versus companies with no market power?
The price is higher for companies with market power
The demand curve for a monopoly is:
above the MR curve
If Penelope, a monopolist, is producing a quantity where MC < MR, then profit:
can be increased by increasing production
market power leads to
higher equilibrium price inefficiently smaller quantity larger economic profits businesses w market power can survive even with inefficiently high cost
If a monopolist is producing a quantity that generates MC = MR, then profit:
is maximized
order from highest to lowest market power
monopoly oligopoly monopolistic competition perfect competition

If Penelope, a monopolist, is producing a quantity where MC = P, then profit:
can be increase by decreasing production
If Penelope, a monopolist, is producing a quantity where MC > MR, then profit:
can be increased by decreasing production
If a monopolist produces a quantity that generates MC < MR, then profit:
can be increased by increasing output.

(Figure: Demand, Revenue, and Cost Curves for Thneeds) Use Figure: Demand, Revenue, and Cost Curves for Thneeds. Thneeds and Things is a monopolist in the thneed ("things we need") market. If the government wants to regulate Thneeds so that an efficient outcome is reached, it would impose a price ceiling of:
