Perfectly vertical.
Compared to the equilibrium price and quantity sold in a competitive market, a monopolist will charge a ______________ price and sell a ______________ quantity:
Higher; larger
Lower; larger
Higher; smaller
Lower; smaller
The monopolist has no supply curve because:
The quant ity supplied at any particular price depends on the monopolist's demand curve
The monopolist's marginal cost curve changes considerably over time.
The relationship between price and quantity depends on both marginal cost and average cost.
There is a single seller in the market.
