A profit-maximising monopolist will choose a level of output at where:

The inefficiency of a deadweight loss stems from the fact that:

Patent and copyright laws are major sources of government created monopolies.

The main constraint facing the ability of a natural monopolist to price its product is:

Graph 15-2 This graph reflects the cost and revenue structure for a monopoly firm.Use the graph to answer the following question(s) . -Refer to Graph 15-2.The number of consumers who did not buy the good despite a willingness-to-pay greater than marginal cost is given by:

Total economic loss due to monopoly pricing is equal to:

Total economic loss due to monopoly pricing is equal to the loss to producer surplus minus the loss in consumer surplus.

Monopolies are inefficient because at the profit maximising quantity there will still be consumers whose willingness-to-pay is higher than the product's marginal cost.

If a monopolist faces a downward-sloping market demand curve, its:

A monopoly firm has an upward-sloping supply curve.
