This video lesson introduces the concept of market failure and examines one type of market failure, a negative externality of production. If the producers of a good face lower costs than society as a whole, too much of the good will be produced and the market fails to achieve efficiency. In such a case, government may be needed to intervene and promote a more socially optimal level of output through the use of corrective taxes.
