ENTRY BARRIERS: Institutional, government, technological, or economic restrictions on the entry of firms into a market or industry. The four primary barriers to entry are: resource ownership, patents and copyrights, government restrictions, and start-up costs. Barriers to entry are a key reason for market control and the inefficiency that this generates. In particular, monopoly, oligopoly, monopsony, and oligopsony often owe their market control to assorted barriers to entry. By way of contrast, perfect competition, monopolistic competition, and monopsonistic competition have few if any barriers to entry and thus little or no market control.

BALANCED-BUDGET MULTIPLIER

A measure of the change in aggregate production caused by equal changes in government purchases and taxes. The balanced-budget multiplier is equal to one, meaning that the multiplier effect of a change in taxes offsets all but the initial production triggered by the change in government purchases. This multiplier is the combination of the expenditures multiplier, which measures the change in aggregate production caused by changes in an autonomous aggregate expenditure, and the tax multiplier which measures the change in aggregate production caused by changes in taxes.
