AGGREGATE EXPENDITURE LINE: A line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

OLIGOPOLY A market structure characterized by a small number of large firms that dominate the market, selling either identical or differentiated products, with significant barriers to entry into the industry. This is one of four basic market structures. The other three are perfect competition, monopoly, and monopolistic competition. Oligopoly dominates the modern economic landscape, accounting for about half of all output produced in the economy. Oligopolistic industries are as diverse as they are widespread, ranging from breakfast cereal to cars, from computers to aircraft, from television broadcasting to pharmaceuticals, from petroleum to detergent.
