INJECTION LINE: A line used in the injection-leakage model representing the relation between non-consumption expenditures (that is, injections) and national income. The three injections are investment expenditures, government purchases, and exports. The foundation of the injection line is the investment line, which is then enhanced by adding government purchases and exports. The other part of the injection-leakage model is a line representing leakages. The intersection of the injection and leakage lines identifies equilibrium aggregate output, or Keynesian equilibrium.

AGGREGATE DEMAND CURVE: A graphical representation of the relation between aggregate expenditures on real production and the price level, holding all ceteris paribus aggregate demand determinants constant. The aggregate demand, or AD, curve is one side of the graphical presentation of the aggregate market. The other side is occupied by the aggregate supply curve (which is actually two curves, the long-run aggregate supply curve and the short-run aggregate supply curve). The negative slope of the aggregate demand curve captures the inverse relation between aggregate expenditures on real production and the price level. This negative slope is attributable to the interest-rate effect, real-balance effect, and net-export effect.

OLIGOPOLY AND MONOPOLISTIC COMPETITION Oligopoly and monopolistic competition have some similarities, but also have a few important differences. Both are examples of imperfect competition on the market structure continuum between ideals of perfect competition and monopoly. However, oligopoly contains a small number of large firms and monopolistic competition contains a large number of small firms. The dividing line between oligopoly and monopolistic competition can be blurred due to the number of firms in the industry.
