MARKET STRUCTURE CONTINUUM: A diagram illustrating alternative degrees of market control held by different types of market structures based on the number of firms in the market and the degree of competitiveness. As the number of competitors along the continuum ranges from one to many, the degree of market control ranges complete to none. At one end of the continuum, with many competitors on no market control, is perfect competition. At the other end, with one competitor and complete market control, is monopoly. Oligopoly and monopolistic competition comprise the interior of the continuum, with monopolistic competition having many competitors but limited market control and oligopoly having few competitors and greater market control. The continuum illustrates that clear-cut dividing lines really do not exist between the market structures, especially for monopolistic competition and oligopoly.

MARGINAL PROPENSITY TO INVEST

The change in business investment expenditures induced by a change in income or production (national income or gross domestic product). The marginal propensity to invest (abbreviated MPI) is another term for the slope of the investment line and is calculated as the change in investment divided by the change in income or production. The MPI plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part to the multiplier process. A related marginal measure is the marginal propensity to consume.
