KEYNESIAN EQUILIBRIUM: The state of the macroeconomy in which aggregate expenditures are equal to aggregate output. This is illustrated using the income-expenditure model, or Keynesian cross, as the intersection of the aggregate expenditures line and the 45-degree line. The aggregate expenditures line is the summation of consumption expenditures, investment expenditures, government purchases, and net exports. The 45-degree line represents all combinations in which aggregate expenditures equal aggregate output. Keynesian equilibrium is also represented by the saving-investment, or injection-leakage, model as the intersection between the injection line (investment expenditures, government purchases, and exports) and the leakage line (saving, taxes, and imports).

MARGINAL PRODUCTIVITY THEORY A theory used to analyze the profit-maximizing quantity of inputs (that is, the services of factor of productions) purchased by a firm in the production of output. Marginal-productivity theory indicates that the demand for a factor of production is based on the marginal product of the factor. In particular, a firm is generally willing to pay a higher price for an input that is more productive and contributes more to output. The demand for an input is thus best termed a derived demand.
