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 COST AND MARGINAL PRODUCT: Because variable cost is largely associated with the cost of employing a variable input in the short run, it's possible to identify a connection between the marginal cost curve and the marginal product curve. In particular, the quantity of output in which marginal cost is at a minimum, is the same quantity of output produced by the variable input when the marginal product of the variable input is at a maximum. In addition, over the range of production in which the variable input experiences increasing marginal returns and marginal product increases, the marginal cost curve declines. And over the range of production in which the variable input experiences decreasing marginal returns brought on by the law of diminishing marginal returns and marginal product increases, the marginal cost curve is rising. See also | marginal cost | marginal product | law of diminishing marginal returns | variable input | variable cost | fixed input | fixed cost | marginal cost curve | marginal product curve |

LABOR FORCE The total number of people in an economy, society, or country willing and able to exert mental and/or physical efforts in productive activities. The labor force is a more technical term for the labor resource or labor supply. It includes both employed workers and unemployed workers. An official variation of this term is civilian labor force. While labor force may or may not include military personnel, the civilian labor force explicitly excludes the military. Labor and labor resources are the theoretical terms that economists like to banter about. Labor force and civilian labor force are the terms of choice for government policy makers, data-crunchers, and others who need precise labor resource numbers.

"I learned about the strength you can get from a close family life. I learned to keep going, even in bad times. I learned not to despair, even when my world was falling apart. I learned that there are no free lunches. And I learned the value of hard work. " -- Lee Iacocca
