LRMC: The abbreviation for long-run marginal cost, which is the change in the long-run total cost of producing a good or service resulting from a change in the quantity of output produced. Like all marginals, long-run marginal cost is the increment in the corresponding total. What's most notable about long-run marginal cost, however, is that we are operating in the long run. Unlike the short run, in which at least one input is fixed, there are no fixed inputs in the long run. As such, there is only variable cost. This means that long-run marginal cost is the result of changes in the cost of all inputs.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
