LONG-RUN MARGINAL COST: 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.

MONEY FUNCTIONS: Any item used as money in an economy performs automatically takes on four basic functions: (1) medium of exchange, (2) measure of value, (3) store of value, and (4) standard of deferred payment. While "buying and selling" means that money is THE medium of exchange, by far THE most important function of money, money also performs measure of value, store of value, and standard of deferred payment functions. Measure of value, also termed unit of account, means that prices are stated in terms of money. Store of value means that value, the satisfaction of wants and needs, can be stored over time using money. Standard of deferred payment means that future payments, such as paying off a car loan, are also in terms of the monetary unit.

AGGREGATE EXPENDITURES The total expenditures on gross domestic product undertaken in a given time period by the four sectors--household, business, government, and foreign. Expenditures made by each of these sectors are commonly termed consumption expenditures, investment expenditures, government purchases, and net exports. Aggregate expenditures (AE) are a cornerstone in the study of macroeconomics, playing critical roles in Keynesian economics, aggregate market analysis, and to a lesser degree, monetarism. In particular, aggregate expenditures are combined with the price level as aggregate demand.
