X: The standard abbreviation for exports produced by the foreign sector and purchased by the domestic economy, especially when used in the study of macroeconomics. This abbreviation is most often seen in the aggregate expenditure equation, AE = C + I + G + (X - M), where C, I, G, and (X - M) represent expenditures by the four macroeconomic sectors, household, business, government, and foreign. The United States, for example, sells a lot of the stuff produced within our boundaries to other countries, including wheat, beef, cars, furniture, and, well, almost every variety of product you care to name.

VARIABLE INPUT An input whose quantity can be changed in the time period under consideration. The most common example of a variable input is labor. Variable inputs provide the means used by a firm to control short-run production. The alternative to variable input is fixed input. A fixed input, like capital, provides the capacity constraint in production. As larger quantities of a variable input, like labor, are added to a fixed input like capital, the variable input becomes less productive, which is the law of diminishing marginal returns.
