VARIABLE INPUT: An input whose quantity can be changed in the time period under consideration. This should be immediately compared and contrasted with fixed input. The most common example of a variable input is labor. A variable input provides the extra inputs that a firm needs to expand short-run production. In contrast, 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. This is, by the way, the law of diminishing marginal returns.

- The MP curve as the graphical relation between marginal product values and variable input quantities.
- The connection between the law of diminishing marginal returns and the shapes of the total product, average product, and marginal product curves.
- The three stages of production characterized by the slopes of the total and marginal product curves.

GOVERNMENT PURCHASES Expenditures made by the government sector on final goods and services, or gross domestic product. Government purchases are used to buy the goods and services needed to operate the government (such as administrative salaries) and to provide public goods (including national defense, highway construction). These purchases are one of two major categories of government spending, the other is transfer payments. Government purchases are financed by a mix of taxes and borrowing and are categorized by the three levels of government: federal, state, and local governments. These are one of four expenditures on gross domestic product. The other three are consumption expenditures, investment expenditures, and net exports.
