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.

FREE-RIDER PROBLEM A problem underlying the provision of public goods that occurs when a person consumes or benefits from a good without making payment. The free-rider problem is the primary reason that public goods are produced by governments. Because public goods are characterized by the inability to exclude nonpayers, once a public good is produced anyone, everyone, can consume without making payment, that is, get a "free ride." Voluntary payments like those occurring in markets will not provide enough revenue to pay production costs. The only way to finance public goods is to force free-riders, and everyone else, to pay through government taxes. The free-rider problem also applies to common-property goods.
