HOW?: One of three basic questions of allocation (What? and For Whom? are the other two). Answering the "How?" question of allocation determines how society's limited resources will be combined in the production goods. Do we produce houses with wood or bricks? Do we make cars with automated robots or human labor?

MARKET SHARE: The fraction of an industry's total sales accounted for by a single business. In general, market share is a "first-guess" indicator of a firm's market control. If, for example, a company has a market share of 100 percent (that is, a monopoly), then you can rest assured it has a substantial amount of market control. A company with a 25 percent market share has less, but still notable, market control. In fact, when you get right down to the bottom line, the phrase "market share" is only worth mentioning for oligopolistic firms with a significant degree of market control. There really is no market control for a monopolistically competitive firm with a 0.00000001 percent market share.

FIXED INPUT

An input whose quantity cannot be changed in the time period under consideration. The relevant time period is usually termed the short run. The most common example of a fixed input is capital. The alternative to fixed input is variable input. A fixed input, such as capital, provides the "capacity" constraint for the short-run production of a firm. A variable input, such as labor, provides the means of changing short-run production. As larger quantities of a variable input are added to a fixed input, the variable input becomes less productive, which is the law of diminishing marginal returns.
