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.

INDUCED GOVERNMENT PURCHASES

Government purchases that depend on income or production (especially national income and gross domestic product). That is, changes in income induce changes in government purchases. Induced government purchases reflect the observation that the government sector (especially state and local governments) is inclined to use tax revenue, which increases with income, for purchases. They are measured by the marginal propensity for government purchases (MPG) and are reflected by the positive slope of government purchases line. The alternative to induced government purchases is autonomous government purchases, which do not depend on income.
