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.

DECISION LAG The time lag that it takes government leaders and policy makers to determine the appropriate government action needed to address an economic problem. The decision lag arises because it takes time for policy makers to chose among the array of possible policy actions, each with assorted consequences that appeal differently to different political constituencies. This "inside lag" is one of four policy lags associated with monetary and fiscal policy. The other two "inside lags" are recognition lag and implementation lag, and one "outside lag" is implementation lag. All four policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy.
