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.

RESOURCE QUALITY, AGGREGATE SUPPLY DETERMINANT

One of three categories of aggregate supply determinants assumed constant when the short-run or long-run aggregate supply curves are constructed, and which shifts both aggregate supply curves when it changes. An increase in a resource quality causes an increase (rightward shift) of both aggregate supply curves. A decrease in a resource quality causes a decrease (leftward shift) of both aggregate supply curves. The other two categories of aggregate supply determinants are resource quantity and resource price. Specific determinants falling into this general category include education and technology. Anything affecting the quality of labor, capital, land, and entrepreneurship is also included.
