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.

SLOPE, NET EXPORTS LINE

The negative slope of the net exports line is based on the marginal propensity to import (MPM). Because net exports are exports minus imports, the induced change in imports causes an opposite change in net exports. As such, the slope of the net exports line is negative, less than zero (but greater than negative one). The slope of the net exports line affects the slope of the aggregate expenditures line and thus also affects the magnitude of the multiplier process.
