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.

PROPORTIONAL TAX

A tax in which the proportion of income paid in taxes is the same for all income levels. A proportional income tax exists if ever taxpayer pays exactly the same tax rate relative to income regardless of income level. A proportional tax is one of three alternations. The other two are progressive tax, in which the proportion of income paid in taxes is greater for higher income levels, and regressive tax, in which the proportion of income paid in taxes is smaller for higher income levels.

This isn't me! What am I?

In his older years, Andrew Carnegie seldom carried money because he was offended by its sight and touch.
"New ideas pass through three periods: - It can't be done. - It probably can be done, but it's not worth doing. - I knew it was a good idea all along!"
