IMPLICIT OPPORTUNITY COST: An opportunity cost that does NOT involve a money payment or a market transaction. This should be contrasted with explicit cost that DOES involve a money payment or a market transaction. The common misconception among non-economists out there in the real world is that the term "cost" is synonymous with the term "payment," that is, all costs are explicit costs, to be a cost you have to give up some money. Well, I'm here to tell you that this isn't true. Cost is opportunity cost. It's the satisfaction NOT received from activities NOT pursued. It's the value of foregone production. And not all opportunity costs involve a money payment.

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. See also | market | market control | imperfect competition | oligopoly | monopolistic competition | concentration ratio |
