ECONOMIC COST: Another term for opportunity cost (the highest valued alternative foregone in the pursuit of an activity) that is used in the study of economics to indicate the fundamental role opportunity cost plays in economics. The value expressed in terms of satisfaction of the foregone activity is your opportunity cost. Because there are usually several alternatives that aren't pursued, opportunity cost is the highest-valued one. An opportunity cost is sometimes compensated with some form of payment, like a wage. However, the existence of an opportunity cost is independent of any actual cash outlay.

Methods of signalling include advertising, brand names, and warranties. A related method is screening.
