UNDERGROUND ECONOMY: Illegal and unreported market transactions and productive activity that escape the watchful eyes of official record keepers. By most estimates, a substantial amount of productive activity takes place in the underground economy for the United States. Of course, these are only estimates because such activity, by definition, goes unreported. Were activity in the underground economy added to official activity in the "overground" economy, then gross domestic product could be boosted by as much as 25% to 50%, or more.

A theory used to analyze the profit-maximizing quantity of inputs (that is, the services of factor of productions) purchased by a firm in the production of output. Marginal-productivity theory indicates that the demand for a factor of production is based on the marginal product of the factor. In particular, a firm is generally willing to pay a higher price for an input that is more productive and contributes more to output. The demand for an input is thus best termed a derived demand.
