UNDERGROUND ECONOMY: Illegal and unreported market transactions and productive activity that escape the watchful eyes of official record keepers.

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.
