GDP Isn’t Perfect • GDP does NOT measure • Nonmarket Activities • Underground Economy • Quality of Life After sifting all this information, Greenfield concludes that the total value of underground economic activity in the United States was $337 billion in 1990 (6.2 percent of GDP). Of this, about $268 billion is estimated to be from unreported legal-source income, and the rest from illegal activities. Such a percentage would put the U.S. underground economy slightly below the median estimate for the major industrial countries. -Invisible, Outlawed and Untaxed: America's Underground Economy
