Nevertheless, Gross Domestic Product (GDP) measures the market value of "all final products and services produced in that country within a certain period of time" (Gwartney, Stroup, Sobel and Macpherson, 2013, 131 pages). This is an incomplete calculation. This is because GDP is underestimated as "10% to 15% of total production" because the trade of goods and services hidden by specific individuals and companies is not included in GDP (Gwartney , 2013, p.

People engaged in underground activities are avoided, avoided or excluded from rules, rights, regulations and enforcement punishment regulations governing authorized distributors engaged in production and exchanges. Different kinds of underground activities are distinguished according to specific institutional rules that violate. We can identify four major underground economies.
