Summary
Highlights
The underground economy encompasses all trade and work conducted 'off the books,' outside government regulations and taxes. While it includes illegal activities like drug dealing, it also comprises common, less nefarious activities such as unlicensed hairdressing, street vending, and undeclared babysitting or domestic work.
Measuring the informal economy is challenging due to its hidden nature. Economists use indirect methods, such as comparing a country's total reported income with its expenditures, analyzing demand for cash (as many informal transactions are cash-based), and studying electricity consumption, which correlates with overall economic activity, to estimate its size.
The informal economy is massive, amounting to trillions of dollars globally. In developed countries, it's estimated to be 10-20% of GDP, while in developing countries, it can exceed one-third of economic output and employ half to three-quarters of non-farm workers. Organized crime alone is an 870-billion-dollar annual business.
Illegal trade within the informal economy, such as drug trafficking, counterfeiting, human trafficking, and environmental exploitation (e.g., timber and wildlife smuggling), generates billions. These markets are inherently dangerous due to a lack of regulation, as exemplified by the black market for human organs where sellers are exploited and buyers risk receiving diseased organs.
Some ethicists and economists argue for legalizing markets like organ sales, believing that regulation could improve safety and supply. However, this raises ethical concerns, such as the potential for poor individuals to be coerced into selling their organs, as seen in Iran where organ sales are legal.
For workers, the informal economy often means a lack of safety nets, poor working conditions, and increased poverty, particularly affecting women and migrant laborers. For governments, a large informal economy hinders accurate economic data collection, potentially leading to misguided policies and a reduction in tax revenue.
Despite its drawbacks, the underground economy can provide employment and income when formal jobs are scarce. During the US financial crisis, its size doubled, offering a temporary buffer for individuals and the broader economy. However, its growth can create a negative cycle, with reduced tax revenue leading to cuts in social services or increased taxes, pushing more people into informal work.
