Starting this week, 120 Germans will receive a form of universal basic income every month for three years.
The volunteers will get monthly payments of €1,200, or about $1,400, as part of a study testing a universal basic income.
The study will compare the experiences of the 120 volunteers with 1,380 people who do not receive the payments. About 140,000 people have helped fund the study through donations.
The concept of universal basic income has gained traction in recent years, and Finland tested a form of it in 2017.
Supporters say it would reduce inequality and improve well-being, while opponents argue it would be too expensive and discourage work.
