A study of an Iranian cash transfer program that covered over 70 million people, and paid out the equivalent of $16,390 per family in its first year, found that “the program did not affect labor supply in any appreciable way.”

The program began in 2011, depositing monthly cash deposits into individual accounts at 28% of the median per capita household income. The payments were a response to the loss of energy subsidies. In fact, the study found positive effects on the labor supply of women and self-employed men.
