A whole 1.3 hours a week or $490 per year at federal minimum wage. Essentially a rounding error. Also worth mentioning it doesn’t say what they were working before so this may simply be a reduction on overtime to take better care of other things such as family, health etc. there’s plenty of things other than finding a “better job” or “being an entrepreneur” that would fall into social or leisure but still reduce things like future healthcare, prison system expenses etc.
From the reason link:
The five researchers who published the paper tracked 1,000 people in Illinois and Texas over three years who were given $1,000 monthly gifts from a nonprofit that funded the study. The average household income for the study’s participants was about $29,000 in 2019, so the monthly payments amounted to about a 40 percent increase in their income. Relative to a control group of 2,000 people who received just $50 per month, the participants in the UBI group were less productive and no more likely to pursue better jobs or start businesses, the researchers found. They also reported “no significant effects on investments in human capital” due to the monthly payments. Participants receiving the $1,000 monthly payments saw their income fall by about $1,500 per year (excluding the UBI payments), due to a two percentage point decrease in labor market participation and the fact that participants worked about 1.3 hours less per week than the members of the control group.
Participants in the study generally did not use the extra time to seek new or better jobs—even though younger participants were slightly more likely to pursue additional education. There was no clear indication that the participants in the study were more likely to take the risk of starting a new business, although Vivalt points out that there was a significant uptick in “precursors” to entrepreneurialism. Instead, the largest increases were in categories that the researchers termed social and solo leisure activities.
