Right away, the data clearly showed that cash helped people spend more on their basic needs. Those who received $1,000 monthly spent $67 more per month than the lower-paid group on food, $52 more on rent and $50 more on transportation. They also spent about 26 percent more financially supporting others, typically family members or children, suggesting that the beneficiaries of guaranteed income programs extend beyond the actual participants.
Some of the volunteers told the researchers that the money allowed them to stop living paycheck to paycheck and start imagining what they could do if they had more financial breathing room. Karina Dotson, OpenResearch’s research and insights manager, often heard participants talk about the cash giving them a “sense of self.” She said it “gave them head space to dream, to believe, to hope, to imagine a future they couldn’t imagine before.” Other research has found similar outcomes.
Those who received $1,000 monthly were 5 percent more likely to report having a budget, spending an average of 20 minutes more a month on finances than the group that received $50 monthly. The money also affected how much medical care people sought, how much they considered entrepreneurship or additional schooling and even the kinds of jobs they took. Those choices varied widely from person to person.
One of my favorite charities, GiveDirectly, researched the effects of large cash transfers on inflation in Kenya.
