Earlier this month, a cross-border team of North American economists published the results of a landmark study, probably the best and most careful yet done, of how low-income workers respond to an unconditional guaranteed income. Not so long ago this would have been a plus-sized news item in narcissistic Canada, for the lead author of the study is a rising economics star at the University of Toronto, Eva Vivalt. The economists, working through non-profit groups, recruited 3,000 people below a certain income cutoff in the suburbs of Dallas and Chicago. A thousand of these, chosen at random, were given a thousand dollars a month for three years. The rest were assigned to a control group that got just $50 a month, plus small extra amounts to encourage them to stay with the study and fill in questionnaires.
