>>The best past experiment, in the Canadian town of Dauphin in the 1970s, was considered promising because it suggested the policy didn't discourage people from working much; only teenagers and new moms (two groups who might be better off not working anyway) reported working less. Typically, both of those groups are low-income, and therefore wouldn't be contributing that much to tax anyway. Its precisely the idea that taxpayers will decide not to work which is driving these studies.
