The Self-Sufficiency Project was a Canadian experiment in the 1990s that provided a "generous, time-limited earnings supplement available to single parents who had been on welfare for a least a year, and who subsequently left welfare and found full-time work."^[1]

The study found that individuals offered a SSP subsidy were four percent more likely to stay on welfare to receive the benefit, but once people qualified for the SSP supplement, 44% left welfare dependence and were employed full-time—defined as working at least 30 hours a week. The program was interesting since increases in employment boosted payroll and other taxes to a large enough extent that the subsidy paid for itself.

Later research suggested that the control group was on trend to catch-up with those who received the supplement in the long-run.^[2][3][4]
