Source: MDRC calculations from Ohio unimployment insurance(UI) earnings records and AFDC records.
Notes: Estimates are regression-adjusted using ordinary laest squares, controlling for pre-random assignment characteristics of sample members. Rounding may cause slight discrepancies in calculating sums and differences. Because quarter 1, the quarter of random assignment, may contain some earrnings and AFDC payments from the period prior to random assignment, it is excluded from follow-up measures. "Percentage difference" equals 100 times "difference" divided by "control group." A two-tailed t-test was applied to differences between outcomes for the program and control groups. Statistical significance levels are indicated as: * = 10 percent; ** = 5 percent.; *** = 1 percent.
