Nationwide PRWOA meant that states were given some latitude on setting work requirements and providing work incentives.
Finally, researchers grapple with the problem of specifying the effects of waivers that the federal government granted to the states before the inception of the PRWOA.

CalWORKs(t) = California's welfare reform program under PRWOA which began in January 1998, at month t.

Presently, many states, including California, allow working participants to keep a larger portion of their benefits as their earnings increase than was the case before the inception of the PRWOA.
In part, concerns about long-term welfare dependency provided the primary reason for the recent and dramatic provisions under the federal PRWOA.
Under PRWOA, states also are allowed to exempt 20 percent of their caseload from the 60-month federal time limit.
