Separate from the Congressional action, some states are making it harder to qualify for the first few months of benefits, which are covered by taxes on employers. Florida, where the jobless rate is 8.7 percent, has cut the number of weeks it will pay and changed its application procedures, with more than half of all applicants now being denied.

The federal extension of jobless benefits has been a contentious issue in Washington. Republicans worry that it prolongs joblessness and say it has not kept the unemployment rate down, while Democrats argue that those out of work have few alternatives and that the checks are one of the most effective forms of stimulus, since most of it is spent immediately.

After the most recent compromise reached in February, another renewal seems unlikely.

The expiration of benefits is one factor contributing to what many economists refer to as a “fiscal cliff,” or a drag on the economy at the end of this year when tax cuts and recession-related spending measures will all come to an end unless Congress acts. The Congressional Budget Office warned last week that the combination could contribute to another recession next year.

Candace Falkner, 50, got her last unemployment check in mid-May, when extended benefits were curtailed in eight states. Since then she has applied for food stamps and begun a commission-only, door-to-door sales job. Since losing her job two years ago, Ms. Falkner said, she has earned a master’s degree in psychology and applied for work at numerous social service agencies as well as places like Walmart, but no offers came.

Ms. Falkner, who lives on the outskirts of Chicago, said she was grateful for the checks she received. But when they ended, she said, “They should have had some program in place to funnel those people back into the job market. Not to just leave them out there cold, saying, ‘The job market has improved, but there’s still 60,000 people in the city who can’t find one.’ ”
