To quote the study's author:
"Provide $2,000-lines of credit to every taxpayer, accessed through a government-issued credit card.
"The interest rate would be 6% per year, the money could be paid back over the course of 10 years, and the credit limit would gradually fall as the economy recovered and the stimulus from this extra borrowing power was no longer needed… most of the funds people borrow using these government-issued credit cards would eventually be repaid—particularly since the government can enforce repayment through payroll deduction. The unemployed would have their payments deferred, but once the economy is moving again, most people would have jobs with paychecks so they could repay… the stimulus effects of Federal Lines of Credit would be at worst only a little smaller than the stimulus from a $2,000 per person tax rebate.
"If 90% or more of everyone eventually repays, a $2,000 per person line of credit would ultimately cost less than $200 per person. With a good deal like that for getting the economy back in gear, maybe even Republicans and Democrats can agree on it."
