I remember reading this really interesting idea by some economist that a government need not issue fixed-term debt such as bonds, notes or bills. Instead all it could do is print money and use it to pay for everything, thereby borrowing.
It would repay by levying taxes, which it would vary based on the rate of inflation. I. e. if the rate of inflation would be too high, it would increase tax rates to bring it down and vice versa.
My question is -- who was this economist? I need to cite this idea and need a name or better yet a citation to a paper.
