Which economist suggested solely printing money to borrow and not have bonds? 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.
I think that Stephanie Kelton is an economist who has mentioned this before. From my research, it is based on the MMT. Some practitioners of the MMT believe that the government should not issue bonds, but can instead print money. I think that I may have heard Kelton mention this a few years ago, but I am not that into the MMT. I would do some research on the MMT however, and Kelton, and that can likely lead you to the answer you're looking for.
