Simeon is correct that Modern Monetary Theory (MMT) is currently being promoted by Stephanie Kelton, who would be the economic adviser for Bernie Sanders if elected by the way.
So what exactly is Modern Monetary Theory?
The basic idea as I have read and understood it is that government does not really need to have any constraint on funding whatever projects are necessary to get the economy going.
The federal government could issue however much currency it feels is necessary to print to fund large-scale socially useful projects.
There is a distinction between borrowing money to fund projects and printing money to fund projects.
Our current model is to borrow money which is the process of the federal government of the United States selling T-bonds and uses the proceeds to fund government spending. The Treasury pays the interest on those bonds. So like with any other borrowing that we may personally do, as borrowing rises, so do the payments on the interest and as these interest payments rise, it makes it difficult to engage in whatever spending the government wants.
There is another mechanism to government funding where the Federal Reserve can create money out of thin air by buying T-bonds and injecting new money into the economy.
MMT is saying we can bypass both paying interest on newly issued money and the monetization of debt, which is the second mechanism I described of the Federal Reserve buying T-bonds and just have the Treasury department print new currency directly.
As far as citing a paper, you need to do the research. You need to learn what are the economic policy journals out there. There is the European Journal of Economics and Economic Policy, Cambridge Journal of Economics, The Financial Times, the Wall Street Journal and so on. You can find an extensive list here:
