What are the differences between, QE1, QE2, and QE3?
Ed thinks that should QE3 come, it will be after the Fed has firmly established the the overnight rate at zero, when it will shape the yield curve by setting price rather than quantity, reversing the strategy of QE2.
If this happens it will be completely in line with MMT's position that the government controls interest rates as it chooses, and the natural rate of interest (overnight rate) is zero.
While this is admittedly an emergency measure, it demonstrates what MMT has been claiming as a feature of the federal government's monopoly power as issuer of a nonconvertible floating rate currency.
