I will then show that an increase in the money supply can increase employment, despite zero nominal interest rates.

If financial markets were perfect, quantitative easing would have no effect on aggregate demand. But if financial markets were perfect, we wouldn't have the financial crisis, and so wouldn't need quantitative easing.

We need to move outside the Neo-Wicksellian perspective if we want to look at monetary policy where short-term interest rates are already at zero. You can't use a model which contains i and does not […]
