No, I would not exclude it. We have actually studied this carefully. We've been through a phase where many central banks had their interest rates at what we thought was the lowest possible level, but have actually worked with interest rates below zero to good effect. Europe, for example, is turning around nicely now. That is, in part, the product of negative interest rates, whereas there was very little by way of fiscal expansion.
That's to say there is some room to manoeuvre on the monetary side and probably more room to manoeuvre on the fiscal side. Moreover, we're in a state with the economy where fiscal policy has a greater impact because of where interest rates are.
