This is always tricky, because at the bank we really don't work on that, and I have to be here to speak about the work we do.
What we focus on is the importance of fiscal balance, and in particular we focus on this at a time when we have stronger than anticipated growth. Clearly, then, we would look for governments to be running surpluses.
That's what's critical for us. Over the longer term, tax structure is critical to the economy's potential growth rate, but we are not experts in this.
