Very quickly, there are two factors. The slowing in the United States is a factor, but it's also that we reach our rate of potential growth, so the economy is equilibrated. If we want to grow faster.... It's unlikely we will improve our demographic profile, so it's a question of productivity.
Our judgment is that productivity growth, given where investment has been, would be about 1.4% per annum by 2012. So that is the key regulator on the rate of growth in this economy.
