Let me attempt, perhaps foolhardily, to map out a scenario of how the global economic crisis could evolve in continental Europe.
Even if we assume a recovery elsewhere, Europe’s economy may be stuck at low growth for some time. To understand why, it is perhaps best to look at sectoral balances for households, companies and the public sector.
The current account can be expressed as the difference between national savings and investments. Of the world’s 10 largest economies, the US, the UK and Spain used to run the largest current account deficits before the crisis. The US household sector has been shifting from a negative savings rate before the crisis to a positive rate of 4 per cent of disposable income now. The US corporate sector used to have a large negative savings rate, but this has almost disappeared. So far, the increase in net savings in the US private sector has been balanced by increased borrowing from the US government.
I am making three assumptions: the first is that the return to a positive US household savings rate is permanent – even under a scenario of a strong economic recovery. US households will take time to repair their balance sheets after the housing and credit disaster. Second, I also expect US companies not to return to the high level of borrowings that prevailed before the crisis. Third, I expect the US government to reduce its deficit after 2010. The recent rise in long-term bond yields should serve as a reminder that deficits cannot go on rising forever.
