Menzie Chinn at Econbrowser breaks down US import data by sector to argue the following (see entire article here):
What is clear is that consumer goods do not vary that much; now, part of auto and auto parts is going to satisfy consumer demand as well, and here we do have some evidence in support of the hypothesis of the consumer going back to his/her old ways of sucking in imports.
...
Consumption hardly seems resurgent, so attributing the increase in imports to consumers means that one is assuming a very high share of imports to incremental consumption -- something I'm not sure makes sense. So, I think the book is still open on whether the consumer is going to drive the US back into a rapidly expanding trade deficit.
Another way to look at this is by comparing global household saving rates. Specifically, I look at the household saving rates across the US (the world's largest economy in 2007, as measured in
PPP dollars - download the data at the IMF
World Economic Outlook database), UK (6
th largest economy), Canada, and Germany (5
th largest economy).
The household saving ratio is calculated as gross household saving divided by personal disposable income, as reported in country National Accounts.If the global economy is indeed "
rebalancing", then relative to disposable income the
big spenders (US, UK) raise saving, while the big savers (Germany) increase spending. In contrast, if the global economy is returning to the
pre-crisis "status
quo", then relative to disposable income household saving rate would:
- fall in the US and UK
- rise in Germany
(Using IMF data, here's
a chart that I put together last year of consumption shares across economies to illustrate the big spenders and big savers.)
The German household saving rate is rising, while the UK households saving rate is falling. In the US, we're seeing the household saving rate stabilizing above
pre-crisis levels, even increasing at the margin.
