“Global imbalances matter” seems to be the favoured warcry over at Brad Setser’s blog these days (I’m not sure anyone really disagrees with the idea that they matter, all the arguing seems to be about how much and why). Recently however Brad seems to be drawing support from a rather unexpected quarter: “one part of the Economist” (well, one part is definitely better than none), the part which believes that despite what happened in 2005, 2006 will be the year of the “great dollar decline”: And why would this be? Because, of course, global imbalances do (here read the US CA deficit), in fact, matter.
However this issue is more interesting, since the part of the Economist which believes that the US CA deficit will prove decisive in 2006, also seems to believe that global ageing isn’t in fact a terribly important phenomenon (and here).
The Economist seems to take the view – as Claus Vistesen puts it – that “Rich countries’ populations are shrinking … not to worry though“?
In fact Claus seems much nearer the mark than the part of the Economist which seems to be arguing that ageing doesn’t matter too much when he says:
I agree with the zest of their arguments, namely that the new realities mean that there will be fewer people in the workforce to support more old people in the future. In a global perpspective I also believe that the world would benefit from having fewer people on the whole. However, the point that escapes The Economist in the midst of their optimism is that some countries will have a hell of a lot more difficulties adapting than others, and as such these demographic trends might have a real negative effect, at least some places in the world.
Yes, I would say that this is just the point that escapes the ‘ageing doesn’t matter so much’ part of the Economist, who seem to believe that population meltdown in Japan wouldn’t be a problem since “the last Japanese will (only) die as soon as 2800.” (Actually the article on Japan is near to scandalous, since it only focuses on the legal minimum pensionable age, and misses entirely the important point that most Japanese already continue working after 65, and even by the age of 75 25% of the population are still working).
I have already posted extensively on the population turning point in Japan (and here). So now I would simply make two points. Firstly it is the age structure of the population which matters, not its size, and secondly, it is curious how all those people who seem to want to argue that the US current account deficit is the most important determinant of today’s global economy also feel themselves impelled to downplay (if not actually try to ridicule) the idea that changing global demography (from Bolivia, to Vietnam, to Turkey, to China, to France, to Germany, to Japan) has any important role to play in helping us understand current economic phenomena. I think there is a choice here: two world-views are colliding, and the paths are forking.
