The problem with this statement is that so-called long-run tendencies (like
purchasing power parity) aren't likely to turn up unless short-run forces
(real-world trading in acutal historical time) are somehow driving things
in the right direction.
Efficient market types try desperately to put a good face on foreign
exchange markets by claiming that everything will make sense in the long
run. All real-world evidence contradicts this. I find it most helpful to
regard the exchange rate as a purely speculative variable --hanging by it's
bootstraps. Sometimes speculation is stabilizing, moving to correct
obvious problems of over-
and under-valuation. This is what efficient market boosters would have us
believe. Korea, Indonesia, Mexico, et al, were victims of nothing more than
way-overdue market "corrections" to long-run equilibrium.
Then again, sometimes speculation is distabilizing. I would say the won,
rupiah, baht, ruble, peso all fell victim to destabilizing speculators. The
Clinton administration is, just now, arranging a tax-financed,
$30b pay-off to keep destabilizing speculators from bringing down the real.
How much easier (and cheaper) to just control currency trading.
