Jonah: I don’t think there is enough disagreement here–or in my case,

knowledge–to justify taking this thread any further. You did stop me

dead, though, with that metaphor about Krugman having “his dress over his

head.” It is a metaphor, isn’t it? And how do I get rid of the mental

image it conjures up? I have tried whanging my head against the door jamb,

but that doesn’t work.
