Samuelson on Mankiw, dollar, and bubbles

Part II of an interview with Samuelson:
In one of Greg Mankiw's articles, he said that maybe when the interest rate gets down to zero and it's threatening to be negative, you should give a subsidy with it. Well, that's what fiscal policy is!

I think it's almost inevitable that, with a billion people in China wide awake for the first time, and a billion people in India, there's going to be some kind of a terrible run against the dollar. And I doubt it can stay orderly, because all of our own hedge funds will be right in the vanguard of the operation. And it will be hard to imagine that that wouldn't create different kind of meltdown.

But there never has been a true macro efficient market. You just have to look at the record of economic history the ups and downs. Bubbles are self-generating. And I'm not sure most of the people that get caught up in the middle of a bubble can be described as irrational. It seems pretty rational to buy a house and flip it in the next few weeks at a profit when that's been happening for along time. It works both ways.

I think it would be surprising if, down the road -- not in the long long run but in the somewhat short run -- we don't have some return of inflation. On the other hand, I'm of the view that if we come out of this with some kind of temporary stabilization at least, and the price level is let's say 10-12% above what it was before we got into the meltdown, I think that's a price I would be willing to pay!

I'm against inflation, but what I worry about is continuing, galloping, self-reinforcing inflation. I would not try to roll things back to some sacred earlier price level.
