Economic analyses of intergalactic trade

A new paper on the potential pitfalls of interstellar trade prompts economist bloggers Tyler Cowen and Joshua Gans to look at some of the recent and not so recent economic treatises on the subject.

I love this quote from a Paul Krugman paper on the topic:

It should be noted that, while the subject of this paper is silly, the analysis actually does make sense. This paper, then, is a serious analysis of a ridiculous subject, which is of course the opposite of what is usual in economics.
