On the TCS stack-exchange, Ryan Williams asked “What papers should everyone read” . One of the papers suggested as an answer is in Economics (some may even say in Algorithmic Game Theory): Paul Krugman’s 1978 paper on “A Theory of Interstellar Trade” still stings.
Turing's Invisible Hand 
That is a pretty funny paper, thanks for pointing to it. For those of us who weren’t born yet then, would it still sting?
Slightly more seriously, it seems inevitable to me that with so many academics around the world being asked to publish to have their choice of job, people do more problem-inventing than problem-solving on average. One could be pretentious about it or honest. If one is honest and makes some effort that the problem-inventing is creative, intellectually stimulating, and within a few steps of applicability, is that reasonable?
Part of the sting that I feel comes from my realization that I would happily accept such a paper to an AGT conference — even if it was not also funny — despite its absurdity since it is so elegant….
Krugman did a great work unifying the theory of international trade with the theory of industrial organization. This work gaved him a well deserved Nobel prize. The paper you link to, no doubt, deserves an IG Noble.
This year we had a researcher traversing the route
IG Noble–>Noble. We need now an Noble–>IGNoble and Krugman would have been a good candidate had he published this paper after his Noble.
Hmmm…why not generalize this paper to interuniverse trade using M-theory ? I remaind have heard of one researcher named Garkmun which traversed this path precisely this way in the 10^500 nth universe…
It is an interesting paper, but left me wanting more. Especially, the special relativity formulae which associate the physical quantities on the ship (such as time, which is the main topic of study) with the observation of the same phyical quantities from Earth/Tranton inertial frame. Economical quantities such as interest rate may have similar formulae.
Also, it is assumed that interest rates remain log-additive, which is true in the classical world. But in the classical world, relative speeds are also additive, which is shown to be incorrect by Einstein. So if the interest rates also do not satisfy the log-additive then the formulae would be even more interesting.
