In 2008, Paul Krugman won the Nobel Prize in Economics for his contributions to New Trade Theory and New Economic Geography, but back in 1978, as a mere assistant professor at Yale, he wrote a parody of an academic paper about interstellar trade theory.
The paper claims to prove with "two useless but true theorems" and boasts that it "is a serious analysis of a ridiculous subject, which is of course the opposite of what is usual in economics."
As a youth, Krugman was inspired to become an economist after reading Isaac Asimov's Foundation novels, which explains the mention of Trantor.
The paper also claims the research was supported by a grant from the Committee to Re-Elect William Proxmire. Here's the joke: Senator Proxmire (D-Wis.) did not accept any campaign donations in 1976 (or 1982, for that matter) and spent less than $200 out of his own pocket for filing expenses. He won with 73% of the vote. Those were different times.
