Ludwig van Beethoven. Earth's bargaining chip?
Considering that we have been immersing ourselves in Beethoven, I was pretty amused to see this bit (Tyler Cowen is interviewing Paul Krugman for a podcast):
KRUGMAN: I wrote a paper on the theory of interstellar trade when I was an unhappy assistant professor. Are there any happy assistant professors? [laughs] I was just blowing off steam. But it’s an interesting question.
COWEN: It could become your most important paper, right? [laughs]
The "Conversations with Tyler" podcast is quite good; there's a wide variety of guests. I like Episode 21, the interview with Cowen himself.
