During a seminar on climate change and optimal discount rates, professor Joseph Stiglitz reminds himself of an anecdote:
“Two planets meet. The first one asks: ‘How are you?’
‘Not so well,’ the second planet replies. ‘I’ve got the Homo sapiens.’
‘Don’t worry,’ the first planet says, ‘I’ve had it before. It doesn’t last long.'”
