The Joke
A woman is presenting results from a macroeconomic model. The model's prediction is that "the economy will crash because of the horror of existence in a vast and doomed cosmos." This is absurd because macroeconomic models predict outcomes based on factors like interest rates, employment, and GDP -- not existential dread about the nature of the universe.
The caption below delivers the punchline: "The fact that this never happens is proof that economic models don't really assume all agents have perfect information." In economics, many models assume "rational agents with perfect information," meaning every participant in the economy knows all relevant facts. The joke is that if people truly had perfect information -- including full awareness of humanity's insignificance in an indifferent cosmos -- the rational response would be despair, and the economy would collapse.
The Humor
The comic works on two levels. First, it satirizes the well-known (and often criticized) economic assumption that all agents are perfectly rational and perfectly informed. Second, it plays on the classic SMBC theme of existential nihilism: that full awareness of reality should logically lead to paralysis and horror, and the fact that we all keep going to work and buying things is proof that we are blissfully ignorant. The deadpan academic presentation style makes the existential crisis all the funnier.
