eulogy
Explanation
This single-panel comic shows a funeral scene. A speaker at the podium says, "...and although we are sad at his passing, we can take comfort in knowing that Erik's revealed preference is apparently death."
The caption reads: "Economists give the best funeral speeches."
The joke hinges on the economic concept of "revealed preference," a theory which states that people's true preferences are revealed by their actual choices and behavior, rather than by what they say they prefer. By this logic, since Erik died (and presumably did not take every possible measure to avoid death), an economist would conclude that Erik's "revealed preference" -- what his behavior indicates he actually wanted -- was death.
This is a reductio ad absurdum of revealed preference theory. Taken literally, the theory would imply that any outcome a person experiences must be their preferred outcome, since they didn't act to prevent it. The comic satirizes how economists can take a reasonable analytical framework and, by applying it too rigidly, arrive at conclusions that are both logically defensible and emotionally monstrous -- such as telling mourners at a funeral that the deceased apparently wanted to die.
