Economics Joke

Keynes and Krugman are walking. Keynes says, “I’ll pay you $5,000 to eat a dog turd.” Krugman does it. Keynes doesn’t have any evil savings and didn’t think Krugman would do it: The next day he begs for the money back. Krugman says, “I’ll give it back if you eat a turd.” Keynes does it. Krugman says, “That was stupid: No one made money and we’ve both eaten sh*t.” Keynes says: “But we boosted GDP by $10,000.”
