Humor e Macroeconomia

Cheguei à equação de Euler. E agora? Como a maçã ou não?

Clues in our mitochondrial DNA tell biologists that we humans share a common ancestor called Eve who lived 200,00 years ago. All of macroeconomics too seems to have descended from a common source, Irving Fisher’s and Milton Friedman’s consumption Euler equation, the cornerstone of the permanent income theory of consumption. Modern macroeconomics records the fruit and frustration of a long love-hate affair with the permanent income mechanism. [Ljungqvist & Sargent (2010) Recursive Macroeconomic Theory, 3rd ed, p.3]

Taí um dos mais bem-humorados trechos da história da macroeconomia que eu já li.
