Samuelson: Preferência Temporal Simétrica e Assimétrica

Um artigo recente de Paul Samuelson sobre a taxa de disconto intertemporal e a economia comportamental. Leitura obrigatória onde podemos encontrar uma pérola destas: "Karl Marx (1867) espoused the “heretical” position that machinery and factories were merely “dead (past) labor” which was undeserving of a net permanent share of the social harvest. He must have surmised this on a bad-hair day, but never did he escape from his own brainchild".
