“A History of Economic Theory offers a comprehensive account of the builders and building blocks of modern mainstream economics. Jurg Niehans shows how the analytical tools used by economists have evolved from the eighteenth century to the present. Niehans first surveys the development of classical economics from the scholastic and mercantilist traditions to Marx. He then follows the progress of marginalist economics from Thunen to Fischer. In the book's final section, he describes economic theory in the model-building era from Pigou and Keynes to Rational Expectations.”
