From the workings of financial markets to our response to the ecological crisis, economic theory shapes the world.But where do these ideas come from?Ricardo’s Dream tells the fascinating story of David Ricardo, Adam Smith’s only real rival as the ‘founder of economics’.The wealthiest stock trader of his day, Ricardo introduced the study of abstract models to economics.He also developed the theory of trade that underpinned globalization and hides, behind its mathematical facade, a history of power, empire, and slavery. Brimming with fresh ideas and stories, Ricardo’s Dream shows how too many economists, from Ricardo’s day to our own, have turned away from observing the real world and led us astray.
