The book that built the modern economy

250 years ago, on the 9th of March 1776, a book was published that didn’t just explain the economy, it changed it. The Wealth of Nations, written by "the father of economics" Adam Smith, sparked debates that still rage today, shaping everything from global trade to how much you earn.

Rob Young looks at an original copy from 1776, assesses Smith's importance, and speak to economists about the state of Adam Smith's free market today.
