A masterly introduction to the key ideas behind the successes-and failures-of free-market economics. Since 1946, Henry Hazlitt's bestselling Economics in One Lesson has popularised the belief that economics can be boiled down to one simple lesson: market prices represent the true cost of everything. But one-lesson economics tells only half the story. It can explain why markets often work so well, but it can't explain why they often fail so badly — or what we should do when they stumble. As Nobel Prize-winning economist Paul Samuelson quipped, 'When someone preaches Economics in one lesson, I advise: Go back for the second lesson.' In Economics in Two Lessons, John Quiggin teaches both lessons, offering a masterly introduction to the key ideas behind the successes — and failures — of free markets. Brilliantly accessible, this book unlocks the essential issues at the heart of any economic question.
