Today I would like to suggest you check my previous posts on Angus Deaton, the economics Nobel prize winner. And if you have more time, a close reading of his book is required: The Great Escape: Health, Wealth, and the Origins of Inequality.
Angus Deaton deserves the prize -NYT dixit-. John Cassidy writes an excellent op-ed (The New Yorker) with the title: Angus Deaton: A Skeptical Optimist Wins the Economics Nobel. Nothing to add.
