This book uses simple, non-mathematical economic models to analyze poverty in India. The authors' basic idea is that reducing India's high labor/land ratio is the only way to raise living standards for hundreds of millions of Indians who live below the poverty line. Along the way, the authors give incredibly clear explanations of basic economic concepts like marginal product, general equilibrium, and comparative advantage. They also use their models to provide a fascinating explanation of why free trade with Britain probably increased poverty in India in the 18th and 19th centuries. I gave the book four stars instead of five only because the discussion of contemporary policy issues is dated and overly-anecdotal. Otherwise, this book is a small gem of exposition and analysis. If only all economists wrote this well.
