This book explores money as a system of "tokens" that represent the purchasing power of individual agents. It looks at how money developed from debt/credit relationships, barter and coins into a system of gold-backed currencies and bank credit and on to the present system of fiat money, bank credit, near-money and, more recently, digital currencies. The author successively examines how the money circuit has changed over the last 50 years, a period of stagnant wages, increased household borrowing and growing economic complexity, and argues for a new theory of economies as complex systems, coordinated by a banking and financial system. Money: What It Is, How It’s Created, Who Gets It and Why It Matters will be of interest to students of economics and finance theory and anyone wanting a more complete understanding of monetary theory, economics, money and banking.
