In recent years a new approach to macroeconomics has been developed that challenges conventional wisdom and uncovers how money "works" in the modern economy. This book synthesises the key principles of Modern Money Theory, exploring macro accounting, currency regimes and exchange rates in both the USA and developing nations. Randall Wray addresses the pressing issues of how misunderstandings about the nature of money have caused the current global financial meltdown, and provides fresh ideas about how policymakers around the world should address the continued weaknesses in their economies.
