In The Curse of Cash, Kenneth Rogoff, one of the world's leading economists, makes a persuasive and fascinating case for an idea that until recently would have seemed outlandish: getting rid of most paper money.Even as people in advanced economies are using less paper money, there is more cash in circulation--a record $1.4 trillion in U.S. dollars alone, or $4,200 for every American, mostly in $100 bills. And the United States is hardly exceptional. So what is all that cash being used for? The answer is simple: a large part is feeding tax evasion, corruption, terrorism, the drug trade, human trafficking, and the rest of a massive global underground economy.As Rogoff shows, paper money can also cripple monetary policy. In the aftermath of the recent financial crisis, central banks have been unable to stimulate growth and inflation by cutting interest rates significantly below zero for fear that it would drive investors to abandon treasury bills and stockpile cash. This constraint has paralyzed monetary policy in virtually every advanced economy, and is likely to be a recurring problem in the future.The Curse of Cash offers a plan for phasing out most paper money--while leaving small-denomination bills and coins in circulation indefinitely--and addresses the issues the transition will pose, ranging from fears about privacy and price stability to the need to provide subsidized debit cards for the poor.While phasing out the bulk of paper money will hardly solve the world's problems, it would be a significant step toward addressing a surprising number of very big ones. Provocative, engaging, and backed by compelling original arguments and evidence, The Curse of Cash is certain to spark widespread debate.

    Characterized by a range of new technologies that are fusing the physical, digital and biological worlds, the developments are affecting all disciplines, economies, industries and governments, and even challenging ideas about what it means to be human.Artificial intelligence is already all around us, from supercomputers, drones and virtual assistants to 3D printing, DNA sequencing, smart thermostats, wear­able sensors and microchips smaller than a grain of sand. But this is just the beginning: nanomaterials 200 times stronger than steel and a million times thinner than a strand of hair and the first transplant of a 3D printed liver are already in development. Imagine “smart factories” in which global systems of manu­facturing are coordinated virtually, or implantable mobile phones made of biosynthetic materials.The fourth industrial revolution, says Schwab, is more significant, and its ramifications more profound, than in any prior period of human history. He outlines the key technologies driving this revolution and discusses the major impacts expected on government, business, civil society and individu­als. Schwab also offers bold ideas on how to harness these changes and shape a better future—one in which technology empowers people rather than replaces them; progress serves society rather than disrupts it; and in which innovators respect moral and ethical boundaries rather than cross them. We all have the opportunity to contribute to developing new frame­works that advance progress.

    Now revised and updated to include expanded coverage of monetary policy, this volume traces the history of macroeconomics and the evolution of macroeconomic thought and the resulting theory and policy.
