A decade after the financial crisis, there is a growing consensus that economics has failed and needs to go back to the drawing board. David Orrell argues that it has been trying to solve the wrong problem all along. Economics sees itself as the science of scarcity. Instead, it should be the science of money (which plays a surprisingly small role in mainstream theory). And money is a substance that turns out to have a quantum nature of its own. Just as physicists learn about matter by studying the exchange of particles at the subatomic level, so economics should begin by analysing the nature of money-based transactions. Quantum Economics therefore starts with the meaning of the phrase 'how much' – or, to use the Latin word, quantum. From quantum physics to the dualistic properties of money, via the emerging areas of quantum finance and quantum cognition, this profoundly important book reveals that quantum economics is to neoclassical economics what quantum physics is to classical physics – a genuine turning point in our understanding.

This book provides an introduction to how the mathematical tools from quantum field theory can be applied to economics and finance. Providing a range of quantum mathematical techniques for designing financial instruments, it demonstrates how a range of topics have quantum mechanical formulations, from asset pricing to interest rates.

The word "quantum" is from the Latin for "how much" and in this book mathematician David Orrell shows how it applies to the world of economic transactions. Written in clear and accessible language, the book covers the essential mathematics behind topics such as quantum cognition, option pricing, and quantum game theory, and delves into the nuts and bolts of quantum mechanics, the principles of quantum economic modelling, and the basics of quantum computation. On the way the reader will learn how quantum interference can be used to model cognitive dissonance, how a quantum walk goes further than a random walk, and how financial entanglement explains the rate of mortgage default. It is aimed at anyone who wants to understand the quantum ideas working their way into economics and finance, without getting drowned in wave equations. As interest in quantum computing grows, many companies from established banks to startups are looking at ways to perform financial simulations using quantum algorithms. But what if we should be using quantum models anyway - because the monetary system has quantum properties of its own, and because they work? The field is developing rapidly, and this second edition contains many updates including new material on quantum logic and quantum agent-based models, and a guest chapter from Ramy Aboushelbaya and Marko Mayr of Quantum Dice on quantum hardware. David Orrell is an applied mathematician with extensive experience in mathematical modelling, and the author of a dozen books on science and economics.

From Simon & Schuster, Microcosm is the provocative national bestseller by the author of Wealth and Poverty. George Gilder's Microcosm is the crystal ball of the next technological era. Leading scientists, engineers, and entrepreneurs provide vivid accounts of the latest inventions, revealing how the new international balance of power really lies in information technology.

Quantum Macroeconomics presents a new paradigm in macroeconomic analysis initiated by Bernard Schmitt. It explains the historical origin, the analytical contents, and the actual relevance of this new paradigm, with respect to current major economic issues at national and international level. These issues concern both advanced and emerging market economies, referring to inflation, unemployment, financial instability, and economic crises. In the first part of this volume, leading scholars explain the historical origin and analytical content of quantum macroeconomics. The second part explores its relevance with respect to the current major economic issues such as the sovereign debt crisis and European monetary union. The volume also features two previously unpublished papers by Bernard Schmitt. The main findings of this book concern the need to go beyond agents’ behaviour to understand the structural origin of a variety of macroeconomic problems, notably, inflation, unemployment, financial instability, and economic crises. The originality that pervades all contributions is plain, when one considers the lack of any structural explanation of national and international economic disorders in the literature within the mainstream approach to economics. This edited volume is of great interest to those who study macroeconomics, monetary economics and money and banking.

The Old Economy is dead. So is the New Economy Algorithms are increasingly becoming authorities and competing directly with humans. Recommendation engines have long taken control of our lives. We are threatened by a final narcissistic injury, and we are alienated by the fatal information society that we live in. But humans are still the 'gluons' that connect our perceived reality – the environment, society, and the economy – with our inner world: what it means to be a human being, a Mensch. If we want to ensure that the machines continue to serve us after the digital tsunami, then now is the time to leverage the full power of our reason to build a humanistic society. "A must-read for anyone who does not just want to see the future, but wants to be an active part of it." Marshall Goldsmith, Two-time Thinkers 50 #1 Leadership Thinker "Anders Indset's thought-provoking new book is a must-read, and one I wish I had read prior to the outbreak of the pandemic." Dorie Clark, author of "Reinventing You" and Member of Executive Education Faculty Duke University Fuqua School of Business. "The Quantum Economy is a highly timely and truly relevant book. This new world – with Covid-19 and all the panic following it – begs us all to redefine how we live and how we do business. A must read for anyone in search for meaning in how to run businesses." Martin Lindstrom, New York Times best-selling author of Small Data and Buyology "The quantum economy opens up new perspectives on the economy of today and tomorrow - and on how our economy affects society. An inspirational reading that stimulates discussion and leaves a lasting impression." Yves Pigneur, Professor of Management Information Systems, University of Lausanne
