The sharing economy's unique customer-to-company exchange is possible because of the way in which money has evolved. These transactions have not always been as fluid as they are today, and they are likely to become even more fluid. It is therefore critical that we learn to appreciate money's elastic nature as deeply as do Uber, Airbnb, Kickstarter, and other innovators, and that we understand money's transition from hard currencies to cryptocurrencies like Bitcoin if we are to access their cooperative potential. The Evolution of Money illuminates this fascinating reality, focusing on the tension between currency's real and abstract properties and advancing a vital theory of money rooted in this dual exchange. It begins with the debt tablets of Mesopotamia and follows with the development of coin money in ancient Greece and Rome, gold-backed currencies in medieval Europe, and monetary economics in Victorian England. The book ends in the digital era, with the cryptocurrencies and service providers that are making the most of money's virtual side and that suggest a tectonic shift in what we call money.By building this organic time line, The Evolution of Money helps us anticipate money's next, transformative role.

In this sweeping book, applied mathematician and popular author David Orrell questions the promises and pitfalls of associating beauty with truth, showing how ideas of mathematical elegance have inspired—and have sometimes misled—scientists attempting to understand nature.Orrell shows how the ancient Greeks constructed a concept of the world based on musical harmony; later thinkers replaced this model with a program, based on Newton’s “rational mechanics,” to reduce the universe to a few simple equations. He then turns to current physical theories, such as supersymmetric string theory—again influenced by deep aesthetic principles. The book sheds new light on historical investigations and also recent research, including the examinations ongoing at the Large Hadron Collider. Finally, broadening his discussion to other fields of research, including economics, architecture, and health, Orrell questions whether these aesthetic principles reflect an accurate way to explain and understand the structure of our world.

Explore the deadly elegance of finance's hidden powerhouse The Money Formula takes you inside the engine room of the global economy to explore the little-understood world of quantitative finance, and show how the future of our economy rests on the backs of this all-but-impenetrable industry. Written not from a post-crisis perspective – but from a preventative point of view – this book traces the development of financial derivatives from bonds to credit default swaps, and shows how mathematical formulas went beyond pricing to expand their use to the point where they dwarfed the real economy. You'll learn how the deadly allure of their ice-cold beauty has misled generations of economists and investors, and how continued reliance on these formulas can either assist future economic development, or send the global economy into the financial equivalent of a cardiac arrest. Rather than rehash tales of post-crisis fallout, this book focuses on preventing the next one. By exploring the heart of the shadow economy, you'll be better prepared to ride the rough waves of finance into the turbulent future. Delve into one of the world's least-understood but highest-impact industriesUnderstand the key principles of quantitative finance and the evolution of the fieldLearn what quantitative finance has become, and how it affects us allDiscover how the industry's next steps dictate the economy's futureHow do you create a quadrillion dollars out of nothing, blow it away and leave a hole so large that even years of "quantitative easing" can't fill it – and then go back to doing the same thing? Even amidst global recovery, the financial system still has the potential to seize up at any moment. The Money Formula explores the how and why of financial disaster, what must happen to prevent the next one.

When Economyths was first published in 2010, David Orrell showed how mainstream economics is based on key myths such as fair competition, rational behaviour, stability and eternal growth - and how these myths lead paradoxically to their opposites: inequality, an irrational economy, financial instability and a collision with nature's limits.Since then, we've had Occupy, political upheaval, flash crashes in financial markets, the warmest few years in recorded history - and a growing chorus demanding fundamental reform. So how has economics responded?In this revised and expanded edition, Orrell shows how the ten myths still dominate economics. He reveals their roots in thought that goes back to the ancient Greeks, making them hard to dislodge. And he uncovers, demolishes and develops an alternative to the greatest economyth of all - the one that will lead to the collapse of orthodox economics.

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.

The controversial science that claims to have revolutionised economics.For centuries, economics was dominated by the idea that we are rational individuals who optimise our own 'utility'. Then, in the 1970s, psychologists demonstrated that the reality is a lot messier. We don't really know what our utility is, and we care about people other than ourselves. We are susceptible to external nudges. And far from being perfectly rational we are prone to 'cognitive biases' with complex effects on decision-making, such as forgetting to prepare for retirement. David Orrell explores the findings from psychology and neuroscience that are shaking up economics - and that are being exploited by policy-makers and marketers alike, to shape everything from how we shop for food, to how we tackle societal happiness or climate change. Finally, he asks: is behavioural economics a scientific revolution, or just a scientific form of marketing?

What do cacao beans, cowrie shells, paper cards, cigarettes and digital databases all have in common? At some time, they have been used as a form of money. Money is an essential aspect of everyday life and something that we usually take for granted until it all goes wrong. This book traces the role, growth and impact of money and finance on individuals, human civilisation and the type of economy we live in. The financial history of the world reads like a fascinating novel with innumerable twists and turns. We strive for financial stability and security, yet this often proves surprisingly ephemeral. Just as we hope we have reached a new plateau of prosperity, the financial system has a habit of throwing a spanner in the works, forcing us to change and adapt to new circumstances. This book traces the financial system from its birth as a credit system in ancient Mesopotamia, to the financial revolutions of the 20th and 21st centuries. This is the story of money, finance and economics but also its interaction with people, governments and society. Why did the American forces desperately try to destroy money during the American Revolution? Why do we tend to succumb to boom and busts? And if inflation is bad, why is deflation even worse? Also, the book looks at the effect money has on ourselves. Does money make us irrational? Is money really the root of all evil, or should we celebrate money for its potential to create prosperity and overcome poverty?

A comic-book introduction to economics from David Orrell, the author of Economyths: 11 Ways Economics Gets it Wrong. With illustrations from Borin Van Loon. Part of the internationally-recognised Introducing Graphic Guide series.Today, it seems, all things are measured by economists. The so-called 'dismal science' has never been more popular - or, given its failure to predict or prevent the recent financial crisis, more controversial.But what are the findings of economics? Is it really a science? And how can it help our lives?Introducing Economics traces the history of the subject from the ancient Greeks to the present day. Orrell and Van Loon bring to life the contributions of great economists - such as Adam Smith, Karl Marx, John Maynard Keynes and Milton Friedman - and delve into ideas from new areas such as ecological and complexity economics that are revolutionizing the field.
