What are the long-term causes and consequences of the global financial crisis of 2007–2008? This book offers a fresh perspective on these issues by bringing together a range of academics from law, history, economics and business to look in more depth at the changing relationships between crises and complexity in the US and UK financial markets. The contributors are motivated by three main questions: • Is the present financial system more complex than in the past and, if so, why? • To what extent, and in what ways, does the worldwide financial crisis of 2007–2008 differ from past financial crises? • How can governments, regulators and businesses better manage and deal with increased levels of complexity both in the present and in the future? Students and scholars of finance, economics, history, financial law, banking and international business will find this book to be of interest. It will also be of use to regulators and policymakers involved in the US and UK banking sectors.

This book includes contributions about mathematics, physics, philosophy of science, economics and finance and resulted from the Summer School “Complexity and Emergence: Ideas, Methods, with a Special Attention to Economics and Finance” held in Lake Como School of Advanced Studies, on 22–27 July 2018. The aim of the book is to provide useful instruments from the theory of complex systems, both on the theoretical level and the methodological ones, profiting from knowledge and insights from leading experts of different communities. It moves from the volume editors' conviction that to achieve progress in understanding socio-economical as well as ecological problems of our complex word such preparation is needed, together with a critical reconsideration of our basic scientific and economical approach. The potential readers are primarily master and doctorate students of mathematics, information sciences, theoretical physics and economics, as well as research workers in those areas, who want to enlarge their spectrum of knowledge towards the area of complexity and emergence. Since ideas and methods of the theory of complex systems also apply to other areas (from engineering and architecture to biology and medicine, e.g.), students and research workers from those areas will also profit from this book.

In recent years, technology has emerged as a disruptive force in the economy and finance, leading to the establishment of new economic and financial paradigms. Focusing on blockchain technology and its implementations in finance, Technology in Financial Markets proposes a novel theoretical approach to disruption. Relying on complexity science, it develops a dynamic perspective on the study of disruptive phenomena and their relationship to financial regulation and the law. It identifies the intrinsic interconnections characterizing the "multidimensional" technology-driven transformations, involving commercial practices, capital markets, corporate-governance, central banking, and financial networks. From this perspective, it considers the way they are reflected at the level of contract law, financial law, corporate law, central banking law. The book adopts a unique comparative approach and explains and clarifies the factual and historical dimensions underlying the emergence of the crypto-economy. In this book blockchain is used as a case study. Blockchain exemplifies the way each subpart of the financial system - commercial practices, financial markets, corporations, central banking, networks - and consequently each subcategory of financial regulation evolves on an individual basis. It shows how such subparts evolve altogether bringing systemic transformations, and ultimately leading to the creation of new economic and financial paradigms. The book considers both these perspectives, analysing the evolution of each subpart and emphasizing the interconnected transformations. In doing this, it adopts the structure of an ascending climax, starting from contracts, and escalating to increasingly broad dimensions, in particular capital markets, corporate governance, central banking, and financial networks.

The book is motivated by the disruptions introduced by the financial crisis and the many attempts that have followed to propose new ideas and remedies. Assembling contributions by authors from a variety of backgrounds, this collection illustrates the potentials resulting from the marriage of financial economics, complexity theory and an out-of-equilibrium view of the economic world. Challenging the traditional hypotheses that lie behind financial market functioning, new evidence is provided about the hidden factors fuelling bubbles, the impact of agents’ heterogeneity, the importance of endogeneity in the information transmission mechanism, the dynamics of herding, the sources of volatility, the portfolio optimization techniques, the financial innovation and the trend identification in a nonlinear time-series framework. Presenting the advances made in financial market analysis, and putting emphasis on nonlinear dynamics, this book suggests interdisciplinary methodologies for the study of well-known stylised facts and financial abnormalities. This book was originally published as a special issue of The European Journal of Finance.

The proceedings of the 2017 Symposium on Chaos, Complexity and Leadership illuminate current research results and academic work from the fields of physics, mathematics, education, economics, as well as management and social sciences. The text explores chaotic and complex systems, as well as chaos and complexity theory in view of their applicability to management and leadership. This proceedings explores non-linearity as well as data-modelling and simulation in order to uncover new approaches and perspectives. Effort will not be spared in bringing theory into practice while exploring leadership and management-laden concepts. This book will cover the analysis of different chaotic developments from different fields within the concepts of chaos and complexity theory. Researchers and students in the field will find answers to questions surrounding these intertwined and compelling fields.

You will find in this book exclusive interviews of renowned specialists about market microstructure and high-frequency trading strategies on lit markets and Dark Pools. This book was developed following extensive research to democratize as many aspects as possible on US and European market microstructure, high-frequency trading strategies and Dark Pools. Today, financial markets have become extremely complex. Market automation and new regulations have encouraged the emergence of new market players: high-frequency traders. These new players hold intraday positions. They deploy their specific orders and arbitrage strategies across multiple markets at close to the speed of light to get the best prices and to trade ahead of other market participants. Dark Pools, whose operations are also difficult to understand for most professionals, have been created, adding complexity to financial markets. Dark Pools seems a little bit scary. However, we will see that Dark Pools are advantageous in terms of price compared to regulated markets. “Fantastic job explaining some tough to understand topics.” – Joe Saluzzi, Partner and co-founder of Themis Trading and co-author of the book Broken Markets. William’s message: “High-frequency trading is a small world that is difficult to access. I have spent a large part of this last year writing this book, taking into account the interviews I have been able to carry out in order to democratize as many aspects as possible. Many thanks to Joe Saluzzi, Alexandre Laumonier, Dave Lauer, Benoît Lallemand, Jean-Philippe Bouchaud and Donald MacKenzie. This book will help you to better understand the winning strategies of high-frequency trading firms.”

There is no term that better describes the essential features of human society than complexity. On various levels, from the decision-making processes of individuals, through to the interactions between individuals leading to the spontaneous formation of groups and social hierarchies, up to the collective, herding processes that reshape whole societies, all these features share the property of irreducibility, i.e., they require a holistic, multi-level approach formed by researchers from different disciplines. This Special Issue aims to collect research studies that, by exploiting the latest advances in physics, economics, complex networks, and data science, make a step towards understanding these economic and social systems. The majority of submissions are devoted to financial market analysis and modeling, including the stock and cryptocurrency markets in the COVID-19 pandemic, systemic risk quantification and control, wealth condensation, the innovation-related performance of companies, and more. Looking more at societies, there are papers that deal with regional development, land speculation, and the-fake news-fighting strategies, the issues which are of central interest in contemporary society. On top of this, one of the contributions proposes a new, improved complexity measure.

This book is a review on the economic theories of systemic risks in the financial market and the topics in constructing the macroprudential framework for banking regulation in the future. It explains the reasons why the traditional microprudential regulatory framework missed its target in stabilizing the market and preventing the crisis, and discusses the principles and instruments for designing macroprudential rules.

This collection of essays explores the different ways the insights from complexity theory can be applied to law. Complexity theory – a variant of systems theory – views law as an emergent, complex, self-organising system comprised of an interactive network of actors and systems that operate with no overall guiding hand, giving rise to complex, collective behaviour in law communications and actions. Addressing such issues as the unpredictability of legal systems, the ability of legal systems to adapt to changes in society, the importance of context, and the nature of law, the essays look to the implications of a complexity theory analysis for the study of public policy and administrative law, international law and human rights, regulatory practices in business and finance, and the practice of law and legal ethics. These are areas where law, which craves certainty, encounters unending, irresolvable complexity. This collection shows the many ways complexity theory thinking can reshape and clarify our understanding of the various problems relating to the theory and practice of law.

How does America manage crisis on behalf of international finance in the absence of a global state? Doyran explores the relationship between state power and global finance and in particular examines the various attempts by the US state at financial crisis management. The case studies highlight the dramatic consequences of the rise of financial capitalism in the US economy, and also explore regulatory sources of market failures, systemic risk and moral hazard. This book focuses on this primary issue facing scholars of American power in various social science disciplines, including political science, finance and international relations, professional financial analysts and Government officials. This book is for the critical reader who is interested in financial policy and wants to learn more about the causes and consequences of the rise of financial markets.
