Complexity And Crisis In The Financial System

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.

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.

In The Global Financial Crisis, contributors argue that the complexity of the Global Financial Crisis challenges researchers to offer more comprehensive explanations by extending the scope and range of their traditional investigations. To achieve this, the volume views the financial crisis simultaneously through three different lenses---economic, psychological, and social values. Contributors offer a constructive methodology suitable for exploring financial crises. They recognize how current economic analysis did not prepare academic economists, business economists, traders, and regulators to anticipate economic and financial crises. So, they search more extensively within the broader discipline of economics for ideas related to crises but neglected perhaps because they were not mathematically rigorous. They affirm that the complexity of financial crises necessitates complementary research. Thus, to put the focal purpose of this book differently, they explore the Global Financial Crisis from three interconnected frameworks: the standards of orthodox economic analysis, Minskyan economics, and the role of ideas and values in economics. Values are the subject of both philosophy and psychology and can contribute to a better understanding of the Global Financial Crisis. Values, in general, have been relatively neglected by economists. This is not because there is doubt about their significance, but rather because welfare economics and collective choice still operate within the neoclassical paradigm. This volume argues that analyzing the value implications requires moving from the neoclassical framework to something that is broader and multidisciplinary.

An in-depth look at how to account for the human complexities at the heart of today’s financial system Our economy may have recovered from the Great Recession—but not our economics. The End of Theory discusses why the human condition and the radical uncertainty of our world renders the standard economic model—and the theory behind it—useless for dealing with financial crises. What model should replace it? None. At least not any version we’ve been using for the past two hundred years. Richard Bookstaber argues for a new approach called agent-based economics, one that takes as a starting point the fact that we are humans, not the optimizing automatons that standard economics assumes we are. Sweeping aside the historic failure of twentieth-century economics, The End of Theory offers a novel perspective and more realistic framework to help prevent today's financial system from blowing up again.

Money and Finance After the Crisis provides a critical multi-disciplinary perspective on the post-crisis financial world in all its complexity, dynamism and unpredictability. Contributions illuminate the diversity of ways in which money and finance continue to shape global political economy and society. A multidisciplinary collection of essays that study the geographies of money and finance that have unfolded in the wake of the financial crisis Contributions discuss a wide range of contemporary social formations, including the complexities of modern debt-driven financial markets Chapters critically explore proliferating forms and spaces of financial power, from the realms of orthodox finance capital to biodiversity conservation Contributions demonstrate the centrality of money and finance to contemporary capitalism and its political and cultural economies

An in-depth look at how to account for the human complexities at the heart of today's financial system Our economy may have recovered from the Great Recession—but not our economics. In The End of Theory, Richard Bookstaber discusses why the human condition and the radical uncertainty of our world renders the standard economic model—and the theory behind it—useless for dealing with financial crises. What model should replace it? None. At least not any version we've been using for the past two hundred years. Instead, Bookstaber argues for a new approach called agent-based economics, one that takes as a starting point the fact that we are humans, not the optimizing automatons that standard economics assumes we are. Bookstaber's groundbreaking paradigm promises to do a far better job at preventing crises and managing those that break out. As he explains, our varied memories and imaginations color our economic behavior in unexpected hues. Agent-based modeling embraces these nuances by avoiding the mechanistic, unrealistic structure of our current economic approach. Bookstaber tackles issues such as radical uncertainty, when circumstances take place beyond our anticipation, and emergence, when innocent, everyday interactions combine to create sudden chaos. Starting with the realization that future crises cannot be predicted by the past, he proposes an approach that recognizes the human narrative while addressing market realities. Sweeping aside the historic failure of twentieth-century economics, The End of Theory offers a novel and innovative perspective, along with a more realistic and human framework, to help prevent today's financial system from blowing up again.

The scientific study of complex systems has transformed a wide range of disciplines in recent years, enabling researchers in both the natural and social sciences to model and predict phenomena as diverse as earthquakes, global warming, demographic patterns, financial crises, and the failure of materials. In this book, Didier Sornette boldly applies his varied experience in these areas to propose a simple, powerful, and general theory of how, why, and when stock markets crash. Most attempts to explain market failures seek to pinpoint triggering mechanisms that occur hours, days, or weeks before the collapse. Sornette proposes a radically different view: the underlying cause can be sought months and even years before the abrupt, catastrophic event in the build-up of cooperative speculation, which often translates into an accelerating rise of the market price, otherwise known as a "bubble." Anchoring his sophisticated, step-by-step analysis in leading-edge physical and statistical modeling techniques, he unearths remarkable insights and some predictions--among them, that the "end of the growth era" will occur around 2050. Sornette probes major historical precedents, from the decades-long "tulip mania" in the Netherlands that wilted suddenly in 1637 to the South Sea Bubble that ended with the first huge market crash in England in 1720, to the Great Crash of October 1929 and Black Monday in 1987, to cite just a few. He concludes that most explanations other than cooperative self-organization fail to account for the subtle bubbles by which the markets lay the groundwork for catastrophe. Any investor or investment professional who seeks a genuine understanding of looming financial disasters should read this book. Physicists, geologists, biologists, economists, and others will welcome Why Stock Markets Crash as a highly original "scientific tale," as Sornette aptly puts it, of the exciting and sometimes fearsome--but no longer quite so unfathomable--world of stock markets.
