Available in PDF, EPUB and Kindle. Book excerpt: A new, evolutionary explanation of markets and investor behavior Half of all Americans have money in the stock market, yet economists can’t agree on whether investors and markets are rational and efficient, as modern financial theory assumes, or irrational and inefficient, as behavioral economists believe. The debate is one of the biggest in economics, and the value or futility of investment management and financial regulation hangs on the answer. In this groundbreaking book, Andrew Lo transforms the debate with a powerful new framework in which rationality and irrationality coexist—the Adaptive Markets Hypothesis. Drawing on psychology, evolutionary biology, neuroscience, artificial intelligence, and other fields, Adaptive Markets shows that the theory of market efficiency is incomplete. When markets are unstable, investors react instinctively, creating inefficiencies for others to exploit. Lo’s new paradigm explains how financial evolution shapes behavior and markets at the speed of thought—a fact revealed by swings between stability and crisis, profit and loss, and innovation and regulation. An ambitious new answer to fundamental questions about economics and investing, Adaptive Markets is essential reading for anyone who wants to understand how markets really work.
Download or read book Evolutionary Strategic Beliefs and Financial Markets written by Elyes Jouini and published by . This book was released on 2015 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: We provide a discipline for belief formation through an evolutionary process which favors beliefs leading to higher utility levels at the Walrasian equilibrium. We show that such an evolutionary process converges to the Nash equilibrium in a game of strategic beliefs choices. The asymptotic beliefs are subjective and heterogeneous across the agents. Optimism (resp. overconfidence) as well as pessimism (resp. doubt) both emerge from the evolutionary process. Furthermore, we obtain a positive correlation between pessimism (resp. doubt) and risk-tolerance. We analyze the equilibrium characteristics. Under reasonable assumptions, the consensus belief is pessimistic and, as a consequence, the risk premium is higher than in a standard setting.

Available in PDF, EPUB and Kindle. Book excerpt: The models of portfolio selection and asset price dynamics in this volume seek to explain the market dynamics of asset prices. Presenting a range of analytical, empirical, and numerical techniques as well as several different modeling approaches, the authors depict the state of debate on the market selection hypothesis. By explicitly assuming the heterogeneity of investors, they present models that are descriptive and normative as well, making the volume useful for both finance theorists and financial practitioners.

Download or read book New Evolutionary Finance written by Erol Akcay and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The thoughts and behaviors of financial market participants depend upon adopted cultural traits, including information signals, beliefs, strategies, and folk economic models. Financial traits compete to survive in the human population, and are modified in the process of being transmitted from one agent to another. These cultural evolutionary processes shape market outcomes, which in turn feed back into the success of competing traits. This evolutionary system is studied in an emerging paradigm, new evolutionary finance. In this paradigm, social transmission biases determine the evolution of financial traits in the investor population. It considers an enriched set of cultural traits, both selection on traits and mutation pressure, and market equilibrium at different frequencies. Other key ingredients of the paradigm include psychological bias, social network structure, information asymmetries, and institutional environment.
Download or read book An Evolutionary Theory of Economic Change written by Richard R. Nelson and published by Harvard University Press. This book was released on 1985-10-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the most sustained and serious attack on mainstream, neoclassical economics in more than forty years. Nelson and Winter focus their critique on the basic question of how firms and industries change overtime. They marshal significant objections to the fundamental neoclassical assumptions of profit maximization and market equilibrium, which they find ineffective in the analysis of technological innovation and the dynamics of competition among firms. To replace these assumptions, they borrow from biology the concept of natural selection to construct a precise and detailed evolutionary theory of business behavior. They grant that films are motivated by profit and engage in search for ways of improving profits, but they do not consider them to be profit maximizing. Likewise, they emphasize the tendency for the more profitable firms to drive the less profitable ones out of business, but they do not focus their analysis on hypothetical states of industry equilibrium. The results of their new paradigm and analytical framework are impressive. Not only have they been able to develop more coherent and powerful models of competitive firm dynamics under conditions of growth and technological change, but their approach is compatible with findings in psychology and other social sciences. Finally, their work has important implications for welfare economics and for government policy toward industry.

Download or read book The Oxford Handbook of Financial Regulation written by Niamh Moloney and published by OUP Oxford. This book was released on 2015-08-27 with total page 817 pages. Available in PDF, EPUB and Kindle. Book excerpt: The financial system and its regulation have undergone exponential growth and dramatic reform over the last thirty years. This period has witnessed major developments in the nature and intensity of financial markets, as well as repeated cycles of regulatory reform and development, often linked to crisis conditions. The recent financial crisis has led to unparalleled interest in financial regulation from policymakers, economists, legal practitioners, and the academic community, and has prompted large-scale regulatory reform. The Oxford Handbook of Financial Regulation is the first comprehensive, authoritative, and state of the art account of the nature of financial regulation. Written by an international team of leading scholars in the field, it takes a contextual and comparative approach to examine scholarly, policy, and regulatory developments in the past three decades. The first three parts of the Handbook address the underpinning horizontal themes which arise in financial regulation: financial systems and regulation; the organization of financial system regulation, including regional examples from the EU and the US; and the delivery of outcomes and regulatory techniques. The final three Parts address the perennial objectives of financial regulation, widely regarded as the anchors of financial regulation internationally: financial stability, market efficiency, integrity, and transparency; and consumer protection. The Oxford Handbook of Financial Regulation is an invaluable resource for scholars and students of financial regulation, economists, policy-makers and regulators.
Download or read book A Crisis of Beliefs written by Nicola Gennaioli and published by Princeton University Press. This book was released on 2018-09-11 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: How investor expectations move markets and the economy The collapse of Lehman Brothers in September 2008 caught markets and regulators by surprise. Although the government rushed to rescue other financial institutions from a similar fate after Lehman, it could not prevent the deepest recession in postwar history. A Crisis of Beliefs makes us rethink the financial crisis and the nature of economic risk. In this authoritative and comprehensive book, two of today’s most insightful economists reveal how our beliefs shape financial markets, lead to expansions of credit and leverage, and expose the economy to major risks. Nicola Gennaioli and Andrei Shleifer carefully walk readers through the unraveling of Lehman Brothers and the ensuing meltdown of the US financial system, and then present new evidence to illustrate the destabilizing role played by the beliefs of home buyers, investors, and regulators. Using the latest research in psychology and behavioral economics, they present a new theory of belief formation that explains why the financial crisis came as such a shock to so many people—and how financial and economic instability persist. A must-read for anyone seeking insights into financial markets, A Crisis of Beliefs shows how even the smartest market participants and regulators did not fully appreciate the extent of economic risk, and offers a new framework for understanding today’s unpredictable financial waters.

Download or read book The Evolution of Money written by David Orrell and published by Columbia University Press. This book was released on 2016-06-14 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Origins and Development of Financial Markets and Institutions written by Jeremy Atack and published by Cambridge University Press. This book was released on 2009-03-16 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collectively, mankind has never had it so good despite periodic economic crises of which the current sub-prime crisis is merely the latest example. Much of this success is attributable to the increasing efficiency of the world's financial institutions as finance has proved to be one of the most important causal factors in economic performance. In a series of insightful essays, financial and economic historians examine how financial innovations from the seventeenth century to the present have continually challenged established institutional arrangements, forcing change and adaptation by governments, financial intermediaries, and financial markets. Where these have been successful, wealth creation and growth have followed. When they failed, growth slowed and sometimes economic decline has followed. These essays illustrate the difficulties of co-ordinating financial innovations in order to sustain their benefits for the wider economy, a theme that will be of interest to policy makers as well as economic historians.

Download or read book Complexity and Evolution written by David S. Wilson and published by MIT Press. This book was released on 2016-08-19 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exploration of how approaches that draw on evolutionary theory and complexity science can advance our understanding of economics. Two widely heralded yet contested approaches to economics have emerged in recent years: one emphasizes evolutionary theory in terms of individuals and institutions; the other views economies as complex adaptive systems. In this book, leading scholars examine these two bodies of theory, exploring their possible impact on economics. Relevant concepts from evolutionary theory drawn on by the contributors include the distinction between proximate and ultimate causation, multilevel selection, cultural change as an evolutionary process, and human psychology as a product of gene-culture coevolution. Applicable ideas from complexity theory include self-organization, fractals, chaos theory, sensitive dependence, basins of attraction, and path dependence. The contributors discuss a synthesis of complexity and evolutionary approaches and the challenges that emerge. Focusing on evolutionary behavioral economics, and the evolution of institutions, they offer practical applications and point to avenues for future research.

Download or read book Modern Evolutionary Economics written by Richard R. Nelson and published by Cambridge University Press. This book was released on 2018-05-03 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary economics sees the economy as always in motion with change being driven largely by continuing innovation. This approach to economics, heavily influenced by the work of Joseph Schumpeter, saw a revival as an alternative way of thinking about economic advancement as a result of Richard Nelson and Sidney Winter's seminal book, An Evolutionary Theory of Economic Change, first published in 1982. In this long-awaited follow-up, Nelson is joined by leading figures in the field of evolutionary economics, reviewing in detail how this perspective has been manifest in various areas of economic inquiry where evolutionary economists have been active. Providing the perfect overview for interested economists and social scientists, readers will learn how in each of the diverse fields featured, evolutionary economics has enabled an improved understanding of how and why economic progress occurs.
