Application of the Concept of Dissonance to Explain the Phenomenon of Return-Volatility Relationship


Book Description

In this paper, we attempt to provide a behavioral explanation to the observed asymmetric return-volatility relationship. In some cases, the affect heuristic, mental accounting and extrapolation bias may not be adequate to explain returnvolatility dynamics. We build up three hypotheses to establish whether return-volatility relationship is influenced by cognitive dissonance. We observe that both positive and negative relationships exist for return-volatility dynamics. We show that cognitive dissonance is responsible for return-volatility relationship and which can explain their observed negative and positive relationships. Our third hypothesis relates to significance of volatility feedback theory. We find that it is rejected, which confirms that volatility feedback theory is not always tenable for explaining asymmetric return-volatility relationship.

Inefficient Markets


Book Description

The efficient markets hypothesis has been the central proposition in finance for nearly thirty years. It states that securities prices in financial markets must equal fundamental values, either because all investors are rational or because arbitrage eliminates pricing anomalies. This book describes an alternative approach to the study of financial markets: behavioral finance. This approach starts with an observation that the assumptions of investor rationality and perfect arbitrage are overwhelmingly contradicted by both psychological and institutional evidence. In actual financial markets, less than fully rational investors trade against arbitrageurs whose resources are limited by risk aversion, short horizons, and agency problems. The book presents and empirically evaluates models of such inefficient markets. Behavioral finance models both explain the available financial data better than does the efficient markets hypothesis and generate new empirical predictions. These models can account for such anomalies as the superior performance of value stocks, the closed end fund puzzle, the high returns on stocks included in market indices, the persistence of stock price bubbles, and even the collapse of several well-known hedge funds in 1998. By summarizing and expanding the research in behavioral finance, the book builds a new theoretical and empirical foundation for the economic analysis of real-world markets.




Cognitive Dissonance


Book Description

Capital as Power


Book Description

Conventional theories of capitalism are mired in a deep crisis: after centuries of debate, they are still unable to tell us what capital is. Liberals and Marxists both think of capital as an ‘economic’ entity that they count in universal units of ‘utils’ or ‘abstract labour’, respectively. But these units are totally fictitious. Nobody has ever been able to observe or measure them, and for a good reason: they don’t exist. Since liberalism and Marxism depend on these non-existing units, their theories hang in suspension. They cannot explain the process that matters most – the accumulation of capital. This book offers a radical alternative. According to the authors, capital is not a narrow economic entity, but a symbolic quantification of power. It has little to do with utility or abstract labour, and it extends far beyond machines and production lines. Capital, the authors claim, represents the organized power of dominant capital groups to reshape – or creorder – their society. Written in simple language, accessible to lay readers and experts alike, the book develops a novel political economy. It takes the reader through the history, assumptions and limitations of mainstream economics and its associated theories of politics. It examines the evolution of Marxist thinking on accumulation and the state. And it articulates an innovative theory of ‘capital as power’ and a new history of the ‘capitalist mode of power’.

Long/Short Market Dynamics


Book Description

Hedge funds are now the largest volume players in the capital markets. They follow a wide assortment of strategies but their activities have replaced and overshadowed the traditional model of the long only portfolio manager. Many of the traditional technical indicators and commonly accepted trading strategies have become obsolete or ineffective. The focus throughout the book is to describe the principal innovations that have been made within the equity markets over the last several years and that have changed the ground rules for trading activities. By understanding these changes the active trader is far better equipped to profit in today’s more complex and risky markets. Long/Short Market Dynamics includes: A completely new technique, Comparative Quantiles Analysis, for identifying market turning points is introduced. It is based on statistical techniques that can be used to recognize money flow and price/momentum divergences that can provide substantial profit opportunities. Power laws, regime shifts, self-organized criticality, phase transitions, network dynamics, econophysics, algorithmic trading and other ideas from the science of complexity are examined. All are described as concretely as possible and avoiding unnecessary mathematics and formalism. Alpha generation, portfolio construction, hedge ratios, and beta neutral portfolios are illustrated with case studies and worked examples. Episodes of financial contagion are illustrated with a proposed explanation of their origins within underlying market dynamics




Freefall: America, Free Markets, and the Sinking of the World Economy


Book Description

An incisive look at the global economic crisis, our flawed response, and the implications for the world’s future prosperity. The Great Recession, as it has come to be called, has impacted more people worldwide than any crisis since the Great Depression. Flawed government policy and unscrupulous personal and corporate behavior in the United States created the current financial meltdown, which was exported across the globe with devastating consequences. The crisis has sparked an essential debate about America’s economic missteps, the soundness of this country’s economy, and even the appropriate shape of a capitalist system. Few are more qualified to comment during this turbulent time than Joseph E. Stiglitz. Winner of the 2001 Nobel Prize in Economics, Stiglitz is “an insanely great economist, in ways you can’t really appreciate unless you’re deep into the field” (Paul Krugman, New York Times). In Freefall, Stiglitz traces the origins of the Great Recession, eschewing easy answers and demolishing the contention that America needs more billion-dollar bailouts and free passes to those “too big to fail,” while also outlining the alternatives and revealing that even now there are choices ahead that can make a difference. The system is broken, and we can only fix it by examining the underlying theories that have led us into this new “bubble capitalism.” Ranging across a host of topics that bear on the crisis, Stiglitz argues convincingly for a restoration of the balance between government and markets. America as a nation faces huge challenges—in health care, energy, the environment, education, and manufacturing—and Stiglitz penetratingly addresses each in light of the newly emerging global economic order. An ongoing war of ideas over the most effective type of capitalist system, as well as a rebalancing of global economic power, is shaping that order. The battle may finally give the lie to theories of a “rational” market or to the view that America’s global economic dominance is inevitable and unassailable. For anyone watching with indignation while a reckless Wall Street destroyed homes, educations, and jobs; while the government took half-steps hoping for a “just-enough” recovery; and while bankers fell all over themselves claiming not to have seen what was coming, then sought government bailouts while resisting regulation that would make future crises less likely, Freefall offers a clear accounting of why so many Americans feel disillusioned today and how we can realize a prosperous economy and a moral society for the future.




Folk Devils and Moral Panics


Book Description

'Richly documented and convincingly presented' -- New Society Mods and Rockers, skinheads, video nasties, designer drugs, bogus asylum seeks and hoodies. Every era has its own moral panics. It was Stanley Cohen's classic account, first published in the early 1970s and regularly revised, that brought the term 'moral panic' into widespread discussion. It is an outstanding investigation of the way in which the media and often those in a position of political power define a condition, or group, as a threat to societal values and interests. Fanned by screaming media headlines, Cohen brilliantly demonstrates how this leads to such groups being marginalised and vilified in the popular imagination, inhibiting rational debate about solutions to the social problems such groups represent. Furthermore, he argues that moral panics go even further by identifying the very fault lines of power in society. Full of sharp insight and analysis, Folk Devils and Moral Panics is essential reading for anyone wanting to understand this powerful and enduring phenomenon. Professor Stanley Cohen is Emeritus Professor of Sociology at the London School of Economics. He received the Sellin-Glueck Award of the American Society of Criminology (1985) and is on the Board of the International Council on Human Rights. He is a member of the British Academy.
