Download or read book A Non Random Walk Down Wall Street written by Andrew W. Lo and published by Princeton University Press. This book was released on 2011-11-14 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over half a century, financial experts have regarded the movements of markets as a random walk--unpredictable meanderings akin to a drunkard's unsteady gait--and this hypothesis has become a cornerstone of modern financial economics and many investment strategies. Here Andrew W. Lo and A. Craig MacKinlay put the Random Walk Hypothesis to the test. In this volume, which elegantly integrates their most important articles, Lo and MacKinlay find that markets are not completely random after all, and that predictable components do exist in recent stock and bond returns. Their book provides a state-of-the-art account of the techniques for detecting predictabilities and evaluating their statistical and economic significance, and offers a tantalizing glimpse into the financial technologies of the future. The articles track the exciting course of Lo and MacKinlay's research on the predictability of stock prices from their early work on rejecting random walks in short-horizon returns to their analysis of long-term memory in stock market prices. A particular highlight is their now-famous inquiry into the pitfalls of "data-snooping biases" that have arisen from the widespread use of the same historical databases for discovering anomalies and developing seemingly profitable investment strategies. This book invites scholars to reconsider the Random Walk Hypothesis, and, by carefully documenting the presence of predictable components in the stock market, also directs investment professionals toward superior long-term investment returns through disciplined active investment management.
Download or read book Random Walk and the Heat Equation written by Gregory F. Lawler and published by American Mathematical Soc.. This book was released on 2010-11-22 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The heat equation can be derived by averaging over a very large number of particles. Traditionally, the resulting PDE is studied as a deterministic equation, an approach that has brought many significant results and a deep understanding of the equation and its solutions. By studying the heat equation and considering the individual random particles, however, one gains further intuition into the problem. While this is now standard for many researchers, this approach is generally not presented at the undergraduate level. In this book, Lawler introduces the heat equations and the closely related notion of harmonic functions from a probabilistic perspective. The theme of the first two chapters of the book is the relationship between random walks and the heat equation. This first chapter discusses the discrete case, random walk and the heat equation on the integer lattice; and the second chapter discusses the continuous case, Brownian motion and the usual heat equation. Relationships are shown between the two. For example, solving the heat equation in the discrete setting becomes a problem of diagonalization of symmetric matrices, which becomes a problem in Fourier series in the continuous case. Random walk and Brownian motion are introduced and developed from first principles. The latter two chapters discuss different topics: martingales and fractal dimension, with the chapters tied together by one example, a random Cantor set. The idea of this book is to merge probabilistic and deterministic approaches to heat flow. It is also intended as a bridge from undergraduate analysis to graduate and research perspectives. The book is suitable for advanced undergraduates, particularly those considering graduate work in mathematics or related areas.

Download or read book Brownian Motion written by Peter Mörters and published by Cambridge University Press. This book was released on 2010-03-25 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This eagerly awaited textbook covers everything the graduate student in probability wants to know about Brownian motion, as well as the latest research in the area. Starting with the construction of Brownian motion, the book then proceeds to sample path properties like continuity and nowhere differentiability. Notions of fractal dimension are introduced early and are used throughout the book to describe fine properties of Brownian paths. The relation of Brownian motion and random walk is explored from several viewpoints, including a development of the theory of Brownian local times from random walk embeddings. Stochastic integration is introduced as a tool and an accessible treatment of the potential theory of Brownian motion clears the path for an extensive treatment of intersections of Brownian paths. An investigation of exceptional points on the Brownian path and an appendix on SLE processes, by Oded Schramm and Wendelin Werner, lead directly to recent research themes.

Download or read book Wanderlust written by Rebecca Solnit and published by Penguin. This book was released on 2001-06-01 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: A passionate, thought-provoking exploration of walking as a political and cultural activity, from the author of Orwell's Roses Drawing together many histories--of anatomical evolution and city design, of treadmills and labyrinths, of walking clubs and sexual mores--Rebecca Solnit creates a fascinating portrait of the range of possibilities presented by walking. Arguing that the history of walking includes walking for pleasure as well as for political, aesthetic, and social meaning, Solnit focuses on the walkers whose everyday and extreme acts have shaped our culture, from philosophers to poets to mountaineers. She profiles some of the most significant walkers in history and fiction--from Wordsworth to Gary Snyder, from Jane Austen's Elizabeth Bennet to Andre Breton's Nadja--finding a profound relationship between walking and thinking and walking and culture. Solnit argues for the necessity of preserving the time and space in which to walk in our ever more car-dependent and accelerated world.

Available in PDF, EPUB and Kindle. Book excerpt: The #1 New York Times–bestselling author takes on subjects from banking to bitcoin: “Another winner from an A-list humorist.” ―Booklist Sharp-witted satirist and author of Parliament of Whores P. J. O’Rourke takes on his scariest subjects yet—business, investment, finance, and the political chicanery behind them. Want to get rich overnight for free in three easy steps with no risk? Then don’t buy this book. (Actually, if you believe there’s a book that can do that, you shouldn’t buy any books because you probably can’t read.) P. J. O’Rourke’s approach to business, investment, and finance is different. He takes the risks for you in his chapter “How I Learned Economics by Watching People Try to Kill Each Other.” He proposes “A Way to Raise Taxes That We’ll All Love”—a 200% tax on celebrities. He offers a brief history of economic transitions before exploring the world of high tech innovation with a chapter on “Unnovations,” which asks, “The Internet—whose idea was it to put all the idiots on earth in touch with each other?” He misunderstands bitcoin, which seems “like a weird scam invented by strange geeks with weaponized slide rules in the high school Evil Math Club.” And finally, he offers a fanciful short story about the morning that P. J. wakes up and finds that all the world’s goods and services are free! “The funniest writer in America.” ―The Wall Street Journal

Download or read book Road to Nowhere written by Paris Marx and published by Verso Books. This book was released on 2022-07-05 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: How to build a transportation system to provide mobility for all Road to Nowhere exposes the flaws in Silicon Valley’s vision of the future: ride-hailing services such as Uber and Lyft to take us anywhere; electric cars to make them ‘green’; and automation to ensure transport is cheap and ubiquitous. Such promises are implausible and potentially dangerous. As Paris Marx shows, these technological visions are a threat to our ideas of what a society should be. Electric cars are not a silver bullet for sustainability, and autonomous vehicles won’t guarantee road safety. There will not be underground tunnels to eliminate traffic congestion, and micromobility services will not replace car travel any sooner than we will see the arrival of the long-awaited flying car. In response, Marx offers a vision for a more collective way of organizing transportation systems that considers the needs of poor, marginalized, and vulnerable people. The book argues that rethinking mobility can be the first step in a broader reimagining of how we design and live in our future cities. We must create streets that allow for social interaction and conviviality. We need reasons to get out of our cars and to use public means of transit determined by community needs rather than algorithmic control. Such decisions should be guided by the search for quality of life rather than for profit.
