High-Frequency Financial Econometrics


Book Description

A comprehensive introduction to the statistical and econometric methods for analyzing high-frequency financial data High-frequency trading is an algorithm-based computerized trading practice that allows firms to trade stocks in milliseconds. Over the last fifteen years, the use of statistical and econometric methods for analyzing high-frequency financial data has grown exponentially. This growth has been driven by the increasing availability of such data, the technological advancements that make high-frequency trading strategies possible, and the need of practitioners to analyze these data. This comprehensive book introduces readers to these emerging methods and tools of analysis. Yacine Aït-Sahalia and Jean Jacod cover the mathematical foundations of stochastic processes, describe the primary characteristics of high-frequency financial data, and present the asymptotic concepts that their analysis relies on. Aït-Sahalia and Jacod also deal with estimation of the volatility portion of the model, including methods that are robust to market microstructure noise, and address estimation and testing questions involving the jump part of the model. As they demonstrate, the practical importance and relevance of jumps in financial data are universally recognized, but only recently have econometric methods become available to rigorously analyze jump processes. Aït-Sahalia and Jacod approach high-frequency econometrics with a distinct focus on the financial side of matters while maintaining technical rigor, which makes this book invaluable to researchers and practitioners alike.




Computer-mediated Communication


Book Description

Text-based interaction among humans connected via computer networks, such as takes place via email and in synchronous modes such as “chat”, MUDs and MOOs, has attracted considerable popular and scholarly attention. This collection of 14 articles on text-based computer-mediated communication (CMC), is the first to bring empirical evidence from a variety of disciplinary perspectives to bear on questions raised by the new medium. The first section, linguistic perspectives, addresses the question of how CMC compares with speaking and writing, and describes its unique structural characteristics. Section two, on social and ethical perspectives, explores conflicts between the interests of groups and those of individual users, including issues of online sex and sexism. In the third section, cross-cultural perspectives, the advantages and risks of using CMC to communicate across cultures are examined in three studies involving users in East Asia, Mexico, and students of ethnically diverse backgrounds in remedial writing classes in the United States. The final section deals with the effects of CMC on group interaction: in a women's studies mailing list, a hierarchically-organized workplace, and a public protest on the Internet against corporate interests.

Discretization of Processes


Book Description

In applications, and especially in mathematical finance, random time-dependent events are often modeled as stochastic processes. Assumptions are made about the structure of such processes, and serious researchers will want to justify those assumptions through the use of data. As statisticians are wont to say, “In God we trust; all others must bring data.” This book establishes the theory of how to go about estimating not just scalar parameters about a proposed model, but also the underlying structure of the model itself. Classic statistical tools are used: the law of large numbers, and the central limit theorem. Researchers have recently developed creative and original methods to use these tools in sophisticated (but highly technical) ways to reveal new details about the underlying structure. For the first time in book form, the authors present these latest techniques, based on research from the last 10 years. They include new findings. This book will be of special interest to researchers, combining the theory of mathematical finance with its investigation using market data, and it will also prove to be useful in a broad range of applications, such as to mathematical biology, chemical engineering, and physics.







The Elements of Financial Econometrics


Book Description

A compact, master's-level textbook on financial econometrics, focusing on methodology and including real financial data illustrations throughout. The mathematical level is purposely kept moderate, allowing the power of the quantitative methods to be understood without too much technical detail.
