Available in PDF, EPUB and Kindle. Book excerpt: We study the effect of trading costs on information aggregation and acquisition in financial markets. For a given precision of investors' private information, an irrelevance result emerges when investors are ex-ante identical: price informativeness is independent of the level of trading costs. When investors are ex-ante heterogeneous, anything goes, and a change in trading costs can increase or decrease price informativeness, depending on the source of heterogeneity. Our results are valid under quadratic, linear, and fixed costs. Through a reduction in information acquisition, trading costs reduce price informativeness. We discuss how our results inform the policy debate on financial transaction taxes/Tobin taxes.

Available in PDF, EPUB and Kindle. Book excerpt: We study the effect of trading costs on information aggregation and information acquisition in financial markets. For a given precision of investors' private information, an irrelevance result emerges when investors are ex-ante identical: price informativeness does not depend on the level of trading costs. This result holds independently of whether trading costs are quadratic or linear, investors behave competitively or strategically, and applies to both static and dynamic economies. When investors are ex-ante heterogeneous, trading costs reduce (increase) price informativeness if and only if investors who disproportionately trade on information are more (less) elastic than investors who mostly trade due to hedging. Trading costs always reduce information acquisition and consequently price informativeness, even when price informativeness remains unchanged for a given amount of information. Our results matter to understand the consequences of cheaper financial trading and the effects of financial transaction taxes.

Download or read book Information Efficiency in Financial and Betting Markets written by Leighton Vaughan Williams and published by Cambridge University Press. This book was released on 2005-09-29 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The degree to which markets incorporate information is one of the most important questions facing economists today. This book provides a fascinating study of the existence and extent of information efficiency in financial markets, with a special focus on betting markets. Betting markets are selected for study because they incorporate features highly appropriate to a study of information efficiency, in particular the fact that each bet has a well-defined end point at which its value becomes certain. Using international examples, this book reviews and analyses the issue of information efficiency in both financial and betting markets. Part I is an extensive survey of the existing literature, while Part II presents a range of readings by leading academics. Insights gained from the book will interest students of financial economics, financial market analysts, mathematicians and statisticians, and all those with a special interest in finance or gambling.

Download or read book Information Efficiency and Anomalies in Asian Equity Markets written by Qaiser Munir and published by Routledge. This book was released on 2016-10-04 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficient market hypothesis (EMH) maintains that all relevant information is fully and immediately reflected in stock prices and that investors will obtain an equilibrium rate of return. The EMH has far reaching implications for capital allocation, stock price prediction, and the effectiveness of specific trading strategies. Equity market anomalies reflect that the market is inefficient and hence, contradicts the EMH. This book gathers both theoretical and practical perspectives, by including research issues, methodological approaches, practical case studies, uses of new policy and other points of view related to equity market efficiency to help address the future challenges facing the global equity markets and economies. Information Efficiency and Anomalies in Asian Equity Markets: Theories and evidence is an insightful resource that will be useful for students, academics and professionals alike.

Download or read book Market Structure Informational Efficiency and Liquidity written by Erik Theissen and published by . This book was released on 1998 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports the results of 18 market experiments that were conducted in order to compare the call market, the continuous auction and the dealer market. The design incorporates asymmetric information but guarantees that the ex-ante quality of the private signals of all traders is identical. Therefore, the aggregation of diverse information can be analyzed in the absence of insider trading. Single transaction prices in the call and continuous auction market are found to be much more efficient than prices in the dealer market. The latter is, however, very efficient when average prices are analyzed. Averaging the prices of a trading period largely eliminates the bid-ask spread. The conclusion is therefore that prices in a dealer market convey high quality information, but at the expense of high transaction costs. The call market, although exhibiting small pricing errors, shows a systematic tendency towards underadjustment to new information. An analysis of market liquidity using various measures proposed in the literature shows that execution costs are lowest in the call market and highest in the dealer market. The analysis also reveals that both the trading volume and Roll's (1984) serial covariance estimator are inappropriate measures of execution costs in the present context. The quality of the private signals traders receive influences portfolio structure but does not influence end-of-period wealth. This result is consistent with efficient price discovery in the experimental markets.

This book was released on 1989 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this work is to provide a critical presentation and some extensions of two perspectives of informational efficiency: On the one hand the neoclassical perspective or «arithmomorphic approach» explains efficiency in terms of a concept mainly based on an explicit economic theory. On the other hand, in the Austrian perspective or «causal genetic approach» attention is drawn to the entrepreneurial element of human decision making related to an arbitrage theory of profit which is not traced back to anonymous market forces but rather to incessant discovery of information guided by entrepreneurial alertness.

Download or read book Introduction to the Economics of Financial Markets written by James Bradfield and published by OUP USA. This book was released on 2007-02-08 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many textbooks for business students that provide a systematic, introductory development of the economics of financial markets. However, there are as yet no introductory textbooks aimed at more easily daunted undergraduate liberal arts students. Introduction to the Economics of Financial Markets fills this gap by providing an extremely accessible introductory exposition of how economists analyze both how, and how well, financial markets organize the intertemporal allocation of scarce resources. The central theme is that the function of a system of financial markets is to enable consumers, investors, and managers of firms to effect mutually beneficial intertemporal exchanges. James Bradfield uses the standard concept of economic efficiency (Pareto Optimality) to assess the efficacy of the financial markets. He presents an intuitive, and introductory, understanding of the primary theoretical and empirical models that economists use to analyze financial markets, and then uses these models to discuss implications for public policy. Students who use this text will acquire an understanding of the economics of financial markets that will enable them to read, with some sophistication, articles in the public press about financial markets and about public policy toward those markets. The book is addressed to undergraduate students in the liberal arts, but will also be useful for undergraduate and beginning graduate students in programs of business administration who want an understanding of how economists assess financial markets against the criteria of allocative and informational efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book addresses four standard business school subjects: microeconomics, macroeconomics, finance and information systems as they relate to trading, liquidity, and market structure. It provides a detailed examination of the impact of trading costs and other impediments of trading that the authors call rictions It also presents an interactive simulation model of equity market trading, TraderEx, that enables students to implement trading decisions in different market scenarios and structures. Addressing these topics shines a bright light on how a real-world financial market operates, and the simulation provides students with an experiential learning opportunity that is informative and fun. Each of the chapters is designed so that it can be used as a stand-alone module in an existing economics, finance, or information science course. Instructor resources such as discussion questions, Powerpoint slides and TraderEx exercises are available online.

Download or read book Have Financial Markets Become More Informative written by Jennie Bai and published by . This book was released on 2012-12-01 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The finance industry has grown, financial markets have become more liquid, and information technology allows arbitrageurs to trade faster than ever. But have market prices then become more informative? We use stock and bond prices to forecast earnings and find that the information content of market prices has not improved since 1960. We use a model with information acquisition and investment to link financial development, price informativeness, and allocational efficiency. As information costs fall, the predictable component of future earnings should rise and hence improve capital allocation and welfare. We find that this component has remained stable over the past 50 years. When we decompose price informativeness into real price efficiency and forecasting price efficiency, we find that both have remained stable.

Download or read book Trading Frequency and Information Efficiency written by Feng Gao and published by . This book was released on 2014 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper analyzes the relation between price informativeness and trading frequency. We develop a sequential trading model to capture the tradeoff between trading more frequently and acquiring more information. The key component of the model is the cost of information collection and processing. When information flow comes sequentially, traders must give up some early trading opportunities if they want to acquire more information. We show that more trading opportunities may induce informed traders to participate in more trades before obtaining more accurate information. Consequently, when informed traders trade more frequently, less information is impounded into prices. Empirical tests using stocks listed on NYSE, as well as the Shanghai Stock Exchange and the Shenzhen Stock Exchange, support the two testable implications of our model -- a negative relation between the quality of the information environment and informed traders' trading frequency, and a negative relation between informed traders' trading frequency and price informativeness. One implication of our model and empirical results is that a decrease in excessive trading activities may help shift market participants' attention from short-term price movements to companies' fundamental information so that the information could be more efficiently impounded into prices, which, in turn, may further lead toward better resource allocation in financial markets.

Download or read book Market Microstructure in Emerging and Developed Markets written by H. Kent Baker and published by Wiley. This book was released on 2013-08-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive guide to the dynamic area of finance known as market microstructure Interest in market microstructure has grown dramatically in recent years due largely in part to the rapid transformation of the financial market environment by technology, regulation, and globalization. Looking at market transactions at the most granular level—and taking into account market structure, price discovery, information flows, transaction costs, and the trading process—market microstructure also forms the basis of high-frequency trading strategies that can help professional investors generate profits and/or execute optimal transactions. Part of the Robert W. Kolb Series in Finance, Market Microstructure skillfully puts this discipline in perspective and examines how the working processes of markets impact transaction costs, prices, quotes, volume, and trading behavior. Along the way, it offers valuable insights on how specific features of the trading process like the existence of intermediaries or the environment in which trading takes place affect the price formation process. Explore issues including market structure and design, transaction costs, information flows, and disclosure Addresses market microstructure in emerging markets Covers the legal and regulatory issues impacting this area of finance Contains contributions from both experienced financial professionals and respected academics in this field If you're looking to gain a firm understanding of market microstructure, this book is the best place to start.

Download or read book Decimal Pricing and Information Based Trading written by Xin Zhao and published by . This book was released on 2006 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study we analyze the effect of tick size on information-based trading. Although prior studies provide extensive evidence on the effect of tick size on market quality measures such as spreads, depths, and return volatility, there is little evidence as to the effect of tick size on the informational efficiency of asset price. Our results indicate that the probability of information-based trading during the post-decimal period is significantly greater than the corresponding figure during the pre-decimal period. We also show that the increase in information-based trading after decimalization cannot be attributed to concurrent changes in stock attributes. We interpret our findings as evidence that the smaller tick size under penny pricing encourages information-based trading and thereby raises the informational efficiency of asset price.
