Available in PDF, EPUB and Kindle. Book excerpt: We extend Kyle's (1985) model of insider trading to the case where liquidity provided by noise traders follows a general stochastic process. Even though the level of noise trading volatility is observable, in equilibrium, measured price impact is stochastic. If noise trading volatility is mean-reverting, then the equilibrium price follows a multivariate 'stochastic bridge' process, which displays stochastic volatility. This is because insiders choose to optimally wait to trade more aggressively when noise trading activity is higher. In equilibrium, market makers anticipate this, and adjust prices accordingly. More private information is revealed when volatility is higher. In time series, insiders trade more aggressively, when measured price impact is lower. Therefore, execution costs to uninformed traders can be higher when price impact is lower.

Available in PDF, EPUB and Kindle. Book excerpt: The Kyle-Back model for insider trading describes how insiders behave in the presence of access to privileged information. We introduce stochastic liquidity into the Kyle-Back model, allowing for times of high and low volatility like in real markets and construct and prove an equilibrium in this environment. The key insight of this work is that in the equilibrium, the price is set not based on order flow directly, but an adjusted version of such which weights trades based on the liquidity at the time of transaction. The work is extension of \\\\cite{CDF}, which considered and answered the same extension but only in the special case of a normally distributed final asset price. We find in particular with a log-normal price distribution that the log-return up to maturity at is Gaussian for any given scenario of noise-trading volatility even though the price process itself has stochastic volatility.

Book excerpt: The continuous-time version of Kyle's (1985) model of asset pricing with asymmetric information is studied, and generalized in various directions, i.e., by allowing time-varying liquidity trading, and by having weaker a priori assumptions on the model. This extension is made possible by the use of filtering theory. We derive the optimal trade for an insider and the corresponding price of the risky asset; the insider's trading intensity satisfies a deterministic integral equation, given perfect inside information.

Available in PDF, EPUB and Kindle. Book excerpt: We compare competitive equilibrium outcomes with and without trading by an informed insider, in a model with ex ante aggregate investment choices which can not respond to any enhanced informational content of interim asset prices associated with insider trading. Noise trading is generated by aggregate uncertainty regarding other agents' intertemporal consumption preferences. Since all agents, and noise traders in particular, have well-specified preferences, the welfare implications of insider trading for outsiders can be analyzed. Moreover, the allocation without the insider trading is not assumed to be ex ante (constrained) Pareto efficient, since we depart from the standard setup with negative exponential utility and normal returns. Our welfare analysis uncovers the potentially beneficial role of interim information revelation arising from insider trading, in improving the risk-sharing among outsiders with stochastic liquidity needs.

Book excerpt: The continuous-time version of Kyle's (1985) model of asset pricing with asymmetric information is studied, and generalized in various directions, i.e., by allowing time-varying noise trading, and by allowing the orders of the noise traders to be correlated with the insider's signal. From rather simple assumptions we are able to derive the optimal trade for an insider; the trading intensity satisfies a deterministic integral equation, given perfect inside information. We use a new technique called forward integration in order to find the optimal trading strategy. This is an extension of the stochastic integral which takes account of the informational asymmetry inherent in this problem. The market makers' price response is found by the use of filtering theory. The novelty is our approach, which could be extended in scope.

Available in PDF, EPUB and Kindle. Book excerpt: This paper studies a model of strategic trading with asymmetric information of an asset whose value follows a Brownian motion. An insider continuously observes a signal that tracks the evolution of the asset fundamental value. At a random time a public announcement reveals the current value of the asset to all the traders. The equilibrium has two regimes separated by an endogenously determined time T. In [0,T), the insider gradually transfers her information to the market and the market's uncertainty about the value of the asset decreases monotonically. By time T all her information is transferred to the market and the price agrees with the market value of the asset. After T, the insider trades large volumes and reveals her information immediately, so market prices track the market value perfectly. Despite this market efficiency, the insider is able to collect strictly positive rents after T.

Available in PDF, EPUB and Kindle. Book excerpt: This book undertakes a detailed construction of Dynamic Markov Bridges using a combination of theory and real-world applications to drive home important concepts and methodologies. In Part I, theory is developed using tools from stochastic filtering, partial differential equations, Markov processes, and their interplay. Part II is devoted to the applications of the theory developed in Part I to asymmetric information models among financial agents, which include a strategic risk-neutral insider who possesses a private signal concerning the future value of the traded asset, non-strategic noise traders, and competitive risk-neutral market makers. A thorough analysis of optimality conditions for risk-neutral insiders is provided and the implications on equilibrium of non-Gaussian extensions are discussed. A Markov bridge, first considered by Paul Lévy in the context of Brownian motion, is a mathematical system that undergoes changes in value from one state to another when the initial and final states are fixed. Markov bridges have many applications as stochastic models of real-world processes, especially within the areas of Economics and Finance. The construction of a Dynamic Markov Bridge, a useful extension of Markov bridge theory, addresses several important questions concerning how financial markets function, among them: how the presence of an insider trader impacts market efficiency; how insider trading on financial markets can be detected; how information assimilates in market prices; and the optimal pricing policy of a particular market maker. Principles in this book will appeal to probabilists, statisticians, economists, researchers, and graduate students interested in Markov bridges and market microstructure theory.

This book was released on 2023-04-30 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leveraging the research efforts of more than sixty experts in the area, this book reviews cutting-edge practices in machine learning for financial markets. Instead of seeing machine learning as a new field, the authors explore the connection between knowledge developed by quantitative finance over the past forty years and techniques generated by the current revolution driven by data sciences and artificial intelligence. The text is structured around three main areas: 'Interactions with investors and asset owners,' which covers robo-advisors and price formation; 'Risk intermediation,' which discusses derivative hedging, portfolio construction, and machine learning for dynamic optimization; and 'Connections with the real economy,' which explores nowcasting, alternative data, and ethics of algorithms. Accessible to a wide audience, this invaluable resource will allow practitioners to include machine learning driven techniques in their day-to-day quantitative practices, while students will build intuition and come to appreciate the technical tools and motivation for the theory.

Available in PDF, EPUB and Kindle. Book excerpt: Today all would agree that Mexico and the United States have never been closer--that the fates of the two republics are intertwined. Mexico has become an intimate part of life in almost every community in the United States, through immigration, imported produce, business ties, or illegal drugs. It is less a neighbor than a sibling; no matter what our differences, it is intricately a part of our existence. In the fully updated second edition of Mexico: What Everyone Needs to Know(R), Roderic Ai Camp gives readers the most essential information about our sister republic to the south. Camp organizes chapters around major themes--security and violence, economic development, foreign relations, the colonial heritage, and more. He asks questions that take us beyond the headlines: Why does Mexico have so much drug violence? What was the impact of the North American Free Trade Agreement? How democratic is Mexico? Who were Benito Juarez and Pancho Villa? What is the PRI (the Institutional Revolutionary Party)? The answers are sometimes surprising. Despite ratification of NAFTA, for example, Mexico has fallen behind Brazil and Chile in economic growth and rates of poverty. Camp explains that lack of labor flexibility, along with low levels of transparency and high levels of corruption, make Mexico less competitive than some other Latin American countries. The drug trade, of course, enhances corruption and feeds on poverty; approximately 450,000 Mexicans now work in this sector. Brisk, clear, and informed, Mexico: What Everyone Needs To Know(R) offers a valuable primer for anyone interested in the past, present, and future of our neighbor to the South. Links to video interviews with prominent Mexicans appear throughout the text.

Download or read book Inside and Outside Liquidity written by Bengt Holmstrom and published by MIT Press. This book was released on 2013-01-11 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two leading economists develop a theory explaining the demand for and supply of liquid assets. Why do financial institutions, industrial companies, and households hold low-yielding money balances, Treasury bills, and other liquid assets? When and to what extent can the state and international financial markets make up for a shortage of liquid assets, allowing agents to save and share risk more effectively? These questions are at the center of all financial crises, including the current global one. In Inside and Outside Liquidity, leading economists Bengt Holmström and Jean Tirole offer an original, unified perspective on these questions. In a slight, but important, departure from the standard theory of finance, they show how imperfect pledgeability of corporate income leads to a demand for as well as a shortage of liquidity with interesting implications for the pricing of assets, investment decisions, and liquidity management. The government has an active role to play in improving risk-sharing between consumers with limited commitment power and firms dealing with the high costs of potential liquidity shortages. In this perspective, private risk-sharing is always imperfect and may lead to financial crises that can be alleviated through government interventions.

Download or read book Market Liquidity written by Thierry Foucault and published by Oxford University Press. This book was released on 2023 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The process by which securities are traded is very different from the idealized picture of a frictionless and self-equilibrating market offered by the typical finance textbook. This book offers a more accurate and authoritative take on this process. The book starts from the assumption that not everyone is present at all times simultaneously on the market, and that participants have quite diverse information about the security's fundamentals. As a result, the order flow is a complex mix of information and noise, and a consensus price only emerges gradually over time as the trading process evolves and the participants interpret the actions of other traders. Thus, a security's actual transaction price may deviate from its fundamental value, as it would be assessed by a fully informed set of investors. The book takes these deviations seriously, and explains why and how they emerge in the trading process and are eventually eliminated. The authors draw on a vast body of theoretical insights and empirical findings on security price formation that have come to form a well-defined field within financial economics known as "market microstructure." Focusing on liquidity and price discovery, the book analyzes the tension between the two, pointing out that when price-relevant information reaches the market through trading pressure rather than through a public announcement, liquidity may suffer. It also confronts many striking phenomena in securities markets and uses the analytical tools and empirical methods of market microstructure to understand them. These include issues such as why liquidity changes over time and differs across securities, why large trades move prices up or down, and why these price changes are subsequently reversed, and why we observe temporary deviations from asset fair values"--
