Book Description
We incorporate trading fees into a dynamic, multi-agent general-equilibrium model in which traders optimally decide when to trade. For that purpose, we propose an innovative algorithm that synchronizes the traders. Securities prices are not affected by the payment of the fees itself, but rather by the trade-off between smoothing consumption and smoothing holdings that the traders face. In calibrated examples, the interest rate and welfare decline, while risk premia and volatilities increase with trading fees. Liquidity risk and expected liquidity are priced, leading to deviations from the consumption-CAPM. With trading fees, capital is slow-moving which leads to slow price reversal.

Book Description
This paper develops and estimates a continuous-time model of a financial market where investors' trading strategies and the market maker's rule of price adjustments are best response to each other. There exists an equilibrium where the market maker finds it optimal to add volatility to the price s/he posts compared to the fundamental value of the asset. The model produces in a single and simple framework the two major findings of the empirical price-volume literature: serially correlated volatility and contemporaneous volume-volatility correlation. The fundamental price at every instant can be estimated based on the path of the actual market price, as well as transaction volume, up to that time. Nonlinear filters are derived to address the unobservability of the fundamental price.

Book Description
Chapter 1 studies how asset managers, due to reputation concerns, manipulate performance through taking latent risk dynamically. It is found that both skilled and unskilled managers load on excessive level of latent risk to boost performance even if investors are fully rational. The equilibrium risk taking by managers has interesting implications on investors' evaluation of manager's skill under normal market conditions and upon crash. Excessive risk taking reduces welfare of investor as well as unskilled managers, which calls for the presence of diligent third-party monitoring. Time required by investors to discover a manager's ability is also significantly lengthened. Our model yields several unique predictions about crash losses, which are supported by empirical analysis using hedge fund data. Besides, it provides complementary explanations for declining returns of large funds and the high demand for structured mortgage securities before the subprime mortgage crisis. Chapter 2 investigates price manipulation in general equilibrium with the only market imperfection being the presence of a non-competitive large trader. We propose the notion of "pure manipulation", in which the large trader manipulates security prices to improve-her welfare but supported by no genuine trading motive. The existence of pure manipulation is equivalent to the failure of the Weak Axiom of Revealed Preference of aggregate security demand at the competitive equilibrium. We state conditions that prohibit pure manipulation. We also demonstrate that heterogeneity in preferences and endowments, large trading needs and remaining insurance demand in the competitive equilibrium could lead to a jointly upward-sloping portfolio demand, which gives rise to pure manipulation that requires arbitrarily small capital commitment. In addition, we establish a link between static and multi-period manipulation and show that dynamic trading reduces manipulation power. Different security structures that complete the markets lead to different equilibrium allocations in the presence of a non-competitive trader. Chapter 3 analyzes how a risk-averse large institutional investor with price impact trades dynamically in the presence of momentum traders. The larger investor engages in several interesting manipulative behaviors. She may conduct "round-trip" trades to profit from momentum sentiment. She may buy (sell) before planned large sale(purchase) to manipulate intertemporal demand. In addition, she takes profit less aggressively to let the momentum sentiment last longer. Besides, with endogenously generated price impact, we find that higher price volatility does not lead to faster execution.

Book Description
An introduction to economic applications of the theory of continuous-time finance that strikes a balance between mathematical rigor and economic interpretation of financial market regularities. This book introduces the economic applications of the theory of continuous-time finance, with the goal of enabling the construction of realistic models, particularly those involving incomplete markets. Indeed, most recent applications of continuous-time finance aim to capture the imperfections and dysfunctions of financial markets—characteristics that became especially apparent during the market turmoil that started in 2008. The book begins by using discrete time to illustrate the basic mechanisms and introduce such notions as completeness, redundant pricing, and no arbitrage. It develops the continuous-time analog of those mechanisms and introduces the powerful tools of stochastic calculus. Going beyond other textbooks, the book then focuses on the study of markets in which some form of incompleteness, volatility, heterogeneity, friction, or behavioral subtlety arises. After presenting solutions methods for control problems and related partial differential equations, the text examines portfolio optimization and equilibrium in incomplete markets, interest rate and fixed-income modeling, and stochastic volatility. Finally, it presents models where investors form different beliefs or suffer frictions, form habits, or have recursive utilities, studying the effects not only on optimal portfolio choices but also on equilibrium, or the price of primitive securities. The book strikes a balance between mathematical rigor and the need for economic interpretation of financial market regularities, although with an emphasis on the latter.

Book Description
This paper develops and estimates a continuous-time model of a financial market where investors' trading strategies and the specialist's rule of price adjustments are the best response to each other. We examine how far modeling market microstructure in a purely rational framework can go in explaining alleged asset pricing ànomalies.' The model produces some major findings of the empirical literature: excess volatility of the market price compared to the asset's fundamental value, serially correlated volatility, contemporaneous volume-volatility correlation, and excess kurtosis of price changes. We implement a nonlinear filter to estimate the unobservable fundamental value, and avoid the discretization bias by computing the exact conditional moments of the price and volume processes over time intervals of any length.

Book Description
How to prevent runs on open-end mutual funds? In recent years, markets have observed an innovation that changed the way open-end funds are priced. Alternative pricing rules (known as swing pricing) adjust funds’ net asset values to pass on funds’ trading costs to transacting shareholders. Using unique data on investor transactions in U.K. corporate bond funds, we show that swing pricing eliminates the first-mover advantage arising from the traditional pricing rule and significantly reduces redemptions during stress periods. The positive impact of alternative pricing rules on fund flows reverses in calm periods when costs associated with higher tracking error dominate the pricing effect.

Book Description
During the first decade of the 21st century, the world has witnessed a plethora of corporate scandals, global economic crises, and rising environmental concerns. As a result of these developments, pressure has been mounting on businesses to pay more attention to the environmental and resource consequences of the products they produce and services they deliver. The Handbook of Research on Creating Sustainable Value in the Global Economy contains a collection of pioneering research on the integration of issues of sustainability within the traditional areas of management. While highlighting topics including green marketing, circular economy, and sustainable business, this book is ideally designed for managers, executives, environmentalists, economists, business professionals, researchers, academicians, and students in disciplines including marketing, economics, finance, operations management, communication science, and information technology.

Book Description
"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"--

Book Description
Academic finance has had a remarkable impact on many financial services. Yet long-term investors have received curiously little guidance from academic financial economists. Mean-variance analysis, developed almost fifty years ago, has provided a basic paradigm for portfolio choice. This approach usefully emphasizes the ability of diversification to reduce risk, but it ignores several critically important factors. Most notably, the analysis is static; it assumes that investors care only about risks to wealth one period ahead. However, many investors—-both individuals and institutions such as charitable foundations or universities—-seek to finance a stream of consumption over a long lifetime. In addition, mean-variance analysis treats financial wealth in isolation from income. Long-term investors typically receive a stream of income and use it, along with financial wealth, to support their consumption. At the theoretical level, it is well understood that the solution to a long-term portfolio choice problem can be very different from the solution to a short-term problem. Long-term investors care about intertemporal shocks to investment opportunities and labor income as well as shocks to wealth itself, and they may use financial assets to hedge their intertemporal risks. This should be important in practice because there is a great deal of empirical evidence that investment opportunities—-both interest rates and risk premia on bonds and stocks—-vary through time. Yet this insight has had little influence on investment practice because it is hard to solve for optimal portfolios in intertemporal models. This book seeks to develop the intertemporal approach into an empirical paradigm that can compete with the standard mean-variance analysis. The book shows that long-term inflation-indexed bonds are the riskless asset for long-term investors, it explains the conditions under which stocks are safer assets for long-term than for short-term investors, and it shows how labor income influences portfolio choice. These results shed new light on the rules of thumb used by financial planners. The book explains recent advances in both analytical and numerical methods, and shows how they can be used to understand the portfolio choice problems of long-term investors.
