Available in PDF, EPUB and Kindle. Book excerpt: The first chapter of this dissertation explores the effects of the recent rise of passive investing on the U.S. stock market. The analysis establishes a strong relation between passive investment and aggregate price dynamics such as systematic volatility, idiosyncratic volatility, and price synchronicity, suggesting that investors should consider trading activity of passive products in decision making. The second chapter examines the pricing of characteristics and betas in the cross-section of expected corporate loan returns. Despite the increasing popularity of the secondary loan market among institutional investors, this market is unexplored in the context of empirical asset pricing literature. This comprehensive study takes the first step to fill the gap by investigating the sources of risk and predictability of corporate loan returns. We find that one loan specific characteristic, momentum, and one covariance-based characteristic, default beta, explain the cross-section of loan expected returns. The final chapter first introduces a measure of model uncertainty regarding the future return distribution of the U.S. stock market and then examines the pricing of model uncertainty in the cross-section of stock returns.

This book was released on 2022-11-22 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book adds to the resolution of two problems in finance and economics: i) what is macro-financial uncertainty? : How to measure it? How is it different from risk? How important is it for the financial markets? And ii) what sort of asymmetries underlie financial risk and uncertainty propagation across the global financial markets? That is, how risk and uncertainty change according to factors such as market states or market participants. In Chapter 2, which is entitled “Momentum Uncertainties”, the relationship between macroeconomic uncertainty and the abnormal returns of a momentum trading strategy in the stock market is studies. We show that high levels of uncertainty in the economy impact negatively and significantly the returns of a portfolio of stocks that consist of buying past winners and selling past losers. High uncertainty reduces below zero the abnormal returns of momentum, extinguishes the Sharpe ratio of the momentum strategy, while increases the probability of momentum crashes both by increasing the skewness and the kurtosis of the momentum return distribution. Uncertainty acts as an economic regime that underlies abrupt changes over time of the returns generated by momentum strategies. In Chapter 3, “Measuring Uncertainty in the Stock Market”, a new index for measuring stock market uncertainty on a daily basis is proposed. The index considers the inherent differentiation between uncertainty and the common variations between the series. The second contribution of chapter 3 is to show how this financial uncertainty index can also serve as an indicator of macroeconomic uncertainty. Finally, the dynamic relationship between uncertainty and the series of consumption, interest rates, production and stock market prices, among others, is analized. In chapter 4: “Uncertainty, Systemic Shocks and the Global Banking Sector: Has the Crisis Modified their Relationship?” we explore the stability of systemic risk and uncertainty propagation among financial institutions in the global economy, and show that it has remained stable over the last decade. Additionally, a new simple tool for measuring the resilience of financial institutions to these systemic shocks is provided. We examine the characteristics and stability of systemic risk and uncertainty, in relation to the dynamics of the banking sector stock returns. This sort of evidence is supportive of past claims, made in the field of macroeconomics, which hold that during the global financial crisis the financial system may have faced stronger versions of traditional shocks rather than a new type of shock. In chapter 5, “Currency downside risk, liquidity, and financial stability”, downside risk propagation across global currency markets and the ways in which it is related to liquidity is analyzed. Two primary contributions to the literature follow. First, tail-spillovers between currencies in the global FX market are estimated. This index is easy to build and does not require intraday data, which constitutes an important advantage. Second, we show that turnover is related to risk spillovers in global currency markets. Chapter 6 is entitled “Spillovers from the United States to Latin American and G7 Stock Markets: A VAR-Quantile Analysis”. This chapter contributes to the studies of contagion, market integration and cross-border spillovers during both regular and crisis episodes by carrying out a multivariate quantile analysis. It focuses on Latin American stock markets, which have been characterized by a highly positive dynamic in recent decades, in terms of market capitalization and liquidity ratios, after a far-reaching process of market liberalization and reforms to pension funds across the continent during the 80s and 90s. We document smaller dependences between the LA markets and the US market than those between the US and the developed economies, especially in the highest and lowest quantiles.

Download or read book Three Essays on Idiosyncratic Volatility written by Anas Aboulamer and published by . This book was released on 2015 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of three essays. The first essay (chapter two) examines the relationship between idiosyncratic volatility and future returns in the Canadian market. The negative relationship between realized idiosyncratic volatility (RIvol) and future returns uncovered by Ang et al. (2006) for the US market has been attributed to return reversals. For the Canadian market where return reversals have considerably less importance, we find that RIvol is positively related to future returns, even after controlling for risk loadings, illiquidity and reversals. Unlike the findings of Bali et al. (2011) for the US market, we find for the Canadian market that the relationship between extreme positive returns and future returns is positive and that idiosyncratic volatility is consistently positively related to future returns. The second essay (chapter three) discusses the relationship between closed end fund discounts and the level of uncertainty about its holdings. Our trade-off model states that the intrinsic premium of a closed-end fund (CEF) is equal to the CEF’s price minus both its NAVPS (net asset value per share) and the net present value (NPV) of its future benefits from liquidity, managerial abilities and leverage minus its managerial costs. Any additional premium will persist to the extent that arbitrage between these two price series is both costly and risky. We find that arbitrage incompleteness due to the uncertainties about this NPV and the CEF’s holdings, as captured by idiosyncratic risk and other proxies, explains over two-thirds of the variation in CEF premiums or their changes. As expected, we find that the CEF premium is negatively related to gross leverage, management fees, cash and bond holdings, and positively related to liquidity enhancement, CEF performance and net leverage. These results are consistent with our finding that changes in CEF prices and NAVPS are more integrated than segmented using the Kappa test of Kapadia and Pu (2012). The third essay (chapter four) investigates the information content of idiosyncratic volatility around the public release of M&A rumors. We examine the releases of hand-collected initial rumors about potential M&A for 2250 firms. Unlike previous research, we find that a strategy of investing in firms with rumors of lower (greater) credibility yields negative (positive) changes in idiosyncratic volatilities around the rumor dates and subsequent returns. We argue that this asymmetric effect on idiosyncratic volatilities is linked to asymmetric changes in the heterogeneity of the probabilities of actual M&A when conditioned on rumor credibility. Changes in idiosyncratic volatilities are positively related to the market implicit probabilities of M&A as measured by the ratio of the market values at the M&A announcement and rumor dates.

Available in PDF, EPUB and Kindle. Book excerpt: This first volume in a three-volume exposition of Shubik's vision of "mathematical institutional economics" explores a one-period approach to economic exchange with money, debt, and bankruptcy. This is the first volume in a three-volume exposition of Martin Shubik's vision of "mathematical institutional economics"--a term he coined in 1959 to describe the theoretical underpinnings needed for the construction of an economic dynamics. The goal is to develop a process-oriented theory of money and financial institutions that reconciles micro- and macroeconomics, using as a prime tool the theory of games in strategic and extensive form. The approach involves a search for minimal financial institutions that appear as a logical, technological, and institutional necessity, as part of the "rules of the game." Money and financial institutions are assumed to be the basic elements of the network that transmits the sociopolitical imperatives to the economy. Volume 1 deals with a one-period approach to economic exchange with money, debt, and bankruptcy. Volume 2 explores the new economic features that arise when we consider multi-period finite and infinite horizon economies. Volume 3 will consider the specific role of financial institutions and government, and formulate the economic financial control problem linking micro- and macroeconomics.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of three essays on international finance. The first essay is "Exchange rates and Fundamentals". A new open interest rate parity condition that takes account of economic fundamentals is developed from stochastic discount factors (SDFs) of two countries. Through this parity condition, business cycles or fundamentals are linked to exchange rates. Key empirical findings from this parity condition are as follows. First, this model beats the random walk hypothesis: economic fundamentals explain exchange rate movements for high interest rate currencies. Exchange rates of low interest rate currencies act like a random walk because they are less correlated with fundamentals owing to their low risk. For example, U.S. business cycles explain the direction of changes in exchange rates against the dollar. The same thing is true for Japan. Second, this model resolves the forward premium puzzle: the forward premium puzzle is not a general characteristic as regarded in previous studies. It happens when the risk awareness of investors is low, during economic expansions and for low risk currencies. The second essay is "Carry Trade and Global Financial Instability". Carry trade, an opportunistic investment strategy that takes advantage of interest rate differential across countries, is identified the cause of the large-scale depreciations of peripheral currencies in the later half of 2008. A simultaneous equations model, which is derived from a conceptual partial equilibrium model for a local foreign exchange market, is estimated from a cross-sectional sample. The results suggest that the larger appreciation of the yen than the dollar was brought about by a lack of the local supply of the yen rather than a more severe crunch of yen credits. The third essay is "The Economic Origin of Letters of Credit". This essay discusses the economic origin of letters of credit, an instrument widely used in international trade. A game theoretical analysis shows that letters of credit improve efficiency in trade settlements, increasing returns in trade. A few notable facts on letters of credit are discussed. First, the new institution is adopted by merchant banks to maximize their profits and in the process, an improvement in efficiency of international transactions is obtained. Second, the organization established by the legacy institution, bills of exchange, played a critical role in adopting the new institution. Third, the legal enforcement is not essential in this economic institution. Finally, two drivers are identified that improve efficiency of transactions: concentration and projection.

Book excerpt: Essays on Risk and Uncertainty: Insights from Behavioral Economics Sensitization, Excess Volatility, and Extraordinary Persistence It is well-documented that stock prices are more volatile than their underlying fundamentals. A consensus has emerged that time-varying risk-premia are the likely source of this excess volatility, but no consensus has emerged regarding the source of the time-varying risk-premia. Recent microeconomic research suggests that one likely source is that risk preferences are time-varying. This same literature also suggests that variation in risk preferences can be extraordinarily persistent, on the order of decades (see Malmendier, Tate, and Yan (2011)); however this persistence has not been explained by conventional models. In this paper, we derive a model to explain both excess volatility and extraordinary persistence. To do so, we draw from the literatures of medicine, psychology, and behavioral economics. Our basic framework is that people have adaptive emotions and that these adaptive emotions create adaptive risk-aversion. This process is called sensitization, which implies that people become more risk-averse after negative shocks (Kandel 2000). To conduct our analysis, we construct an overlapping generations model of the macroeconomy to study the effect of allowing agents to be sensitized to risk. We find two main results. First, the adaptive nature of risk preferences combined with the finite horizons of agents imply that economic activities, such as investment, are too risky on the intensive margin. Second, excess risk-intensity combined with the availability heuristic implies that agents undertake too little risk (too little investment) on the extensive margin. In order to characterize the optimal monetary policy, we follow Tirole (2006), who models risk through liquidity shocks, and we derive three policy implications for policymakers. First, diversification blunts the impact of time-varying risk aversion. As a result, there is a reason to think that equity financing, under which risk diversification is easier to achieve, leads to fewer risk distortions and faster steady-state growth. Second, countercyclical risk-aversion favors countercyclical monetary policy. Third, short-term asset purchases are shown to exacerbate risk distortions. In our model, monetary policy results in greater stabilization and faster growth when conducted through long-term asset purchases such as Quantitative Easing and Operation Twist. Reference Points, Leaders, and Organizational Culture The work of Akerlof and Kranton (2005) suggests that an organization's culture affects individual behavior by shaping preferences. Yet, within the economics literature, little is known regarding the properties of the optimal culture. In this paper, we use an agency setting to determine the cultural properties that best foster incentives. To do so, we break culture down into three components: a type of performance metric (either production or cost), an expected performance level or target (that serves as the reference point, following Koszegi and Rabin (2006, 2007)), and the degree to which an agent's effort influences the benchmark (referred to as acclimation by Koszegi and Rabin (2006, 2007)). Properties of culture affect agents' consideration of effort. Under the reference-dependent preferences of Koszegi and Rabin (2006, 2007), higher effort increases the likelihood of beating the agent's target (or reference point) as well as increasing the agent's reference point. The magnitudes of these two effects depend critically on the degree of acclimation, whereas the signs of these effects depend on the type of metric used. We present three general findings. First, organizations that rely on production metrics have incentives at least as strong as those relying on cost metrics. Second, the impact of acclimation depends critically on the type of metric used. Under cost metrics, higher acclimation leads to stronger incentives. Under production metrics, higher acclimation leads to weaker incentives. Third, the optimal culture is characterized by production metrics and unacclimating reference points, which we show have implications regarding organizational tenure policies. We conclude with a discussion of testable implications. We refer to the psychology literature and argue that production metrics are most likely to emerge when production is characterized by a high degree of uncertainty, such as in sales. Our model's main prediction is that in these types of environments, we would expect to have rapid production and low tenure in order to lower acclimation. In contrast, environments in which costs are more uncertain are more likely to have cost metrics, which favor longer tenure and loose deadlines in order to generate more acclimating reference points. The Precautionary Principle in Product Markets There any many differences between the U.S. and European regulation, but one notable difference concerns assessments of risk. U.S. and European regulation are concerned about different sources of risk and these sources of risk do not always overlap. As noted by Vogel (2003), U.S. regulation gives more consideration to risk concerning environmental harms, carcinogens in food, and endangered species, whereas European regulation emphasizes risks inherent in biotechnology and carbon emissions. In fact, to justify the regulation of biotechnology, Europeans give explicit emphasis to the Precautionary Principle: faced with an irreversible choice, it is better to presume significant harm. However, when it comes to carcinogens in food, Europeans are relatively more willing to bear the risks. In this paper, we use an agency setting to determine how regulators should manage the risks inherent in new products while not placing an undue burden on potential innovators. Faced with a product quality, they can adhere to the Precautionary Principle and presume harm. Alternatively, they can adhere to the Presumption of Innocence and presume the product is harmless. This paper analyzes which is better. There are two assumptions that separate our analysis from the literature. First, we consider a static framework in which no new information arises. Second, we assume that the equilibrium risk is endogenous. Entrepreneurs' can mitigate harm if given the appropriate incentives and their choices to mitigate harm will be influenced by the regulatory framework chosen by the regulators. We present three main findings. Under the extreme assumptions of risk neutral entrepreneurs, an absence of limited liability constraints, and low levels of potential harm, we show that either the Precautionary Principle or a Presumption of Innocence can achieve the first best outcome when faced with a product of uncertain quality. However, under less extreme assumptions, we identify two factors that favor an approach more consistent with the Precautionary Principle. First, if the dominant concern of the regulators is the limited liability constraint, then relying on the Precautionary Principle will best extract rent. Second, under larger levels of harm, the introduction of agency costs (either due to risk aversion or limited liability) will interact with dynamic complementarities. As the cost to incentivize risk mitigation increases, the equilibrium likelihood of severe harm will rise, and the principle will be more likely to prevent the product from coming to the market. Preventing the product from entering the market reduces the incentives to mitigate harm further. In our model, this dynamic complementarity can only exist when the potential harm is large enough that the product's net benefit to society may be negative.

Available in PDF, EPUB and Kindle. Book excerpt: The scope of this volume is primarily to analyze from different methodological perspectives similar valuation and optimization problems arising in financial applications, aimed at facilitating a theoretical and computational integration between methods largely regarded as alternatives. Increasingly in recent years, financial management problems such as strategic asset allocation, asset-liability management, as well as asset pricing problems, have been presented in the literature adopting formulation and solution approaches rooted in stochastic programming, robust optimization, stochastic dynamic programming (including approximate SDP) methods, as well as policy rule optimization, heuristic approaches and others. The aim of the volume is to facilitate the comprehension of the modeling and methodological potentials of those methods, thus their common assumptions and peculiarities, relying on similar financial problems. The volume will address different valuation problems common in finance related to: asset pricing, optimal portfolio management, risk measurement, risk control and asset-liability management. The volume features chapters of theoretical and practical relevance clarifying recent advances in the associated applied field from different standpoints, relying on similar valuation problems and, as mentioned, facilitating a mutual and beneficial methodological and theoretical knowledge transfer. The distinctive aspects of the volume can be summarized as follows: Strong benchmarking philosophy, with contributors explicitly asked to underline current limits and desirable developments in their areas. Theoretical contributions, aimed at advancing the state-of-the-art in the given domain with a clear potential for applications The inclusion of an algorithmic-computational discussion of issues arising on similar valuation problems across different methods. Variety of applications: rarely is it possible within a single volume to consider and analyze different, and possibly competing, alternative optimization techniques applied to well-identified financial valuation problems. Clear definition of the current state-of-the-art in each methodological and applied area to facilitate future research directions.
