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 Economic Uncertainty Instabilities And Asset Bubbles Selected Essays written by Anastasios G Malliaris and published by World Scientific. This book was released on 2005-10-03 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The compendium of papers in this volume focuses on aspects of economic uncertainty, financial instabilities and asset bubbles.Economic uncertainty is modeled in continuous time using the mathematical techniques of stochastic calculus. A detailed treatment of important topics is provided, including the existence and uniqueness of asymptotic economic growth, the modeling of inflation and interest rates, the decomposition of inflation and its volatility, and the extension of the quantity theory of money to allow for randomness.The reader is also introduced to the methods of chaotic dynamics, and this methodology is applied to asset pricing, the European equity markets, and the multi-fractality in foreign currency markets.Since the techniques of stochastic calculus and chaotic dynamics do not readily accommodate the presence of stochastic bubbles, several papers discuss in depth the presence of financial bubbles in asset prices, and econometric work is performed to link such bubbles to monetary policy.Finally, since bubbles often burst rather than deflate slowly, the last section of the book studies the crash of October 1987 as well as other crashes of national equity markets due to the Persian gulf crisis.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation studies topics in macro-finance with a focus on economic uncertainty. The first chapter (Government Debt and Risk Premia) studies the implications of government debt for asset prices. I document a set of new facts that government debt is related to risk premia in various asset markets.First, the debt-to-GDP ratio positively predicts excess stock returns. The forecast power is compelling, and it outperforms many popular predictors. Second, higher debt-to-GDP ratio is correlated with higher credit risk premia in both corporate bond excess returns and yield spreads. Third, higher debt-to-GDP ratio is associated with lower real risk-free rate. Fourth, higher debt-to-GDP ratio predicts lower average returns on government debt. Expected return variation contributes to a sizable amount of the volatility of the debt-to-GDP ratio. Fifth, debt-to-GDP ratio positively comoves with fiscal policy uncertainty. Fiscal uncertainty also has direct effects on the asset prices consistent with the effect of debt-to-GDP ratio. I rationalize these empirical findings in a general equilibrium model featuring recursive preferences, endogenous growth, and time-varying fiscal uncertainty. In the model, the tax risk premium is sizable and its time variation is driven by fiscal uncertainty. Furthermore, the model generates an endogenous positive relationship between the debt-to-GDP ratio and fiscal uncertainty: fiscal uncertainty increases debt valuation through discount rate channel whereas higher debt conversely raises uncertainty in future fiscal consolidations. In the second chapter (Volatility Risk Pass-Through), we estimate and explain the international transmission of output volatility shocks to both currencies and international quantity dynamics. We produce novel empirical evidence on the relevance of output volatility (vol) shocks for both currency and international quantity dynamics. Focusing on G-17 countries, we document several facts: (1) consumption and output vols are imperfectly correlated within countries; (2) across countries, consumption vol is more correlated than output vol; (3) the pass-through of relative output vol shocks onto relative consumption vol is moderate, especially if the uncertainty shocks originate from small countries; and (4) consumption differentials vol and exchange rate vol are disconnected, in contrast to the perfect correlation implied by a model of perfect risk-sharing with time-additive preferences. We rationalize these findings in a frictionless model with multiple goods and recursive preferences featuring a novel-and-rich risk-sharing of vol shocks. The third chapter (Volatility, Intermediaries, and Exchange Rates) studies how financial market volatility drives exchange rates through the risk management practice of financial intermediaries. We build a model in which the major participants in the international financial market are levered intermediaries subject to Value-at-Risk constraints. Higher portfolio volatility translates into tighter funding conditions and increased marginal value of wealth. Thus, foreign currency is expected to appreciate. Our model can resolve the Backus-Smith puzzle, the forward premium puzzle, and the exchange rate volatility puzzle quantitatively. Our empirical test verifies two implications of the model that both financial market volatility and funding condition measurement have predictive power on exchange rates.

Book excerpt: (cont.) learn about the health of the trading partners of the trading partners of the trading partners, and so on. At some point, the cost of information gathering becomes too unmanageable for banks, uncertainty spikes, and they have no option but to withdraw from loan commitments and illiquid positions. A flight-to-quality ensues, and the financial crisis spreads. The fourth essay, joint with Daron Acemoglu, analyzes the effect of uncertainty of a special kind, that involves economic agents' private actions and anonymous market transactions, on the functioning and efficiency of competitive markets. Despite a sizeable literature, how competitive markets deal with this type of uncertainty remains unclear. A "folk theorem" originating, among others, in the work of Stiglitz maintains that competitive equilibria are always or "generically" inefficient (unless contracts directly specify consumption levels as in Prescott and Townsend, thus bypassing trading in anonymous markets). This essay critically reevaluates these claims in the context of a general equilibrium economy with moral hazard. Our results delineate a range of benchmark situations in which equilibria have very strong optimality properties. They also suggest that considerable care is necessary in invoking the folk theorem about the inefficiency of competitive equilibria with private information.
Download or read book Can It Happen Again written by Hyman Minsky and published by Routledge. This book was released on 2016-04-14 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the winter of 1933, the American financial and economic system collapsed. Since then economists, policy makers and financial analysts throughout the world have been haunted by the question of whether "It" can happen again. In 2008 "It" very nearly happened again as banks and mortgage lenders in the USA and beyond collapsed. The disaster sent economists, bankers and policy makers back to the ideas of Hyman Minsky – whose celebrated 'Financial Instability Hypothesis' is widely regarded as predicting the crash of 2008 – and led Wall Street and beyond as to dub it as the 'Minsky Moment'. In this book Minsky presents some of his most important economic theories. He defines "It", determines whether or not "It" can happen again, and attempts to understand why, at the time of writing in the early 1980s, "It" had not happened again. He deals with microeconomic theory, the evolution of monetary institutions, and Federal Reserve policy. Minsky argues that any economic theory which separates what economists call the 'real' economy from the financial system is bound to fail. Whilst the processes that cause financial instability are an inescapable part of the capitalist economy, Minsky also argues that financial instability need not lead to a great depression. This Routledge Classics edition includes a new foreword by Jan Toporowski.

Book excerpt: This thesis consists of three essays that theoretically and empirically investigate the asset pricing and macroeconomic implications of uncertainty shocks, propose new measures for model robustness, explain the joint dynamics on equity excess returns and real exchange rates. In the first chapter, I show that the effect of uncertainty shocks on asset prices and macroeconomic dynamics depends on the degree of risk sharing in the economy and the origin of uncertainty. I develop a general equilibrium model with imperfect risk sharing and two sources of uncertainty shocks: (i) cash-flow uncertainty shocks, which affect the idiosyncratic volatility of firms' productivity, and (ii) growth uncertainty shocks, which affect the idiosyncratic variability of firms' investment opportunities. My model deviates from the neoclassical setting in one respect: firms' investment policies are set by the experts who are subject to a moral hazard problem and thus must maintain an non-diversified ownership stake in the firm. As a result, risk sharing between experts and other investors is imperfect. Limited risk sharing distorts equilibrium investment choices, firm valuation, and prices of risk in equilibrium relative to the frictionless benchmark. In the calibrated model, the risk premium on growth uncertainty shocks is negative under poor risk sharing conditions and positive otherwise. Moreover, the cross-sectional spread in valuations between value and growth stocks loads positively on the growth uncertainty shocks under poor risk sharing conditions and negatively otherwise. Empirical tests support these predictions of the model. The second chapter is based on the joint work Chen, Dou, and Kogan (2015), in which we propose a new quantitative measure of model fragility, based on the tendency of a model to over-fit the data in sample with poor out-of-sample performance. We formally show that structural economic models are fragile when the cross-equation restrictions they impose on the baseline statistical model appear excessively informative about combinations of model parameters that are otherwise difficult to estimate. We develop an analytically tractable asymptotic approximation to our fragility measure which we use to identify the problematic parameter combinations. Using these asymptotic results, we diagnose fragility in asset pricing models with rare disasters and long-run consumption risk. The third chapter is based on the joint work Dou and Verdelhan (2015), which presents a two-good, two-country real model that replicates the basic stylized facts on equity excess returns and real interest rates. In the model, markets are incomplete. In each country, workers cannot participate in financial markets whereas investors trade domestic and foreign stocks, as well as an international bond. The investors' asset positions are subject to a borrowing constraint, along with a short-selling constraint on equity. Foreign and domestic agents differ in their elasticity of inter temporal substitution and in their risk-aversion. A time-varying probability of a global disaster implies time-varying risk premia in asset markets, and therefore large and time-varying expected valuation effects on international asset positions. The model highlights the role of market incompleteness and heterogeneity across countries in accounting for the volatility of equity and debt international capital flows.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three chapters about how access to financial markets and composition of the labor market determine aggregate macroeconomic outcomes. The first chapter examines the macroeconomic consequences of credit uncertainty using a structural vector autoregression model with stochastic volatility (SVAR-SV). Credit supply conditions in the U.S. is captured by the banks' reports on how credit standards for approving loans have change over time (Bank Lending Standards). The empirical analysis shows that the volatility of macroeconomic and financial variables rises in response to an increase in the credit uncertainty shock. The economic activity falls and credit growth and related interest rates decrease persistently. Moreover, credit volatility shocks explain around 10% of the FEV of endogenous variables. A dissagregated analysis shows that the effect of these shocks are mainly explained by their effects on the corporate business sector. The second chapter studies the role of time-varying credit limits through the lens of a life cycle incomplete markets model calibrated for the U.S. Changes in credit card limits are explained by observable household characteristics and the estimated unobservable variation is quite large. The quantitative exercise shows that even though young households are more indebted in an economy with stochastic borrowing limits, aggregate consumption is not greatly affected by transitory or persistent shocks of this type. However, in the presence of these shocks, households lose the ability to self-insure against other uninsurable idiosyncratic shocks, e.g., labor income shocks. A disaggregated analysis shows that the loss of self-insurance capacity is mainly explained by the effects that stochastic borrowing limits have on the wealth distribution, the precautionary savings channel households have to face unexpected risks. The third chapter studies the role of informal markets to explain economic and demographic variables during a pandemic. The quantitative exercise shows that lockdown policies are less effective in economies with large informal markets, infection and death rates will not decrease as much as formal economies. Moreover, the size of the recession would be exacerbated because informal activities are not counted in the calculation of the GDP. To generate similar results to an economy with only formal markets, the economy with informal markets must implement more severe containment policies.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation studies how financial market volatility or uncertainty in the U.S. economy affects real economic activity both in the U.S. and other open economies. Chapter 1 critically examines a stylized fact about the effects of uncertainty shocks on the U.S. economy. A link between uncertainty and firms' investment, hiring, and production decisions has drawn much attention in contemporary discussions after the 2008 financial crisis. Bloom (2009) showed that uncertainty events, identified by spikes in stock market volatility, triggered immediate falls in output and employment, followed by rapid rebounds. I show that such stock market volatility shocks failed to produce this same pattern of responses after 1983. Chapter 2 studies the effects of risk aversion shocks, measured by increases in the VIX, on emerging market economies (EMEs). By estimating a structural vector autoregression (VAR) model, I find that, although risk aversion shocks do not have much impact on U.S. output, they do have a noticeable impact on the output of EMEs. To explain the contrast between the impact of risk appetite shocks on EMEs and the impact on the U.S. economy, a credit channel is proposed as a propagation mechanism. In the model, an increase in the VIX is translated to a risk-aversion shock that generates a "flight to quality." As international investors pull their money from EMEs, borrowing costs increase and domestic credit falls as a consequence of credit market imperfections. Higher borrowing costs, in turn, lead to a fall in investment that causes a real depreciation and a decline in total output through sectoral linkages. Finally, Chapter 3, which is co-authored with Prakash Loungani, studies the effect of uncertainty shocks on unemployment dynamics by separating out the role of aggregate and sectoral channels. Using SP500 data from the first quarter of 1963 through the third quarter of 2014, we construct a separate index to measure sectoral uncertainty and compare its effects on the unemployment rate with that of aggregate uncertainty in a standard VAR model, augmented by a local projection method. We find that aggregate uncertainty shocks lead to an immediate increase in unemployment, followed by swift reversals. In contrast, sectoral uncertainty shocks have a long-lasting impact on unemployment, with the peak impact occurring after two years. Our findings highlight an additional channel through which uncertainty shocks have persistent effects on unemployment by requiring substantial inter-industry labor reallocation.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis has three essays that study the intersections of macroeconomics, finance, and text analysis. The topics include executives' attention and financial decisions, economic policy uncertainty and stock market forecasting, and the stock market performance in the time of the Covid-19 pandemic. The essays hope to provide unique measurements of attention and uncertainty, empirical evidence, and theories to understand the connections and differences between classic theories and agents' behavior in actual economic activities. The first essay is my job market paper. I examine the attention of executive managers and their financing behavior, focusing on the information acquisition process. Corporations are sensitive to both macroeconomic and firm-specific challenges. Executives must choose overall attention capacity and divide finite attention between these topics. By using natural language processing and quarterly earnings call transcripts, I assess the information content of this dialog. The attention capacity quantifies the effective information used to make borrowing decisions, consisting of information processing macro and firm-specific issues. The attention allocation measures the ratio of attention paid to macroeconomics. Executives make two critical decisions during the information acquiring process. First, executives decide the overall attention capacity, determined by the general uncertainty. Second, executives decide the optimal attention allocated between macro and firm-specific topics. In the rise of uncertainty from either subject, executives' attention capacity increases (scale effect) and assign greater awareness to this topic (substitution effect). I show that the substitution effect is higher than the scale effect. Using an optimal static capital structure model with endogenous information choice, I demonstrate that an executive can tolerate a higher leverage rate when actively acquiring information. Thus, the information decision process is crucial to understanding the recent rising leverage phenomenon.The second essay examines the relationship between the stock market performance and the economic activities in the time of Covid-19. Stock prices and workplace mobility trace out striking clockwise paths in daily data from mid-February to late May 2020. Global stock prices fell 30 percent from February 17 to March 12, before mobility declined. Over the next 11 days, stocks fell another 10 percentage points as mobility dropped 40 percent. From March 23 to April 9, stocks recovered half their losses, and mobility decreased further. From April 9 to late May, both stocks and mobility rose modestly. This dynamic plays out across the 35 countries in our sample, with notable departures in China, South Korea, and Taiwan. The size of the global stock market crash in reaction to the pandemic is many times larger than a standard asset-pricing model implies. Looking more closely at the world's two largest economies, the pandemic had greater effects on stock market levels and volatilities in the U.S. than in China, even before it became evident that early U.S. containment efforts would flounder. Newspaper-based narrative evidence confirms the dominant - and historically unprecedented - the role of pandemic-related developments in the stock market behavior of both countries. The third essay tests the prediction power of the mainland China Economic Policy Uncertainty in forecasting the Chinese stock market. Rational asset pricing theory indicates that the fluctuations of the real economy have a significant impact on the stock market. The Chinese stock market is highly regulated and sensitive to regulations and market policies uncertainty. Using an efficient Dynamic Model Averaging (eDMA) model, this paper investigates how well the newspaper-based Economic Policy Uncertainty (EPU) index can predict the returns of the Chinese Shanghai Stock Exchange Index. Empirical evidence shows that EPU mutes the impact of monetary policy as a predictor. Also, eDMA significantly improves the forecasting performance compared to other forecasting methodologies.
