Volatility Comovement


Book Description

We implement a multifrequency volatility decomposition of three exchange rates and show that components with similar durations are strongly correlated across series. This motivates a bivariate extension of the Markov-Switching Multifractal (MSM) introduced in Calvet and Fisher (2001, 2004). Bivariate MSM is a stochastic volatility model with a closed-form likelihood. Estimation can proceed by ML for state spaces of moderate size, and by simulated likelihood via a particle filter in high-dimensional cases. We estimate the model and confirm its main assumptions in likelihood ratio tests. Bivariate MSM compares favorably to a standard multivariate GARCH both in- and out-of-sample. We extend the model to multivariate settings with a potentially large number of assets by proposing a parsimonious multifrequency factor structure.







Multifractal Volatility


Book Description

Calvet and Fisher present a powerful, new technique for volatility forecasting that draws on insights from the use of multifractals in the natural sciences and mathematics and provides a unified treatment of the use of multifractal techniques in finance. A large existing literature (e.g., Engle, 1982; Rossi, 1995) models volatility as an average of past shocks, possibly with a noise component. This approach often has difficulty capturing sharp discontinuities and large changes in financial volatility. Their research has shown the advantages of modelling volatility as subject to abrupt regime changes of heterogeneous durations. Using the intuition that some economic phenomena are long-lasting while others are more transient, they permit regimes to have varying degrees of persistence. By drawing on insights from the use of multifractals in the natural sciences and mathematics, they show how to construct high-dimensional regime-switching models that are easy to estimate, and substantially outperform some of the best traditional forecasting models such as GARCH. The goal of Multifractal Volatility is to popularize the approach by presenting these exciting new developments to a wider audience. They emphasize both theoretical and empirical applications, beginning with a style that is easily accessible and intuitive in early chapters, and extending to the most rigorous continuous-time and equilibrium pricing formulations in final chapters. - Presents a powerful new technique for forecasting volatility - Leads the reader intuitively from existing volatility techniques to the frontier of research in this field by top scholars at major universities - The first comprehensive book on multifractal techniques in finance, a cutting-edge field of research

The Oxford Handbook of Computational Economics and Finance


Book Description

The Oxford Handbook of Computational Economics and Finance provides a survey of both the foundations of and recent advances in the frontiers of analysis and action. It is both historically and interdisciplinarily rich and also tightly connected to the rise of digital society. It begins with the conventional view of computational economics, including recent algorithmic development in computing rational expectations, volatility, and general equilibrium. It then moves from traditional computing in economics and finance to recent developments in natural computing, including applications of nature-inspired intelligence, genetic programming, swarm intelligence, and fuzzy logic. Also examined are recent developments of network and agent-based computing in economics. How these approaches are applied is examined in chapters on such subjects as trading robots and automated markets. The last part deals with the epistemology of simulation in its trinity form with the integration of simulation, computation, and dynamics. Distinctive is the focus on natural computationalism and the examination of the implications of intelligent machines for the future of computational economics and finance. Not merely individual robots, but whole integrated systems are extending their "immigration" to the world of Homo sapiens, or symbiogenesis.




Financial Markets and Public Information


Book Description

The last decades have seen dramatic changes in trading technology and the way that financial markets operate. As trading technology advances, news providers have kept pace and deliver news to market participants around the world within fractions of a second using electronic systems. Currently, most news is still interpreted by humans but news providers have started to offer newswire products with machine learning systems that specifically cater to algorithmic traders. In practice, newswire messagesmake up a major part of the public information set available to investors. This book studies how newswire messages impact modern electronic equity markets.




Handbook of Monetary Policy


Book Description

This handbook explains the development and implementation of monetary policy. It examines theories and issues related to the preservation of economic activity and explores why the preservation of economic stability is a principal goal of public policy.




Global Financial Stability Report, October 2016


Book Description

The current report finds that short-term risks to global financial stability have abated since April 2016, but that medium-term risks continue to build. Financial institutions in advanced economies face a number of cyclical and structural challenges and need to adapt to low growth and low interest rates, as well as to an evolving market and regulatory environment. Weak profitability could erode banks’ buffers over time and undermine their ability to support growth. A cyclical recovery will not resolve the problem of low profitability. More deep-rooted reforms and systemic management are needed, especially for European banks. The solvency of many life insurance companies and pension funds is threatened by a prolonged period of low interest rates. Corporate leverage in emerging market economies remains elevated in some countries, but the current favorable external environment presents an opportunity for overly indebted firms to restructure their balance sheets. The political climate is unsettled in many countries. A lack of income growth and a rise in inequality have opened the door for populist, inward-looking policies. These factors make it even harder to tackle legacy problems and further expose economies and markets to shocks. A potent and more balanced policy mix is needed to deliver a stronger path for growth and financial stability, and avoid slipping into a state of financial and economic stagnation. The report also examines how the rise of nonbank financing has altered the impact of monetary policy and finds that fears of a decline in the effectiveness of monetary policy are unfounded. It appears that the transmission of monetary policy is, if anything, stronger in economies with larger nonbank financial sectors. Finally, the report examines the link between corporate governance, investor protection, and financial stability in emerging market economies. It finds that the improvements over the past two decades have helped bolster the resilience of their financial systems. These benefits strengthen the case for further reform.




Macroeconomic Policies in the World Economy


Book Description

The integration of goods and financial markets has progressed on a global scale in recent years. Thus, the cyclical patterns in the world economy may have changed too. Against this background, experts in international economics analyze the synchronization of business cycles and their volatility in this book. Is there an European business cycle? What is the role of multinational corporations and monetary policy in transmitting business cycles? Further, they discuss the need and feasibility of internationally coordinating monetary and exchange rate policies and the quantitative effects of tax competition.




Financing Agriculture Into The Twenty-first Century


Book Description

This volume is concerned with the paradigm shifts occurring in U.S. agriculture and its related financial services sector. The U.S. agricultural sector is undergoing rapid change with large segments commonly described as industrialized. Often observers focus on the technological and structural changes that the sector is undergoing and ignore other
