Presenting advanced topics in financial econometrics and theoretical finance, this guide is divided into three main parts. The first part aims at documenting an empirical regularity of financial price changes: the occurrence of sudden and persistent changes of financial markets volatility. This phenomenon, technically termed "stochastic volatility", or "conditional heteroskedasticity", has been well known since before 1980; in this part, further useful theoretical properties of conditionally heteroskedastic models are uncovered. The second section goes beyond the statistical aspects of stochastic volatility models: it constructs and uses fully articulated, theoretically-sounded financial asset pricing models that allow for the presence of conditional heteroskedasticity. The third part demonstrates how the inclusion of the statistical aspects of stochastic volatility in a rigorous economic scheme can be faced from an empirical standpoint.

Stochastic Volatility in Financial Markets presents advanced topics in financial econometrics and theoretical finance, and is divided into three main parts.

Fixed income volatility and equityvolatility evolve heterogeneously over time, co-moving disproportionatelyduring periods of global imbalances and each reacting to events of differentnature. While the methodology for options-based "model-free" pricingof equity volatility has been known for some time, little is known aboutanalogous methodologies for pricing various fixed income volatilities.This book fills this gap and provides aunified evaluation framework of fixed income volatility while dealing withdisparate markets such as interest-rate swaps, government bonds, time-depositsand credit. It develops model-free, forward looking indexes of fixed-incomevolatility that match different quoting conventions across various markets, anduncovers subtle yet important pitfalls arising from naïve superimpositions ofthe standard equity volatility methodology when pricing various fixed incomevolatilities.
