This collection of original articles-8 years in the making-shines a bright light on recent advances in financial econometrics. From a survey of mathematical and statistical tools for understanding nonlinear Markov processes to an exploration of the time-series evolution of the risk-return tradeoff for stock market investment, noted scholars Yacine AAmt-Sahalia and Lars Peter Hansen benchmark the current state of knowledge while contributors build a framework for its growth. Whether in the presence of statistical uncertainty or the proven advantages and limitations of value at risk models, readers will discover that they can set few constraints on the value of this long-awaited volume. Presents a broad survey of current research-from local characterizations of the Markov process dynamics to financial market trading activity Contributors include Nobel Laureate Robert Engle and leading econometricians Offers a clarity of method and explanation unavailable in other financial econometrics collectionsLinear martingale estimating functions for diffusion models were studied by Bibby and Sorensen (1995), where they were derived ... where Ac(A, x;9) = Vare(XA|Xo = x) = {DI a F(A, x;6)]2P(A, x, y;9)di/- (3-15) Z The version for multivariate diffusions is defined in an analogous way. ...
