Simulated nonparametric estimation of dynamic models with applications to finance

Altissimo, Filippo; Mele, Antonio - London School of Economics (LSE) - 2005

This paper introduces a new class of parameter estimators for dynamic models, called Simulated Nonparametric Estimators (SNE). The SNE minimizes appropriate distances between nonparametric joint (or conditional) densities estimated from sample data and nonparametric joint (or conditional)...

Efficient estimation of a semiparametric characteristic-based factor model of security returns

Connor, Gregory; Hagmann, Matthias; Linton, Oliver - London School of Economics (LSE) - 2007

This paper develops a new estimation procedure for characteristic-based factor models of security returns. We treat the factor model as a weighted additive nonparametric regression model, with the factor returns serving as time-varying weights, and a set of univariate non-parametric functions...

Does beta move with news?: Systematic risk and firm-specific information flows

Patton, Andrew J.; Verardo, Michela - London School of Economics (LSE) - 2009

This paper shows that the systematic risk (or "beta") of individual stocks increases by an economically and statistically signi…cant amount on days of firm-specific news announcements, and reverts to its average level two to five days later. We employ intra-daily data and recent advances in...

Systematic credit risk: CDX index correlation and extreme dependence.

Aboura, Sofiane; Wagner, Niklas - Université Paris-Dauphine - 2008

Dependence is an important issue in credit risk portfolio modeling and pricing. We discuss a straightforward common factor model of credit risk dependence, which is motivated by intensity models such as Duffie and Singleton (1998), among others. In the empirical analysis, we study dependence...

A Class of Models satisfying a Dynamical Version of the CAPM.

Napp, Clotilde; Jouini, Elyès - Université Paris-Dauphine - 2003

Under a comonotonicity assumption between aggregate dividends and the market portfolio, the CCAPM formula becomes more tractable and more easily testable. In this paper, we provide theoretical justifications for such an assumption.
