Generalized Covariance Estimator
We consider a class of semi-parametric dynamic models with iid errors, including the nonlinear mixed causal-noncausal Vector Autoregressive (VAR), Double-Autoregressive (DAR) and stochastic volatility models. To estimate the parameters characterizing the (nonlinear) serial dependence, we introduce a generic Generalized Covariance (GCov) estimator, which minimizes a residual-based multivariate portmanteau statistic. In comparison to the standard m…
Derivative Pricing With Wishart Multivariate Stochastic Volatility
This paper deals with the pricing of derivatives written on several underlying assets or factors satisfying a multivariate model with Wishart stochastic volatility matrix. This multivariate stochastic volatility model leads to a closed-form solution for the conditional Laplace transform, and quasi-explicit solutions for derivative prices written on more than one asset or underlying factor. Two examples are presented: (i) a multiasset extension of…
Testing for Evidence of Adverse Selection in the Automobile Insurance Market
Effet des modes de négociation sur les échanges
The effect of matching procedures on trades The trading systems used on financial markets differ in terms of matching procedures, selected norms to write contracts, existence or not of intermediaries to ensure liquidity, market transparency... We are interested in measuring the direct effect on market specifics of a matching procedure modification namely, the matching frequency and the choice of a unique or multiple prices for the contracts concl…
Pseudo Maximum Likelihood Methods
Pseudo maximum likelihood techniques are applied to basic Poisson models and to Poisson models with specification errors. In the latter case it is shown that consistent and asymptotically normal estimators can be obtained without specifying the p.d.f. of the disturbances. These estimators are compared both from the finite sample and the asymptotic point of view. Quasi generalized PML estimators, which asymptotically dominate all PML estimators, a…
Pseudo Maximum Likelihood Methods
Estimators obtained by maximizing a likelihood function are studied in the case where the true p.d.f. does not necessarily belong to the family chosen for the likelihood function. When such a procedure is applied to the estimation of the parameters of the first order moments, it is possible to prove a necessary and sufficient condition for its consistency. Asymptotic normality is shown as well as the existence of a lower bound for the asymptotic …
