We study market liquidity via daily close relative spreads and daily traded volumes in a sample of 426 Samp;P500 constituents recorded over the years 2004-2006, a period of quot;normalquot; liquidity conditions. We use recent results on the Generalized Dynamic Factor Model (GDFM) with block...

Classical estimation techniques for linear models either are inconsistent, or perform rather poorly, under α-stable error densities; most of them are not even rate-optimal. In this paper, we propose an original one-step R-estimation method and investigate its asymptotic performances under...

Linear models with stable error densities are considered, and their local asymptotic normality with respect to the regression parameter is established. We use this result, combined with Le Cam's third lemma, to obtain local powers and asymptotic relative efficiencies for various classical rank...

Currency and interest rate swaps are subject to a complex, two sided default risk. Several theoretical papers have recently addressed the problem of pricing this swap credit risk. We implement a recent credit risk pricing model in order to attempt to evaluate one of the main lines of research in...

This paper is devoted to recovery and residual value risks modeling issues of automotive lease portfolios. First, loss given default distributions are estimated and compared for different samples based on risk drivers. Secondly, residual value risk is approached through a re-sampling technique...
