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 somewhat poorly under stable error densities; most of them are not even rate-optimal. In this paper, we develop an original R-estimation method and investigate its asymptotic performances under stable...

Linear models with stable error densities are considered. The local asymptotic normality of the resulting model is established. We use this result, combined with Le~Cam's third lemma, to obtain local powers of various classical rank tests (Wilcoxon's and van der Waerden's test, the median test,...

This paper evaluates the impact of co-movement in equity return correlations on the equity risk-return trade-off. By applying a principal components analysis on conditional correlations, conditional covariances between the return of a security and the market return are decomposed in a sum of...

I propose a simple econometric model to capture the interaction between commonness and idiosyncrasy in returns on sovereign bonds of Eurozone countries. Common contagion is defined as the impact of yesterday's idiosyncratic shocks on today's common factor. When assuming returns are driven by one...

Starting from the structural model developed by Merton (1974) and the derived notion of distance-to-default, we study the determinants of credit default swap (CDS) spreads for a sample of European banks over a period from January 2006 to December 2011. In particular, we test variables that are...

This paper studies the performance of a sample of funds of hedge funds (FoHFs) from January 1994 to August 2009. We apply the false discoveries (FD) technique of Barras, Scaillet and Wermers (2010) to separate the FoHFs into skilled, zero-alpha and unskilled. We measure the alpha of the FoHFs...
