Mardi | 2009-05-05 Patrick KOUONTCHOU – Bertrand MAILLET – Sessi TOKPAVI In this paper we present and extend the approach of Bollerslev and Zhang (2003)for “realized” measures and co-measures of risk in some classical asset pricingmodels, such as the Capital Asset Pricing Model (CAPM) of Sharpe (1964) andthe Arbitrage Pricing Theory (APT) model by Ross (1976).

Mardi | 2009-04-14 B103 Marie-Aude LAGUNA – Audrey LAUDE Using the event-study methodology and multivariate regressions, this paper examinesthe intensity of media coverage, its determinants and its marginal effect on stock returnsfollowing chemical disasters.

Second, to deal with the factthat news coverage is determined simultaneously with stock returns, we […]
