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). These extensionsinclude higher-moments asset pricing models (see Jurczenko and Maillet, 2006),conditional asset pricing models (see Bollerslev et al., 1988, and Jondeau andRockinger, 2004). Estimations […]

To do this, we build an original dataset of chemical explosionsthat occurred worldwide from 1990-2005. First, our results show that news coverage increaseswith the social and environmental consequences of the accident. Second, to deal with the factthat news coverage is determined simultaneously with stock returns, we […]

First, regarding the issue of poverty identification, the approach isless restrictive than the traditional “union” and “intersection” views. Secondly,concerning the issue of aggregation among attributes for each individual, it allowsfor […]

Mardi | 2009-02-24 Eleni ILIOPULOS – Yannick LUCOTTE In this article, we focus on current account dynamics in large openeconomies characterized by debt-constrained heterogeneous agents andendogenous monetary policies. We incorporate three key features thathave bulked large in the New Open Macroeconomics literature: i) homebias in trade ii) price rigidities and iii) durable goods (real properties).In order to limit agents’ willingness to consume and to (partially) insurecreditors against the risk of default, we incorporate collateral constraints.We show that the impatience of […]
