La situation de l ’ allaitement maternel en Algérie en 2002
L’allaitement maternel est un élément naturel du comportement de l’être humain, mais il a, au cours des temps, été entouré de règlements et d’aversions.

Specifically, we focus on the impact of intra-firm product interactions on the level of equilibrium profits. This impact is divided into two effects: a direct effect and a strategic effect (i.e., through the competitors’ actions). We derive conditions such that the strategic ef...
متن کاملBertrand Competition Under Uncertainty
Consider a Bertrand model in which each rm may be inactive with a known probability, so the number of active rms is uncertain. This activity level can be endogenized in any of several ways{ as whether to incur a xed cost of activity, as output choice, or as quality choice. Our model has a mixed-strategy equilibrium, in which industry pro ts are positive and decline with the number of rms, the s...

Since at least Engle (1982) and Stock and Watson (2002), we know that the conditional variance of future output and inflation evolves over time. However, in these seminal contributions, the risk of real activity and inflation is implicitly considered as symmetric. In this paper, we investigate the time evolution of the conditional distribution of macroeconomics variables with a special interest...
