Bertrand competition
Bertrand competition is a model of competition used in economics, named after Joseph Louis François Bertrand (1822-1900). Specifically, it is a model of price competition between duopoly firms which results in each charging the price that would be charged under perfect competition, known as marginal cost pricing. The model has the following assumptions: There are at least two firms producing ho...

We study oligopoly price competition between multiproduct firms, firms whose products interact in the profit function. 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...
