Abstract : The aim of the paper is to analyze the impact of heterogeneous beliefs in an otherwise standard competitive complete market economy. The construction of a consensus belief, as well as a consensus consumer, are shown to be valid modulo a finite variation aggregation bias, which takes the form of a discount factor. We then use our construction to rewrite in a simple way the equilibrium characteristics (state price density, market price of risk, risk premium, risk free rate) in an heterogeneous beliefs framework and to analyze the impact of beliefs heterogeneity.
