This article presents the classic Bertrand model of oligopolistic price competition and shows how alternative assumptions on economic primitives – such as the structure of demand and cost functions, tie-breaking rules, and product differentiation – shape Nash equilibrium prices and profits. We also discuss the related Bertrand–Edgeworth model of price competition in which consumers may be rationed – either strategically or due to capacity constraints – and illustrate how alternative rationing rules influence equilibrium.
