Bertrand equilibrium with subadditive costs


  • Dastidar, Krishnendu Ghosh


We show here, in contrast to recent results, that if firms have different cost functions (that are strictly subadditive), such that the 'monopoly breakeven prices' are different, then in a homogeneous product duopoly there is always a Bertrand equilibrium (either in pure strategies or in mixed strategies).
