摘要：
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).
