The dual of Bertrand with homogeneous products is Cournot with perfect complements

Paolo Bertoletti ()

No 490, Working Papers from University of Milano-Bicocca, Department of Economics

Abstract: The quantity-setting (Cournot) oligopoly with perfect complements is dual to the price-setting (Bertrand) oligopoly with homogeneous goods. Under mild technical conditions, the former setting has a unique (pure strategy) Nash equilibrium with null quantities.

Keywords: Cournot duopoly; Bertrand duopoly; perfect complements; homogeneous products. (search for similar items in EconPapers)
