This paper investigates the strategic choice between introducing a process or a product innovation in a duopoly model with vertical differentiation, comparing the outcomes in case of Bertrand and Cournot competition. It is shown that under both competitive regimes three equilibria in innovation adoption may arise: two symmetric equilibria, where firms select the same innovation type, and one asymmetric equilibrium. The competitive regime has an impact on the features of the asymmetric equilibrium, since in case of Bertrand competition, the high (low) quality firm chooses a product (process) innovation, while firms make the opposite choices in case of Cournot competition. The presence of a leapfrogging effect (only in the Cournot case) explains these different outcomes. Last, we find that the Cournot competitors tend to favor the introduction of a new product in comparison with the Bertrand competitors.
