Abstract

This study considers a duopoly model in which both a consumer-friendly (CF) firm and a for-profit (FP) firm undertake cost-reducing R&D investments in an endogenous R\&D timing game and then play Cournot output competition. When the CF firm chooses its profit-oriented consumer-friendliness, we show that the consumer-friendliness is non-monotone in spillovers under both simultaneous-move and sequential-move with FP firm’s leadership while it is decreasing under sequential-move with CF firm’s leadership. We also show that a simultaneous-move outcome is a unique equilibrium when the spillovers are low and the CF firm invests higher R&D and obtains higher profits. When the spillovers are not low, two sequential-move outcomes appear and the CF firm might obtain lower profits with higher spillovers under the CF firm leadership.
