Social responsibility in a bilateral monopoly with R&D

This note examines social responsibility in a linear bilateral monopoly by incorporating a cost-reducing R&D investment and investigates an endogenous timing game. We find that in the presence of R&D, the retailer always adopts social responsibility irrespective of the timing of the game, but the manufacturer adopts only with its leadership in a sequential game where it can take the first-mover advantage. We also show that two sequential choices will be subgame perfect equilibria, but the commitment to the social responsibility by manufacturer is a payoff dominance outcome.
