Abstract

We study a quantity-setting duopoly and a price-setting duopoly in which each firm has the option of disclosing or not its cost-reducing R&D investment. Each firm’s R&D outcome (or, its new marginal cost) is deterministically determined, and thus, when making its R&D investment, each firm is certain about its R&D outcome. We consider the following game. In the first stage, each firm decides and announces whether it will disclose its R&D investment. Next, each firm chooses−and discloses if it announced to do so−its R&D investment. Finally, the firms choose their output levels [prices] simultaneously and independently. When choosing its output level [price], each firm knows the other firm’s new marginal cost only if the other firm disclosed its R&D investment. We show in both models that each firm discloses its R&D investment.
