The question addressed by the paper is whether standard procedures and widely accepted insights of competition policy remain valid when one deals with potentially anti-competitive conduct in innovative industries. The question of appropriateness arises because competition in these industries displays features that are radically different from those(More)

In the U.S. in contrast, patent applications are publicly disclosed only when a patent is granted. In this paper we examine the consequences of this difference for (i) firm's R&D and patenting(More)

We analyze the effects of piracy on the pricing policy of a software publisher. Contrary to the existing literature, we focus on the consequences of cost randomness in the decision to use illegal packages of software and on the risk aversion of users and we characterize the optimal prices both under symmetric and asymmetric information. It clearly appears(More)
