This paper analyzes the impact of simultaneous increases in piracy (piracy effect) and network externalities (network effect) on R&D investment. A single firm's R&D investment increases (or decreases) if the network effect (or piracy effect) is dominant. With R&D competition, if the firms...

This paper deals with projects’ performance. To be more precise, we endeavor to redeem the concept of commercial failure, by making a critical appraisal of certain works on innovation journey. We show that product innovation is not always characterized by a stream of interdependent projects....

This paper asks whether there is evidence of higher innovation output from firms where there is more foreign activity in terms of foreign direct investments (FDI), trade and collaboration on innovation, or if proximity between innovators is more important. With a sample of about two-thirds of...

Investment decision-making is modeled by means of a Kohonen neural net, whose neurons represent firms as decision-makers. Thus, the network reconstructs collective decision-making by the productive system. This model focuses on the decision to invest in novel fields of activity, which requires...

Innovation is a multilevel phenomenon. Not only characteristics of firms but also environment within which firms operate matter. Although this has been for long recognized in the literature, a quantitative test that explicitly concerns the hypothesis that framework conditions affect...

This paper contains an empirical dynamic model of supply and demand in the market for digital cameras with endogenous product innovation. On the demand side, heterogeneous consumers time optimally the purchase of goods depending on the expected evolution of prices and characteristics of...
