This paper aims at analyzing the characteristics and the determinants of innovation in the mobile communication service industry, by emphasising in particular the role of demand. In a Shumpeterian spirit, we argue that competition in this sector crucially depends upon innovation, and that, given...

Scientific fraud is a pervasive phenomenon with deleterious consequences, as it leads to false scientific knowledge being published, therefore a¤ecting major individual and public decisions. In this paper we build a game-theoretic model of the research and publication process that ana- lyzes...

The aim of this paper is to extend the theoretical literature on knowledge and network structure by considering explicitly the choice to use the social network as a learning mechanism. In the model, we consider a set of actors that creates and diffuses knowledge. They are located on a lattice...

This paper models the formation of R&D networks in an oligopolistic industry. In particular, it focuses on the coevolutionary process involving firms’ technological capabilities, market structure and the network of interfirm technological agreements.The main result of the paper is that the R&D...

We analyze the effect of competition in market-accessibility enhancement among quality-differentiated firms. Firms are located in regions with different ex-ante transport costs to reach the final market. We characterize the equilibrium of the two-stage game in which firms first invest to improve...

The aim of this paper is to analyze the formation of R&D networks in a setting where spillovers between partners may be imperfect, due to knowledge tacitness, and partner-specific, depending on firms’ technological specializations. We find that firms have strong incentives to use the network...

Authorship and inventorship are “attribution rights” upon which individual scientists build their reputation and career. Social and legal norms concerning their distribution within research teams are currently criticized for failing to inform third parties on individual contributions. We...

We investigate the effect of both research and consulting on higher education teaching quality at the individual level. We propose a theoretical model in which academics allocate limited time between three activities, over a two period horizon, under the assumption of positive spillovers from...

Innovation Networks in Industries provides an extensive study in the fields of industry structure, firm strategy and public policy through the use of network concepts and indicators. It also elucidates many of the complexities and challenges involved.
