In this paper we develop a formal model that captures some basic features of competition in the mobile communications service industry. In a model of oligopolistic competition with price discrimination and switching costs, we study the role of firms’ installed base of consumers in providing...

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...

This paper models the formation of R&D networks in an industry where firms are technologically heterogenous, extending previous work by Goyal and Moraga (2001). While remaining competitors in the market side, firms share their R&D efforts on a pairwise base, to an extent that depends on their...

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...

The rate of technical change that is characterising both the telecommunications and the computer industry has been a major driver of the evolution of a close and stable system into an open and dynamic one. The introduction of a cluster of new technologies has originated significant changes...

The paper aims at examining the drivers of the adoption of the Internet banking, in order to understand its role with respect to the traditional banking activity and to offer a comprehensive picture of the diffusion of such a technology within the sector. In doing so, it analyses the role of...

The generation of new varieties is crucial for economic growth. The capitalistic mode of production has shown over time a remarkable capability of setting incentives for economic actors to create new products and processes. Concerning the development of new products, the incentives lie in the...
