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...

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 extends the LSDV bias approximations in Bun and Kiviet (2003) to unbalanced panels. The approximations are obtained by modify-ing the within operator to accommodate the dynamic selection rule. They are accurate, with higher order terms bringing only decreasing improve-ments to the...
