Empirical evidence about innovation is doubtful in showing incumbent firms' and new entrants' attitude toward radical innovations. Moreover, theoretical works exhibit divergent conclusions when investigating the incentives to innovate. Our paper emphasizes the importance of distinguishing...

We study the relationship between process and product innovations in vertically differentiated duopolies. A process innovation can lead two competing firms to improve the quality of their goods introducing a product innovation. In fact, a cost reducing innovation has two effects: it spurs...

Recent empirical evidence about innovation shows that established firms rarely invest in radical innovation but incrementally improve the existing technology. Revolutionary breakthroughs are more likely to be introduced by new entrants. These stylized facts motivate a renewed attention of the...

In many countries, markets for news are characterized by the coexistence of sources of information which differ as to their contents (in particular, the entertainment/information mix). In this paper we model a market for news where two advertising-supported sources compete for the readers....

This paper proposes a framework for the analysis of the demand- side in the market for news, whereas the existing literature has mainly focused on the supply side. We modeled explicitly the value of information and the demand for news. In particular, the relationship between the level of...

We provide a two-sided model in a vertical di§erentiation context. We solve the model and we calculate the equilibrium in terms of advertising levels, subscription fees and qualities provision, both in duopoly - two platforms of different quality - and in monopoly case. We would like to...
