The presented model unifies two seminal frameworks: growth driven by horizontal R&D activities and growth driven by vertical R&D activities. We respectively use the model of ...

Exploiting the formalization of Salop (1979), we propose a fully endogenous Schumpeterian model explicitly considering that each innovation influences a more or less significant range of sectors. Besides encompassing most models of the related literature, this framework enables us to reassess the issue of scale effects, showing that most frameworks developed to remove scale effects amount to assuming no inter-sectorial diffusion of knowledge, and that, it is possible to eliminate scale effects while maintaining the effects of public policies, but without suppressing knowledge diffusion.

Following the suggestions of several authors like Arrow (1962), Dasgupta et-al (1996), Scotchmer (1991, 1999), Lerner and Tirole (2002) we define specific markets and specific prices for the discoveries produced by researchers. We

We treat the ques- tion of research funding in a model without including any intermediate goods production sector. We assume that the users of discoveries reward directly innovators that own a patent on their innovations. We
