From a given directed weighted network of knowledge links between technology fields, the paper develops a multisector dynamic model of incremental innovation and R&D activity in these fields. The model is focused on the equilibrium share distribution of these variables, which is proved to be...

This paper attempts at fixing some guide-posts on the relation between variety, consumption and growth, while abstracting from the well known effect that variety may exert on productivity, through specialization. A mechanism is first described, through which preference for variety expressed by...

We provide experimental evidence to Binmore and Samuelson’s (1999) insights for modeling the learning process through which equilibrium is selected. They proposed the concept of drift to describe the effect of perturbations on the dynamic process leading to equilibrium in evolutionary games...

This paper contributes to the knowledge-incentive based explanation of R&D networks. It argues that knowledge overlap and novelty are complementary inputs of any R&D alliance, and the complementarity coefficients depend on the incremental or radical nature of the research activity. The relation...
