| Abstract: | Modern science is characterized by an increasing trend in collaborations and interactions among researchers. This paper aims to analyse the effects of this phenomenon on the productivity of the science sector and on the growth rate of the economy. Basic research is modelled as a contest where only those who arrive first at an innovation obtain the reward and where the interactions among researchers do contribute to production of scientific knowledge. An important result is that when interactions are significant multiple steady states emerge. Hence the ‘science globalization’ process could have enhanced the heterogeneity among scientific sectors of different countries. When there are low interactions, policies that increase connectivity could have low or even perverse effect at improving the efficiency of science, the contrary happens in high connectivity environments. |
