Abstract

This paper analyses the consequences of young researchers' scientifc choice on the dynamics of sciences. We develop a simple two state mean field game model to analyze the competition between two paradigms based on Kuhn's theory of scientifc revolutions. At the beginning of their career, young researchers choose the paradigm in which they want to work according to social and personal motivations. Despite the possibility of multiple equilibria the model exhibits at least one stable solution in which both paradigms always coexist. The occurrence of shocks on the parameters may induce the shift from one dominant paradigm to the other. During this shift, researchers' choice is proved to have a great impact on the evolution of sciences.
