The research in economics at CORE is quite diverse, but researchers share the view that any research, should it be applied or empirical, should be grounded on robust theoretical foundations. While general equilibrium and game theory were the dominating themes when CORE was founded, current research is mostly directed towards applications of theory to a broad variety of problems of market regulation and the organization of the public sector.
