Keynote Lecture
"Strategy-proofness, domain restrictions and efficient decision-making"

I will review some of the main issues that arise when trying to design mechanisms under which revealing their true characteristics is a dominant strategy for all agents involved. I will start by formulating some early fundamental results in the theory of voting, and will then discuss how they can be extended to more general frameworks. The connections between individual strategy-proofness, group strategy-proofness and efficiency will be discussed. I will emphasize that the possibility of designing satisfactory mechanisms crucially depends on the characteristics of their domains of definition, which reflect the kind and extent of environments on which these mechanisms are expected to operate.
