  • Extensive Social Choice and the Measurement of Group Fitness in Biological Hierarchies 

    Bossert, Walter; QI, Chloe X.; Weymark, John A. (Université de Montréal. Département de sciences économiques., 2012-07)
    Extensive social choice theory is used to study the problem of measuring group fitness in a two-level biological hierarchy. Both fixed and variable group size are considered. Axioms are identified that imply that the group measure satisfies a form of ...
