Dynamical interplay between local connectivity and global competition in   a networked population
  We show, both numerically and analytically, that the consequences of 'wiring up' a competitive population depend quite dramatically on the interplay between the local connectivity and the global resources. With modest global resources, adding small amounts of local connectivity yields an increasingly heterogeneous population. With substantial global resources, high-performing yet reasonably homogenous collective states emerge instead.
