Mean-field solution for a mixed population of agents.
For a fixed fraction of non-naive agents we plot the steady-state efficiency versus the noise amplitude . We consider two scenarios: (a) agents with no opinion bias and (b) agents with an opinion bias (see text). Continuous lines show stable solutions, and discontinuous lines show unstable solutions. The maroon regions show the set of initial conditions for which The orange region covers for which The green region covers initial conditions for which . In (b), blue dots show for the initial condition indicated by the dotted blue line. Blue arrows indicate the steady-state solution that corresponds to the initial condition represented by the blue dotted line.
