The geometrical branching model for multiparticle production is used to study the multiplicity dependence of the average transverse momentum /sub n/ of charged particles produced in the central region of pp-bar collisions. The production of jets is shown to be responsible for the increase of /sub n/ with multiplicity. We demonstrate that beyond the plateau region that follows the initial steep rise the jets cause /sub n/ to have a further increase at even higher multiplicities. The physical basis of this ''ledge'' effect is discussed and contrasted from an earlier speculation based on phase transition.
