Let φ be a post-critically finite branched covering of a two-sphere. By work of Koch, the Thurston pullback map induced by φ on Teichmüller space descends to a multivalued self-map—a Hurwitz correspondence Hφ—of the moduli space M0, P. We study the dynamics of Hurwitz correspondences via numerical invariants called dynamical degrees. We show that the sequence of dynamical degrees of Hφ is always non-increasing and that the behavior of this sequence is constrained by the behavior of φ at and near points of its post-critical set.
