Hurwitz correspondences are certain multi-valued self-maps of the moduli space M 0, N. They arise in the study of Thurston's topological characterization of rational functions. We compare the dynamics of Hurwitz correspondence H on two different compactifications of M 0, N: the Deligne-Mumford compactification M‾ 0, N, as well as a Hassett space of weighted stable curves. We use this comparison to show that the k-th dynamical degree of H is the absolute value of the dominant eigenvalue of the pushforward induced by H on a natural quotient of H 2 k (M‾ 0, N).
