Abstract: The volume Bcomb(G) of the unit ball — with respect to the combinatorial length function lG — Σ of the space of measured foliations on a stable bordered surface Σ appears as the prefactor of the
polynomial growth of the number of multicurves on Σ. We find the range of s ∈ R for which
(Bcomb)s, as a function over the combinatorial moduli spaces, is integrable with respect to the Σ
Kontsevich measure. The results depends on the topology of Σ, in contrast with the situation for hyperbolic surfaces where [6] recently proved an optimal square-integrability.
