Abstract: We derive some Hodge integral identities by taking various limits of the Mariño-Vafa formula using the cut-and-join equation. These identities include the formula of general $\lambda_g$-integrals, the formula of $\lambda_{g-1}$-integrals on ${\overline{\mathcal{M}}}_{g,1}$, the formula of cubic $\lambda$ integrals on ${\overline{\mathcal{M}}}_g$, and the ELSV formula relating Hurwitz numbers and Hodge integrals. In particular, our proof of the MV formula by the cut-and-join equation leads to a new and simple proof of the $\lambda_g$ conjecture. We also present a proof of the ELSV formula completely parallel to our proof of the Mariño-Vafa formula.
