In this paper, we establish the global $C^{2,\alpha}$ and $W^{2,p}$
regularity for the Monge-Amp\`ere equation $\det\,D^2u = f$ subject to boundary
condition $Du(\Omega) = \Omega^*$, where $\Omega$ and $\Omega^*$ are bounded
convex domains in the Euclidean space $\mathbb{R}^n$ with $C^{1,1}$ boundaries,
and $f$ is a H\"older continuous function. This boundary value problem arises
naturally in optimal transportation and many other applications.
