    Let \(D\subset\mathbb C^n\) be a bounded locally convexifiable domain of finite type \(m\). Then \(\frac{g_D(z,w)}{G_D(z,w)}\leq C(D)\|z-w\|^{2(n-m)}\), \(z,w\in D\), where \(g_D\) (resp. \(G_D\)) denotes the pluricomplex (resp. classical) Green function for \(D\). In the case where \(D\) is strongly pseudoconvex the result was proved by \textit{M. Carlehed} [ Mich. Math. J. 45, 399-407 (1998; Zbl 0960.32021)]. Moreover, the author shows that if \(m>n\) is even, then for the domain \(D:=\{z\in\mathbb C^n: |z_1|^2+|z_2|^m+\dots+|z_n|^m<1\}\) (\(D\) is a convex domain of type \(m\)) the quotient \(g_D/G_D\) is unbounded.
