Abstract
We study the contact process in \({\mathbb{Z}}\) d and a family of two-parametric oriented percolation models in \({\mathbb{Z}}\) d×\({\mathbb{Z}}\) +. It is proved that the derivative at the endpoint of the critical curve for percolation exists and its absolute value coincides with the critical rate for the corresponding contact process.
