The steady Eikonal equation is a prototypical first-order fully nonlinear equation. A numerical method based on elliptic solvers is presented here to solve two different kinds of steady Eikonal equations and compute solutions, which are maximal and minimal in the variational sense. The approach in this paper relies on a variational argument involving penalty, a biharmonic...

In this article, we discuss a numerical method for the computation of the minimal and maximal solutions of a steady scalar Eikonal equation. This method relies on a penalty treatment of the nonlinearity, a biharmonic regularization of the resulting variational problem, and the time discretization by operator-splitting of an initial value problem associated with the Euler-Lagrange...

In this paper, we test for scope effects in Contingent Valuation applying different distributional assumptions for WTP, a non-parametric estimation and an estimation based on an open-ended format. Mean WTP is sensitive to the distributional assumption, but so is the scope effect. The nonparametric model, without conditions on the distribution, is the best able to identify scope...
