binding constraints. These constraints induce non-differentiabilities in policy functions. We develop an interpolation … technique that addresses this problem directly: It locates the non-differentiabilities and adds interpolation nodes there. To … handle this flexible grid, it uses Delaunay interpolation, a simplicial interpolation technique. Hence, we call this method …
