elasticity estimates in many cases considered in the paper. Imposition of curvature alone does not assure regularity, and …We conduct a Monte Carlo study of the global regularity properties of the Normalized Quadratic model. We particularly … investigate monotonicity violations, as well as the performance of methods of locally and globally imposing curvature. We find …
