Imposing curvature restrictions on flexible functional forms. (English) Zbl 0573.62098
A general computational method for estimating the parameters of a flexible functional form subject to convexity, quasi-convexity, concavity, or quasi-concavity at a point, at several points, or over a region, is set forth and illustrated with an example.
