Nonparametric estimation of concave production technologies by entropic methods

An econometric methodology is developed for nonparametric estimation of concave production technologies. The methodology, bases on the priciple of maximum likelihood, uses entropic distance and concvex programming techniques to estimate production functions.convex programming, production functions, entropy

Matrix criteria for the Pseudo-P-convexity of a quadratic form

AbstractExcept for the family of quasiconvex quadratic functions, no characterization of generalized convex quadratic forms on convex sets in Rk exists. We characterize pseudo-P-convex quadratic functions (i.e., bi-pseudoconvex quadratics for which every stationary point is a global minimum) on solid convex sets in Rn×Rm
