Resumen de Lagrangean conditions for general optimization problems with applications to consumer theory

Carmen Herrero Blanco, José Manuel Gutiérrez Díez

• In this paper we provide Lagrangean conditions in a problem general enough to encompass both the classical quasiconcave optimization problem and the maximization of binary relations.The formal results are applied to consumer theory, providing analytical characterizations of the solution to the consumer problem insome cases where preferences are not representable by continuous utility functions.
