A method in demand analysis based on the Monge-Kantorovich duality is developed. We characterize insatiate demand functions that are rationalized in different meanings by concave utility functions with some additional properties such as upper semi-continuity continuity non-decrease strict concavity positive homogeneity and so on. The characterizations are some kinds of abstract cyclic monotonicity strengthening revealed preference axioms and also they may be considered as an extension of the Afriat-Varian theory to an arbitrary infinite set of observed data . Particular attention is paid to the case of smooth functions. Key words demand function budget set insatiate demand utility function indirect utility function rationalizing strict rationalizing inducing strict inducing Monge-Kantorovich problem MKP with a fixed marginal difference cost function constraint set of a dual MKP concave function strictly concave function positive homogeneous function superdifferential Introduction This article is devoted to concave-utility-rational demand functions. The problem of demand rationalizing is studied in mathematical economics Supported in part by Russian Foundation for Humanitarian Sciences project 03-02-00027 .
