Complementarity, Equilibrium, Efficiency and Economics

In complementarity theory, several kinds of mathematical models and problems related to the study of equilibrium are considered from the point of view of physics as well as economics. In this book the authors have combined complementarity theory, equilibrium of economical systems, and efficiency in Pareto's sense, discussing the use of complementarity theory in the study of equilibrium of economic systems and present results they have obtained. In addition, they present several results in complementarity theory and several numerical methods for solving complementarity problems associated with the study of economic equilibrium. The most important notions of Pareto efficiency are also presented.
