This book has its origins in a previous volume by the same authors, ``Introduction to Equilibrium Analysis''. Within the context of the exchange economy two solutions or themes proposed by Walras and Edgeworth are developed. The first consists of finding those allocations obtained More...through the decentralization of the choices of individuals by prices. The second, of allocations which are not objected to coalitions by individuals.

This volume should be suitable for final year undergraduate courses or for graduate students. A thorough understanding of the material treated here will be invaluable to the reader in appreciating the economic literature. In particular, he will learn to treat with caution many of the assertions found in that literature.
