This is the first book to teach the basic methods of proof and problem solving in General Equilibrium Theory at graduate level. The problems cover the entire spectrum of difficulty: some are routine, while others require a good grasp of the material involved, and some are even challenging. In searching for the basic required techniques, students will discover a wealth of new material, and are encouraged to arrive at solutions different from the ones presented in the book. Complete solutions to two hundred problems are provided.

1. The Arrow-Debreu Model.- 2. Riesz Spaces of Commodities and Prices.- 3. Markets With Infinitely Many Commodities.- 4. Production With Infinitely Many Commodities.- 5. The Overlapping Generations Model.
