This work investigates the theoretical underpinnings of general economic equilibrium when firms are price-makers rather than price-takers. It explores the mathematical models and assumptions necessary to construct such a framework. The book delves into the complexities of market dynamics where individual firms possess the ability to influence prices, moving beyond simpler competitive models.

The 'Lecture Notes in Economics and Mathematical Systems' series typically publishes advanced, rigorous academic material. This volume likely presents a specialized theoretical treatment of its subject, aimed at graduate students and researchers in economics and mathematical economics. The focus on theoretical models suggests a dense, analytical approach rather than an introductory overview.
