OverviewNow you can truly understand and apply the latest economic models as you work directly with theoretical tools, real-world applications, and the popular new behavioral economics in this reader-friendly, market-leading book. MICROECONOMIC THEORY: BASIC PRINCIPLES AND EXTENSIONS, 12E takes a calculus-based approach to provide the ideal level of mathematical rigor, whether you are an upper-level undergraduate or beginning graduate student. Insightful graphic presentations help you visually grasp the connections between the calculus and the algebraic and geometric approach to the same material. End-of-chapter problems present simple numerical/mathematical exercises, which strengthen your microeconomic intuition and are followed by more analytical, theoretical, behavioral, and complex problems. Unlike other more theoretical texts, MICROECONOMIC THEORY, 12E closely connects all theory to real applications in the world today.
