Offering the most cutting-edge coverage available, the 10th edition of the market-leading MICROECONOMIC THEORY: BASIC PRINCIPLES AND EXTENSIONS, INTERNATIONAL EDITION delivers a text that is rigorous yet accessible, accurate in theory yet practical in application, thorough yet concise. Now at a more succinct 19 chapters, this tried-and-true, widely popular text is known as the "bible of microeconomics," offering the most clear and accurate presentation of advanced microeconomic concepts. For the new edition, proven author and economic authority Walter Nicholson is joined by new co-author Chris Snyder, a professor of economics at Dartmouth College. These highly respected economists draw from their wealth of experience in the classroom and the marketplace, giving the book a practical, real-world perspective. Taking a calculus-based approach, MICROECONOMIC THEORY provides an ideal level of mathematical rigor for upper level undergraduate students and beginning graduate students. Extremely reader-friendly, the book is designed to help students truly understand and apply economic models as it enables them to work directly with theoretical tools, real-world applications, and the latest developments in the study of microeconomics. Insightful graphic presentations help visual learners see the connections between the calculus and the algebra/geometry of the same material. In addition, end-of-chapter problems are now presented in two tiers: Simple numerical/mathematical exercises, which build student intuition, are followed by more analytical, theoretical, and complex problems. Unlike other, more theoretical texts, MICROECONOMIC THEORY presents theory in an accessible way as well as illustrates how it applies in the real world.
