Students pursuing degrees in economics or business should read Intermediate Microeconomics: A Tool-Building Approach, a straightforward and succinct calculus-based presentation of contemporary microeconomic theory. Techniques for constrained optimization are expressly included in the second edition. The fundamental concepts generally covered at the intermediate level are all included in this wonderfully presented and approachable text, from consumer and producer theory to the market structures of perfect competition, monopoly, duopoly, and oligopoly. Along with chapters on externalities, asymmetric knowledge, and public goods, other subjects covered in the book include general equilibrium, risk, and game theory. Through numerical examples as well as exercises, the book aims to teach microeconomic theory via a process of learning-by-doing. When there is a skill to be acquired, a list of steps outlining the procedure is provided, followed by an example to illustrate how this procedure is carried out. Once learned, students will be able to solve similar problems and be well on their way to mastering the skills needed for future study. Intermediate Microeconomics presents a large amount of material in a concise way, without sacrificing rigor or clarity of exposition. Through use of this text, students will acquire both the analytical toolkit and theoretical foundation necessary in order to take upper-level field courses in economics, such as industrial organization, international trade, and public finance.
