Abstract

For courses in microeconomics.

 

Exploring Microeconomics: Formal Theory and Practical Problems

Significantly revised and updated with new real-world examples, exercises, and applications, this Fourth Edition of Microeconomics: Theory and Applications with Calculus remains the premiere microeconomics text to marry formal theory with robust, thoroughly analyzed real-world problems.

 

Intended as an intermediate microeconomics text, Perloff introduces economic theory through a combination of calculus, algebra, and graphs. The text integrates estimated, real-world problems and applications, using a step-by-step approach to demonstrate how microeconomic theory can be applied to solve practical problems and policy issues. Compared to other similar texts, the author also places greater emphasis on using contemporary theories–such as game theory and contract theory–to analyze markets.
