This book provides a rigorous course to the theory of intermediate microeconomics. It includes not only the basic traditional theory, but also a "From the Literature" box in each chapter directing students to applications of the theory. The theory is developed axiomatically, with optional sections using one-variable calculus included for interested readers. A substantial number of homework problems are also interspersed throughout the text. Covering the essential topics of microeconomics, this book is highly suitable for a one-term class in microeconomics at the intermediate level.
