Emphasising interesting and challenging economic applications of mathematics, this text is suitable for courses in mathematical economics at the undergraduate level. Chapters are organised in pairs so that a chapter on economic applications follows a chapter on mathematical theory. Macro applications include ISLM and the Keynesian model, and Micro applications include the Cobb-Douglas model, and utility and profit maximisation. Also covered are the economic applications of static and dynamic game theory. Features: * Chapters are organized in pairs where a chapter on mathematical theory is followed by a chapter on economic applications. This approach allows for flexibility so instructors can tailor the course to their needs. * Macroeconomic applications include ISLM and the Keynesian model, and microeconomic applications include the Cobb-Douglas model, and utility and profit maximization. * Each chapter (except Chapter 1) includes extensive end-of-chapter problems. The solutions to these problems are provided in the Instructor's Manual. * An appendix reviews basic calculus to refresh students' memories. * Economic applications of static and dynamic game theory are covered. * An extensive treatment of constrained optimization includes discussion of inequality constraints and duality.
