The text covers these issues of international trade and finance. The trade theory is based on partial equilibrium market analysis, constant cost and neoclassical general equilibrium, the factor proportions model, and various theories of industrial organization. The text fully integrates concepts from international finance, and a new chapter for the 2nd edition develops the basic models of open economy macroeconomics. The presentation is centered on graphs that use realistic numerical examples making the theory easier for students to grasp, especially when combined with general algebraic and graphic presentations in the classroom. The text does not assume previous courses in intermediate theory or calculus but the theory is completely developed. Numerous exercises that can be presented by students give them confidence in using the theoretical models and concepts.
