International Economics

A comprehensive, exam-focused guide to International Economics, covering the Ricardian model of comparative advantage, the Heckscher-Ohlin model and Stolper-Samuelson theorem, tariff and trade policy welfare analysis, floating and fixed exchange rate systems, purchasing power parity and interest rate parity, the balance of payments, the Mundell-Fleming model and the impossible trinity, currency crises, protectionism arguments, and exchange rate regime choice. Includes a custom foreign exchange market diagram, fully worked problems (comparative advantage calculation, impossible trinity application, tariff welfare analysis), comparison tables clarifying commonly confused trade and finance concepts, a 10-term glossary, and original practice questions with detailed explanations. Built around the theoretical frameworks (comparative advantage, the impossible trinity) that connect trade theory to real-world policy debates.
