This volume provides a practical guide to building and using simulation models for international trade theory and policy. Through a sequence of carefully constructed and fully documented programs, the volume illustrates how GAMS can be used to analyze a wide array of problems. Modern computable general equilibrium (CGE) models for trade policy are challenging in their complexity, but can be thought of as constructions of much simpler building blocks. By developing the building blocks in a consistent manner, and then putting them together in more complex and interesting ways, the volume makes CGE accessible to anyone with a background in microeconomics/trade theory. The volume will be useful to graduate students and researchers in international trade looking for a detailed guide to building simulation models and to developing the skill set necessary to enter into the world of CGE modeling. Key Features: • Unlike existing treatments, the topic is approached from the perspective of international trade theory, as opposed to computable general equilibrium. This approach not only clearly links CGE techniques to their foundation in theory, but also makes the complex models used in CGE more accessible to those with a background in trade theory rather than programming • The book uses a modular approach, with each of the components of modern models that are used for CGE analysis of trade policy developed in short, self-contained sections that are simple, built in a consistent way, and familiar from standard microeconomics/trade theory, but can be combined in increasingly complex ways • The treatment contains numerous examples of the exact programming required, with codes described step-by-step and in detail, and available for download. The material can quickly be adopted and adapted to new problems
