Over the last 20 years, applied general equilibrium (AGE) modelling has developed from a small academic research program into a routinely used policy assessment tool. Major governments and international agencies maintain AGE research groups, and call for their input to a variety of trade, tax, and other resource allocation issues. This book is a collection of papers representative of recent activity in this field. Contributions have been grouped into a methodological section, a trade section, and a section on energy issues, and this division accurately indicates the focus of the volume. Readers will thus have access to up to date techniques and results currently being used by researchers at the forefront of the research program.
