The Economics of Adjustment and Growth is an exciting book, focusing on the challenges facing researchers and policymakers in the design and implementation of macroeconomic policies in developing countries. The book is very well written, with a nice balance between a clear exposition of models and an overview of their empirical applications. It summarizes the current state of knowledge and recent experience with policies. I highly recommended it to advanced undergraduate and graduate students interested in applied policy issues, as well as practitioners interested in gaining insight into current models and applications.
