Book excerpt: This book addresses the broader questions of how both the content and the context of public policy affect its implementation. Through a series of case studies from Mexico, Peru, Brazil, Colombia, Zambia, Kenya, and India, ten scholars here demonstrate that numerous factors intervene between the statement of policy goals and their actual achievement in society. Originally published in 1980. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
