’From Abatement to Zone pricing, the reader will find here succinctly yet rigorously defined every concept the IO literature has used in the recent years. The natural place for this book is in the reference section of the library, and teachers of courses in IO, Industrial Economics, Imperfect markets and so on will find that placing it into the reading list will ensure students are in a position not to misuse technical language with very little effort. To sum up, this is an essential text, in both meanings of the word: it captures the essence of the discipline, and it will be indispensable to its practitioners.’
