Our first and greatest acknowledgement is to Taimoon Stewart, the lead author of an earlier IDRC report (Stewart et al. 2007), and to Julian Clarke, co-author of that work along with Susan Joekes. The present book is based heavily on that earlier study, which represented the first attempt to synthesize and distill the lessons from the findings of a number of IDRC-funded research projects carried out since 2002. The researchers in Armenia and Zambia, Argentina and Uzbekistan, Jamaica and South Africa, Egypt and Peru, Costa Rica and India, Switzerland and France— and many other countries besides—who carried out all those studies have our gratitude and admiration for their work. Their efforts have amply justified IDRC's decision to fund research on competition policy. Special thanks are also due to Barbara Lee, Peter Holmes, who acted as special adviser to IDRC and helped inspire and shape the IDRC work on competition policy, and Luis Abugattas, for his ongoing support in different capacities.
