ACKNOWLEDGEMENTS

As authors and contributors to this book, we have worked as an intellectual team among ourselves and with colleagues and students. Many techniques arose in conversation, and were developed by being passed around, critiqued, commented upon, improved, and reassessed iteratively, in theory and in practice, before they were written down systematically.

Many others also contributed definitive insights to this creative process.

The materials for this book developed greatly over a series of two-week intensive summer schools that we held in Delhi (2008), Lima (2009), Santiago and Amman (2010), Delft (2011), Jakarta (2012), Washington DC and Managua (2013), and Oxford (2014). We are grateful to our students, and to our other colleagues, for the learning that occurred together on those occasions. We also presented materials from this book in our lunchtime seminar series, and in conferences and workshops, and benefited tremendously from the exchanges that ensued.

We received very helpful comments, corrections, improvements, and suggestions from many across the years, and are especially indebted to Tony Atkinson who read the full manuscript. We are also grateful for direct comments from the following: Khalid Abu-Ismail, Sudhir Anand, Gordon Anderson, Roberto Angulo, Kaushik Basu, Francois Bourguignon, Cesar Calvo, Satya Chakravarty, Mihika Chatterjee, Adriana Conconi, Conchita DAmbrosio, Jorge Davalos, Koen Decancq, Sdverine Deneulin, Jean Dreze, Jean-Yves Duclos, Indranil Dutta, Marc Fleurbaey, Betti Gianni, Lu Gram, John Hammock, Bouba Housseini, Stephan Klasen, Jeni Klugman, Jaya Krishnakumar, Guy Lacroix, Achille Lemmi, Xavier Mancero, Enrica Chiappero Martinetti, Adib Nehmeh, Brian Nolan, Prasanta Pattanaik, Natalie Quinn, Amartya Sen, Jacques Silber, Frances Stewart, Joanne Tomkinson, Nicolas Van de Sijpe, Ana Vaz, Christopher Whelan, Gaston Yalonetzky, and Asad Zaman.

We have deeply appreciated the attentive and gentle support of Ann Barham, who corrected English and other matters throughout the whole text, and of Maarit Kivilo, who assembled the bibliography with exquisite precision and good humour. Research assistants included Garima Sahai, who expertly processed dozens of literature searches and organized the pdf files at the start of this project, and Alejandro Olayo-Mdndez SJ, who steered the project calmly to its conclusion. Elizaveta Fouksman provided substantive and thoughtful pieces of analysis on a regular basis. Timely, insightful, and very pertinent inputs came from research assistants, including Aparna John, ArifNaveed, Esther Kwan, Felipe Roa-Clavijo, Laurance Eschamps-Laporte, Maria Mancilla Garcia, Putu Natih, Saite Lu, and Franziska Mager.

A book is a team effort within a research centre such as the Oxford Poverty and Human Development Initiative (OPHI). So we are more than usually grateful for the diligent backstopping by our colleagues as we addressed this book project and they took leadership in other areas.
