ACKNOWLEDGMENTS
Dean’s Acknowledgements
I found writing the acknowledgments very challenging. How do you really express how grateful you are, without sounding soppy or saccharine? I am grateful to many, to those who have worked with me, advised me, worked for me, and those who had nothing to do with me but produced great work that we can write about here.
Professionally, I thank my advisers for life, Esther Duflo and Abhijit Banerjee. Their leadership on the founding board of Innovations for Poverty Action and in creating the Jameel Poverty Action Lab has changed the world for the better, and I’m forever proud to be their advisee. Sendhil Mullainathan was both my adviser and now coauthor, and one of the most fun and creative people around. His influence on this book, and me, is throughout. I thank Richard Thaler, for introducing me to behavioral economics when getting my MBA, taking me on as an advisee from afar when I continued on for my Ph.D., and last but not least, providing so much of the motivation behind the work here. I thank Michael Kremer for advising me in my early days of graduate school, including one particularly memorable (for me) coffee when I was first thinking about running experiments to tackle empirical challenges, and for his leadership in starting up randomized trials in the pre-IPA and pre-JPAL days. I thank Jonathan Morduch, for guiding me and teaching me so much about the economics and politics of microfinance. And lastly, only chronologically, I thank Chris Udry. Esther told me one day in graduate school to get on a train and go visit Chris for a few hours in New Haven, and Chris was gracious enough to meet me even though I wasn’t a student at Yale. Hard to say of course (I have no control group “me” who didn’t get on the train!), but I think that train ride made a huge impact on my life. A great example of Esther’s stellar life-changing advice. Thank you, Esther (and Chris) .
Jonathan Zinman is a unique force in my life, both as a brother and my most common collaborator. It is trite but true to say that the research here that I have done with him would not have been done, or would not have been done as well, were it not for him. Although less frequent in my collaboration, I am grateful to my other collaborators in development projects talked about in this book: Nava Ashraf, Marianne Bertrand, Miriam Bruhn, Xavier Giné, Maggie McConnell, Jonathan Morduch, Antoinette Schoar, Eldar Shafir, Martín Valdivia, and Wesley Yin.
I cannot thank enough the team at Innovations for Poverty Action and the Jameel Poverty Action Lab. The current leadership team at IPA—Annie Duflo, Kathleen Viery, and Delia Welsh—helps me sleep a few hours each night, and helps IPA grow twofold year-in and year-out. Our staff on the ground are some of the hardest working, most dedicated, and smartest individuals. They come at this with different motivations and paths, and it is always an absolute pleasure and thrill to work with each of them. Without them none of this would be possible. Wendy Lewis has provided me and IPA the support these past few years to keep it all straight and orderly—thank you.
This leads me to the next group: the academics. I am just one of many on this quest. I thank the field researchers whose work I discuss in this book for generating the knowledge I’m able to discuss here: Abhijit Banerjee, Stefano Bertozzi, Suresh de Mel, Esther Duflo, Pascaline Dupas, Paul Gertler, Xavier Giné, Rachel Glennerster, Robert Jensen, Cynthia Kinnan, Michael Kremer, David McKenzie, Edward Miguel, Clair Null, Jonathan Robinson, Emmanuel Saez, Manisha Shah, Rebecca Thornton, Chris Woodruff, Dean Yang, Alix Zwane.
I thank the people who have been on the board of Innovations for Poverty Action: my advisers Esther, Abhijit, and Sendhil, and Ray Fisman, for agreeing to be on the board when their crazy fresh-out-of-graduate school advisee thought creating such an organization would be a good idea (rather than the more sensible focus-on-your-research-only strategy of an untenured professor). And I thank the current board—Greg Fischer, Jerry McConnell, Paras Mehta, Jodi Nelson, J. J. Prescott, Steve Toben, and Kentaro Toyama for carrying the torch and providing the leadership and guidance IPA needs to take us to the next level—as well as three former board members, Wendy Abt, Ruth Levine, and Alix Zwane, for being on the board during our critical growth over the past few years.
The organizations we have worked with deserve particular recognition. Although some of the research here is not testing the core mission of an organization, some of it is. There is nothing more impressive than someone so dedicated to poverty that they are willing to put their beliefs and hopes aside and ask for the evidence, even if it goes against what they have been saying they think should be done. More donors should reward failure. The organizations behind the work reported in this book are all exemplary groups willing to put it all out there in their strive for improvement. For my research projects discussed in this book, I’ve had the pleasure of working with Omar Andaya, Gerald Andaya, Jonathan Campaigne, Chris Dunford, Bobbi Gray, Mandred Kuhn, Iris Lanao,
Reggie Ocampo, and John Owens. I thank them for their dedication to learning what works.
My favorite times in the field are when my family joins me. It is a true blessing to not have to choose between work and family. Although I like to think my family has gotten a lot out of the experience (they say they have!), I know I’m clearly the one who benefits the most. I get to do my work without having to sacrifice one tiny bit. But this wouldn’t be possible if Cindy weren’t so flexible and supportive, and our kids weren’t such great travelers: able to have fun anywhere, ride on long rickety drives through Ghana, sleep in bedbug-ridden cots in rural Mali, and learn to eat just about anything (enjoying the good food and merely laughing about the bad).
I recently read the acknowledgments in my dissertation and was struck by my closing thanks, and how something so true then could be even more true now. So I repeat them word for word (except now with Gabi added, as she was not born until after graduate school): “Most of all, I thank my family: my wife, Cindy, my son, Maxwell, my daughter Maya and one daughter to be named soon [Gabi]. Having Cindy and Max and Maya [and Gabi] with me on my research travels made all the difference for getting these projects done. I would not be a development economist if it were not for Cindy’s support, flexibility, and enthusiasm. . . . This [book] is dedicated to my wife, best friend and love of my life, Cindy, and to Maxwell and Maya [and Gabi].”
Jake’s Acknowledgements
Traveling to the field to visit project sites throughout 2009 was a thrill and an adventure and an absolute hoot, and would have been impossible were it not for the help, hospitality, enthusiasm, and heroics of dozens of people.
First and foremost there are the men and women who shared their time and their experiences with me—including, but not limited to, the people whose stories were featured throughout the book. Almost without exception, these were folks who, unsolicited and with no promise of compensation, dropped whatever they were doing to welcome a complete stranger and make him feel at home. I am grateful for their kindness and was humbled by their generosity more times than I can count. Thank you.
I would never have met those extraordinary people, though, had it not been for the efforts of researchers and partner organization staff, who hosted, guided, translated, planned, recommended, coordinated, and generally went above and beyond in service of this project. In India, thanks to Justin Oliver and Joy Miller, the entire CMF team, Selvan Kumar, Nilesh Fernando, Abhay Agarwal, Sree Mathy, Jyothi, and Srikumar Ramakrishnan. In Peru, thanks to Tania Alfonso, David Bullon-Patton, Wilbert Alex Yanqui Arizabal, Silvia Robles, and Kartik Akileswaran. In Bolivia, thanks to Doug Parkerson, Martin Rotemberg, Maria Esther, and Chris from Minuteman Pizza in Uyuni. In Uganda, thanks to Pia Raffler, Sarah Kabay, Becca Furst-Nichols, and William Bamusute. In Kenya, thanks to Karen Levy, Andrew Fischer Lees, Jeff Berens, Owen Ozier, Jinu Koola, Blastus Bwire, Leonard Bukeke, Grace Makana, Moses Baraza, and Adina Rom. In Malawi, thanks to Niall Keheler, Jessica Goldberg, Lutamyo Mwamlina, Cuthbert Mambo, and Mr. Phiri of MRFC. In the Philippines, thanks to Rebecca Hughes, Megan McGuire, Nancy Hite, Yaying Yu, Ann Mayuga, Mario Portugal, Primo Obsequio, Alex Bartik, and Adam Zucker. In Colombia, thanks to Angela Garcia Vargas.
Thanks to the indomitable Wendy Lewis and everyone at IPA, both in New Haven and abroad, for invaluable support throughout.
Thanks to everybody who read and commented on drafts, who brainstormed, and who helped talk through ideas. Thanks especially to Laura Fillmore for valuable discussions at every stage of the process. Thanks to Helen Markinson for all the encouragement. Thanks to Chelsea DuBois for supplying the opening story and much, much more besides.
Finally, infinite thanks to Mom, Dad, Naomi, and Julie, who are without a doubt the best people I know.
Dean and Jake’s Collective Acknowledgements
We thank our agent, Jim Levine, who swore when we signed with him that he wasn’t a sign-and-leave kind of agent. Trust him we did, and he came through, working with us on the manuscript (and title—that was hard!) all the way to the end. We thank Jim’s team at Levine Greenberg for all of their work along the way, including Elizabeth Fisher, Sasha Raskin, and Kerry Sparks. We thank our editor, Stephen Morrow at Dutton, Penguin Books, for his valuable insights and edits and guidance throughout, and patience as we rejected title after title after title. We thank Andrew Wright for valuable input, both substantive and stylistic.
We are grateful to many for reading draft (and often draft after draft) of the manuscript, including David Appel, Julie Appel, Naomi Appel, Scott Bernstein, Kelly Bidwell, Laura Fellman, Erica Field, Laura Fillmore, Sally Fillmore, Alissa Fishbane, Nathanael Goldberg, Cindy Karlan, Karen Levy, David McKenzie, Ted Miguel, Cleo O’Brien-Udry, Tim Ogden Rohini Pande, Jonathan Robinson, Richard Thaler, Rebecca Thornton, and Chris Udry.
