Did you find what you wanted?

Five and half years ago, at the end of the spring semester of 2009, I sat down and over the course of 30 days drafted my book Delivering Development. The book was, for me, many things: an effort to impose a sort of narrative on the work I’d been doing for 12 years in Ghana and other parts of Africa; an effort to escape the increasingly claustrophobic confines of academic writing and debates; and an effort to exorcise the growing frustration and isolation I felt as an academic working on international development in a changing climate, but without a meaningful network into any development donors. Most importantly, however, it was a 90,000 word scream at the field that could be summarized in three sentences:
- Most of the time, we have no idea what the global poor are doing or why they are doing it.
- Because of this, most of our projects are designed for what we think is going on, which rarely aligns with reality
- This is why so many development projects fail, and if we keep doing this, the consequences will get dire
The book had a generous reception, received very fair (if sometimes a bit harsh) reviews, and actually sold a decent number of copies (at least by the standards of the modern publishing industry, which was in full collapse by the time the book appeared in January 2011). Maybe most gratifying, I heard from a lot of people who read the book and who heard the message, or for whom the book articulated concerns they had felt in their jobs.
This is not to say the book is without flaws. For example, the second half of the book, the part addressing the implications of being wrong about the global poor, was weaker than the first – and this is very clear to me now, as the former employee of a development donor. Were I writing the book now, I would do practically nothing to the first half, but I would revise several parts of the second half (and the very dated scenarios chapter really needs revision at this point, anyway). But, five and a half years after I drafted it, I can still say one thing clearly.
I WAS RIGHT.
Well, I was right about point #1 above, anyway. The newest World Development Report from the World Bank has empirically demonstrated what was so clear to me and many others, and what I think I did a very nice job of illustrating in Delivering Development: most people engaged in the modern development industry have very little understanding of the lives and thought processes of the global poor, the very people that industry is meant to serve. Chapter 10 is perfectly titled: “The biases of development professionals.” All credit to the authors of the report for finally turning the analytic lens on development itself, as it would have been all too easy to simply talk about the global poor through the lens of perception and bias. And when the report turns to development professionals’ perceptions…for the love of God. Just look at the findings on page 188. No, wait, let me show you some here:
For those who are chart-challenged, let me walk you through this. In three settings, the survey asked development professionals what percentage of their beneficiaries thought “what happens in the future depends on me.” For the bottom third, the professionals assumed very few people would say this. Except that a huge number of very poor people said this, in all settings. In short, the development professionals were totally wrong about what these people thought, which means they don’t understand their mindsets, motivations, etc. Holy crap, folks. This isn’t a near miss. This is I-have-no-idea-what-I-am-talking-about stuff here. These are the error bars on the initial ideas that lead to projects and programs at development donors.
WDR’s frames these findings in pretty stark terms (page 180):
Perhaps the most pressing concern is whether development professionals understand the circumstances in which the beneficiaries of their policies actually live and the beliefs and attitudes that shape their lives.
And their proposed solution is equally pointed (page 190):
For project and program design, development professionals should “eat their own dog food”: that is, they should try to experience firsthand the programs and projects they design.
Yes. Or failing that, they should really start either reading the work of people who can provide that experience for them, or start funding the people who can generate the data that allows for this experience (metaphorically).
On one hand, I am thrilled to see this point in mainstream development conversation. On the other…I said this five years ago, and not that many people cared. Now the World Bank says it…or maybe more to the point, the World Bank says it in terms of behavioral economics, and everyone gets excited. Well, my feelings on this are pretty clear:
- Just putting this in terms of behavioral economics is actually putting the argument out there in the least threatening manner possible, as it is still an argument from economics that preserves that disciplinary perspective’s position of superiority in development
- The things that behavioral economics have been “discovering” about the global poor that anthropology, geography, sociology, and social history have been saying for decades. Further, their analyses generally lack explanatory rigor or anything resembling external validity – see my posts here, here, and here.
Also, the WDR never makes a case for why we should care that we are probably misunderstanding/ misrepresenting the global poor. As a result, this just reads as an extended “oopsie!” piece that needs not be seriously addressed as long as we look a little sheepish – then we can get back to work. But getting this stuff wrong is really, really important – this was the central point of the second half of Delivering Development (a point that Duncan Green unfortunately missed in his review). We can design projects that not only fail to make things better, we can actually make things much worse: we can kill people by accident. We can gum up the global environment, which is not going to only hurt some distant, abstract global poor person – it will hit those in the richest countries, too. We can screw up the global economy, another entity that knows few borders and over which nobody has complete control. This is not “oopsie!” This is a disaster that requires serious attention and redress.
So, good first step World Bank, but not far enough. Delivering Development still goes a lot further than you are willing to now. Delivering Development goes much further than behavioral development economics has gone, or really can go. Time to catch up to the real nature of this problem, and the real challenges it presents. Time to catch up to things I was writing five years ago, before it’s too late.

Comments Off on What behavioral economics isn’t? I’ll tell you what it isn’t…
CGD has an interesting short essay up, written by Matthew Darling, Saugato Datta, and Sendhil Mullainathan, entitled “The Nature of the BEast: What Behavioral Economics Is Not.” The piece aims to dispel a few myths about behavioral economics, while offering a quick summary of what this field is, and what its goals are. I’ve been looking around for a good short primer on BE, and so I had high hopes for this piece…unfortunately, for two reasons the piece did not live up to expectations.
First, the authors tie themselves in a strange knot as they try to argue that behavioral economics is not about controlling behavior. While they note that BE studies and tools could be used to nudge human behavior in particular directions, they argue that “What distinguishes the behavioral toolset [from those of marketers, for example], however, is that so many of the tools are about helping people to make the choices that they themselves want to make.” This claim sidesteps a very important question: how do we know what choices they want to make? What we see as problematic livelihoods outcomes might not, in fact, be all that problematic to those living those outcomes, and indeed might have local rationales that are quite reasonable. While this might seem an obvious point, most BE work that I have seen seems to rest on a near-total lack of understanding of why those under investigation engage in the behaviors that “require explanation”. Therefore, the claim that BE helps people make the choices they want to make is, in fact, rather patriarchal in that the determination of what choices people want to make does not rest with those people, but with the behavioral economist. Sadly, this is a fairly accurate representation of much work done under the heading of BE. It would have been better if the authors had simply pointed out that BE is no more obsessed with incentives than any other part of economics, and if people are worried about behavioral control, they’d best have a look at the US (or their own national) tax code and focus their anxiety there.
Second, the authors argue “Behavioral economics differs from standard economics in that it uses a more realistic (and more complicated) model for people [and their decisions].” Honestly, I have seen no evidence for a coherent model of humans or their behavior in BE. What I have seen is a lot of rigorous data collection, the results of which are then shoehorned into some sort of implicit explanatory framework laden with unexamined assumptions that generally do not hold in the real world. Rigorously identifying when particular stimuli result in different behaviors is not the same thing as explaining how those stimuli bring about those behaviors. BE is rather good at the former, and not very good at all at the latter. The authors are right – we need more realistic and complicated models of human decision-making, and there are some out there (for example, see here and here – email me if you need a copy of either .pdf). BE would do well to actually read something outside of economics if it is serious about this goal. There are a couple of disciplines out there (for example, anthropology, geography, some aspects of sociology and social history) that have long operated with complex framings of human behavior, and have already derived many of the lessons that BE is just now (re)discovering. In this light, then, this short paper does show us what BE isn’t: it isn’t anthropology, geography, or any other social science that has already engaged the same questions as BE, but with more complex framings of human behavior and more rigorous interpretations of observed outcomes. And if it isn’t that, what exactly is the point of this field of inquiry?

While behavioral economics continues to open old questions in development to new scrutiny, I am still having a lot of problems with the very unreflexive approach BE takes toward its own work (see earlier takes on this here and here). Take, for example, Esther Duflo’s recent lectures discussing mistakes the poor make. To discuss the mistakes the poor make, we must first understand what the goals of the poor are. However, I simply don’t see the behavioral economists doing this. There is still a lurking, underlying presumption that in making livelihoods decisions people are trying to maximize income and or the material quality of their lives. This, however, is fundamentally incorrect. In Delivering Development and a number of related publications (for example, here, here, and here) I have laid out how, in the context of livelihoods, material considerations are always bound up in social considerations. If you only evaluate these actions as aimed at material goals, you’ve only got a part of the picture – and not the most important part, in most cases. Instead, what you are left with are a bunch of decisions and outcomes that appear illogical, that can be cast as mistakes. Only most of the time, they are not mistakes – they are conscious choices.
Let me offer an example from Delivering Development and some of my other work – the constraint of women’s farming by their husbands. I have really compelling qualitative evidence from two villages in Ghana’s Central Region that demonstrates that men are constraining their wives’ farm production to the detriment of the overall household income. The chart below shows a plot of the size of a given farm versus its market orientation for the households operating under what I call a “diversified” strategy – where the husband farms for market sale, and the wife for subsistence (a pretty common model in sub-Saharan Africa). As you move up the Y axis, the farm gets more oriented toward market sale (1 on that scale is “eat everything”, 3 is sell and eat equally, and 5 is sell everything). Unsurprisingly, since men’s role requires them to produce for market, the size of their farm has little impact on their orientation. But look at the women’s farms – just a tenth of a hectare produces a marked shift in orientation from subsistence to market production…because women own that surplus beyond subsistence, and sell it. They take the proceeds of these sales, buy small goods, and engage in petty trading, eventually multiplying that small surplus into significant gains in income, nearly equaling their husbands. What is not to like?
Well, from the perspective of those in these villages, here is something: among the Akan, being a “good man” means being in control of the household and out-earning your wife. If you don’t, your fitness as a man gets called into question, which can cost you access to land. For wives, this is bad because they get their land through their husbands. So as a result, being in a household where the woman out-earns her husband is not a viable livelihoods outcome (as far as members of these households are concerned). Even if a man wanted to let his wife earn more money, he would do so at peril of his access to land. So he is not going to do that. What he is going to do is shrink his wife’s farm the next season to ensure she does not out-earn him (and I have three years of data where this is exactly what happens to wives who earn too much). There is a “mistake” here – some of these men underestimated their wives’ production, which is pretty easy to do under rain-fed agriculture in a changing climate. That they are this accurate with regard to land allocation is rather remarkable, really. But the decision to constrain women’s production is not a mistake, per se: it is a choice.
We can agree or disagree with the premises of these choices, and their outcomes, but labeling them as mistakes creates a false sense of simplicity in addressing problematic outcomes – because people only require “correction” to get to the outcomes we all want and need. This, in turn, rests on/reproduces a sense of superiority on the part of the researcher – because s/he knows what is best (see a previous post on this point here). That attitude, applied to the case above, would not result in a productive project design aimed at addressing income or other challenges in these villages.
Yes, people do things against material interest…but there is always a logic behind a decision, and that logic is often deeply entrenched. We would be better off talking about decisions poor people make (for better or worse), and dedicating our time to understanding why they make these decisions before we start deciding who is mistaken, and what to do about it.
I’ve just burned 15,000 words in Third World Quarterly laying out my argument for how to think about livelihoods as more than material outcomes – and how to make that vision implementable, at least via fieldwork that runs in length from days to months. I am happy to send a copy of the preprint to anyone who is interested –and I will post a version to my website shortly.

Just a quick thought, given the interest in my last two posts. I have (obviously) been driven a bit crazy by the RCT/behavioral economics folks who suddenly seem to be coming around to either qualitative methods to explain their results . . . which are generally results that qualitative researchers have known about for a long time. In other words, it seems to me that there is a real danger here that a sort of waving at qualitative methods (i.e. the “bad journalism” approach, where you just do a bunch of interviews without considering who to interview, how to interview them, why interviews vs. focus groups vs. whatever, etc.) might become yet another way to prolong the hegemony of economics over development thinking.
I’m worried about this because while I think economic approaches and theory have purchase on explanation to varying degrees depending on the subject at hand and the scale of analysis, in the end any effort to explain the emergence of and means of addressing a development issue or challenge at a scale that might have meaningful impact that relies on the economic alone will not result in a particularly complete explanation for observed events, nor will it help us understand likely outcome pathways in future similar situations. Put another way, only sometimes can economics get us to a “good enough” solution that enables really productive development work.
What if I told you that I had really good, concrete empirical data from a really tiny dataset (two villages in Ghana, but the entire population of those two villages, so no sampling issues) that clearly demonstrated that any effort to explain livelihoods decision-making in these villages cannot be productively explained by economic approaches – whether crude (i.e. assumptions about maximizing behavior) or complex (game theoretic approaches)? Instead, the data makes it remarkably clear that the economic, while a component of decision-making, is just one component of a project of household governance – it is a clearly external (etic, for you anthro types out there) heuristic that improperly parses the social processes that lead to livelihoods decisions. In short, I can show where the explanatory power of “the economic” stops, and where meaningful explanation requires a re-embedding of the economic in larger social processes that cannot be reduced to the economic (and, at the same time, which demonstrates that the economic cannot be reduced to any of these other processes).
Basically, I’m starting to walk you through my retheorization of livelihoods as what Foucault called governmentality . . . but I could also work this up as a means of discrediting the RCT and behavioral economics turn toward the qualitative by arguing that these efforts are tails wagging the dog . . .
