Is it Right to Have the Poor Pay?

As someone involved in companies that are based on the idea of attacking global problems of pollution and health, I am deeply interested in the issue of whether it is "right" to have the poor pay for products. And I have spent much time trying to find innovative business models that create societal value and allocate it between customers, communities, investors and employees in a way that makes impactful solutions scaleable and sustainable.

In addition to my teaching, I have been quite involved in two companies that are based on the principle that the best way to achieve social good is through market based approaches. Envirofit, which designs, manufactures and sells cook stoves to poor people in India is a non-profit company, dedicated to developing environmentally friendly products so that poor people can lead healthier and more productive lives. Inviragen is a for-profit biotech company developing vaccinces for developing world infectious diseases in markets that traditional pharmaceutical company R&D has ignored. Is this the "right" approach to tackling these global challenges?

Some people have objected that it isn't "right" to have the poor pay for products and services on ethical grounds. They argue that for those who are wealthy to charge someone who is poor violates an ethical norm. That humans should provide charity for religous or altruistic reasons.

More recently, people have started to argue that having the poor pay isn't "right" because it violates rules of economic incentives. That, as Rachel Glennerster of MIT's Jameel Poverty Action Lab (J-PAL)* states in this month's Fast Company: "Charging small amounts is the exact wrong thing to do" to tackle issues facing the poor.

The data are several years old, as is the debate (I first blogged on it in March 2008). But with J-PAL now being featured in Fast Company, and one of its members, Esther Duflo recently being awarded a MacArthur "genius" grant, I am concerned about the ramifications of these catchy sound bites.

J-PAL studies are useful for what they show, but my concern is that their findings are now being applied with too broad a brush. Glennerster's comment is such an example. Perhaps she added caveats to her statement that didn't make it past the Fast Company editor's desk. Both examples are in the field of public health, an area where the societal and community effects are compelling for broad measures. But standing alone, the statement is dangerously overbroad.

As one J-PAL researcher put it in the Fast Company article, "it's more satisfying to answer small questions well than big questions badly." Yet statements such as Glennerster's seem to indicate a willingness to answer the bigger questions with limited data. While most of J-PAL's studies seem to be on government funded aid programs (see Duflo's suggested "Best Buys" to achieve UN Millennium Development Goals), their broader policy prescriptions don't seem to have boundaries. To apply this "pricing model" to the many social enterprises working today in Base of Pyramid markets would be foolish. Not only is it OK to have the poor pay for goods and services, it may often be necessary in order to have these goods and services exist.

To me, Glennerster's comment speaks to only one side of the equation, that of demand. Yes, people will use more mosquito nets if they are free, or get more infants vaccinated if they receive lentils. But that assumes that someone is willing to supply the nets for free, or buy the lentils to accompany the vaccines. In a small trial, this charity work can be done. The sponsor can buy a few kilos of lentils along with the vaccines. But at the massive scale required to really solve some of these problems, I am skeptical. Even the Gates Foundation with its billions cannot buy all the nets, vaccines, cook stoves, treadle pumps and school fees required to lift the world from poverty. With or without lentils. To use the fashionable term these days- charity doesn't "scale." What does scale is markets (and economists know this, don't they?). That is what has made the 4 C's ubiquitous in our world: Coke, condoms, cigarettes and cell phones. While I don't view markets as a panacea for every global challenge, I do think they are indispensable in development.

As my regular readers know, my argument is more nuanced. In some areas, where the problems are of a crisis nature, and governments are weak, charity is the most workable business model. Where problems are more chronic, such as vaccinations or education, but governments are weak and therefore unable or unwilling to provide such public goods, then enterprising, market based approaches offer a more sustainable business model. And these are typically driven by customers paying for their goods and services. Sometimes, the business model is purely commercial. Sometimes, as with Envirofit or International Development Entrprises, it is a hybrid, where donations are used to subsidize product or market development. Other enterprises which have the poor pay include Vision Spring, Grameen Bank, and Kickstart. Even A-Z Textiles, a mosquito net manufacturer. When J-PAL argues that incentives work for the poor, they also need to remember that incentives work for producers. Yet they are curiously silent on who will make the free or subsidized goods and services to support the policies they propose.

To be sure, the actions of A-Z, Vision Spring, or even Grameen Bank are still small. I don't claim that there is any one path to reducing poverty and improving public health, education and the environment. Charity and "free" products will be required in some instances, but so will having the poor pay.

While I am pleased that J-PAL is bringing new approaches and insights to the field of international development, I encourage them to remember that the field has humbled many with big new ideas. Most tools are useful only in specific situations, even economic tools (like randomized trials). To dispel myths is important work, but broad statements of general application begin to build new myths that may be just as mistaken.

The title to this post is purposely provocative. My answer would be "much of the time, but not always." Not a very good sound bite for a reporter. But it sounds "right" to me.

*NOTE: I have recommended J-PAL's work to BOPreneurs. And I found one of their recent studies on the impacts of microfinance to be useful for some of my work in that field.

Update 11-30: NextBillion's Francisco Noguera posted on the Fast Company article and this post. Thank you to those who have commented on this post and for providing more examples. Also, William Easterly recently blogged on another aspect of randomized controlled trials, noting they will "only EVER be available for a small sample of aid projects."

I am certainly with your argument. This has been proven a number of times that free distribution and direct subsidy based models would have negative ramification in sustaining any effort. India has been witnessing the initiatives on smokeless stoves since 60’s perhaps. But Envirofit’s approach has proved that poor are keen to pay for a product which attains the basic requirements of a poor housewife. A market led approach with developmental goals should be the approach. I am also bit apprehensive on the long run ramification of J-PAL’s approach. India which is changing rapidly has been going through many BoP initiatives where poor not only pay but also play a critical role in innovative business solutions. I believe poor, in the new paradigm, is not going to be a mere receiver of free products and services, rather he/she wants to be the stakeholders of the new solutions. Experiments in health, water, finance, energy, agriculture etc. have definitely shown positive direction.

I am a big believer in projects that provide an income to BOP personnel such as the UN FAO West Bengal India success. See “A Backyard Poultry Value Chain Increases Assets, Income and Nutrition” which can be found at http://sapplpp.org/goodpractices/small-holder-poultry/resolveuid/91b5e80af8e97248aff0138f168d083a and at http://zunia.org/index.php?id=11728&tx_dgcontent_pi1[tt_news]=287929&cHash=82cbb42aea. The BOP personnel should be given the opportunity to determine the best products to buy since they know what they need most.
Other projects that provide income are the distribution of seeds by ECHO and the Gates Foundation PASS program. I am supplying moringa and tropical fruit tree seeds in rural Colombia so that 500,000 BOP personnle can improve their living standards.

I read the J-PAL article before finishing your blog, and I appreciate your response. You raised some of the same issues I considered as I read the piece.

Dear Paul, I agree with you as my take on this matter is simple. "If the horse is thirsty you won't need to take him to the water, he'll get there". Any model that aims at making it easy to access the products or services will become sustainable with incentives to all involved. Removing the 'price' shifts the balance. 'No pay' can at best be used tactically to overcome adoptions or trials but it simply won't work unless it's a 'choice' to be made. And who says payment's gottabe in money. History is replete with successes of 'braters'. In India the "avadhi / Lucknowi" cusine evolved from the food-for work during famines in that region in the 18th century. There is a full-fledged economy which has survived through centuries based on a simple barter system.
