The Economic Lives of the Poor

The Economic Lives of the Poor is a 2007 paper by 2019 Nobel Laureates[1] Abhijit Banerjee and Esther Duflo. It describes results from household surveys of the poor (less than $2.16 a day in 1993 PPP dollars) and extremely poor (less than $1.08 a day in 1993 PPP dollars) conducted in Cote d’Ivoire, Guatemala, India, Indonesia, Mexico, Nicaragua, Pakistan, Panama, Papua New Guinea, Peru, South Africa, Tanzania, and Timor Leste (East Timor). What follows is a condensation of that paper highlighting the most important and striking claims. I focus on the descriptive part of the paper and omit the second part of the paper investigating some concomitant economic puzzles.

Living arrangements

Extended families are common among the extremely poor with the median household containing between seven and eight members. The population tends to be young with only about one quarter as many over 51s as 21--50s (In the U.S., the ratio is 0.6 rather than ~0.25.).


Food and other consumption purchases

Food expenditures typically represent between one half and three quarters of the budget.[2] Expenditure on alcohol and tobacco ranges from about 1 percent to about 8 percent. The median extremely poor household in Udaipur spent 10 percent of its budget on festivals, but expenditure on movies, theater and shows is less than 1 percent.

Ownership of assets

Land ownership among the extremely poor ranges from 4 percent in Mexico to 99 percent in Udaipur. However, the owned plots are often small---less than three hectares---and of poor quality.

"In Udaipur, where we have detailed asset data, most extremely poor households have a bed or a cot, but only about 10 percent have a chair or a stool and 5 percent have a table. [...] No one has a phone."

Health and well-being

The bottom decile of income in an Indian survey sample averages 1400 calories a day. Sixty-five percent of poor adults in Udaipur have a BMI that classifies them as underweight and 55 percent are anemic.

Between 11 and 46 percent (depending on the country) of the extremely poor report having been bedridden for at least one day in the the last month.

"While the poor certainly feel poor, their levels of self-reported happiness or self-reported health levels are not particularly low (Banerjee, Duflo, and Deaton, 2004). On the other hand, the poor do report being under a great deal of stress, both financial and psychological."

Investment in education

Education expenditure is generally quite low because primary schooling is often free. In 12 of the 13 countries examined, at least 50 percent of extremely poor children (ages 7 to 12) are in school.


Day labor, self-employment in agriculture and small-scale non-agricultural entrepreneurship are each common. In fact, many of the poor have multiple occupations (possibly a form of risk spreading).

"Strikingly, almost 10 percent of the time of the average household [surveyed in West Bengal] is spent on gathering fuel, either for use at home or for sale."



From 11 to 93 percent (depending on the country) of rural, extremely poor households have outstanding debt. The credit is usually from informal sources and the interest is generally above 3 percent per month. High interest reflects high enforcement cost rather than high risk of default.


Savings accounts are generally uncommon. Microcredit may serve as a rough substitute with the benefit of an external enforcer (i.e. the creditor demands repayment which may be easier than forcing yourself to save).


Less than 6 percent of the extremely poor are covered by health insurance. In principle, community members can informally insure each other for a variety of risks but this works best for idiosyncratic risks and not for, for example, a village-wide drought.


Though land ownership is relatively common, records of ownership are less common. This makes sale or mortgage difficult. Often the poor work land owned by others which reduces incentives for best effort.


"The availability of physical infrastructure to the poor like electricity, tap water, and even basic sanitation (like access to a latrine) varies enormously across countries. In our sample of 13 countries, the number of rural poor households with access to tap water varies from none in Udaipur to 36 percent in Guatemala. The availability of electricity varies from 1.3 percent in Tanzania to 99 percent in Mexico. The availability of a latrine varies from none in Udaipur to 100 percent in Nicaragua. Different kinds of infrastructure do not always appear together."

The quality of health facilities for the poor tends to be low with health workers in one sample absent 35 percent of the time. In one study, an expert panel found that the average treatment suggested by a health provider in their sample was more likely to do harm than good. Infant mortality among the rural, extremely poor ranges from 3.4 percent in Indonesia to 16.7 percent in Pakistan.

Educational facilities are similarly lacking. Teachers in one sample were found to be absent 19 percent of the time. A nationwide survey in India found that 22 percent of sixth to eighth grade children cannot read a second-grade text while 65.5 percent of children ages 7 to 14 can't do division.

A nice, similar writeup along these lines is the book Portfolios of the Poor. Check it out if you want to go a bit more in-depth specifically on finances and how they affect daily life.

+1 to this, I definitely found Portfolios of the Poor a great way of actually understanding the lives of the globally poor

Very helpful summary, thanks

Next time can you submit this as a linkpost to your blogpost? When that happens we tell Google that your blogpage is the "canonical link". As it is, Google thinks we might be stealing your content and slightly decrements our search rankings.

Oh, sure. Are there any other differences between how link posts and regular posts are treated?

It'll have [Link] automatically added to the title, and the link will appear in italicized text at the top. Not sure that's exhaustive.

Okay, thanks. I can imagine it being useful to show the canonical link tip somewhere during the posting flow? This problem seems pretty common e.g. Interview with Owen Cotton-Barratt on Productivity also. For what it's worth, my initial understanding was that a link post was for when the linked material was the main content of interest and the text accompanying the link here was for commentary, discussion or summary of the linked content.

Thank you for posting this. It's an excellent summary and also brought to my attention an important article I otherwise might not have come across for months.
