My paper, “Cash Transfers and Health: Evidence from Tanzania” (with Holtemeyer & Kosec of IFPRI) has been published in the World Bank Economic Review. The paper is attached. Here is the abstract:
How do cash transfers conditioned on health clinic visits and school attendance impact health-related outcomes? Examining the 2010 randomized introduction of a program in Tanzania, this paper finds nuanced impacts. An initial surge in clinic visits after 1.5 years—due to more visits by those already complying with program health conditions and by non-compliers—disappeared after 2.5 years, largely due to compliers reducing above-minimal visits. The study finds significant increases in take-up of health insurance and the likelihood of seeking treatment when ill. Health improvements were concentrated among children ages 0–5 years rather than the elderly, and took time to materialize; the study finds no improvements after 1.5 years, but 0.76 fewer sick days per month after 2.5 years, suggesting the importance of looking beyond short-term impacts. Reductions in sick days were largest in villages with more baseline health workers per capita, consistent with improvements being sensitive to capacity constraints. These results are robust to adjustments for multiple hypothesis testing.
This is a deep analysis of the health investments and impacts stemming from cash transfers in Tanzania. Here are some other resources from the same experiment:
- An open access working paper version of the attached paper is available here (which is substantively the same as the published version), and a summary blog post is here.
- A broader analysis of program impacts (beyond health) is available here. A quick summary of those results is available here.
- All of the data from the Tanzania community-based conditional cash transfer evaluation are available here.
epidemiology, public health, urban planning, amateur activism, all rolled into a tasty narrative
“You and I may not live to see the day…and my name may be forgotten when it comes; but the time will arrive when great outbreaks of cholera will be things of the past; and it is the knowledge of the way in which the disease is propagated which will cause them to disappear.” (John Snow to Henry Whitehead, p181)
I had heard the story about how John Snow essentially invented epidemiology by tracing cholera deaths to the Broad Street Pump in London, after which he removed the pump handle and the epidemic ended. Johnson shows us that so much more was at work. While John Snow was trying to figure out the source of the epidemic, a local clergyman was doing his own research, and the health board leaders were doing research to support their own – faulty – claims about airborne causes. Johnson demonstrates not only the process of discovery but the challenging politics around trying to convince key leaders to remove the pump handle. Just as interesting are the implications for public health and city planning even up until the present. Johnson creates a very human, passionate narrative around all of this non-fiction, filled with nuggets (as when John Snow administered Queen Elizabeth’s anesthesia for one of her childbirths). I completely recommend this important book: It wasn’t a pure page-turner, but it was interesting and it felt important. Another great public health related book, written for younger readers, is An American Plague: The True and Terrifying Story of the Yellow Fever Epidemic of 1793, by Jim Murphy. Ghost Map captures much more of the interconnectedness of the different sectors of society, though.
I listened to the unabridged audiobook narrated by Alan Sklar. Good narration.
Note on objectionable content: Occasional non-Sunday School language when referring to London’s problem of disposing of human excrement.
Here is an excerpt from the New York Times Sunday Book Review:

Edwin Chadwick…[argued] that delivering fresh feces in an expedient manner to England’s waterways would produce larger fish.
I think the most important element here is that the feces be delivered expediently. From Steven Johnson’s The Ghost Map: The Story of London’s Most Terrifying Epidemic – and How It Changed Science, Cities, and the Modern World, p116
