The positive effects of improved sanitation in India

From a paper by Dean Spears Sneha Lamba on a sanitation campaign in India 
The abstract 
Early life health and net nutrition shape childhood and adult cognitive skills and human capital. In poor countries -- and especially in South Asia -- widespread open defecation without making use of a toilet orlatrine is an important source of childhood disease. This paper studies the effects on childhood cognitive achievement of early life exposure to India's Total Sanitation Campaign, a large government program that encouraged local governments to build and promote use of inexpensive pit latrines. In the early years of the program studied here, the TSC caused six-year-olds exposed to it in their first year of life to be more likely to recognize letters and simple numbers. The results suggest both that open defecation is an important threat to the human capital of the Indian labor force, and that a program feasible to low capacity governments in developing countries could improve average cognitive skills.
From the conclusions
Our findings suggest that even a low capacity government can implement a relatively inexpensive program that will cause an important improvement in cognitive skills, given the context of widespread open defecation. The program we study was imperfect: much open defecation remains even after the end of a decade of the TSC. However, open defecation may be so harmful for early-life physical and cognitive development that even an imperfect and incomplete improvement in sanitation can have important effects.
