We find that infrastructure investments reduce fecal contamination by 66% at naturally occurring springs, cutting child diarrhea by one quarter. While households increase their use of protected springs, travel-cost based revealed preference estimates of ho...

To better understand what might drive these results, we turn to national employment and household consumption and expenditure surveys from Mexico. There are four important findings from the country case study: (1) the majority of the poorest co...
