In many societies, social norms create common property rights in natural resources, limiting incentives for private investment. This paper uses a randomized evaluation in Kenya to measure the health impacts of investments to improve source water quality through spring protection, estimate the value that households place on spring protection, and simulate the welfare impacts of alternative water property rights norms and institutions, including common property, freehold private property, and alternative “Lockean” property rights norms.

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...
