This paper evaluates the impact of access to groundwater on poverty using data from rural India. The estimation exploits the fact that the technology required to access groundwater changes exogenously due to constraints imposed by laws of physics at a depth of eight meters. I find that rural poverty in areas where depth from surface is below the cutoff is 9 to10 percent higher. Using survey dat...

I test the pre...
