A researcher is interested in studying the effect of safe water on child mortality. She uses the clean water program, Programa de Agua Limpia (PAL), to study this issue. PAL was launched in Mexico in 1991, following a sudden emergence of cholera in Central America. Some towns were given access to PAL funds to chlorinate the water. Other towns did not receive those funds. The allocation of funds was not random. For each town in Mexico, the researcher compiles the Child Mortality Rate (per 1,000 children), CMR, for the period 1985-1990 and the mortality rate for the period 1991-1996 and sets up a difference in difference regression. In this regression, each town (indexed by i ) is observed twiceonce before and once after PAL is introduced. Let Aftert be an indicator variable equal to 1 if the observation corresponds to the period 1991-1996. Let PALi be a dummy variable equal to 1 if the observation corresponds to a town that received PAL funds. CMRit= 2.23 – 0.42 Aftert + 0.32 PALi  1.43 Aftert * PALi + eit A researcher is interested in studying the effect of safe water on child mortality.
