Economists have
explored the impact of providing households with information on
their water consumption relative to their neighbors, and estimating
the impacts of such social comparisons on water use. Ferraro and Price
(2013) implement a field experiment involving more than 100,000
households served by an Atlanta-area water utility. Their results indi-
cate that social comparisonmessages had a greater influence on behav-
ior (reducing water demand) than simple pro-social messages about
the need to conserve during a dry summer, or technical information
on how water conservation could be accomplished.
