Information Provision and Consumer Behavior: A Natural Experiment in Billing Frequency

Dec 28, 2016 | Casey J. Wichman


In this study, I estimate a causal eff ect of increased billing frequency on consumer behavior. I exploit a natural experiment in which residential water customers switched exogenously from bimonthly to monthly billing. Customers increase consumption by 3.5-5 percent in response to more frequent information. This result is reconciled in models of price and quantity uncertainty, where increases in billing frequency reduce the distortion in consumer perceptions. Using treatment eff ects as sufficient statistics, I calculate consumer welfare gains equivalent to 0.5-1 percent of annual water expenditures. Heterogeneous treatment eff ects suggest increases in outdoor water use.
