DOI 10.3386/w30816

Issue Date January 2023

New technologies allow perfect detection of environmental violations at near-zero marginal cost, but take-up is low. We conducted a field experiment to evaluate enforcement of water conservation rules with smart meters in Fresno, CA. Households were randomly assigned combinations of enforcement method (automated or in-person inspections) and fines. Automated enforcement increased households’ punishment rates from 0.1 to 14%, decreased summer water use by 3%, and reduced violations by 17%, while higher fine levels had little effect. However, automated enforcement also increased customer complaints by 1,102%, ultimately causing its cancellation and highlighting that political considerations limit technological solutions to enforcement challenges.

To Whom it May Concern,

This letter certifies that this research was conducted with support of the Laura and John Arnold Foundation and the Smith Richardson Foundation. We obtained IRB approval from the University of Chicago. The City of Fresno had the right to review the article before publication, and provided minimal clarifying comments, which we incorporated.

Since I finished working on the pilot study described in this paper, I have worked as a consultant for the Brattle Group in legal matters pertaining to The City of Fresno’s interests in water supplies from the Central Valley Project and from the Kings River. These cases are entirely unrelated to the subject of this paper and have in no way influenced the papers results or findings.

I have no further conflicts of interest in this related to the subject of this paper.

Sincerely,
Oliver Browne
