Abstract Rationally inattentive consumers tend to apply simplified heuristics when making decisions. We test the hypothesis of rational inattention in the context of residential water usage where water bills typically account for a small fraction of household expenditures and only attract casual attention. We begin by rigorously testing whether or not residential water customers exhibit evidence of rational inattention. We then propose a heuristic water demand model to explore the decision-making of rationally inattentive consumers and validate the model by comparing the model with the discrete-continuous choice model on attentive and fully informed decision makers in out-of-sample predictions.
