Revealed preference theory offers a criterion for decision-making quality: if decisions are high quality then there exists a utility function that the choices maximize. We conduct a large-scale field experiment that enables us to test subjects' choices for consistency with utility maximization...

Imperfect information and inattention to energy costs are important potential justifications for energy efficiency standards and subsidies. We evaluate these policies in the lightbulb market using a theoretical model and two randomized experiments. We derive welfare effects as functions of...

This review paper provides an overview of the application of behavioral public economics to energy efficiency. I document policymakers' arguments for "paternalistic" energy efficiency policies, formalize with a simple model of misoptimizing consumers, review and critique empirical evidence, and...

Projection bias is the tendency to overpredict the degree to which one's future tastes will resemble one's current tastes. We test for evidence of projection bias in two of the largest and most important consumer markets - the car and housing markets. Using data for more than forty million...

We formulate a test of the fungibility of money based on parallel shifts in the prices of different quality grades of a commodity. We embed the test in a discrete-choice model of product quality choice and estimate the model using panel microdata on gasoline purchases. We find that when gasoline...

This paper provides evidence concerning the extent to which consumers of liquor employ precommitment devices. One widely recommended precommitment strategy is to regulate alcohol consumption by deliberately manipulating availability. We assess the prevalence of the "availability strategy" by...

We investigate whether the first digit of an odometer reading is more salient to consumers than subsequent digits. We find that retail transaction prices and volumes of used vehicles drop discontinuously at 10,000-mile odometer thresholds, echoing effects found in the wholesale market by...

Financially constrained borrowers have the incentive to influence the appraisal process in order to increase borrowing or reduce the interest rate. We document that the average valuation bias for residential refinance transactions is above 5%. The bias is larger for highly leveraged...

We study the effects of receipts that include personalized ordering suggestions designed to reduce fat and calorie consumption on purchasing behavior at a restaurant chain. We find that customers, in the aggregate, made most of the item substitutions that were encouraged by the messages, such as...

We test the effectiveness of self-help peer groups as a commitment device for precautionary savings, through two randomized field experiments among 2,687 microentrepreneurs in Chile. The first experiment finds that self-help peer groups are a powerful tool to increase savings (the number of...
