Romanian households could choose schools with one standard deviation worth of additional value added. Why do households leave value added "on the table"? We study two possibilities: (i) information and (ii) preferences for other school traits. In an experiment, we inform randomly selected households about schools' value added. These households choose schools with up to 0.2 standard deviations of additional value added. We then estimate a discrete choice model and show that households have preferences for a variety of school traits. As a result, fully correcting households' beliefs would eliminate at most a quarter of the value added that households leave unexploited.
