Abstract: Can a simple point-of-purchase (POP) shelf-label increase sales of organic foods? We use a random-effects, random-coefficients model, including a time adjustment variable, to test data from a natural experiment in a hypermarket in Gävle, Sweden. Our model incorporates both product specific heterogeneity in the effects of labeling and consumer adjustment to the labels over time. The introduction of POP displays was found to lead to an increase in sales of organic coffee and olive oil, but a reduction in sales of organic flour. All targeted products became less price-sensitive. The results reveal that product specific heterogeneity has to be accounted for, and in some cases consumers adjusted to labeling over time.
