چکیده
Little research has been dedicated to examine the effect of expert opinion on consumer demand for goods with credence attributes. Taking advantage of a natural experiment, we use differencein-differences approach to estimate the effect of the NuVal score, an expert opinion of the healthfulness of the food product, on consumer demand. Our results show that posting the NuVal score increases yogurt sales and the effect is larger for products with higher scores. This implies that experts are opinion influencers. Consumers respond positively to the better-nutrition signals provided by the NuVal score. The publicity effect of the new label is also at work.
