In response to increasing customer attention to food attributes, agribusinesses are employing novel product differentiation strategies. As an example, we investigate the use of food safety claims on new packaged food products from the food manufacturersâ€™ perspective. First, using two product innovation databases, we investigate claim use on labels in seven English-speaking countries over the period from 1980 to 2008. Then, based on manufacturer recommended selling prices and using U.S. data (from 2002 to 2008), we apply parametric and nonparametric hedonic methods to identify supply-side (agribusiness) valuations of chemical and microbiological claims in two food categories. We identify a significant 5 cent premium per ounce for a â€œpreservative freeâ€ claim in spoonable yogurts. We do not find a statistically significant impact for â€œE. coli freeâ€ messages on meat and poultry products but find a significant price premium (19.3 cents and 25.7 cents per ounce in the two models) for â€œantibiotic freeâ€ claims in this category.
