U.S. consumers see retail beef products with “no added hormones” (NAH) labels. However, similar labels appear on pork and chicken products, even though hormone use in their production is prohibited. This study assesses consumer perceptions of hormone use in different livestock species. Using choice experiment data, we then examine the impact of these perceptions on preferences for unlabeled meat products and willingness to pay for NAH-labeled meat products. Results suggest that consumer perceptions of hormone use in production are incorrect. Further, perceptions influence consumer preferences and willingness to pay for unlabeled products versus those with NAH labels.

Past value-added research employs hedonic pricing models to estimate premiums associated with value-added feeder cattle characteristics. However, hedonic pricing models require restrictive assumptions and impose a functional form. Producers also self-select into a treatment group, potentially biasing estimates. Using propensity score matching, we reduce potential bias from producer self-selection and from imposing a functional form. Results suggest that hedonic pricing models may be negatively biased in estimates of premiums received by value-added calf producers. Current adopters receive a premium of $5.38/cwt from participation in a certified preconditioning program, while nonadopters would realize $5.17/cwt by adopting certification. Hedonic model values range from $0.52/cwt to $4.32/cwt, for similar or identical preconditioning programs.

Many value-added practices cannot be observed by feeder cattle buyers. Third-party verification can decrease market inefficiency associated with this asymmetric information. We evaluate the effectiveness of a verification program, the Oklahoma Quality Beef Network, in increasing received prices. We estimate the value of verification, weaning, vaccinating, certification and phenotypic traits of feeder cattle at Oklahoma auctions. Results indicate that the OQBN program adds $2.39 to $5.74/cwt. Vaccinating calves adds $1.44/cwt, and weaning calves adds $2.05/cwt. Differential values for lot size, average weight, hide color, frame size, conditioning, Brahman influence, gender and other characteristics are also reported.
