摘要：Past value-added research employs hedonic pricing models to estimate premiums associated withvalue-added feeder cattle characteristics. However, hedonic pricing models require restrictiveassumptions and impose a functional form. Producers also self-select into a treatment group,potentially biasing estimates. Using propensity score matching, we reduce potential bias fromproducer self-selection and from imposing a functional form. Results suggest that hedonicpricing models may be negatively biased in estimates of premiums received by value-added calfproducers. Current adopters receive a premium of $5.38/cwt from participation in a certifiedpreconditioning 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 preconditioningprograms.
