Should farmers follow the recommendations of market advisory services? Ahierarchical Bayesian approach to estimation of expected performance

A Bayesian hierarchical approach is employed to estimate individual expected performance of agricultural market advisory services. Skeptical beliefs based on market efficiency are incorporated as prior information. For a skeptical decision maker who is willing to follow an advisory program only if it is expected to increase price received by more than 1%, one of the corn programs, most of the soybean programs, and a few wheat programs may be valuable marketing alternatives. The expectation under this model from following the single top-ranked program are price increases of 1%, 4%, and 3% for corn, soybeans, and wheat, respectively.
