This meta-analysis provides a consensus on the willingness to pay (WTP) for organic food, and the factors influencing its premium. It includes 56 studies which satisfy the criteria established by its protocol, contributing to 108 observations. Results show that, on average, consumers worldwide are willing to pay a 60% premium for the organic attribute. Premiums have increased over the years and are larger for relatively cheaper products in Asia and Africa. Education level has an inverse relationship with the extra amount consumers would pay for organic and is a pivotal variable in WTP estimates. However, premia are also highly influenced by the methodology applied in the study, indicating that stated preference approaches on average increase estimates by 55%, though the treatment of hypothetical bias mitigates most of this, with an effect of -43%. Face-to-face surveys and information given during the survey also positively affect premiums. Thus, these should be considered when eliciting WTP estimates.
