摘要：By conducting a meta-analysis using 50 observations collected from 15 primary studies, we systematically analyze heterogeneities in consumer preferences for U.S. beef products and the results have valuable implications both from a policy perspective as well as from a methodological perspective. The main findings include that consumers in European and Asian countries are willing to pay less for U.S. beef products than those in North American countries and that the BSE incidence in the U.S. substantially damaged consumer preferences for U.S. beef products outside the U.S. but not in the U.S. The results with respect to methodological heterogeneities also indicate that choice experiments yield higher WTP values and that the sample size is negatively correlated with WTP values.
