英文文献摘要：
Consumer willingness to pay for a mandatory country-of-origin labeling program is assessed. A consumer survey was conducted during 2002 in several grocery stores in Boulder, Denver, and Fort Collins, Colorado. Econometric results indicate that surveyed consumers are willing to pay an average of $184 per household annually for a mandatory country-of-origin labeling program. Respondents were also willing to pay an average of $1.53 and $0.70 per pound more for steak and hamburger labeled as "U.S. Certified Steak" and "U.S. Certified Hamburger," which is equivalent to a 38% and 58%, respectively, over the initial given price.
