演講摘要 : This study is aimed at investigating the consumer’s preference for food produced in Taiwan and the economic benefits for the country of origin labeling. The study uses data from experimental auction and contingent valuation method (CVM) to estimate factors that affect the consumer’s willingness to pay (WTP) for products under country-of-origin labeling (COOL). The results show that the estimated WTP for the premiums for preserved olives and oolong tea produced in Taiwan are more than 50% over the alternatives from China or Vietnam. Based on the auction data, Tobit models shows that the estimated premiums are 58.1%, 78.2% and 98.1% for Taiwan products over their alternatives of China olives, China oolong tea and Vietnam oolong tea, respectively. Base on the contingent valuation method (CVM), the estimated premiums for Taiwan over China olives from a Logit model is 67%, and the estimated premiums for Taiwan produced oolong tea from a Multinomial Logit model lie between 50% to unknown upper bound over China and Vietnam alternatives. The study demonstrates the superiority of the experimental auction over the CVM. It is also concluded that enacting a COOL law would increase economic benefits to consumers in Taiwan.
