This research 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 both experimental auction and contingent valuation method (CVM) to investigate factors that affect the consumer’s...

This paper illustrates the importance of consumer segments for the estimation of the distribution of sample willingness to pay. We find evidence that those who prefer non-GM have a different marginal utility of income and that naïve pooling of consumer segments may yield a misleading...
