Abstract: In this paper we apply hypothetical choice experiments through a field survey in Shanghai of China to examine whether China Energy Efficiency Label affects consumers f choices of air conditioner and refrigerator. A latent class approach is used to observe both heterogeneities among the respondents and product brands. The results suggest that the effect of energy efficiency label on consumers f preferences is twofold. First, more energy efficient air conditioners or refrigerators are preferred by consumers, no matter whether they are with foreign brands or domestic brands and whether they are new or second-hand. Second, energy efficiency label per se is recognized by consumers. In addition, presence of a (hypothetical) label that indicates the electricity bill fs difference comparing to a standard model is significantly preferred by the respondents in most of the cases, suggesting that more information provided to consumers makes them much happier. Finally, the class probability weighted willingness to pay values for one rank upgrading in energy efficiency of refrigerator are higher than those of air conditioner, implying that consumers have an incentive to pay more for appliances used more frequently.
