Consumer preferences are often influenced by reference-dependent preferences. This study investigates the influence of reference-dependent preferences on the estimation of willingness to pay (WTP) for table grape attributes elicited by a second-price auction. We evaluate two models: the attribute-based reference dependence model, where individuals compare the target product’s attributes with their favorite ones, and the alternative-based reference dependence model, where comparisons are made with a reference product. Results show that including reference points impacts the WTP estimation for different attributes, with varying levels of loss aversion, suggesting the attribute-specific influence of reference points.

It is often assumed that consumers’ willingness to pay (WTP) for eco-labeled products in research settings is not because of a desire for environmental protection, but rather that they are socially compelled to make decisions that reflects favorably on them, limiting the validity of findings. Using a second-price Vickrey experimental auction, this study found higher WTP for an eco-labeled product than a comparable good, but that social desirability bias, measured by the Marlowe–Crowne Social Desirability Scale, was not a significant predictor of WTP. Instead, environmental consciousness, environmental knowledge, education, and available information were stronger predictors of WTP for eco-labeled goods.

The focus of the current study was on the market potential for grass-fed beef in the Appalachian region, given that these products embody observed, experiential, nutritional, and process attributes that may appeal to a large consumer base. An in-store variant of the Becker-DeGroot-Marschack experimental auction mechanism was employed in the region to determine consumer preferences and willingness to pay. A majority of respondents preferred the grass-fed product over conventional grain-fed samples and were willing to pay a price premium to obtain it. Preferences for grass-fed were rooted largely in the associated superior nutritional content and core observed attributes.

Preferences for pomegranates, including some novel pomegranate varieties, were evaluated using an experimental auction and nonhypothetical preference ranking mechanism. Additional information on the taste and health benefits of the products was provided to mimic the information-gathering process on novel products. Product familiarity, product information, and reference prices were key factors in explaining willingness to pay for the included novel products. Results from the auction and nonhypothetical preference ranking procedures were divergent. Furthermore, interactions were detected between information treatments and product characteristics.
