| Hypothetical bias is a persistent problem in stated preference studies. We propose and test a method for reducing hypothetical bias based on the cognitive dissonance literature in social psychology. A central element of this literature is that people prefer not to take inconsistent stands and will change their attitudes and behavior to make them consistent. We find that participants in a stated preference willingness-to-pay study, when told that a nonhypothetical study of similar goods would follow, state significantly lower willingness to pay than participants not so informed. In other words, participants adjust their stated willingness to pay to avoid cognitive dissonance from taking inconsistent stands on their willingness to pay for the good being... |

| Organic producers have limited methods of avoiding plant diseases that result in cosmetic damage to produce. Therefore, the appearance of organic produce is often less than perfect. We use an experimental auction to investigate how cosmetic damage affects consumers' willingness to pay for organic apples. We find that 75% of the participants are willing to pay more for organic than for conventional apples given identical appearance. However, at the first sight of any imperfection in the appearance of the organic apples, this segment is significantly reduced. Furthermore, we find that there is a significant effect of interaction between cosmetic damage and product methods. Even though most consumers say they buy organic products to avoid pesticides, we find... |

| We conduct a within-sample test of hypothetical bias and parameter equality between a hypothetical stated choice (SC) experiment using pictures and a real choice (RC) experiments using products. With exception of the none-of-these alternative-specific dummy, we cannot reject parameter equality between the two datasets. However, when we estimate the models separately with no parameter restrictions, the SC experiment gave WTP estimates that were approximately 50 percent higher and marginal WTP estimates that were almost two times as high as the corresponding estimates from the RC experiment. However, even though the monetary value of the WTP disparity was large, the disparity between the WTP estimates from the two data sets was not statistically significant. |

| Experimental auctions (X) use real economic incentives but are limited by available products and locally recruited samples. Stated choice (SC) surveys can use a representative sample to estimate the willingness to pay (WTP) for hypothetical products with unavailable characteristics. However, a number of studies conclude that surveys give biased WTP estimates. We designed a method, SC-X, to calibrate the WTP estimates from stated choice surveys with WTP observed in experimental auctions. This method allows us to extend the results from auctions to products with unavailable characteristics and to socioeconomic groups not included in the auction. The SC-X method is illustrated using Norwegian consumers' preferences for country-of-origin and hormone... |

| Vickrey auctions are commonly used to elicit willingness to pay for new food products. This paper shows that in a multi-period context, it can be optimal to bid higher than the expected consumption value for new experience goods to obtain information about the quality of the goods. The degree of value uncertainty, the purchasing frequency, and expected future market prices affect both the expected value of the quality information and the weakly dominant bidding strategy in Vickrey auctions for new experience goods. Keywords: experience goods, value of information, Vickrey auctions. |
