| Resumo: |
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.
