Used in a laboratory or survey setting, the declarative methods are very widely used to estimate the consumers preferences. The experimental economic incentive methods allows to make up for hypothetical bias which can affect purely declarative methods. This work sets out several experiments based on methodological comparisons allowing to test the inter-methods validity and to begin external measure validity question. In line with literature previous works, this work allows to highlight assets and limits of the non-hypothetical measures (BDM mechanism and real choice experiment), first one relative to another, second relative to hedonic measures. Two major results were obtained. First, the B…
Are decisions in a real choice experiment consistent with reservation prices elicited with BDM 'auction'? The case of French baguettes

Abstract The aim of this study was to compare consumer choices observed in a real choice experiment and their reservation prices elicited with the BDM mechanism in order to assess the rationality of participant behaviors. One hundred and seventy-seven participants tested four French baguettes in each task. For the real choice experiment, participants were faced with 17 scenarios (17 × 4 baguette-price combinations). In each method, participants could select a “no purchase” option. Comparing choices and reservation prices made it possible to assess the rationality of participant behaviors. From a strict economic standpoint, 50% of observed choices were fully rational. When one baguette was a…
