This paper is aimed at studying the dynamics of consumers' preferences for corporate social responsibility. The data come from both a Discrete Choice Experiment (DCE) and a field experiment conducted in a realmarket setting. The results show that in a static setting (first month) predictions of a standard DCE study and real market shares are statistically similar for the various profiles of corporate social responsibility. However, as time evolves real market shares present some dynamic patterns that are not mirrored by the standard DCE predictions. The overall conclusion is that differences between realmarket behavior and DCE data can be attributed to the lack of learning experience or adaptation in DCE surveys rather than to the hypothetical nature of the experiments.
