Résumé / abstract  : We study the effects of collective deliberation on individual preferences regarding distributing resources in a group. In a lab experiment, we elicit subject’s preferences over payoff allocations before and after group deliberation. More precisely, subjects are grouped by five and they have to report their preference over payoff allocations among them. The choice between allocations implies a trade-off between equality and efficiency. Here the deliberation consists of a free discussion between the members of the group for a period of 10 minutes. We find that group deliberation has a significant effect on individual preferences. On the one hand, subjects tend to value more equality than efficiency after deliberation. On the other hand, their preference after deliberation seems to fall into line with the ones of the poorest members (rather than of the median member). Robustness treatments suggest that these changes in preference are not explained solely by an identity effect or a taste for conformity.
