Abstract

[eng] Our paper focuses on decision-making under risk. We compare group preferences and individual preferences over risk using a lottery-choice experiment inspired by Holt and Laury (2002). In our individual procedure, subjects made lottery choices individually. In our group procedure, groups of three subjects had to reach unanimous lottery-choice decisions through a vote. In a third procedure, called choice procedure, subjects could choose their preferred decision-making method endogenously. Our main findings are that groups are more likely to choose safe lottery than individuals. The results also indicate a positive relationship between preference for risk and willingness to decide alone. The degree of risk aversion is mainly determined by individual characteristics. [fre] L’objet de cet article est d’étudier expérimentalement les processus individuels et collectifs de décision vis-à-vis du risque. Cette étude s’inspire des travaux de Holt et Laury (2002). Les participants prennent leurs décisions seuls, puis au sein de petits groupes, et enfin ils peuvent choisir entre les prendre individuellement ou collectivement. Nos résultats montrent que les groupes ont des attitudes plus prudentes que les individus pris isolément. Par ailleurs, les participants les plus risquophiles sont ceux qui sont disposés à payer les montants les plus élevés pour pouvoir prendre leur décision seuls. Enfin, nos résultats montrent que si le degré d'aversion au risque est influencé par le contexte, il reste en grande partie déterminé par les caractéristiques individuelles.
