Abstract: 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 alsoindicate a positive relationship between preference for risk and willingness to decide alone. The degree of risk aversion is mainly determined by individual characteristics.
