Collective vs. Individual Risk Attitudes

Short Description: Household decision making with regard to consumption and investment relies on its members’ risk attitudes. The SOEP-IS data collected in this experiment shines a light on how the individual risk preferences are aggregated in a household and how joint decisions about risky investments are made.

Experimental Details: Each participant makes an individual investment decision. The household is given 10 € and they either collectively decide how much to invest (= treatment 1), or a randomly chosen decision maker decides for the household (= treatment 2).

Incentives: Willingness to pay for 11 lotteries (probability= 0.5) from 10 EUR endowment. Xlow=10-qi Xhigh=10+2qi Min. Payoff: 0 €/ Max. Payoff: 30 €
