Abstract
We present representative evidence that perceptions about relative rank in the wealth distribution shape individuals’ willingness to take risks, and that this effect is moderated by a key personality trait, an individuals’ locus of control. Using a large-scale survey in Germany, we manipulate perceptions of relative wealth standing by randomly varying response categories when asking respondents about their wealth level. We measure their risk tolerance in a subsequent incentivized lottery task. Our results indicate that respondents who are induced to perceive
their relative position as low choose riskier lotteries on average. We show that this effect is mainly driven by people who more firmly believe that life outcomes are beyond their control (external locus of control). This interaction between preferences and individuals’ underlying belief systems highlights the benefits of incorporating personality traits into economic analysis.

Experimental Details
Interventions
Intervention(s)
We implemented an incentivized survey experiment in the Socio-Economic Panel Innovation Sample (SOEP-IS). The SOEP-IS is a representative longitudinal survey of German households. We manipulate respondents' perceptions about their relative wealth and subsequently measure their risk tolerance through an incentivized lottery task, which allows us to parameterize a respondent's utility function.

Experimental Design
Experimental Design
We manipulate respondents' perception about their relative wealth. Specifically, we ask respondents about their net wealth and randomly vary the response categories of the question.3 Half of the respondents see response categories with wide intervals, e.g., the lowest category ranges up to 275,000 euro (treatment condition). Accordingly, the overwhelming majority of respondents (about 80 percent) should place themselves into this lowest category, and thus perceive their relative wealth rank as low. The other half of respondents receive response categories with small intervals where, for example, the lowest category was less than 2,500 euro (control condition). This implies, in contrast to the treatment condition, that the majority of respondents should locate themselves in the middle and top categories and thus perceive their wealth rank as higher. Subsequently, we measure respondents' risk tolerance through an incentivized lottery task.
