The formation of economic preferences in childhood and adolescence has long-term consequences for social and economic outcomes later in life. Hence, it is important to understand what shapes economic preferences. Running experiments with 525 teenagers, we examine the effects of both birth order and siblings’ sex composition on economic preferences. We find that both aspects matter. Second born children are typically less patient, less risk averse, and more trusting. However, siblings’ sex composition interacts with these findings, such that the common finding that second born children are more risk taking is only confirmed in case of same-sex siblings, while with mixed-sex siblings gender dominates birth order. For trust, gender differences are larger with mixed-sex siblings than in the single-sex case. Only for patience siblings’ sex composition does not matter.
