Abstract: This purpose of this study was to test the effect of sibling status on giving behavior. In an effort to bridge the gap between the psychological research on personality differences, and the economic literature on giving behavior, two classic behavioral economics experiments were used to gauge the significance of sibling status with regards to benevolent and selfish motivations for giving in only children and sibling children. Results showed that in general, sibling children displayed greater benevolence, while only children showed stronger evidence of selfishness. The results of this study hold potential implications for the comprehension of other regarding behavior in children and merit further exploration of family structure’s relevance to giving behavior.
