While there has been work on whether women are more tolerant of outgroups, the ethnic politics literature has generally overlooked the role of gender in explaining interethnic trust. Whatever attention exists often focuses on the gender of the subject—that is, who is doing the trusting—with mixed results. One reason is that the object being entrusted is either not specified or assumed genderless. In this paper, we call attention to the gender of an important entrusted object in interethnic relations: children. We argue people are less willing to have their daughters—compared to their sons—marry an ethnic outgroup. Additionally, this willingness declines as the cultural distance widens. We test this using a survey experiment in Romania where we leverage the diversity in ethnicity and a gendered language structure. Our results highlight the importance of accounting for gender-based differences in studying interethnic trust.
