This paper studies spillovers from older to younger siblings in higher education choices. Exploiting discontinuous admission rules generated by Chile's centralized admission system to higher education, we identify strong sibling spillovers in the choice of college. Having an older sibling enroll in a given college increases by 42% the probability of enrolling in that institution. In contrast, we find no effect on major choices. We show evidence suggesting that sibling spillovers in college choice are mainly driven by siblings deriving benefits from attending college together. [ABSTRACT FROM AUTHOR]
