In this paper I explore the relationship between first-birth timing and post-birth labor supply, and how it is influenced by family and career characteristics. Given that pre-birth wages are increasing in fertility delay, the rising opportunity cost of time would suggest that later mothers work more. Yet I only find this pattern for high school graduates. For college graduates, I instead find surprisingly no relationship between first-birth timing and post-birth hours worked, despite strongly increasing pre-birth wages. Furthermore, after controlling for family and career factors, many of which influence hours worked and are correlated with fertility timing, this different pattern by education remains.

This paper examines whether a worker's wage is based in part on information about the performance of her personal contacts. Embedding a sibling model into an employer learning framework, I develop a theory of labor markets with symmetric but imperfect information among employers in which workers are organized into disjoint social groups and workers in the same reference group have correlated abilities. I study wage determination under two alternative belief formation processes: individual learning, under which employers observe only a worker's own schooling and performance, and social learning, under which employers also observe those of her personal contacts.

Using data on the AFQT scores of siblings in the NLSY79, I test for a form of statistical nepotism in which a sibling's performance is priced into a worker's wage. If learning is social, then an older sibling's test score should typically have a larger adjusted impact on a younger sibling's log wage than vice versa. By contrast, if learning is individual, then no such asymmetry should be present. The empirical findings provide strong support for the central prediction of the social learning model. Furthermore, I perform several exercises to identify social learning as the leading explanation for the main results, largely ruling out other potential factors, such as asymmetric skill formation, human capital transfers, and role model effects.
