Abstract
Information asymmetries can prevent markets from operating efficiently. An important example
is the labor market, where employers face uncertainty about the productivity of job candidates.
We examine theoretically and with laboratory experiments three key questions related to hiring
via referrals when employees have private information about their productivity. First, do firms
use employee referrals when there are social ties between a current employee and a future
employee? Second, does the existence of social ties and hiring through employee referrals
indeed alleviate adverse selection relative to when social ties do not exist? Third, does the
existence of social ties have spill-over effects on wages and hiring in competitive labor markets?
The answers to all three questions are affirmative. However, despite the identified positive effect
of employee referrals, hiring decisions fall short of the (second-best) efficient outcome. We
identify risk aversion as a potential reason for this.
