This paper tests whether home bias exists among information producers. We find that credit analysts are more generous when rating issuers from their home states compared to (a) benchmark analysts from outside the state and (b) their own standards for rating issuers from other states. This home analyst effect strengthens around key rating certifications (AAA and investment grade), reduces credit spreads, and expands affected issuers’ debt capacity. We conduct several tests to address the possibility that the observed home analyst effect reflects a selection effect based on informational advantages and conclude that it instead reflects a home bias.
