Abstract

We examine the influence of institutional factors on herding behavior by exploring changes in security analysts’ institutional environments. Specifically, we identify analysts employed at privately held brokers subsequently acquired by a publicly listed institution (hereafter, “treated analysts”). We posit that, after the treatment, analysts are less independent (e.g., due to increased peer pressure or more regulated environments), and thus they issue more herding forecasts. Using a staggered difference-in-differences design, we find that treated analysts issue significantly more herding forecasts in the post-treatment period. In contrast, we do not find a change in herding behavior for analysts subject to acquisitions by non-public brokers, indicating that the institutional change from private to public, not the acquisition per se, drives our inferences. Consistent with the decreasing independency explanation, we find stronger treatment effects for less experienced analysts, more substantial organizational changes, institutional changes associated with higher job uncertainty, and in periods of stricter regulation of public institutions. Taken together, our findings suggest a causal link between the institutional environment and herding behavior.
