Using unique data on investor views of EDGAR company filings, we document that many investors engage in governance research. However, investors’ monitoring is disproportionately focused on large firms and firms with meetings outside the busy spring proxy season. Using an instrumental variables approach that isolates the drop in governance attention during the busy proxy season, we show that governance research is related to investors’ monitoring of firms, through voice and exit. Moreover, governance research disciplines management, who, as a result, reduce investments and increase payouts. The concentration of attention results in joint monitoring of a relatively small subset of firms.
