Theoretical models of groups suggest that sub-group usage can affect communication among members and group decision-making. To examine the trade-offs from forming sub-groups, we assemble a detailed dataset on corporate boards (groups) and committees (sub-groups). Boards have increasingly used committees formally staffed entirely by outside directors. Our data show that twenty-five percent of all director meetings occurred in such committees in 1996; this increased to 45% by 2010. Our evidence suggests that granting formal authority to such committees can impair communication and decision-making. Sub-groups are relatively understudied, but our results suggest that they play an important role in group functioning and corporate governance.

The literature examining analyst activity assumes that access to management is valued by analysts and their employers. We propose a readily observable measure of access: How often an analyst is invited to be among the first to ask questions in the Q&A session of an earnings conference call. These “early participants” are more successful in the labor market than peers from the same brokerage when their brokerages close. Our results show that access is valued by both sell-side and buy-side employers and reflects connectivity to management as well as analyst skill dimensions not captured in traditional measures of performance.
