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...

We study information production and diffusion resulting from dynamic interactions between different types of informed investors in financial markets. Using a theoretical framework that exploits the setting of the Q&A section of earnings conference calls, we predict that information production...

Based on documented population gender differences in risk aversion, some argue the crisis would not have happened if Lehman Brothers had been Lehman Sisters. Such generalizations from the population ignore the role of selection. We illustrate the importance of selection by comparing finance to...

Would the crisis have happened if Lehman Brothers had been Lehman Sisters? Evidence on population gender differences in risk-aversion suggest not. Consistent with the idea that female managers need not be more risk-averse than men, we find that listed banks with more female directors did not...

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....

This paper investigates the reasons that lead to modification of auditors' opinions. We revisit the conclusions of prior US-based research on whether a modification highlights likely earnings management activities. Extending this research, we consider an alternate explanation that managers...
