Using micro-level data, we examine the impact of socially responsible investment (SRI) funds on corporate behavior. SRI funds select firms with lower pollution, more board diversity, higher employee satisfaction, and better workplace safety. Yet, both in the cross-section and using an exogenous...

Passively managed index funds now hold over 30% of U.S. equity fund assets; this shift raises fundamental questions about monitoring and governance. We show that, relative to active funds, index funds are less effective monitors: (a) they are less likely to vote against firm management on...

We empirically examine the effects of index investing using predictions derived from a Grossman-Stiglitz framework. An increase in index investing leads to lower information production as measured by Google searches, EDGAR views, and analyst reports, yet price informativeness remains unchanged....

After a natural experiment is first used, other researchers often reuse the setting, examining different outcome variables. We use simulations based on real data to illustrate the multiple hypothesis testing problem that arises when researchers reuse natural experiments. We then provide guidance...

After a natural experiment is first used, other researchers often reuse the setting, examining different outcome variables. We examine the consequences of reusing an experimental setting using two extensively studied natural experiments, business combination laws and the Regulation SHO pilot. We...
