We analyze whether the growing importance of passive investors has influenced the campaigns, tactics, and successes of activists. We find activists are more likely to seek board representation when a larger share of the target company’s stock is held by passively managed mutual funds. Furthermore, higher passive ownership is associated with increased use of proxy fights, settlements, and a higher likelihood the activist achieves board representation or the sale of the targeted company. Our findings suggest that the recent growth of passive institutional investors mitigates free-rider problems and facilitates activists’ ability to engage in costly, value-enhancing forms of monitoring.

Leading empiricists and theorists of cities have recently argued that the generation and exchange of ideas must play a more central role in the analysis of cities. This paper develops the first system of cities model with costly idea exchange as the agglomeration force. The model replicates a broad set of established facts about the cross section of cities. It provides the first spatial equilibrium theory of why skill premia are higher in larger cities and how variation in these premia emerges from symmetric fundamentals. (JEL J24, J31, O31, R12, R23)

We provide measures of ethnic and racial segregation in urban consumption. Using Yelp reviews, we estimate how spatial and social frictions influence restaurant visits within New York City. Transit time plays a first-order role in consumption choices, so consumption segregation partly reflects residential segregation. Social frictions also affect restaurant choices: individuals are less likely to visit venues in neighborhoods demographically different from their own. While spatial and social frictions jointly produce significant levels of consumption segregation, we find that restaurant consumption is only about half as segregated as residences. Consumption segregation owes more to social than spatial frictions.
