Leader-Follower Dynamics in Shareholder Activism
Activist shareholders play a central role in modern corporations, influencing the capital structure, business strategy, and governance of firms. Such “blockholders” range from investors who actively jawbone or break up firms to index funds that are largely passive in that they limit themselves to voting. In between, however, is a key group of blockholders that have historically focused on trading but have embraced activism as an established business strategy in the past few decades. Campaigns involving such “trading” blockholders have become ubiquitous, increasingly targeting ...

The Central Banking Beauty Contest
Expectations can play a significant role in driving economic outcomes, with central banks factoring market sentiment into policy decisions and market participants forming their own assumptions about monetary policy. But how well do central banks understand the expectations of market participants—and vice versa? Our model, developed in a recent paper, features a dynamic game between (i) a monetary authority that cannot commit to an inflation target and (ii) a set of market participants that understand the incentives created by that credibility problem. In this post, we describe the game, a ...

Signaling with Private Monitoring
A sender signals her private information to a receiver who privately monitors the sender’s behavior, while the receiver transmits his private inferences back through an imperfect public signal of his actions. In a linear-quadratic-Gaussian setup in continuous time, we construct linear Markov equilibria, where the state variables are the players’ beliefs up to the sender’s second order belief. This state is an explicit function of the sender’s past play—hence, her private information—which leads to separation through the second-order belief channel. We examine the implications of ...

Leader-Follower Dynamics in Shareholder Activism
We propose a theory of coordination and influence among blockholders. Privately informed activists time their trades in sequence to lower acquisition costs, prompting a strategic use of order flows. Leader activists create trading gains for their followers, ultimately influencing their willingness to bear greater value-enhancing intervention costs. Through this channel, informed trades can exhibit predictability, in sharp contrast with Kyle (1985). We explain how this novel predictability shapes free-rider problems affecting governance, and how it produces price abnormalities analogous to ...
