Leader-Follower Dynamics in Shareholder Activism
Motivated by the rise of hedge fund activism, we consider a leader blockholder and a follower counterpart who first trade in sequence to build their blocks and then intervene in a firm. With endogenous fundamentals and steering dynamics, the leader ceases to trade in an unpredictable way: she buys or sells to induce the follower to acquire a larger block and thus spend more resources to improve firm value. Key is that the activists have correlated private information—initial blocks, firms' fundamentals, or their own productivity—so that prices either overreact or underreact to order ...

Misinformation in Social Media: The Role of Verification Incentives
We develop a model of a platform featuring producers of fake news as well as users who can share content and verify it at a cost. Since users supply news to other users, their actions affect fake news prevalence and strategic complementarities can arise: high levels of verification can lead to low prevalence of fake content, in turn inducing more unverified sharing that sustains high levels of verification. Equilibria in this market then arise as intersection points between a standard supply curve and a novel correspondence that generalizes a demand function to account for the users’ ...

Breaking Down the Market for Misinformation
The spread of misinformation online has been recognized as a growing social problem. In responding to the issue, social media platforms have (i) promoted the services of third-party fact-checkers; (ii) removed producers of misinformation and downgraded false content; and (iii) provided contextual information for flagged content, empowering users to determine the veracity of information for themselves. In a recent staff report, we develop a flexible model of misinformation to assess the efficacy of these types of interventions. Our analysis focuses on how well these measures incentivize users ...

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 ...

Coexistence of Banks and Non-Banks: Intermediation Functions and Strategies
What is the essence of non-bank financial intermediation? How does it emerge and interact with intermediation performed by banks? To investigate these questions, we develop a model-based survey: we classify existing models into different intermediation functions á la Merton (1995) to show that variations of them admit a common modeling structure; then, we extend or reinterpret the resulting models to connect equilibrium strategies to non-bank activities in practice. Particular emphasis is placed on the coexistence of banks and non-banks: how their competition, or the extent of cooperation ...

Who Is Borrowing and Lending in the Eurodollar and Selected Deposit Markets?
A recent Liberty Street Economics post discussed who is borrowing and lending in the federal funds (fed funds) market. This post explores activity in two other markets for short-term bank liabilities that are often perceived as close substitutes for fed funds—the markets for Eurodollars and “selected deposits.”

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 ...

Who’s Borrowing and Lending in the Fed Funds Market Today?
The Federal Open Market Committee (FOMC) communicates the stance of monetary policy through a target range for the federal funds rate, which is the rate set in the market for uncollateralized short-term lending and borrowing of central bank reserves in the U.S. Since the global financial crisis, the market for federal funds has changed markedly. In this post, we take a closer look at who is currently trading in the federal funds market, as well as the reasons for their participation.

Nonbanks and Banks: Alone or Together?
Nonbank financial institutions (NBFIs) constitute a variety of entities—fintech companies, mutual funds, hedge funds, insurance companies, private debt providers, special purpose vehicles, among others—that have become important providers of financial intermediation services worldwide. But what is the essence of nonbank financial intermediation? Does it have any inherent advantages, and how does it interact with that performed by banks? In this Liberty Street Economics post, which is based on our recent staff report, we provide a model-based survey of recent literature on nonbank ...
