Working Paper
Intermediation in Networks
I study intermediation in networked markets using a stochastic model of multilateral bargaining in which players compete on different routes through the network. I characterize stationary equilibrium payoffs as the fixed point of a set of intuitive value function equations and study efficiency and the impact of network structure on payoffs. There is never too little trade but there may be an inefficiency through too much trade in states where delay would be efficient. With homogeneous trade surplus the payoffs for players that are not essential to a trade opportunity go to zero as trade ...

A dynamic network model of the unsecured interbank lending market
The unsecured interbank lending market plays a crucial role in financing business activity, a fact underscored by the market's disruption following the Lehman Brothers failure in September 2008. This event, a defining moment in the global financial crisis, fostered greater uncertainty about counterparty risk, an adverse shock that severely curtailed credit supply, hampered monetary policy, and negatively impacted the real economy. To counteract the consequences of the crisis, central banks became the primary intermediaries for a large portion of the money market. However, a single main ...

Empirical network contagion for U.S. financial institutions
We construct an empirical measure of expected network spillovers that arise through default cascades for the U.S. financial system for the period 2002-16. Compared to existing studies, we include a much larger cross section of U.S. financial firms that comprises all bank holding companies, all broker-dealers, and all insurance companies, and consider their entire empirical balance sheet exposures instead of relying on simulations or on exposures arising just through one specific market (like the fed funds market) or one specific financial instrument (like credit default swaps). We find ...

Precautionary Demand and Liquidity in Payment Systems
In large-value real-time gross settlement payment systems, banks rely heavily on incoming funds to finance outgoing payments. Such reliance necessitates a high degree of coordination and synchronization. We construct a model of a payment system calibrated for the U.S. Fedwire system and examine the impact of realistic disruptions motivated by the recent financial crisis. In such settings, individually cautious behavior can have a significant and detrimental impact on the overall functioning of the payment system through a multiplier effect. Our results quantify the mutually reinforcing nature ...
