Making Friends Meet: Network Formation with Introductions
This paper proposes a parsimonious model of network formation with introductions in the presence of intermediation rents. Introductions allow two nodes to form a new connection on favorable terms with the help of a common neighbor. The decision to form links via introductions is subject to a trade-off between the gains from having a direct connection at lower cost and the potential losses for the introducer from lower intermediation rents. When nodes take advantage of introductions, stable networks tend to exhibit a minimum amount of clustering. At the same time, intermediary nodes have ...

The Effect of Primary Dealer Constraints on Intermediation in the Treasury Market
Using confidential microdata, we show that shocks to primary dealers’ risk-bearing constraints have significant effects on the US Treasury securities market. In response to tighter constraints, dealers reduce their Treasury positions, triggering a reduction in aggregate turnover and an increase in bid–ask spreads. These effects are more pronounced in securities that contribute more to the utilization of risk constraints. The impaired intermediation also affects Treasury yields, amplifying the yield response to net demand shifts. Moreover, tighter dealer constraints weaken Treasury auction ...

A Dynamic Model of Intermediated Consumer Credit and Liquidity
We construct a model of consumer credit with payment frictions, such as spatial separation and unsynchronized trading patterns, to study optimal monetary policy across different interbank market structures. In our framework, intermediaries play an essential role in the functioning of the payment system, and monetary policy influences the equilibrium allocation through the interest rate on reserves. If interbank credit markets are incomplete, then monetary policy plays a crucial role in the smooth operation of the payment system. Specifically, an equilibrium in which privately issued debt ...

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 ...

Making Friends Meet: Network Formation with Introductions
High levels of clustering—the tendency for two nodes in a network to share a neighbor—are ubiquitous in economic and social networks across different applications. In addition, many real-world networks show high payoffs for nodes that connect otherwise separate network regions, representing rewards for filling “structural holes” in the sense of Burt (1992) and keeping distances in networks short. This paper proposes a parsimonious model of network formation with introductions and intermediation rents that can explain both these features. Introductions make it cheaper to create ...

U.S. Treasury Market Functioning from the GFC to the Pandemic
This article examines U.S. Treasury securities market functioning from the global financial crisis (GFC) through the Covid-19 pandemic given the ensuing market developments and associated policy responses. We describe the factors that have affected intermediaries, including regulatory changes, shifts in ownership patterns, and increased electronic trading. We also discuss their implications for market functioning in both normal times and times of stress. We find that alternative liquidity providers have stepped in as constraints on dealer liquidity provision have tightened, supporting ...

Intermediation and Bank Liquidity: A Conference Recap
How might a central bank digital currency alter banking system operations? What is the effect of credit easing on the dynamics of bank runs? Does increased competition among banks mean a more fragile banking system, and what can be done about it? These were among the research questions addressed by economists during a recent Richmond Fed research conference.

Corporate Bond Liquidity During the COVID-19 Crisis
We study liquidity conditions in the corporate bond market during the COVID-19 pandemic, and the effects of the unprecedented interventions by the Federal Reserve. We find that, at the height of the crisis, liquidity conditions deteriorated substantially, as dealers appeared unwilling to absorb corporate debt onto their balance sheets. In particular, we document that the cost of risky-principal trades increased by a factor of five, forcing traders to shift to slower, agency trades. The announcements of the Federal Reserve’s interventions coincided with substantial improvements in trading ...

Inventory, Market Making, and Liquidity in OTC Markets
We develop a search-theoretic model of a dealer-intermediated over-the-counter market. Our key departure from the literature is to assume that, when a customer meets a dealer, the dealer can sell only assets that it already owns. Hence, in equilibrium, dealers choose to hold inventory. We derive the equilibrium relationship between dealers’ costs of holding assets on their balance sheets, their optimal inventory holdings, and various measures of liquidity, including bid-ask spreads, trade size, volume, and turnover. Using transaction-level data from the corporate bond market, we calibrate ...
