More on Middlemen: Equilibrium Entry and Efficiency in Intermediated Markets
This paper generalizes Rubinstein and Wolinsky?s model of middlemen (intermediation) by incorporating production and search costs, plus more general matching and bargaining. This allows us to study many new issues, including entry, efficiency and dynamics. In the benchmark model, equilibrium exists uniquely, and involves production and intermediation for some parameters but not others. Sometimes intermediation is essential: the market operates iff middlemen are active. If bargaining powers are set correctly equilibrium is efficient; if not there can be too much or too little economic ...

An Information-Based Theory of Financial Intermediation
We advance a theory of how private information and heterogeneous screening ability across market participants shapes trade in decentralized asset markets. We solve for the equilibrium market structure and show that the investors who intermediate trade the most and interact with the largest set of counterparties must have the highest screening ability. That is, the primary intermediaries are those with superior information?screening experts. We provide empirical support for the model?s predictions using transaction-level micro data and information disclosure requirements. Finally, we study the ...

The Federal Funds Market over the 2007-09 Crisis
This paper measures how the 2007-09 financial crisis affected the U.S. federal funds market. I accomplish this by developing and estimating a structural model of this market, in which intermediation plays a crucial role and borrowing banks differ in their unobserved probability of default. The estimates imply that the expected probability of default increases 0.29 percentage point at the start of the crisis in mid-2007 and then gains a further 1.91 percentage points after the bankruptcy of Lehman Brothers. These increases do not cause a market freeze, however, because simultaneously there is ...
Briefing
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.

The Fed Funds Market during the 2007-09 Financial Crisis
The U.S. federal funds market played a central role in the financial system during the 2007-09 crisis, because it was the market which provided banks with immediate liquidity, even late in the day. Interpreting changes in fed funds rates is notoriously difficult, however, as many of the economic drivers behind the rates are simultaneously changing. In this post, I highlight results from a working paper which untangles the impact of these economic drivers and measures their respective effects on the marketplace using data over a sample period leading up to and during the financial crisis. The ...

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 ...

Hybrid intermediaries
I introduce the concept of hybrid intermediaries: financial conglomerates that control a multiplicity of entity types active in the ?assembly line? process of modern financial intermediation, a system that has become known as shadow banking. The complex bank holding companies of today are the best example of hybrid intermediaries, but I argue that financial firms from the ?nonbank? space can just as easily evolve into conglomerates with similar organizational structure, thus acquiring the capability to engage in financial intermediation. I document instances of the emergence and growth of ...

Frictional Intermediation in Over-the-Counter Markets
We extend Duffie, G?arleanu, and Pedersen?s (2005) search theoretic model of over-the-counter (OTC) asset markets, allowing for a decentralized inter-dealer market with arbitrary heterogeneity in dealers? valuations or inventory costs. We develop a solution technique that makes the model fully tractable and allows us to derive, in closed form, theoretical formulas for key statistics analyzed in empirical studies of the intermediation process in OTC markets. A calibration to the market for municipal securities reveals that the model can generate trading patterns and prices that are ...

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 ...
