Preventing Bank Runs
Banking can be defined as the business of maturity transformation, or "borrowing short to lend long." Economists and policymakers have long viewed banking as inherently unstable, that is, prone to runs. This Economic Brief reviews the intuition and theory behind bank runs and the most popular proposed solutions. It also explores new research suggesting that runs might be prevented by creating a new, low-cost type of deposit contract that eliminates the incentive to run.

CDS Auctions: An Overview
We discuss the historical background of the credit default swap (CDS) market, why CDS auctions were developed, and the most recent literature. We describe the auction rules using the Toys R Us auction as an example. Furthermore, we discuss the theoretical and empirical results presented in Chernov et al. (2013). Empirically, we extend their data to include more recent CDS auctions. Our results support their findings that dealers have incentive to manipulate the auction price downward when the net open interest is positive. Finally, we use novel dealer-level CDS positions to support Chernov et ...

Private Information in Over-the-Counter Markets
We study trading in over-the-counter (OTC) markets where agents have heterogeneous and private valuations for assets. We develop a quantitative model in which assets are issued through a primary market and then traded in a secondary OTC market. Then we use data on the US municipal bond market to calibrate the model. We find that the effects of private information are large, reducing asset supply by 20%, trade volume by 80%, and aggregate welfare by 8%. Using the model, we identify two channels through which the information friction harms the economy. First, the distribution of the existing ...

Essentiality of Money: A Historical Perspective
In this article, I explore the historical development of the concept of essentiality of money, as well as monetary theory more broadly. I begin by introducing the concept of money and its role in facilitating economic activity. I delve into the evolution of monetary theory, starting with the classical theory and the marginal revolution and moving to the division between microeconomics and macroeconomics. Then I discuss the microfoundation revolution in macroeconomics and the debate over the essentiality of money. Finally, I examine the New Keynesian School (which uses reduced-form tools to ...

Sovereign CDS Market: The Role of Dealers in Credit Events
In this paper, we study the credit default swaps (CDS) position of the main dealers in the CDS market close to credit events of sovereign countries. We focus on the credit events of three countries that have faced significant financial distress in the past decade: Argentina, Venezuela, and Ukraine. After introducing the historical background of each country, we find that CDS dealers, defined as the top ten traders of CDS in their respective countries, tend to sell sovereign CDS (hold more negative or less positive positions) when yields/CDS spreads go up. This finding suggests that dealers ...

Sovereign Debt and Credit Default Swaps
ow do credit default swaps (CDS) affect sovereign debt markets? The answer depends crucially on trading frictions, risk-sharing, arbitrage violations, and spillovers from secondary to primary markets. We propose a sovereign default model where investors trade bonds and CDS over the counter via directed search. CDS affect bond prices through several channels. First, CDS act as a synthetic bond. Second, CDS reduce bond-investing risks, allowing exposure to be unwound. Third, CDS availability increases trading profitability, which induces entry and reduces trading costs. Last, these direct ...

Is Money Essential? An Experimental Approach
Journal Article
Inefficiency in a Simple Model of Production and Bilateral Trade
We study a simple model of over-the-counter trade with production. We characterize the equilibrium, and we show that the equilibrium is always inefficient, independent of how the trade surplus is split among trade participants. We argue that this is due to a double hold-up problem that it is at the core of models used to study trade in over-the-counter markets. Finally, we show an example, which we interpret as a limiting case of the general model where the inefficiency vanishes.

Preventing Bank Runs
Diamond and Dybvig (1983) is commonly understood as providing a formal rationale for the existence of bank-run equilibria. It has never been clear, however, whether bank-run equilibria in this framework are a natural byproduct of the economic environment or an artifact of suboptimal contractual arrangements. In the class of direct mechanisms, Peck and Shell (2003) demonstrate that bank-run equilibria can exist under an optimal contractual arrangement. The difficulty of preventing runs within this class of mechanism is that banks cannot identify whether withdrawals are being driven by ...

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 ...
