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 ...

Sovereign CDS Dealers as Market Stabilizers
Economists at the Richmond Fed analyze the role of dealer-provided liquidity in sovereign credit default swap markets. Using newly available data from the Depository Trust and Clearing Corporation, they track the positions held by large dealers during crises in Ukraine, Venezuela, and Argentina. The researchers find that large dealers tended to increase their provision of insurance as risk increased during those episodes — a finding that is consistent with the notion that they tend to act as market stabilizers during times of turmoil.

Nonparametric Estimation of the Diamond-Dybvig Banking Model
I propose a nonparametric structural estimator for the distribution of liquidity needs in a version of the Diamond and Dybvig (1983) model when only the aggregate level of withdrawals is observed. The model is an extension of Peck and Shell (2003) with a continuum of depositors. I show how the characterization of the optimal contract proposed in Sultanum (2014) can be used to estimate the distribution of aggregate liquidity needs. The method builds on the literature of estimation of auctions. More precisely, it uses the indirect approach proposed by Guerre et al. (2000). Guerre et al. (2000) ...

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.

The Cost of Information in the Blockchain: A Discussion of Routledge and Zetlin-Jones
The volatility of crypto currencies hinders their ability to be media of exchange or stores of value, leading to the implementation of exchange-rate pegs in an attempt to stabilize these currencies. This strategy has been used by crypto currencies such as US Dollar Tether, Steem Backed Dollar and TrueUSD; and was previously adopted in countries such as Brazil, Mexico and Argentina. However, an exchangerate peg is vulnerable to speculative attacks if it is not 100% backed by reserves, as discussed in Obstfeld (1996). Using insights from the bank-run literature, Routledge and Zetlin-Jones ...

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 ...

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 ...

Financial Fragility and Over-the-Counter Markets
This paper studies the interaction between financial fragility and over-the-counter markets. In the model, the financial sector is composed of a large number of investors divided into different groups, which are interpreted as financial institutions, and a large number of dealers. Financial institutions and dealers trade assets in an over-the-counter market la Duffie et al. (2005) and Lagos and Rocheteau (2009). Investors are subject to privately observed preference shocks, and financial institutions use the balanced team mechanism, proposed by Athey and Segal (2013), to implement an ...

A Crises-Bailouts Game
This paper studies the optimal design of a liability-sharing arrangement as an infinitely repeated game. We construct a noncooperative model with two agents: one active and one passive. The active agent can take a costly and unobservable action to reduce the incidence of crisis, but a crisis is costly for both agents. When a crisis occurs, each agent decides unilaterally how much to contribute mitigating it. For the one-shot game, when the avoidance cost is too high relative to the expected loss of crisis for the active agent, the first-best is not achievable. That is, the active agent ...
