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 ...

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 ...

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) ...

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 ...

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 ...

GameStop, AMC and the Self-Fulfilling Beliefs of Stock Buyers
The recent stock market gyrations of GameStop and AMC Entertainment illustrate that companies' fates can sometimes hinge on self-fulfilling beliefs. Pessimistic expectations can raise the specter of bankruptcy, while optimistic expectations can allow for survival and eventual success. We show how it is sometimes possible for small coalitions of buyers — such as those that formed on the online forum Reddit — to tip the balance in favor of an optimistic scenario. By doing so, a coalition can reap large profits and fundamentally improve a company's prospects.

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 ...

How Post-2008 Financial Regulations Impacted Corporate Bond Liquidity
We review empirical findings regarding the impact of post-2008 financial regulations on the liquidity of corporate bond markets in the U.S. We first show that traditional measures of market liquidity improved in recent years. At the same time, the cost of illiquidity also increased. We then discuss findings showing that — after the regulations were implemented — dealer capital commitment, trade frequency and size decreased, while dealer bid-ask spread increased. The increase in dealer bid-ask spread is compensated by a change in the composition of the liquidity provision. Liquidity is ...

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 ...
