Seigniorage Payments and the Federal Reserve’s New Operating Regime
w/ Bryan Cutsinger
Economics Letters, 2022. [EL] [SSRN] [Data]

We consider the Federal Reserve’s remittances to the Treasury and extend the estimates offered by Barro (1982) and Jefferson (1998) to assess the net effect of the Fed’s new operating regime on seigniorage payments. Most measures indicate that the Fed’s new operating regime has increased the level of seigniorage and its relative importance in total tax receipts. Whether seigniorage from domestic and foreign holdings of U.S. currency has become more or less important as a source of revenue depends on the measure of seigniorage used.

Cash, Crime and Cryptocurrencies
w/ Joshua R. Hendrickson
Quarterly Review of Economics and Finance, 2022. [QREF] [SSRN]

In The Curse of Cash, Kenneth Rogoff lists reductions in criminal activity and tax evasion among the primary benefits of eliminating cash. We maintain that, to the extent that individuals are interested in purchasing illicit goods and services or evading taxes, eliminating cash will encourage them to switch to close substitutes. Hence, governments intent on realizing the benefits cited by Rogoff would not merely need to eliminate cash. They would also need to ban alternatives. This is especially relevant given the proliferation of cryptocurrencies, which provide a fair degree of anonymity for users.

Central Bank Independence and the Federal Reserve’s New Operating Regime
w/ Jerry L. Jordan
Quarterly Review of Economics and Finance, 2022. [QREF] [SSRN]

The Federal Reserve is exposed to a greater degree of political influence under its new operating regime. We survey the relevant literature and describe the Fed’s new operating regime. Then we explain how the regime change reduced de facto central bank independence. In brief, the regime change increased the appointment power of the President and improved the bargaining power of Congress. We offer some suggestions for bolstering de facto independence at the Fed.

The Federal Reserve’s Response to the COVID-19 Contraction: An Initial Appraisal
w/ Nicolas Cachanosky, Bryan Cutsinger, Thomas L. Hogan, and Alexander W. Salter
Southern Economic Journal, 2021. [SEJ] [SSRN]

We provide an initial assessment of the Federal Reserve’s policy response to the COVID-19 contraction. We briefly review the historical episode and consider the standard textbook treatment of a pandemic on the macroeconomy. We summarize and then evaluate the Fed’s monetary and emergency lending policies through the end of 2020. We credit the Fed with promoting monetary stability while maintaining that it could have done more. We argue that the Fed could have achieved stability without employing its emergency lending facilities. Although some facilities likely helped to promote general liquidity, others were primarily intended to allocate credit, which blurs the line between monetary and fiscal policy. These credit allocation facilities were unwarranted and unwise.

Is Bitcoin Money? And What That Means
w/ Peter K. Hazlett
Quarterly Review of Economics and Finance, 2020. [QREF] [SSRN]

In a recent article, Yermack (2015) argues that bitcoin is not money because it functions poorly as a medium of exchange, unit of account, and store of value. We offer a more conventional view. We maintain that the standard approach classifies an item as money if and only if it functions as a commonly-accepted medium of exchange. Then, we show that the demand for bitcoin is comparable to the demand for many government-issued monies. Finally, we argue that bitcoin is money—though perhaps only over a relatively small domain at present.

Is Bitcoin a Decentralized Payment Mechanism?
w/ Sean Stein Smith
Journal of Institutional Economics, 2020. [JoIE] [SSRN]

We make a distinction between centralized, decentralized, and distributed payment mechanisms. A centralized payment mechanism processes a transaction using a trusted third party. A decentralized payment mechanism processes a transaction between the parties to the transaction. A distributed payment mechanism relies on the network of users to process a transaction on a shared ledger. We maintain that bitcoin is neither a centralized nor a decentralized payment mechanism. It is, instead, a distributed payment mechanism. We then consider decentralized and centralized aspects of the broader bitcoin payment space.

Endogenous Matching and Money with Random Consumption Preferences
w/ Thomas L. Hogan
B.E. Journal of Theoretical Economics, 2019. [BEJTE] [SSRN]

Current money matching models employ either random matching or endogenous matching processes, both of which oversimplify the problem. We maintain that, although most economic interactions are intentional, some randomness remains. We offer an endogenous matching model of money with random consumption preferences. Our model preserves the intentionality of economic interactions while leaving scope for chance. We identify the conditions for potential monetary and nonmonetary equilibria and compare them to those of other endogenous matching and random matching models.

Adaptation and Central Banking
w/ Alexander W. Salter
Public Choice, 2019. [PC] [SSRN]

What or who governs central bank decisions? Most considerations focus on motivations. Instead, we consider the extent to which specific behaviors have adaptive value in the context of central banking. From that perspective, poor decisions are not the product of poor motivations. They are, instead, a product of the poor institutions within which central bank decision makers operate.

Getting Off the Ground: The Case of Bitcoin
Journal of Institutional Economics, 2019. [JoIE] [SSRN]

By declaring an item legal tender or making it publicly receivable, governments might generate sufficient demand to determine the medium of exchange. How do private actors launch a new money? There are two views in the literature. The first requires offering an item with a use value to some agents that is distinct from its role as a medium of exchange. The second suggests that agents might coordinate on an intrinsically useless item. With these views in mind, I survey the logs from the original bitcoin forum, bitcoin-list. I find that early participants in the bitcoin community understood the importance of coordination and took steps to coordinate users.

Banning Bitcoin
w/ Joshua R. Hendrickson
Journal of Economic Behavior & Organization, 2017. [JEBO] [SSRN]

We employ a monetary model with endogenous search and random consumption preferences to consider the extent to which a government can ban an alternative currency, like bitcoin. We define a ban as a policy whereby government agents refuse to accept an alternative currency and mete out punishments to private agents caught using it. After identifying monetary equilibria where an alternative currency is accepted, we then derive the conditions under which a ban might deter its use. As in earlier studies, we show that a government of sufficient size can prevent an alternative currency from circulating without relying on punishments. We also show that, given its size, a government can ban an alternative currency so long as it is willing and able to mete out sufficiently severe punishments.

Bitcoin and the Bailout
w/ Alexander W. Salter
Quarterly Review of Economics and Finance, 2017. [QREF] [SSRN]

On March 16, 2013, Cyprus announced that it would accept a bailout that required imposing a one-time levy on bank deposits. It has been argued that, by making traditional deposit accounts seem less secure, the bailout announcement prompted some to consider — or reconsider — using the cryptocurrency bitcoin. Relying on rank data for a subset of apps, existing studies maintain that interest in bitcoin increased following the announcement, especially in countries with troubled banks. We argue that (1) focusing on a subset of apps does not allow one to distinguish a general increase in the demand for bitcoin apps from a substitution between bitcoin apps and (2) changes in rank data are a poor predictor of changes in the number of downloads. In order to address these concerns, we collect rank data for all fifteen bitcoin apps available at the time and use an established technique to estimate an index of downloads for each country considered. We find that, while downloads of bitcoin apps increased following the announcement, the observed effect was not especially pronounced in countries thought to have had troubled banking systems at the time.

The Political Economy of Bitcoin
w/ Joshua R. Hendrickson and Thomas L. Hogan
Economic Inquiry, 2016. [EI] [SSRN]

The recent proliferation of bitcoin has been a boon for users but might pose problems for governments. Indeed, some governments have already taken steps to ban or discourage the use of bitcoin. In a model with endogenous matching and random consumption preferences, we find multiple monetary equilibria including one in which bitcoin coexists with official currency. We then identify the conditions under which government transactions policy might deter the use of bitcoin. We show that such a policy becomes more difficult if some users strictly prefer bitcoin because they can avoid other users holding the official currency in the matching process.

Cryptocurrencies, Network Effects, and Switching Costs
Contemporary Economic Policy, 2016. [CEP] [SSRN]

Cryptocurrencies are digital alternatives to traditional government-issued paper monies. Given the current state of technology and skepticism regarding the future purchasing power of existing monies, why have cryptocurrencies failed to gain widespread acceptance? I offer an explanation based on network effects and switching costs. In order to articulate the problem that agents considering cryptocurrencies face, I employ a simple model developed by Dowd and Greenaway (1993). The model demonstrates that agents may fail to adopt an alternative currency when network effects and switching costs are present, even if all agents agree that the prevailing currency is inferior. The limited success of bitcoin—almost certainly the most popular cryptocurrency to date—serves to illustrate. After briefly surveying episodes of successful monetary transition, I conclude that cryptocurrencies like bitcoin are unlikely to generate widespread acceptance in the absence of either significant monetary instability or government support.

Positively Valued Fiat Money after the Sovereign Disappears: The Case of Somalia
w/ Lawrence H. White
Review of Behavioral Economics, 2016. [RBE] [SSRN]

The case of the Somali shilling defies the historical view that sovereign powers (i.e., legal tender status, public receivability) are necessary to explain the acceptance of fiat money at a positive value. Following the Somali state’s collapse in 1991, irredeemable paper shillings have continued to circulate at a positive value. Acceptance under statelessness is explained by a history that made continued acceptance a focal point among self-fulfilling strategies. Our explanation is consistent with an extended Kiyotaki-Wright model of fiat money. Although sovereign power may be necessary to launch a fiat money in practice, we maintain that it is not necessary for its survival.

The Monetary Mechanism of Stateless Somalia
Public Choice, 2015. [PC] [SSRN]

A peculiar monetary institution emerged during the period of interregnum in Somalia from January 1991 to August 2012. Without a functioning government to restrict the supply of notes in circulation, Somalis found it profitable to contract with foreign printers and import forgeries. The exchange value of the largest denomination Somali shillings note fell from US $0.30 in 1991 to US $0.03 in 2008. However, the purchasing power eventually stabilized at the cost of producing additional notes.
