Technological Change and Central Banking
The decentralized autonomous organization (DAO) represents a radically new way to manage databases. Since money and payments are all about managing databases and since banks play a central role in money and payments, DAO-based money and payments systems are potentially a disruptive force in the banking system—which includes central banks. One would normally expect regulatory frameworks to evolve with a changing technological landscape. However, the decentralized governance structure characteristic of DAOs renders it near impossible to regulate these entities directly—a property that makes ...

Bitcoin Is Not a New Type of Money
Bitcoin, and more generally, cryptocurrencies, are often described as a new type of money. In this post, we argue that this is a misconception. Bitcoin may be money, but it is not a new type of money. To see what is truly new about Bitcoin, it is useful to make a distinction between “money,” the asset that is being exchanged, and the “exchange mechanism,” that is, the method or process through which the asset is transferred. Doing so reveals that monies with properties similar to Bitcoin have existed for centuries. However, the ability to make electronic exchanges without a trusted ...

Payment networks in a search model of money
In a simple search model of money, we study a special kind of memory that gives rise to an arrangement resembling a payment network. Specifically, we assume that agents can pay a cost to access a central database that tracks payments made and received. Incentives must be provided to agents to access the central database and to produce when they participate in this arrangement. We also study policies that can loosen these incentive constraints. In particular, we show that a "no-surcharge" rule has good incentive properties. Finally, we compare our model with that of Cavalcanti and Wallace.

Beyond the Doomsday Economics of “Proof-of-Work” in Cryptocurrencies
This paper discusses the economics of how Bitcoin achieves data immutability, and thus payment finality, via costly computations, i.e., ?proof-of-work.? Further, it explores what the future might hold for cryptocurrencies modelled on this type of consensus algorithm. The conclusions are, first, that Bitcoin counterfeiting via ?double-spending? attacks is inherently profitable, making payment finality based on proof-of-work extremely expensive. Second, the transaction market cannot generate an adequate level of ?mining? income via fees as users free-ride on the fees of other transactions in a ...

Self-Insurance and the Risk-Sharing Role of Money
Overcoming the lack of coincidence of wants is a well-acknowledged role of money. In this review, I illustrate that the use of money also promotes risk-sharing in the society: when individuals hold money, it helps other individuals mitigate their own liquidity risks.

U. S. consumer cash use, 2012 and 2015: an introduction to the Diary of Consumer Payment Choice
U.S. consumer cash payments averaged 26 percent of all U.S. consumer payments by number (volume share) from 2008 to 2015, according to the Survey of Consumer Payment Choice (SCPC), and were essentially unchanged between 2012 and 2015. New estimates from the Diary of Consumer Payment Choice (DCPC) show that the volume share of consumer cash payments is higher than estimated in the SCPC and suggest that the cash volume share was 8 percentage points lower in 2015 than in 2012. The DCPC most likely does not provide an accurate estimate of the actual change in the cash volume share, however, due ...

Bitcoin as money?
The spectacular rise late last year in the price of Bitcoin, the dominant virtual currency, has attracted much public attention as well as scholarly interest. This policy brief discusses how some features of Bitcoin, as designed and executed to date, have hampered its ability to perform the functions required of a fiat money??as a medium of exchange, unit of account, and store of value. Furthermore, we document how various forms of intermediaries have emerged and evolved within the Bitcoin network, particularly noting the convergence toward concentrated processing, both on and off the ...

Money, Banking, and Old-School Historical Economics
We review developments in the history of money, banking, and financial intermediation over the last twenty years. We focus on studies of financial development, including the role of regulation and the history of central banking. We also review the literature of banking and financial crises. This area has been largely unaffected by the so-called new econometric methods that seek to prove causality in reduced form settings. We discuss why historical macroeconomics is less amenable to such methods, discuss the underlying concepts of causality, and emphasize that models remain the backbone of our ...

The Future of Money and Its Implications for Society, Central Banks, and the International Monetary System
This new wave of financial innovations has broad implications for society, banking, and central banking: Digital platforms can ease entry for financial services providers, increase transactional efficiency, and widen access to and participation in the financial system. They could also decrease the use of cash and alter the U.S. dollar's role as today's vehicle currency.

Liquidity, Capital Pledgeability and Inflation Redistribution
We study the redistributive effects of expected inflation in a microfounded monetary model with heterogeneous discount factors and collateral constraints. In equilibrium, this heterogeneity leads to borrowing and lending. Model assumptions also guarantee a tractable distribution of money and capital holdings. Several results emerge from our analysis. First, in this framework expected inflation is detrimental to capital accumulation. Second, expected inflation affects borrowing and lending when collateral constraints are present, thus also inducing redistributive effects through credit. Third, ...
