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...

The standard economic approach to considering the effects of a policy tends to neglect the prospect of regulatory ambiguity. I describe four sources of regulatory ambiguity and survey the literature considering the effects of ambiguity on entrepreneurial activity. I also explain how...

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...

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, randomness still exists in consumption preferences. We offer an endogenous matching model of...

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...

In this paper, I show the validity of and the relationship between two previously unrelated claims in monetary theory. The first claim, made by Earl Thompson, is that privately-issued bank notes pay a positive rate of return in a competitive equilibrium. The second claim, made by Fischer Black,...

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...

Some have argued that nominal income targeting is desirable because it would replicate characteristics of a free banking regime. However, the degree to which this is true and desirable depends on the properties of commodity-based monetary regimes. In this paper, I provide a model of commodity...

We employ a monetary model with endogenous search and random consumption preferences to consider the extent to which governments can ban bitcoin. We define a ban as a policy whereby government agents refuse to accept bitcoin and mete out punishments to private agents caught using it. After...

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 currency? There are two views in the literature. The first requires offering an item with use value to some...
