The IRS recently dealt a blow to Bitcoin enthusiasts by ruling that Bitcoin and other similar currencies should be treated as property – and not foreign currency – for income tax purposes. As a result, those who use bitcoins to purchase goods or services must report gain or loss on each...

Current financial discourse suggests the imminence of a cashless society, a concept that arose from the global popularization of digital financial services and the development of technologies with the potential for application in financial markets. However, claims about the impending...

For an intermediated central bank digital currency (CBDC) to be successful, central banks will need to develop sustainable economic models where intermediaries and end users derive value and central banks achieve their policy goals. This note presents a framework for analyzing different economic...

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...

Bitcoin, a cryptocurrency invented in 2008 is both puzzling and inspiring. High volatility of its price is challenges financial analysts as well as scholars. We look at the incentive mechanisms that make Bitcoin work, and we discuss current and potential uses of Bitcoin and technologies inspired...

Does Bitcoin's proof-of-work (PoW) protocol serve its intended purpose of enabling and supporting a decentralized payment system? To address this question, we develop a game theoretical model where firms invest in research and development (R&D) before competing in a Bitcoin mining game. We show...

Can Bitcoin remain tamper proof in the long run? We use block-level data from the Bitcoin blockchain to estimate the impact of congestion and the USD price on fee rates. The introduction and adoption of the Segwit protocol allows us to identify an aggregate demand curve for bitcoin transactions....

We use block level data from the Bitcoin blockchain to estimate the impact of congestion and the USD price on average fee rates. The introduction and adoption of the Segwit protocol allows us to identify an aggregate demand curve for bitcoin transactions. We find that Segwit has reduced fee...

We study the optimal design of a central bank digital currency (CBDC) in an environment where agents sort into cash, CBDC, and bank deposits according to their preferences over anonymity and security; and where network effects make the convenience of a payment instrument depend on the number of...

Blockchain technology breathes new life into the classical analysis of money as a substitute for a ledger of all past transactions. While it involves updating the ledger through a decentralized consensus on the unique truth, the robustness of the equilibrium that supports this consensus depends...
