VoxEU, March 20, 2019, with Markus Brunnermeier. HTML. Both proponents and opponents have suggested that CBDC would fundamentally change the macroeconomy, either for the better or the worse. We question this paradigm. We derive an equivalence result according to which the introduction of CBDC need not alter the allocation nor the price system. And we argue that key concerns put forward in discussions about CBDC are misplaced. See also our VoxEU book chapter and my paper from last year.

Accepted for publication in the International Journal of Central Banking. PDF. This paper offers a macroeconomic perspective on the “Reserves for All” (RFA) proposal to let the general public hold electronic central bank money and transact with it. I propose an equivalence result according to which a marginal substitution of outside money (e.g., RFA) for inside money (e.g., deposits) does not affect macroeconomic outcomes. I identify key conditions for equivalence and argue that these...

With Markus Brunnermeier. March 2019. PDF. In Antonio Fatás, editor, The Economics of Fintech and Digital Currencies, VoxEU book, London. We address five key concerns that are frequently put forward: 1. Aren’t digital currencies just a hype, now that crypto ‘currencies’ like Bitcoin have proved too volatile and expensive to serve as reliable stores of value or mediums of exchange? This confuses things. A central bank digital currency (CBDC) is like cash, only digital; Alipay, Apple Pay,...

Mimeo, January 2019, with Markus Brunnermeier. PDF. We propose a generic model of money and liquidity. We provide sufficient conditions under which a swap of private (inside) against public (outside) money leaves the equilibrium allocation and price system unchanged. We apply the results to Central Bank Digital Currency, the “Chicago Plan,” and the Indian de-monetization experiment.
