Different aspects of the Libra proposal that various authors have emphasized: Jameson Lopp on OneZero: A “database of programmable resources;” Move; “[p]erhaps the network as a whole can switch to proof of stake, but in order for the stablecoin peg/basket to be maintained, some set of entities must keep a bridge open to the traditional financial system. This will be a persistent point of centralized control via the Libra Association”; not a blockchain, the “data structure of the ledger...

NZZ, 10 July 2019, with Corinne Zellweger-Gutknecht. PDF. Libra is supposed to be backed; the returns on the securities backing it are going to be distributed among the Libra partners; and Libra’s price is supposed to be managed by a network of market makers. We don’t know much more. Will market makers have the incentive to deliver? See also the longer article in Jusletter.

Finanz und Wirtschaft, June 29, 2019. PDF. It is not central bank digital currency (CBDC) per se which might act as a game changer in financial markets. What will be key is how central banks accommodate the introduction of CBDC. In principle, this accommodation can go very far, to the point where the introduction of CBDC does not affect macroeconomic outcomes. But such complete accommodation is unlikely. On the one hand, central banks will want to exploit the new monetary policy options...

At the conference of “Positiva Pengar” and “Monetative” in Stockholm, I argued that it is not so much the introduction of CBDC which would make a difference, but the policies accompanying such an introduction. This view is backed by research of Markus Brunnermeier and myself, as well as by myself. Many of the proponents of the sovereign money movement appeared open to the argument. Some of the followers, however, did not; they associate CBDC with many benefits that money, in whatever...

NZZ, April 25, 2019. PDF. Modern monetary theory (MMT) is neither a theory, nor modern, nor exclusively monetary. I discuss fallacies related to MMT. Dynamic inefficiency requires permanent, not transitory, r<g. For now, policy makers should rely on common sense rather than MMT.

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.
