We analyze retail central bank digital currency (CBDC) in a two-tier monetary system with bank deposit market power and externalities from liquidity transformation. Resource costs of liquidity provision determine the optimal monetary architecture and modified Friedman (1969) rules the optimal...

We investigate monopolistic tendencies and the intensity of currency competition on the crypto market in the light of Hayek's "Denationalization of money". Interestingly, Hayek never considered differentiation and specialization by innovative private currencies could lead lasting currency...

Many central banks discuss the introduction of a Central Bank Digital Currency (CBDC). Empirical evidence suggests that households may differ in their willingness to hold CBDC. Against this background, this paper investigates the macroeconomic effects of different CBDC regimes in a New Keynesian...

Part of the present inflation is caused by the breakdown of globalization, in particular supply chains, part is caused by the Corona Pandemic, in particular lockdowns, part is caused by the Ukrainian War, part is caused by European sanctions, and part - and not the smallest one - is caused by...

This article develops a model in which an intermediary uses a supply chain finance (SCF) program to fund suppliers. The SCF program pools liquidity from suppliers and meanwhile provides immediate payment to suppliers with pressing liquidity needs. We show that the intermediary optimally selects...

Fractional reserve regimes generate fragile banking, and full reserve regimes (e.g., narrow banking) remove fragility at the cost of suppressing the role of banks as lenders. A Central Bank Digital Currency (CBDC) could provide safe money, but at the cost of potentially disrupting bank lending....

The European Central Bank (ECB) wants to push ahead with the "digital euro" project. However, the digital euro is by nomeans the only and possibly not even a good (let alone the best) way to respond to the comprehensive change in the world of money. Interms of its reputation, the ECB must act...
