An important feature of physical cash payments is resilience, which is due to their indifference to power outages or network coverage. Many central banks are exploring issuing digital cash substitutes with similar online payment functionality. Such substitutes could incorporate novel features,...

We study the macroeconomic effects of central bank digital currency (CBDC) in a dynamic general equilibrium model. Timing and information frictions create a need for inside (bank deposits) and outside money (CBDC) to finance production. To steer the quantity of CBDC, the central bank can set the...

This paper discusses commercial banks’ demand for central bank reserves under two alternative monetary policy framework configurations, namely: (i) an interest rate corridor system with scarce liquidity, and (ii) a floor system with ample liquidity. It outlines the interaction between the...

I provide a simple general equilibrium model of monetary policy implementation and pass-through for undergraduate and graduate teaching. Besides a household and a firm, the model features a continuum of commercial banks, a government, and a central bank. The household uses deposits and cash to...

The advent of stablecoins offers new and innovative ways to improve financial inclusion, reduce transaction costs, and increase the efficiency of the global financial system. The following paper explores the assets and process necessary for creating a central bank digital currency (CBDC) on the...

Central banks repo market operations and liquidity infusions occasion a structural liquidity mismatch in bank balance sheets and increase the dependence on central bank liquidity. This paper argues for what I term “Circular Monetary Economics”, an approach to monetary policy that seeks to...

We examine the economic consequences of an interest-bearing design of the Central-Bank Digital Currency (CBDC), and extend the discussion to an open-economy context with trade and capital flows. We use a dynamic stochastic general equilibrium (DSGE) model to simulate a baseline scenario with...

The aim of this paper is to analyze the demand of both traditional and new media of exchange – as cryptocurrencies and central bank digital currencies – proposing a novel specification of the demand for money. In this specification, the medium of payment (MOP) has three properties: the first...

We develop a New Keynesian model where all payments between agents require bank deposits through deposits-in-advance constraints, bank deposits are created through disbursement of bank loans, and banks face a convex lending cost. At the zero lower bound on deposit rates (ZLBD), changes in policy...

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...
