The macroeconomics of central bank issued digital currencies

This paper studies the macroeconomic consequences of a central bank granting universal, electronic, 24x7, national-currency-denominated and interest-bearing access to its balance sheet via the issuance, according to well-specified policy rules, of a central bank digital currency (CBDC). To study this issue we use a monetary-financial DSGE model, calibrated to match the United States in the pre-crisis period, that models CBDC as an imperfect substitute for bank deposits in the provision of monetary transaction services, and that models bank deposits as being created through loans or asset purchases as in Jakab and Kumhof (2015).
