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 payment instruments dependent on the number of...

In this paper, we develop a model incorporating the impact of financial inclusion to study the implications of introducing a retail central bank digital currency (CBDC). CBDCs in developing countries (unlike in advanced countries) have the potential to bank large unbanked populations and boost...

Due to technological change and the rise of private digital currencies more and more central banks investigate the possibility of issuing their own Central Bank Digital Currency (CBDC). This paper develops a conceptual framework, which shows how the issuance of CBDC and the provision of access...

In this study, we provide a systemic perspective on central bank digital currencies (CBDC). We separate existing proposals for CBDCs into the perspective of new payment objects, made available by central banks to a broader public, and new payment systems, operated by central banks. From a...

Central banks (CB) around the world are currently exploring the implications of issuing a new form of sovereign currency known as Central Bank Digital Currency (CBDC). Introducing CBDC is a compelling need for governments and CBs alike, as powerful private players have already taken the lead in...

This chapter provides an expository and teleological account of central bank digital currencies (CBDCs) through the prism of the eNaira, Nigeria’s CBDC. This chapter argues that the central bank’s legal authority to issue the eNaira is nebulous and the eNaira adds no unique value to Nigeria...

This study uses meta-SWOT analysis to asses the internal strength and weaknesses, as well as the external opportunities and threats, followed by the determination of most optimal CBDC design in emerging economies. In analyzing internal aspects, CBDC allows us to have an efficient payment system,...

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 analyze the impact of introducing a central bank-issued digital currency (CBDC) on the operational framework of monetary policy and the macroeconomy as a whole. To this end, we develop a New Keynesian model with heterogeneous banks, a frictional interbank market, a central bank with deposit...
