Understanding the Digital Euro: A Literature Review of Adoption, Usage, and Monetary Sovereign

The review discusses four studies on the digital euro: an ECB speech, a bibliometric mapping of CBDC literature, a geoeconomic analysis of the ECB's motivations, and a regression analysis of potential use. It argues that sovereignty goals depend on usage, which in turn depends on consumer attitudes. The review also identifies gaps in linking estimates to the ECB’s objective and areas which need further research.
