An auction-based sovereign debt restructuring mechanism

    • Please see this paper for a description of a proposal for an auction-based debt restructuring mechanism. The process can be simulated via this online application (see footnote 25 of the aforementioned paper for login details). A first, initial version of the proposal originally appeared on VoxEU.

    • A short 6-minute video explaining the idea can be found on YouTube.

  • A simple Excel workbook containing an example of how the market clearing process works, can be found here.
