An auction-based sovereign debt restructuring mechanism
My "Proposal for an auction-based debt restructuring mechanism" originally appeared on VoxEU. Since publication, I've had illuminating discussions with various stakeholders which has led me to add a postscript (containing additional thoughts) to the original piece. The combined document is available here. A simple Excel workbook containing an example of how the market clearing process works, can be found here
