Reinhart, Carmen M., and Christoph Trebesch. "Sovereign Debt Relief and Its Aftermath." Journal of the European Economic Association 14.1 (February 2016): 215-251.
This paper studies sovereign debt relief in a long-term perspective. We quantify the relief achieved through default and restructuring in two distinct samples: 1920–1939, focusing on the defaults on official (government to government) debt in advanced economies after World War I; and 1978–2010, focusing on emerging market debt crises with private external creditors. Debt relief was substantial in both eras, averaging 21% of GDP in the 1930s and 16% of GDP in recent decades. We then analyze the aftermath of debt relief and conduct a difference-in-differences analysis around the synchronous war debt defaults of 1934 and the Baker and Brady initiatives of the 1980s/1990s. The economic landscape of debtor countries improves significantly after debt relief operations, but only if these involve debt write-offs. Softer forms of debt relief, such as maturity extensions and interest rate reductions, are not generally followed by higher economic growth or improved credit ratings.
