Long-duration bonds and sovereign defaults

This paper extends the baseline framework used in recent quantitative studies of sovereign default by assuming that governments can borrow using long-duration bonds. Previous studies have assumed that governments can borrow using bonds that mature after one quarter. Once we assume that the government issues bonds with a duration that is close to the average duration observed in emerging economies, the model is able to generate a substantially higher and more volatile interest rate. This narrows the gap between the predictions of the model and the data, which indicates that the introduction of long-duration bonds may be a useful tool for future research about emerging economies. Our analysis is also relevant for the study of other credit markets.
