April 21, 2021, Paper: "Faced with a global natural catastrophe, countries must spend to deal with the immediate crisis, and to reduce longer-term economic scarring. Sustained infrastructure and education spending can help counter headwinds to the long-term outlook. However, the fact that government borrowing rates are at extremely low levels does not imply that the very high debt, especially short-term borrowing, is a free lunch. Real borrowing rates are likely below long-term trend, and there is no guarantee that any future adverse shock can only lower interest rates. Massive underfunded old-age transfer and support programs are a form of hidden non-market “junior” debt."
