This paper examines the impact of natural disasters on fiscal and external sustainability across 134 economies from 1980 to 2023. We adopt a two-step approach: first, we estimate country-specific, time-varying sustainability coefficients; second, we assess their determinants using Weighted Least...

We use a DSGE model to study the effectiveness of green-asset purchases by the central bank (Green QE), along the transition to a carbon-free economy driven by an emission tax, abstracting from price stability considerations.
