Making Goldilocks Happy

We have calculated that an increase in annual long-term economic growth of just a quarter of a percentage point could set in place a virtuous circle that would lead, after ten years, to a decline in the public debt-to-GDP ratio by 6 percentage points. This is because higher growth makes it easier to run a primary surplus and lowers the public debt-to-GDP ratio directly. This in turn lowers the interest rate, which in turn boosts economic growth.
