They derive optimal fiscal policy under tax and debt limits.","gist":"The paper models optimal public investment and fiscal policy for countries with limited tax and debt capacity, and asks how borrowing should be used for recurring spending versus public infrastructure.","meaning":"In the model, recurring public spending such as law enforcement makes the economy more productive. The claim is that it should still be paid for out of current revenue and not by borrowing, because rising debt would reduce welfare and growth. This matters for governments with limited tax and debt capacity, since it separates spending on recurring services from spending on lasting infrastructure.","findings":["Optimal policy keeps the debt-to-GDP ratio constant, and current non-durable public goods should be financed only from current revenue.","For public infrastructure, borrowing may help the economy reach its long-run optimal growth path faster.","With either a binding debt limit or solvency-constrained borrowing, a more patient country has a higher steady-state growth rate but a lower public-to-private capital ratio."],"terms":[{"term":"CRS endogenous growth model","means":"A model with constant returns to scale in which the long-run growth rate is determined within the model itself, not by outside factors."},{"term":"flow of public expenditure","means":"Recurring government spending on current services, such as law enforcement, as opposed to building a lasting stock of infrastructure."},{"term":"debt-to-GDP ratio","means":"Total public debt divided by the size of the economy's annual output."}],"basis":"abstract","abstractFrom":"openalex","model":"claude-sonnet-5-5","writtenAt":"2026-10-14T05:17:18.243Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-14T05:17:18.243Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
