Why Care About Debt-to-GDP? (nber.org)

(Friday January 09, 2026 @11:45AM (msmash) from the closer-look dept.)


Abstract of [1]a paper on NBER :

> We construct an international panel data set comprising three distinct yet plausible measures of government indebtedness: the debt-to-GDP, the interest-to-GDP, and the debt-to-equity ratios. Our analysis reveals that these measures yield differing conclusions about recent trends in government indebtedness. While the debt-to-GDP ratio has reached historically high levels, the other two indicators show either no clear trend or a declining pattern over recent decades. We argue for the development of stronger theoretical foundations for the measures employed in the literature, suggesting that, without such grounding, assertions about debt (un)sustainability may be premature.

What happens when interest expense exceeds 50% of tax collections? The U.S. government's interest expense consumes a significant chunk of its revenue, recently reaching around 19% of all federal revenue in FY 2025, with projections suggesting it could rise to 27% by 2035. Maybe we can support all of that debt, but we won't have any more government spending programs.

Total government spending federal, state, local in total is around $10T with $7T of that being federal spending. There are 133 million households in the USA. Now divide. That works out to $75,000 per household per year in government spending. The US median household income is $83,000.

Does anyone really think we need more government spending? Maybe the problem is that the existing spending is not being effectively utilized.

You are comparing mean (simple average) spending with median income. Mean income is higher than median income due to income inequality.

No it doesn't. Households do not carry the entire burden of government spending, the government has many sources of revenue other than taxation of private citizens.

Your child may have received a dollar from the tooth fairy last year, but that doesn't mean that there is $10T in government spending per tooth per year. The math may work but it doesn't say what you want it to.

That's false. Republicans run up the debt so they can look good while in power, then campaign against the debt when they aren't. It's called "two Santas" and it a primary foundation of their strategy. Generally speaking, Republicans raise debt by lowering revenues, not through increased spending, although they like military spending.

i don't think increasing defense budget by 50% could be considered "debt management", and that would be the icing on the cake. also, you can't really live on debt indefinitely if one third of your bonds are held outside and are shrinking and uncertainty makes finding creditors progressively harder and interest rates higher. all of which would seem to point to the latter, a reset, and particularly in the form of war, which would inevitably be global. two birds one stone if it works out. a total clusterfuck i

Sorry can't get behind using interest in a measure of indebtedness because its already the mix implicitly.

More debt generally should be more GDP in almost all cases, other then perhaps paying tribute to another nation or something, and more debt is generally always going to mean more interest unless people are lending for free. So the two are really coupled in exactly the same way the more traditional measure debt-to-GDP are.

Instead of interest on its own, how about the percentage of your tax take that's required to pay that interest?

If that percentage gets too high, then people just see you taking loads of tax off them, but "nothing" happening in return - which means pitchforks and lynching. If the percentage is too low, then you're perhaps missing an opportunity to invest in some infrastructure that would get your tax take higher and ultimately result in a *lower* percentage, even though your national debt was actually higher

Not a bad plan but we could get the same impact just showing tax pays what portion of federal revenue was used to pay interest on debt. I guess that is not entirely accurate as there are federal revenues that we don't nominally consider taxes, but that is pretty small portion.

It might not matter much either as its all fungible. It looks for FY2025 (ended in October) about 19 cents of every federal dollar went to interest. So you could reasonably claim that 19% of everyone individual liability goes to inte

The system will balance it self out. If you don't charge taxes for government spending, it will end up as debt and then they can use inflation to devalue everything else to 'tax' money for the spending. The nice thing about it is you also tax everyone who holds a dollar, including billionares and those outside of your country who hold dollars.
