Few days ago, I read a write-up titled No one knows how much the government can borrow
The authors basically argues the following:
Now I am not an economist (moreover, I am rather suspicious of that discipline in general), but this topic interests me. The other day, I had a conversation with a friend who is very worried about the public debt to GDP ration of Italy and how it can negatively affect EU, Eurozone and specifically northern-EU countries (because they will pay for the lazy Italian pensions, right?). So the question arises: How much debt/GDP can Italy afford? Where is a breaking point? And what options different stakeholders in the game will have once a default of Italy is triggered?
Since in the news everybody has an opinion on this, I asked around the Intertubes and among my smart friends, naively thinking that this must be a well researched topic in that high profile discipline. After all, maybe I am suspicious of economists, but I do treat most of their work with high respect. Well, my inquiries yielded nothing useful.
So here I am asking for pointers to useful literature on the topic. What do we know about how much a country like Italy can borrow before it ends up in trouble?
@freemo Thanks for the lecture, I do understand these technicalities. Here I am interested in “applied macroeconomics” - if such a thing even exists.
Finances (and thus debt) of individuals lives in a fixed context (from their perspective). A country of certain size and standing is, however, well capable to change, or at least significantly influence the context: e.g, by printing money by mechanisms like QE, changing legal and political framework around its debt, use its trade or military gross tonnage to effectively blackmail its creditors, etc. Individuals have none of that.
At the core of any loan is in the end trust. To my understanding, a default happens when creditors no longer believe you can service your obligations. But that “feels” too weak. I would hope there’s more human knowledge on this topic.
That is why I am interested in serious literature on the topic, rather than contrived technical arguments (I have myself a full bag of those). Do you perhaps have any pointers?
@freemo Thanks for your response.
This seems like an antagonstic or atleast negative choice of words, am I misreading this?
I did not mean it anyhow negatively. Apologies. Maybe it’s just a bit late already…
@FailForward No worries, if it was not the intention then no offense assumed. I am sorry I accused you of potentially meaning it that way. I take you at your word that it was me who was misinterpreting. Ignore any such concerns, I wont give it another thought .
It can sometimes be hard to convey tone through the internet, it happens, and the fault was mine.
@freemo Thanks a lot for all the references, some titles look very relevant to what I am interested in. I will try to get out some of those to educate myself, this is useful.
Just a couple of remarks to clarify what I meant:
Me: changing legal and political framework around its debt
You: What would a countries internal laws or political framework have to do with the agreement they have with other countries regarding their debt.
E.g., Italy is a part of Eurozone. Either Italy, or other EU countries can conceivably modify treaties in a way which would influence how external actors perceive its ability to service its debt. For instance, hypothetically, by delegating some part (control?) of their internal economic policy making to the EU-level. Or similar. Of course e.g., Bolivia has fewer options in this respect.
@FailForward That would, change their credit rating yes, but two things either:
1) it is not successful as a tactic in improving the rate of growth of their GDP, in which case my original formulation holds true all the same, they will ultimately default or brought closer to default should the loan cost more money than it produces
2) it is a successful tactic in improving the rate of growth of their GDP. In which case the equation still holds true but you simply adjust it to include the new rate of growth figures for the GDP to reflect this change.
Point being no matter what changes they might make it doesnt change the fact that if a loan is not more profitable than what you spend the loan on, then that decision will drive you closer to default, not farther away.
The example you give of changing of delegating some control to the EU is something you can do regardless of the loan or not, so it would be an independent variable not dependent on the effect from the loan itself with regards to defaulting, so doesnt really get around the root problem.
@FailForward
This seems like an antagonstic or atleast negative choice of words, am I misreading this?
Agreed, though that does not change the answer, in fact I tried to point out those factors are simply incorperated into the equation.
Take for example when I said:
This factor points out exactly what you just stated, printing of money devalues you money, thus reducing its nominal value and thus would be considered as an expense on the GDP, which itself is measured nominally.
This one doesnt seem particularly relevant unless I mistunderstand what you mean. What would a countries internal laws or political framework have to do with the agreement they have with other countries regarding their debt. Whatever their agreement is, it exists outside the internal legal frameworks of each respective country.
This one makes some sense in general of course but not exactly what you were asking. You were asking when they default, obviously if you go and start a war over not paying your loan then you’ve already defaulted, the war just means that you may not be able to be strong-armed into paying it if you have the superior military might. Which is a fair thing to consider but a different question then “when do we default.
No they don’t but as we covered they are easily incorporated into the equation as each one is still measurable in similar terms as an individual.
The points I made are not my own, nor are they “contrived technical arguments”, they are mostly me just repeating what the already established studies and literature on the topic mostly agree on. I am somewhat surprised the original author, whoever they are, had such a hard time finding such studies. As someone who has worked closely as a professional on economic data and models, including along side other economists, I am merely providing the perspective of experts in the field.
Honestly your tone lately has been surprisingly confrontational and bordering on rude, though i continue to give you the benefit of the doubt that perhaps im misreading you, I do hope that is still the case.
