All the countries around Europe are either in the EU, wanting to join, or have trade agreements.
I'm talking about the World - I'm not trying to cherry-pick just the EU. Even within Europe, smaller countries like Sweden and Holland and Luxembourg appeared to be doing fine in comparison to larger ones even before FOM and the single market etc. came in. And outside the EU, there's no indication that smaller countries systematically become progressively poorer than larger ones in similar regions and with similar standards of governance.
So I don't think there's any evidence there to prove or disprove your theory about smaller countries being equally viable, but there's a lot of evidence that those countries see a benefit in being part of a larger collective.
I would say there is evidence that comes from this: Consider that, if smaller countries really were less viable than larger ones and therefore consistently became poorer, that would be a very significant thing for all countries' economies: There's no way it wouldn't have been noticed, remarked on and become - amongst economists - a well recognised fact. But it hasn't been (other than that really tiny and remote countries - ones that are basically islands in the middle of the Pacific - tend to struggle). I read extensively and I've never seen any suggestion that smaller countries generally perform worse. So I think we can conclude that, assuming there hasn't been a massive failure of analysis, it's very likely that, once you're in the range of > 1-5 million population, country size has very little impact on long term economic performance; that very much undermines any argument that the UK is somehow economically less viable outside the EU.
Yes a company trading in a larger market is more likely to face competition, but can also exploit economies of scale. Having a free competitive market, and being able to access market leading products whatever country they are made in, is better for consumers too.
Economists do recognise diseconomies of scale too. In reality, you're correct to point out that economies of scale are important, but the other side is that the bigger the area covered by a single authority/single set of rules, the more remote those in charge and the rules tend to become from local conditions on the ground, and you also have things like bigger organisations becoming more bureaucratic and less efficient because it's harder for one person to understand everything that's going on etc. I would speculate that that is a big factor in why larger countries/groups of countries don't necessarily do better.
Well the deputy governor of the BoE clearly things so, and will have access to much more data than a simple year-by-year graph. If you don't believe him then there's probably not much I can say to convince you.
Well I guess we're even then on disbelieving people: The link
@JamesT quoted in post #5753 (
https://www.bankofengland.co.uk/explainers/will-inflation-in-the-uk-keep-rising) clearly showed that the experts at the Bank of England apparently do not consider Brexit to be worthy of consideration as a major factor in the UK's ongoing inflation rate, and your subsequent reply indicated disbelief. So I could counter with,
If you don't believe them, there's probably not much I can say to convince you
Or we could both be a bit more grown up, and mutually accept that it's worth listening to what people who are experts in their field say, but that shouldn't stop us from also questioning and analysing for ourselves and having discussions like this one.
It follows from the above two premises, neither of which you choose to believe.
As far as I'm aware, I don't
choose to believe stuff. I believe stuff if the evidence I see leads me to conclude that stuff is likely to be true. I would imagine the same is (hopefully) true for you.
