The economic clash between Greece and Germany is invariably portrayed as a clash of cultures. The majority of Germans resent what they see, and are assured by those who should know better, as a bailing out, at their expense, of those in the southern peripheral European countries who appear to be unable to manage their economic affairs as well as they can.

That seems a perfectly commonsensical point of view but raw ‘common sense’, as always, in economics cannot be relied upon to be the best guide. Our common sense is invariably derived from our own micro-economic experience. The principle that it is better to be in surplus than deficit, for example, works fine for us as individuals in the micro world, but taking a wider view, that commonsensical notion is inconsistent with the basic accounting principle that for every asset there has to be a debt. For every surplus there has to be a deficit. Not everyone can be in surplus and not everyone can be in deficit.
So we need to correct our ‘commonsense’. Physicists, like Angela Merkel who therefore can have no excuse, are used to doing exactly that. They know that their commonsense viewpoints of the world will only take them so far. It fails completely after that. Anyone who has studied Maxwell’s equations, Quantum Mechanics or Einstein’s Relativity knows that these subjects can make your brain hurt! After a while, we have to come to the conclusion that it is better to try to understand via the mathematics of it all rather than understand completely.
It is nowhere near as bad in economics, but still just a little lateral thought is required. The easiest way to understand what needs to happen in the single currency eurozone, is to make a comparison with what already does happen in a successful currency union.
Let’s take a look at how it all works in the USA. The United States has, as we all know, a common currency but also a Federal Government to conduct macroeconomic policy, and transfer surpluses from the wealthy parts of the US to the poorer parts. It transfers surpluses. It does not arrange loans, except perhaps for special projects. If it did, the wealthier parts of the USA would end up as massive creditors. The poorer parts would end up as massive debtors. There would be clashes between New Jersey, the wealthiest state, and Mississippi the poorest. I had to look this up , by the way. I suspected that Mississippi might be the poorest but I had no idea which was the wealthiest. I had thought maybe California. That’s as it should be. It should not be like it is in the Eurozone where the wealthy states never tire of letting everyone else know who is paying the bills.
So, imagine New Jersey providing big loans to an impoverished Mississippi, dictating that it implement privatisation of public assets at knock down prices and drastic cuts to state spending, pensions, its education service etc to be able to repay those loans. The Mississipians and the New Jerseyites would be saying exactly the same things about each other as the Germans and Greeks are saying now!
So, just as any transfer of funds between New Jersey and Mississippi has to be just that, ie a transfer and not a loan, so too it needs to be between Germany and Greece in the Eurozone.
The German taxpayers may well not like that idea. It certainly would not have been properly explained to them just what they were letting themselves in for when the Euro was created. No politician in any of the Eurozone countries would have dared make that explanation! It would have been career suicide. There were economists around who did their best to explain it all but they weren’t listened too.
It is too late for that now, but the reality of what has been created, in their name now needs to be recognised and understood by all. Some rethinking is in order. That has to start with the Germans, then the Dutch and then everyone else too. The sooner the better.

There is at last some evidence that the political mainstream is coming around to the idea that “places {in the same currency zone -PM} in deficit have to be easily financed by places in surplus”. At least there is, if we can consider John Redwood, a British Conservative MP, to be representative of the mainstream. He, himself, may well question that assertion, but nevertheless this recent quote shows that it isn’t just Greece’s Syriza and the political left who are making the argument.
John Redwood is, of course, meaning Germany although the same argument would apply to Holland who run an even bigger surplus, as a percentage of GDP than Germany. The Germans were always happy to finance their customers when they used the DM. They’d buy up the treasury bonds of the deficit countries, like the UK and US, and that way their surpluses were recycled to their customers by the process of government deficit spending. So why the problem now? From their POV now, they should be even keener to do that. It would keep “their” trade zone healthy. They could impose conditions , of course, but there would be no reason to impose such stringent conditions as they do.
They seem wedded to the idea that internal devaluations are now needed in the peripheral countries of the Eurozone. General devaluations are no longer possible within the common currency zone. But can internal devaluations work? We know external, or general, devaluations can work. Recently the Canadian dollar has fallen by about 20% against the US dollar. This isn’t particularly noticeable to Canadians until they cross the border into the US. Then they realise that their wages and salaries are now worth 20% less, in terms of US$, than before. Canadian prices, at least the ones unaffected by import costs, such as rents, in are now 20% less too. Imports from the USA are now 100*(0.2)/(1-0.2) =25% more expensive.
This shift is necessary for the Canadian economy to adjust to changing world conditions. But what would have happened if Canadians used the US$? Theoretically, if Canadians had reduced all prices and all wages by the same amount, and IF spending patterns were left unchanged, the outcome would be the same. I’ve used the big IF because IF prices were falling fast then the real level of interest rates would be very high, even if they were nominally zero, and which would make it irrational for any individual to spend more than they had to.
But would that have really happened? If Canadian companies had faced falling demands for their products, they would do what all companies do. They’d cut back. But there wouldn’t be pay cuts and price cuts. Maybe just no pay rises and no price rises. They’d lay off some of their staff and stop recruiting others. They would adjust to being 20% (or close to it) smaller in this way. That would be repeated right through the Canadian economy which would end up 20% smaller too. Unemployment would skyrocket and the US media would no doubt be making negative comments about the Canadians, especially if they’d dared say it was even partially the USA’s fault.
That’s exactly what’s happened in Greece, Spain and elsewhere. Except of course it is the Euro not the US dollar which is causing the problem. Economists, of the classical variety, will argue that this should not have happened. Some will be in complete denial and will argue that it can’t have happened, or if it has, it must be due to some other factor. Lazy Greeks maybe? They can , of course, show nice mathematical models of how an ideal economy would be able to restore its competitiveness if only people would just behave rationally – according to their definition of rationality. But real people behave rationally as they themselves see it, not how anyone else might see it. That needs to be understood by real economists too. Including real German ordo-liberal economists!
So instead of imposing austerity on countries like Greece and Spain, to force internal devaluations, the Germans need to find some new economic advisers who can come up with some other way to equalise the money flows. Otherwise, their dream of a united Europe will become ever more nightmarish as time passes.
