Construction costs are currently skyrocketing

Meanwhile, it is common in the private sector that prices are even increased retroactively. Yes, that is possible.

So I order a batch of material for 07/01/2022. One week later, the manufacturer implements a price increase retroactively as of 05/01/2022.
All items delivered from that date are subject to the price increase.

This is how it looks in reality nowadays.

Here was gibberish

Before continuing with you, please refer to this first:

One could have directed the economy into structurally weak regions. In all of East Germany, there is no DAX company. Whereas in Munich there is.

Tesla is in Brandenburg, Intel is coming to Magdeburg. What a silly narrative you are trying to feed. And don’t come at me now with: "But those are not DAX companies".
Fun fact: We proud Bavarians unsuccessfully tried to get Intel with Schweinfurt and Landsberg. Too bad, Söder/Aiwanger.

By now, it is common in the private sector for prices to be increased retroactively. Yes, that is possible.

So I order a position of material on 07/01/2022. One week later, the manufacturer announces a price increase retroactive to 05/01/2022.
All positions delivered from that point are due with the price surcharge.

That's how it looks in reality nowadays.

Blablabla. Let's stop feeding the troll. *Ignore mode ON*

Interesting to think that asylum seekers or unemployed people could simply be settled in structurally weak areas to free up housing in metropolitan areas for working people. Especially without even remotely recognizing the resulting problems. Aside from the actual possibility.

Well, there are two connections here that for some highly educated forum participants are cheap pub clichés and cannot be correct at all due to highly scientific sovereign argumentation:
1) Migration leads to increased demand for living space. This increased demand and the resulting pressure on the real estate market lead to higher prices and scarcer building land.
2) If the ECB prints money relentlessly for years, keeps zero interest rates, and buys billions of southern states' government bonds "whatever it takes," then that is eventually a reason for higher inflation rates.

Both are profoundly wrong from a scientific perspective :)

Regarding 2) I somehow feel addressed. I never said anything about 1). Let's set science aside, which is just a method and not a thing. Let's try another method, logic:

IF the current inflation is caused by the ECB's "money printing," zero interest rate policy, and government bond purchases, then logically and necessarily it means that it is NOT caused by supply chain problems and the Ukraine war along with sanctions. THEN two questions:

a) What do supply chain difficulties and war with sanction policies actually lead to on the price front?
b) Why do countries that do not have the ECB as their central bank see the same inflation?

If we compare the city of Nürnberg with Dresden, for example, the picture is confirmed.

While Nürnberg has established a foreigner share of about 25 percent, this is only 9 percent in Dresden.
There is a housing shortage in Nürnberg, whereas in Dresden there is demolition. As already described, demolition funded with considerable tax money.

The influx of migrants is largely limited to the western German metropolitan areas with their known problems regarding housing. This only worsens the problems further.

In Halle an der Saale alone, 20,000 apartments are vacant. There used to be housing allocation as well. That would be completely normal.

Decisive, however, is also the population density of a region. And here Nürnberg, with 2765 inhabitants per km², is significantly more populated than, for example, Dresden with only 1693 inhabitants per km².

Stuttgart, with 3040 inhabitants per km², has almost twice the density of Dresden. Accordingly, the real estate market is denser as well.
While a newly built single-family house in Stuttgart has become almost impossible, in Dresden one can still build almost unrestricted and relatively cheaply.

But just as a thought-provoking impulse. It is also a question of quality of life.
