So, what's up next in the 🇪🇺🇺🇸 sanctions against Putin's 🇷🇺?

In 1st stage, it was necessary to focus on finance (#SWIFT and all that) to quickly frontload the pain, as explained in this great🧵by @SonyKapoor

But that won't be the end. My thoughts (1/n)

Like Sony & @adam_tooze, I also think that oil/gas/coal exports are in spotlight soon

- Either Putin stops their delivery; that's the only econ retaliation he's got

- Or 🇪🇺🇺🇸 impose embargoes to drain the daily FX flows which help funding his war /2

We haven't seen action on this front yet. Transit volumes of Russian gas through Ukraine are even *up* ever since the attacs

Check this great source @Bruegel_org :
bruegel.org/publications/d…

So, are we stuck in an "equilibrium of scare" to sustain 🇷🇺 energy vs. 🇪🇺🇺🇸FX flows? /3
Not sure. Many military experts expect the war to enter an uglier phase soon, in which case the pressures to end those trade flows (which effectively "finance the war") will inevitably built up.

What would be the effect on 🇪🇺🇺🇸 economies? /4

One thing's for sure: energy prices would skyrocket

It's reflected already in prices for gas futures (see theice.com/products/27996…) but need not stop there as the discussion on trade disruptions heats up

And remember: it would come on top of the high inflation we already have /5
What to do? Govs already enact emergency plans to substitute Russian energy. Speeding up rollout of renewables is a must, delaying nuclear exit maybe too, etc.

But in the short-run, all of that won't be enough. We need to get our hands on coal & gas. /6

That's not an impossible task, as explained in this great @Bruegel_org piece. But it's daunting and could even involve demand curtailments by shutting down some industries for some time.

However, one thing might play out in our favor: trade diversion /7

bruegel.org/2022/01/can-eu…
At the end of the day, when flows 🇷🇺->🇪🇺🇺🇸 stop, FX-desparate Russia will sit on a lot of supply that it'll need to sell somewhere

Obvious candidate is China 🇨🇳, which doesn't yet impose sanctions

How quickly that can happen is unclear, as redirecting energy flows isn't easy /8
You need infrastructure, pipelines,... But key for us: as 🇨🇳 buys more oil&gas from 🇷🇺, it'll buy less from other origins like Australia, Indonesia etc.

After all, global energy demand hasn't really changed because of the war. /9

We need to make sure to get our hands on those "freed up" capacities.

The better this works, through futures contracts and by securing shipment routes, the smaller will be the inflationary jump of energy prices in 🇪🇺🇺🇸 which harms all of us (and esp low-income families). /10
That should be one key priority right now, and @BMWK and others are already working on it.

The current setting, where we're in a severe conflict with Vladimir Putin but still do business with him, is pretty fragile - both from an economic and an ethical point of view. /END

Vladimir Putin is meeting his team of economic advisors just now - in THIS very setting

It will be a fruitful and open exchange for sure...🤪
Vladimir Putin: "We'll never run out of money because my central bank can always print new Rubles. We'll be fine, regardless of the sanctions! Does anyone have a different opinion? Then speak out NOW!"
Disclaimer, before anyone takes this for granted: the quote is, of course, just satire. But the pics seem to be for real.

Dieser Tweet vom Dienstag hat sich schneller bewahrheitet als gedacht

Der @Bundeskanzler und FM @c_lindner haben heute zusätzliche Verteidigungsausgaben i.H.v. 100 Mrd Euro angekündigt. Geschehen soll das über ein "Sondervermögen".

Was bedeutet das für die Schuldenbremse? (1/n)
Wir müssen die Details abwarten, aber ich sehe 3 Möglichkeiten:

1) die BR nutzt den auch 2022 bestehenden Ausnahmetatbestand der SB, besorgt sich die 100 Mrd. Euro, parkt sie in einem konventionellen Nebenhaushalt und gibt sie im Zeitablauf aus. (2/n)

Dann würden sich dieselben verfassungsrechtlichen Fragen stellen wie schon beim Energie- und Klimafonds: darf man die Corona-Ausnahme nutzen, um sich Geld für andere Dinge (jetzt: Verteidigung) zu besorgen?

Das zu argumentieren, dürfte schwierig werden. (3/n)

The idea to freeze the ~$600bn currency reserves of the 🇷🇺 central bank, currently discussed in 🇪🇺🇺🇸, is the true „nuclear option“

It‘d be very effective in sending ruble & economy down the drain

But be careful: it’d change the global financial world forever (hear the 🔔 in 🇨🇳)
This brilliant piece by @adam_tooze , published less than an hour after my tweet, makes the same point and explains the issues in detail.

And by calling the CB reserves freeze a „full-scale financial war“ it refrains from using the nuclear analogy, which I should’ve done as well
Wow, yet another 45 minutes later this happens… things are moving very fast now

Das hier ist alles (!) zum Thema 🇪🇺 Fiskalpolitik:

"Der Stabilitäts- und Wachstumspakt hat seine Flexibilität bewiesen. Auf seiner Grundlage wollen wir Wachstum sicherstellen, die Schuldentragfähigkeit erhalten und für nachhaltige/klimafreundliche Investitionen sorgen...
...Die Weiterentwicklung der fiskalpolitischen Regeln sollte sich an diesen Zielen orientieren, um ihre Effektivität angesichts der Herausforderungen der Zeit zu stärken. Der SWP sollte einfacher und transparenter werden, auch um seine Durchsetzung zu stärken...
Wir wollen die Wirtschafts- und Währungsunion stärken und vertiefen. Wir wollen, dass mit dem Wiederaufbauprogramm ein schneller und zukunftsgerichteter Aufschwung nach der Krise in ganz Europa gelingt. Das liegt auch im elementaren deutschen Interesse."

Some good news

"Matching in Cities",
by Wolfgang Dauth, Sebastian Findeisen, Enrico Moretti and Jens Suedekum

has been accepted for publication in the Journal of the European Economic Association @JEEA_News

Paper: drive.google.com/open?id=1oWBLa…

🧵 (1/n)

voxeu.org/article/assort…
It all starts from these 2 graphs:

- Wages strongly differ across regions, mostly btw East and West, but also within West
- those disparities have grown a lot over time

For instance, Munich wages were ~30% above average in the 1980s, but >50% in 2014.

Why is that??? /2
Prominent explanations for this "urban wage premium" include

- compensation for higher local prices
- sorting: more productive workers & firms self-select into cities
- agglomeration economies: cities make workers more productive, e.g. as knowledge is concentrated there

Nein, die carbon border tax muss keinen Handelskonflikt auslösen!

Sie verschafft der EU keinen unlauteren Vorteil ggü Handelspartnern, sondern mindert bloß die Nachteile, die sich für die EU aus steigenden CO2-Preisen ergeben. Grund für Vergeltungszölle bietet sie nicht /Thread
Ein fiktives Beispiel zur Erläuterung

- mal angenommen, in der EU läge der CO2-Preis bei 100 Euro/Tonne, aber in allen anderen Ländern bei 0.
(diese Zahlen dienen nur zur Veranschaulichung und sind nicht real!!!).

- Offensichtlich hätte die EU-Industrie jetzt ein Problem. /2
- Sie hat höhere Produktionskosten als ihre Wettbewerber aus 🇨🇳,🇺🇸,🇮🇳, ... und büßt global Marktanteile ein.

- Einige EU-Firmen werden ihre Produktion ganz ins Ausland verlagern, um CO2-Preise zu umgehen. Das ist das sog. (direkte) "carbon leakage" Problem. /3
