Nice article from @MESandbu. This from a theme in sellside research before Christmas. Could the pandemic break secular stagnation & deliver a decade of strong growth?

Historical evidence clear - pandemics are usually deflationary, causing lower r*. Big difference with wars, which usually cause r* to rise. Great Jorda et al paper on this https://t.co/f3a9O3Hw3c
Here is their main result
Historically, Wars destroyed both capital stock and labour force. Pandemics killed millions but left capital stock untouched. Covid-19 is neither of these things. Workforce hasn't plunged, capital stock untouched. Comparison with 1920s is a stretch. So precedent for today..
Some more recent evidence based on modern health crises shows only a short-lived boost to GDP, then weaker trend then before. See this Vox column https://t.co/NXZWP3QNlL
And their main result
The only lesson I would draw from 1920s is in the comparison between Germany/UK and France/US. The former went down the austerity route. Far from the "roaring 20s", they had a decade of deflation and unemployment. Politicians should know this by now...but maybe not 😉
So @MESandbu warns about danger of premature monetary policy tightening. But I think CBs are leaning heavily against such an error. They have internalised the 2010s, eff raising their inflation targets. The policy risk is on the fiscal side. Not sure politicians learnt anything
Bear in mind also that the 2020 recession compounded many of the underlying causes of secular stagnation: esp income/wealth inequality, corporate divergence (weak SMEs), monetary policy at lower bound and will leave a legacy of even higher corporate debt ratios

EVs DO NOT EMIT MORE PM

Recently @OECD published a report about particulate matter (PM) from road transport. Newspaper headlines blared that electric vehicles where worse than combustion vehicles. That conclusion was wrong according to the report itself.

Let me show you.


The report (published december 7) can be found here:

It's main point is well taken: as cars get cleaner, fine particles emitted by brakes, tires and road surfaces will become more important.
The table comparing electric and combustion engines is on page 92. I took averages of low and high values to get the graph in the first tweet.


I merely took the averages. To get this.


I think it is a terrific report that pulls together a LOT of literature on fine particles that cars spew into the air and that make us sick.

We have ignored this problem for too long, and there's more here than simply exhaust!
I really think people have a very short-sighted view of the city and its key role in decades to come for the economy of 🇨🇳. Every so often, people have a handful of misconceptions about the city's future because they lack of basics in strategy 👇


https://t.co/6wuRzXGkYZ The West propaganda seems to make people think we are cracking down on 🇭🇰 people because we no longer need them and we will inevitably suppress their rights. Every now and then, I talk with people in 🇭🇰 who think the Great Firewall will extend to 🇭🇰

🇺🇸-led liberal order is very strong to come across 🇭🇰 people and make them believe what they want. Brainwashed people don't think rationally and fall for the lies and propaganda. This guy is one among so many others I met in 🇭🇰 who told me the same thing, that the city is doomed

They couldn't be more ignorant ! Unfortunately they will end up leaving the city and missing out on incredible opportunities... But they don't know that nothing will eventually change after 2047 ? 🙃Let me explain you why

I bet even after 2047 🇭🇰 will still enjoy a high degree of autonomy and freedoms that its mainland counterpart can’t enjoy : an independent legal and financial system, English as one of the official language, an access to the West internet, its traditional medias, etc.
