Most Western countries are already starting to reconsider whether Hong Kong will remain a viable trading centre.

When the entire world stops trading with HK, how will HK be the financial center of the world?
I doubt tourism would be any better in the next few years either lol
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.
I can't tell if I'm agreeing or disagreeing with @jc_econ.
There is no relationship b/w deficits & interest rates in the US & many other advanced economies. Centuries of dynamic institution building underpin our reserve currency status that allows rates to be a function of economic fundamentals, flows & policy not credit risk 1/3
— Dr. Julia Coronado (@jc_econ) January 26, 2021
Increasing government spending or reducing taxes increases demand (or reduces saving). This raises the price of loanable funds or the interest rate.
In a dynamic context, more demand means a stronger economy, the central bank raises interest rates sooner, and long rates rise.
(As an aside, we are not close to the United States needing to worry about credit risk and the risks are more overstated than understated in most other advanced economies too. But credit risk is not always & everywhere irrelevant, just look at the UK in 1976 or Canada in 1994.)
Interest rates have fallen over the last 20 yrs while debt has risen. This does not necessarily mean that debt rising causes interest rates to fall. It could also mean that other things have happened at he same time that pushed down interest rates more than debt pushed them up.
The suspects for these "other things" include slower productivity growth, slower popln growth, higher inequality, less investment, etc. All of which either increase the supply of saving or reduce the demand for investment, reducing the equilibrium interest rate.
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: https://t.co/1HpicKexOt
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!
But don’t take @ambermruffin’s word for it. You should get references...

Vol 70 Apr | '#Vote choices of left-#authoritarians: Misperceived congruence and issue #salience' by @NilsSteiner and Sven Hillen is now available @ches_data @german_gles #Germany https://t.co/pmCoP5t7CL pic.twitter.com/Vl8rCahcZL

In the data from the Campaign Panel of the German Election Study 2017, many voters prefer higher social benefits and taxes and want to restrict immigration. @ches_data show that no party bundles issue positions in this way.
In the article, we show that many such “left-authoritarians” perceive the party they voted for to also hold a left-authoritarian position. Interestingly, this includes many AfD voters who report a perceived left-wing economic position of the party.
Our statistical models study the interplay between this (mis-)perceived congruence and issue importance, using an open-ended question on the most important political problem in Germany.
We find that (mis-)perceived congruence and issue importance interactively shape the left-authoritarian vote. Simply, perceived congruence matters more on an important issue—and issue salience matters most if voters accurately perceive incongruent party supply.
They often use EROI (Energy Return On Investment) as their metric
This is a rant against these EROI people misinforming the debate, based on a rebuttal of a 2020 paper
In essence the approach of the paper is straightforward:
1) Discard water and 96% of land because it's supposedly unavailable
2) Assume solar cells on just 1/5th of the remaining 4%
3) Complain that production of solar panels takes a lot of
About 1) (available land)
Discarding 96% of land seems pretty extreme:
30% of the world's land is barren
40% of the world's land is used for meat
I think we could find more than 4% if we tried
(but we don't have to: we need less than 1%)
https://t.co/rJZiNWcu7F
About 2) (using 1/5th of available land)
If cells are expensive and land is dirt cheap, covering 20% with solar cells is logical
But with cheap cells you maximize land use: 80% is easily possible
New paper headline:
"Global available solar energy over 10 times what we need"
About 3) (20% of energy is needed for production)
This is something @MLiebreich and I often complain about:
If you get more energy out than you put it, that's FINE
If you get five times more energy out, that's GREAT
EROI is a USELESS metric. Let's STOP using it. At all.

China is building the world's most advanced UHV grid right now.
UHV lines are good for carrying power over long distances. The high voltage level reduces line loss. But they are very expensive to build.
China's UHVDC Network now:
2/14
In the rest of the world, UHV lines have generally been used sparingly. Submarine power cables (e.g. connecting UK to mainland Europe) and some huge hydropower projects in Quebec are some notable exceptions.
China is building UHV lines on a scale never seen before.
3/14
So why is China different? Geography plays a huge role. China's load centers are in the coastal East and South, while the best wind, solar, and hydro resources are in the North, Northwest, and Southwest. Power (esp. RE) is being generated far from where it's needed most.

In the past, poor regional interconnectivity has been a big contributor to low offtake levels of renewable energy. Of course a glut of coal power also played a role. Curtailment has improved in recent yrs tho. I discussed regional grids before:

First, Chinese doesn't have a national grid, at least not in the way that small countries do. There are 6 regional grids (N, NE, NW, E, C, S). State Grid runs 5 of them and Southern Grid runs 1.

UHV lines provide a inter-region backbone to transport power hundreds or thousands of km across the country. The UHVDC lines are used for the longest distances, while UHVAC lines are used for shorter distances, often within the same regional grid.
China's UHVAC lines now:

I know people think this is fun but -- why do we have a stock market? So productive firms can raise capital to do useful things. Detaching stock price from fundamental value (Gamestop is now worth almost as much as Best Buy) makes the markets serve the real economy worse.

What is profit? It's excess labor.
You and your coworkers make a chair. Your boss sells that chair for more than he pays for the production of that chair and pockets the extra money.
So he pays you less than what he should and calls the unpaid labor he took "profit." 2/10
Well, the stock market adds a layer to that.
So now, when you work, it isn't just your boss that is siphoning off your excess labor but it is also all the shareholders.
There's a whole class of people who now rely on you to produce those chairs without fair compensation. 3/10
And in order to support these people, you and your coworkers need to up your productivity. More hours etc.
But Wall Street demands endless growth in order to keep the game going, so that's not enough.
So as your productivity increases, your relative wages suffer. 4/10
Not because the goods don't have value or because your labor is worth less. Often it's actually worth more because you've had to become incredibly productive in order to keep your job.
No, your wages suffer because there are so many people who need to profit from your work. 5/10
