These are 10 of my favourite #UrbanEconomics articles published in 2020, in alphabetical order by author, continuing with a tradition from the last couple of years

 1) @TrebAllen, Arkolakis & Takahashi, JPE. Shows key theoretical properties & predictions of large class of trade/geography gravity models depend on 2 parameters: elasticities of supply and demand. Proposes IV estimation strategy relying on GE structure https://t.co/5On1AQkbeP
2) Ambrus, Field & @rmgonzalez046, AER. 1854 London: prices fell in blocks served by well transmitting cholera. Differences persist. Model: tenants change as contracts expire, -ve externality of poor tenants, shock makes landlords persistently target poor https://t.co/6uaxjG6Bmf
3) @kon_buechel & @maxvehrlich, JUE. More sociable individuals sort into cities. Even after accounting for sorting, those in denser areas call each other more often & longer, suggesting complementarity between face-to-face and phone interactions https://t.co/bymmL4PzaJ
4) @CarozziFelipe, JEEA. Shows how credit constraints affect composition of housing sales & access to home-ownership by the young. Neat model of housing markets as ladders with young in cheap units, possibly trading up as they age, post-2008 UK evidence https://t.co/PCn7w35Qu8
5) Harari, AER. City shape matters. More compact (circular) Indian cities grow faster (IVs compactness with mechanical expansion + geographic constraints). Compactness affects road network, location patterns, quality of life. Regulations affect shape https://t.co/TbXX9X4qwC
6) Heblich, @ReddingEcon & Sturm, QJE. Uses quantitative urban model & spatially disaggregated data for London 1801-1921 to explore how steam railways triggered workplace-residence separation, enabling substantial agglomeration in production & residence https://t.co/Z0CnPlQnMY
7) Liu, Rosenthal & Strange, RSUE. Agglomeration in tall buildings depends on street access, height amenities & productivity. Ground & high floors most valuable. Density & law firm sales indicate strong same-floor spillovers quickly attenuating vertically https://t.co/YxXFQ4yydZ
8) @OtoPeralias, JDE. Explores origins of settlement patterns exploiting spatial discontinuity in insecurity in medieval Spain. Frontier warfare encourages population concentration in few livestock-oriented (vs. agriculture) settlements, strong persistence https://t.co/FkXwJ9EohA
9) Owens, @HansbergRossi & Sarte, AEJEcPol. Rationalises healthy Detroit CBD surrounded by vacant land through model with residential externalities leading to coordination problem, evaluates development guarantees & other alternatives https://t.co/WMQiUhWf46
10) @piazzesi, Schneider & @stroebel_econ, AER. Housing search model with many segments, agents with different search ranges, broad searchers that narrow down by segment inventory. Helps think about Beveridge curve, scope & connectedness in housing markets https://t.co/wmpnDqsoL1

1. HUGE DISCOVERY!

What would have been exposed if @GenFlynn hadn't been impeded by corrupt FBI, DOJ and the Obama White house?

He'd have exposed CHINA and their laundering of IRANIAN OIL MONEY!

Read the thread below for the back story on how they went after Flynn.

1/ 2017 vs 2020 Economics

Whatever the many reasons for the coup. The aftermath has been an economic disaster. This is instructive, since Mugabe was a monumental failure in Economics.

I wish to stick to economic facts &figures. I restrict myself exclusively to GOZ & RBZ stats

2/
To be fair to Mnangagwa, as President he is fed a lot of misinformation & politically convenient gibberish by those closest to him & security clusters bent on personal enrichment than national well being.

I say this, because some of the issues are too simple to understand.

3/
Mnangagwa can never commit harakiri ( Japanese suicide by cutting one’s belly) if facts & figures were honestly presented to him. Yet we saw Mugabe commit harakiri. He died a sad death while his lieutenants are now in power. Where the lieutenants honest to Mugabe...

4/
Chinamasa was Mugabe’s finance Minister. Was he frank & honest? If so why would he benefit from Mugabe’s ouster? The same is true of Mugabe’s bureaucracy. Most benefitted from the coup. So we ask if they were honest with him during his reign?

ED suffers the same problem

5/
On Wallstreet, CEO’s are not protected from their critics & independent research. Often they rely entirely on this research & seek it out in developing their strategy.

Once, Patterson Timba kicked out an analyst from his investor briefing. Forgetting strategy is in critique

My friend @itsafronomics wanted to know the breakdown of student debt by income, so I pulled data from the SCF.

Student debt is more concentrated amongst high earners, but disproportionately amongst Black borrowers. The plot below plots the average within Income Quartiles.
1/n


But those are the averages. What's the share that's above 10k? (This is the Biden current cutoff for debt forgiveness, so a useful benchmark).

For comparison, 20% of white Americans have student debt, and 31% of Black Americans.


Let's contrast that with say, above 20k. I was surprised at how high the share remains.


When we get to 50k of student debt, or more, we see it's only about 5% of the US, and around 8% of Black Americans. Strikingly, it's a huge share of high income Black Americans (this is a known fact in the education literature, I believe).


So what does this look like put together? Overall, we see a higher share of Americans with debt above 10k, and 20k. We would cover a decent amount with 10k, but miss Black Americans especially.

To see how the innovation economy has left much of the US behind, we traveled to the small town of Bryan, in northwestern Ohio's Williams County. This is a thread about how to fix what the innovation economy broke about America.

This is Valerie. She’s 46 and has worked all her life—three jobs currently—yet she has just $65 in her checking account. Her husband works full time at a metal fastener plant.


Altogether, after health insurance premiums but before taxes, Valerie and her husband make about $45,000 a year.

The story of her working life is also the story of Bryan. The town is broken in some of the same ways that much of the rest of the country is broken. Understanding what broke Bryan is crucial to understanding how it might be fixed.


For decades, America’s political and business leaders acted as if places like Bryan didn’t matter.

I’m beginning to think that the left has been too obsessed with GDP as a broken economic metric governing the global shitshow, when inflation is more insidious. Deflation may be a more radical demand than degrowth. Burst bubbles. Deflate the price of fossil fuel infrastructure.

It’s amazing just how much political economy is still determined by the threat of stagflation. This has created a weird metonymy in which as long as you’re fight inflation (preserving the interests of (older) savers) you’re also fighting stagnation (supporting (younger) earners).

To some extent the residual fear of deflationary spirals lies behind this, waiting in the wings for any suggestion that stagnation must be fought with deflation. This is entirely understandable, as uncontrolled deflation hits the poorest hardest.

The assumption that conjoins these fears into an engine of unbridled economic stagnation is that there’s a unitary market effectively mediating between the markets in different sectors, be this unity micro-economic or macro-economic in flavour. But this just isn’t how it works.

There is so much more logistic friction in the price system than the popular story of just in time production suggests, not least in the concrete details of differentiated trade between economic actors from local businesses to nation states.

Strange things are afoot at the Circle K. Let’s sort it out.

[THREAD]


1/ Two nights ago, Rupert Murdoch called on Mitch McConnell, after hours. Since then, two Fox News-related Twitter accounts have not tweeted.

2/ Trump fired Sessions on Wednesday, replacing him with human dildo/Putin collaborator Matt Whitaker. Sessions had asked to stay until Friday and was told to leave immediately. So there was clearly some urgency to install the dildo...er, puppet.

3/ The Democrats won the SHIT out of the Midterms. Come January, the House check on Trump will leave him so hobbled, he’ll be like the dude from Misery.

4/ Trump went to Paris, ostensibly for an Armistice Day centennial event. He skipped the event, and much of the dinner tonight, because of “weather,” which everyone seems to agree is a bullshit excuse.

For fun I made a Robinhood account. It took me 5 minutes to sign up, get approved and transfer funds for trading...

Here's some details... Read on.

...it took me another 5 minutes to get qualified for options.

If I share a sign up I get "free shares" and I can share as much as I want up to 500$ worth.

The main UI has a prepopulated "list" of stocks/crypto to watch and links to news.


Clicking a stock opens a "trade" button that looks like this.

Notice options is first, buy second.

Options took me to an approval process (which took about a minute) and now away I go trading Baba options.


Buying stock looks like this. It emphasizes fractional shares.

1/ So here is a thread on how I turned $32,000 into $1.2m and back to pretty much zero (once taxes are paid).

Just note, I am not bitter or salty in any way at all, the last 2 years have been an amazing ride - travelled the world, been wealthy, been poor.

2/ Dec '16, my advertising agency folded, I had a little bit of money left and I put $32k into Bitcoin and Ether. As it started to go up I diversified into everything, Monero, Dash, this that, any crap - even Ripplecoin. Everything just kept going up.

3/ By March I think I had around $300k and $500k by the summer. I used to take 25% out but towards the end of the summer I got greedy and put it all back in and by December it was $1.2m.

4/ Thinking I was an absolute genius I decided to start a bunch of businesses. As silly as it sounds I had this goal of making $5m as I wanted to buy Bedford Town Football Club and get them in the league, and as Crypto was going up forever I needed 6 months.

5/ So:
- Trading (income 1)
- Podcast (income 2)
- Mining (income 3)
- Mining pool (income 4)
- Consulting (income 5)

Yes - all of the above as a one-man army :)

1/OK, I should really write another thread about university-centric regional development, because I think people often make some (very understandable) mistakes when thinking about this issue.

2/The biggest myth, I think, is that universities help regions by educating locals as undergraduates.

Skeptics of universities say: "But most of the people who graduate end up leaving."

3/In fact, most of what a university does for a regional economy is NOT about educating local kids.

Educating local kids is good for the nation, but doesn't help a region much.

The way a university helps a region is through

4/Undergraduates usually leave town after graduation.

But university RESEARCH pulls in OTHER smart people from other regions, and they stay there.

Here's a paper showing that this is the main way universities increase a region's human capital:

5/Research also pulls in business investment.

Companies want to partner with university labs, so they can commercialize the technologies the labs produce. So they invest in the labs, and sometimes they even put their offices in the town.
