People are purportedly losing faith in the value proposition of a college degree, however, it is simultaneously true that:
1. the price of tuition has been falling rapidly relative to CPI
2. the college wage premium has been pretty flat
so it might be a particularly *good* time to go to college?

aside from being a chart crime, I'm think the answer to "why are fewer people living in extreme poverty in china than the US" is "the data aren't comparable".
China is reporting 0% extreme poverty in a consumption based survey; the US reports ~1% in an income based one. *Sweeden* reports a 0.75%.

the long view of shelter inflation also makes a much stronger case for the primacy of supply constraints in determining housing affordability
if you think the stagnation + drop beginning in the late 1960s reflects adoption of growth controls, that's kind of the whole story!

People seldomly make this point correctly, but you can make a mostly-coherent argument that if you look at income gains in terms of the prices of "essentials", they're somewhere between modest and stagnant, depending on which year you pick for your base.

the substack guy is basically cribbing his numbers from MIT's living wage calculator (although he's disingenuously not adjusting his income numbers inline with his expenses).
it's fine to use a higher threshold for poverty. but do this consistently! it'd imply like 90+% poverty rates in the 1950s

if you think poverty measures should be updated using an inflation index that takes into account a wide variety of goods and services (weighted based on what people spend their money on), that's how the poverty measures are updated in practice.
that food % declines as ppl get richer is Engels law.

130K for a household of 4 is about what you get using MIT's living wage calculator (e.g., Hennepin County, MN).
The issue is that this is *definitely* not a poverty wage; per MIT poverty is ~32,000 in MPLS.
people have lost sight of how poor the US was when the poverty line was first introduced.

here's a fun game to play in light of that (bad) substack on "poverty" going around.
The game is called "the median household of four is rich beyond your wildest dreams".
America is really rich! median household of 4 in seattle is at like 160K.

I think this is mostly San Francisco finally shrugging off the pandemic, but it is *really* funny that rent prices in San Francisco shot up *immediately* after the city banned RealPage and other algorithmic price setting software.

niche tweet alert: NYCs "supermarket needs index" seems kind of bad. TLDR; people are calling it a "food dessert map", but the methodology makes it clear it's mostly a map of poverty.
More grocery stores is good, but I think it's being kind of oversold as an affordability or an anti-poverty tool

Rent prices remain super elevated in areas hit by the 2025 Los Angeles Wildfires, mostly driven by increases in zip codes affected by the Palisades fires.

Some takes on housing discourse:
1. measures of cost burdens at local levels are close to useless. for instance, of counties with > 100,000 renter households, the *least* rent burdened is San Francisco
2. homeownership doesn't measure what you think it does
3. housing shortage estimates are weird

per SF Fire Data, since 2003 in pre-1976 high rises (not just condos), there's been
- 0 deaths
- 20 injuries
- ~15 million in property damage (not adjusted for inflation)
This ordinance would hit 9800 units and cost 2.7 billion.

Updated plot but same conclusion:
1. Metros where more apartments use rental pricing software are more sensitive to changes in demand, but this is true for both increases *and* decreases
2. Long term prices are mostly going to be determined by at what rent the marginal unit pencils at

Anyway, I think the correct read on ticket pricing is that, pre-COVID, sports tickets track GDP and concert prices track GDP / capita.
Big picture, the rise in ticket prices seems like a combination of income inequality and supply constraints more than it does anything else (eg ticketmaster).

Re the "regulate the price of beer" debate, the two competing worldviews seem to be:
1. you can regulate margins/conduct and companies will, to a large degree, just take it on the chin
2. companies will adjust to your regulation and, to a large degree, offset what you're doing

Mostly focused on impacts on prices, and whether institutional landlords are killing homeownership and driving up rents.

new-ish working paper on Los Angeles' mansion tax argues that the revenue estimates are severely overstated.
the paper argues that somewhere between 2/3 and *all* the direct revenue generated by the tax is offset by tax decreasing transaction volume.

median house price to full time wage ratios continue to fall. obviously interest rates are higher than pre-COVID.
big difference is interest rates are way higher now, but affordability does seem to be improving

you can see this today. right now, you can get good deals on very labor-intensive (often hand welted) shoes from Indonesian bootmakers
The reason they can make those shoes is that their wages are low. When Indonesia gets rich, these deals will stop. And that will be good.

also, the reason why a very labor-intensive product (welted shoes) were cheap is because everyone was really poor, and so you could buy someone's labor (time) for not much money.
the reason goodyear welted shoes are relatively more expensive is, paradoxically, because we are rich

nerdy, but i figured out what i dont like about JCHS' residual income chart. this chart is just saying that rent has increased faster than overall inflation
the issue is that by fixing the income bins, you've removed any impact of income growth since the % of people in each bin changes over time

as a matter of pedagogy, i think teaching perfect competition first is giving people a false sense of how neoclassical econ thinks of pricing
the benefits (you can aggregate things nicely) dont matter because undergrads dont care about nice aggregation! just teach monopolistic competition first IMO

I am *really* struggling to see how this isn't bog-standard neoclassical pricing. even in perfect competition, the firm sets prices as a markup over marginal cost. the difference is just that the markup gets driven to zero by competition.
