11.07.2025 15:49 β π 0 π 0 π¬ 0 π 0I'm skeptical that such a model would be supported empirically, but I wouldn't be shocked if well-intentioned policy makers had some version of that model in mind (formal or not, consciously or not) when choosing to enact the subsidies.
18.06.2025 11:10 β π 0 π 0 π¬ 0 π 0Third guess, I could imagine a model where the advantage of being the "top" industry has such a large prestige benefit in attracting talent and capital that it might even be economically beneficial to keep pouring money into your winner to keep it on top.

18.06.2025 11:10 β π 0 π 0 π¬ 1 π 0My second guess, and I think this is a weaker explanation, is that there is a "prestige" benefit to having the "winning team." It feels good to the people of a country to have an industry that dominates the world, subsidies from the government to maintain that dominant position are ...

For the industry, the lobbying costs are low, the return from subsidies are high.
Second, given that it's a dumb use of resources, why do countries engage in it?
My first guess would be a Public Choice Theory explanation - an already successful industry has the resources to lobby for subsidies, a developed country has a lot of subsidies they can give ...
... but surely the marginal dollar spent on Industrial Policy for an industry that has already won a) would get a better return basically anywhere else, and b) wouldn't be invested in more productivity, but passed through directly to shareholders?
Am I missing something?
... an industry that's already won?
It's already going to be on the frontier of technology, it will already have accumulated the physical and human capital it needs, it's already benefitting from attracting investment.
I haven't worked this out formally (and suspect someone else already has) ...
... market figure out which industry your country has a comparative advantage in.

But if you're already a wealthy, developed country, why would you pour resources into ...
... and so a developing country, lacking in private capital, might try to jumpstart that process.
The caveat being it's very hard to know in advance which industry is going to be a "winner," and since any industrial policy will hurt all your other industries, it might be better to just let the ...
First, this seems like a dumb use of resources.
I get the argument for Industrial Policy for a developing country trying to nurture an infant industry.
Higher-productivity industries require concentrations of skill/capital that can be hard to start up...
"In the third part of the paper, we show three new takeaways about contemporary industrial policy practice. First, industrial policy represents a significant share of policies in the GTA (44β63% of policies with identifiable goals), with prevalence rising steadily since the 2010s. Second, industrial policies, unlike other policies in our data, disproportionately target sectors where a country already holds a dominant position in export markets. No similar targeting pattern exists for non-industrial policies, indicating distinctiveness not only in declared goals(by construction) but also in implementation. Together, these results demonstrate that industrial policies are both quantitatively important and qualitatively unique. Our third takeaway is that contemporary, real-world industrial policy deviates from conventional wisdom. Although early empirical work focused on tariffs, we find that subsidies and export-oriented measures are far more common. In fact, import tariffs are not among the most-used industrial policy instruments. Furthermore, the overwhelming majority of import tariffs are not used for industrial policy reasons. Taken together, this shows that tariffs are a poor measure of industrial policy. Similarly, in contrast to its traditional emphasis in development economics, our findings suggest that industrial policy is more widely used in high-income countries relative to developing economies. Thus, contrary to much recent literature evaluating individual episodes of industrial policy, the typical industrial policy today is not used by a country behind the technology frontier and is not targeted towards an infant industry. In fact, the opposite is true: the typical industrial policy today is deployed by a high-income economy and targets a sector in which the country has a revealed"
I'm skimming it now instead of doing the writing I should be doing, but here's my initial set of thoughts and questions.
Main takeaway: Rich countries do IP by subsidizing industries they already have a comparative advantage in.

Speaking on Squirrel Hill specifically:
Basically nada has been permitted or built since Summerset.
The Irish Center was the next big one - but we all saw how that turned out.
Squirrel Hill is zoned extremely exclusively. Basically impossible to build anything there these days.
I just emailed it to you.
Feel free to reach out if you have any questions!
Yes, please do! Our most recent data isn't on the public GitHub yet - I did some significant cleaning over December/January that isn't there.

14.12.2024 19:54 β π 1 π 0 π¬ 0 π 1An incident which struck me at the time as quite amusing occurred not long since on North Broad street. A steam shovel at work had attracted a large number of spectators, including two Irishmen, who, judging by their appearance, were toilers temporarily out of employment. As the big shovel at one lick scooped up a whole cartload of dirt and dumped it upon a gondola car, one of the Irishmen remarked: βWhat a shame, to think of them digging up dirt in that way!β βWhat do ye mane?β asked his companion. βWell,β said the other, βthat machine is taking the bread out of the mouths of a hundred laborers who could do the work with their picks and shovels.β βRight you are, Barney,β said the other fellow. Just then a man who had been looking on and who had overheard the conversation remarked: βSee here, you fellows. If that digging would give work to a hundred men with shovels and picks, why not get a thousand men and give them teaspoons with which to dig up the dirt?β The Irishmen, to their credit, saw the force of the remark and the humor of the situation and joined heartily in the laugh that followed, and one of them added: βI guess youβre right, Captain. The scoopβs the thing after all.β βPhiladelphia Public Ledger.

Super excited to publicly launch "All Day TA" (http://www.alldayta.com), a product @joshgans.bsky.social and I have been working on with our team over the last year. Short version: if you teach in spring, you will want to use this! It's the future of higher education. A short thread: 1/x
