Short 🧵 on new NBER WP “Labor Misallocation Across Firms and Regions”. The context: a giant literature has shown that frictions to labor mobility across space lead to spatial misallocation - simply put, some people are stuck in locations where there are no good jobs for them. 1/
How labor mobility costs decrease aggregate productivity: they shield low productivity firms from competition, increase local monopsony power, and misallocate labor, from Sebastian Heise and @PorzioTommaso nber.org/papers/w30298

I am a former H1B visa holder and US citizen. When I arrived in the US in 2004 with a trekker's backpack, an F1 visa, and $2,000, I had no idea how this country would change my life. Within six years, I was hired by MIT as an Assistant Professor and within ten I had started my…
Now we have @PorzioTommaso from @Columbia_Biz delivering the keynote for @RIDGE_uy #TSG24 “Economic Development according to Chandler” @GChiovelli @bcentralchile
Job market series 2024 Wrap-up: We just finished our series of 26 posts by development economics PhD students on the job market. Here is a summary of the process and a list of all the posts in case you missed any blogs.worldbank.org/en/impactevalu…
We have an opening for a postdoc position @warwickecon for a macro-development person! This is funded by my ERC/UKRI Starting Grant - you will develop your own research agenda with no teaching or admin required. Duration: initially for 1 year, extendable to 2+. [1/2]
Last, this is why descriptive work is underrated. No preposterous IV, no incomprehensible structural model, just a new fact about the world. If the descriptive work is done well — and it is not easy — the fact permanently enters everyone's headspace and must be contended with.
Fascinating paper on where 6000 global elites went to college. Billionaires, CEOs, heads of state, central bankers, etc. In a word: Harvard. Fully 10% of global elites went to Harvard. Elite US schools are over-represented (23% IvyPlus), but nobody comes close to Harvard. 🧵
🚨The Development-Markets Initiative at Yale EGC has a 1-year postdoc for Economics PhDs focused on development, trade & markets. All research, no teaching. @PennyG_Yale , @lfbergquist, @mayara_pfs, Nick Ryan, @YaleEGC aeaweb.org/joe/listing.ph…
*Very* happy to see this 'in print'. Along with our paper "Labor Market Power", and "Merger Guidelines for the Labor Market", we present an set of tools / data / applications to big policy questions in labor markets. Its not perfect, but its a start!
In an economy with realistic firm heterogeneity, a federal minimum wage cannot meaningfully reduce the efficiency losses due to monopsony power. Minimum wages do redistribute, but at the cost of lower production. By Berger, Herkenhoff and Mongey econometricsociety.org/publications/e…
Like a winemaker, the economist will use math to produce a fine idea from the grapes of a rough insight. The math is the tool to help them think. Once the thinking is done, the reader can simply drink the idea. The curious reader may still want to visit the vineyard, see how…
“Show a typical economist a theory article, and watch how he ‘reads’ it: He reads the abstract and introduction, flips the theory pages, then reads the conclusion. If math is so enlightening, why do even the mathematically able routinely skip the math?” betonit.ai/p/economath_fa…
My Xmas wish for DOGE: please simplify the process of submitting letter of recommendation for PhD programs!
Okay, last but certainly not least, I'll tweet about another excellent student, @D__Henning. David is a development economist, focusing on firms and their interactions with regulation/tax administration. His JMP studies how tax audits affect firms AND aggregate output in Uganda.
Our collaborator Amanda Dos Santos (@_amandads_, amandadossantos.net) at Columbia Business School is on the job market this year with JMP "The Development of Domestic Bond Markets".
The overlap between academics who fretted over the danger of online echo chambers and academics who are leaving X for a platform where they can hear themselves louder is too large
I understand the academic impetus to move to a new platform. But I think it is bad for the commons if all the academics disappear and only talk to each other. We need your good ideas to be shared widely as much we ever did.
