As promised, here's a new post :) We’ve got 2 new DiD papers, 1 fantastic DiD guide, and a clever method from Athey–Chetty–Imbens on using experiments to fix observational bias Link: substacktools.com/sharex/3r81_DQS
UM making waves in Mexico!
I had the honor of presenting a keynote lecture at the @CEMLA Latin American Journal of Central Banking Conference in Mexico City last week. Thanks to the organizers for inviting me (especially Nelson Ramirez, who I taught at Wisconsin) & the presenters for a great conference.
I wrote a thing about "RL or control as Bayesian inference", which encompasses - RLHF and controlled generation in LLMs - Finetuning or guidance in diffusion models - Diffusion samplers from general unnormalized densities - Sequential Monte Carlo sampling for all of the above
How can we design algorithms that maximize social welfare, rather than profits? This paper merges multi-armed bandits and adversarial learning with optimal tax theory and welfare economics. @maxkasy @NicoloCB @Rcolomboni econometricsociety.org/publications/e…
I would not achieve this without the help of my advisor @Bellmanequation and all other faculties from the Econ department in @MiamiHerbert . I will attend the Midwest Macro Meeting 2025 to present our paper (with my advisor) as an incoming assistant professor in SIUE.
Congratulations to my first PhD student at @univmiami, @YangIvyXQ (center) on accepting a tenure-track position in Economics at @SIUE! We're shown here with the rest of our @MiamiHerbert Econ PhD group (watch for them in future) after a celebratory lunch in the department today.
Everything new is also old. This from my 1984 PhD thesis: "AI is an experimental science, yet the complexity of its programs and problem domains often makes the interpretation of results very difficult. Programs often contain so many components and parameters that limitations on…
For a GE analysis of the China shock, check out this paper by Lorenzo Caliendo, Fernando Parro, and Max Dvorkin 👇 CDP: 0.55 million US manufacturing jobs lost due to China shock (16% of the overall decline) Autor-Dorn-Hanson: 1.53 million
[Warning: this may offend some people!] I think economists have done society a disservice by elevating applied-micro studies that focus exclusively on the relative effects of trade across different groups of workers but are silent about the aggregate effects.…
From the Journal of Political Economy, this article investigates China's export growth to the United States from 1950 to 2008. Read "Trade Policy Dynamics: Evidence from 60 Years of US-China Trade" here: ow.ly/iWRp50VsRj9 @JPolEcon
I sent a message to my PhD students and postdocs at @Princeton a couple of weeks ago regarding freezes/cuts to federal research funding (this was before the freeze on federal funding to Princeton). I am sharing it here in case others find it helpful in having similar…

An important channel for macro uncertainty is the interplay of financial & labor markets. Uncertainty exerts downward pressure on asset values, discouraging vacancy posting and making it harder for workers to find jobs. Potentially inflationary. doi.org/10.1016/j.red.…

I will carefully read this paper. The key point that quantitative scholars ignore here is the cross-elasticity. If some part of Florida is not adapting to floods, then economic activity moves to another area that succeeds in adapting. This competition protects us. (1/2)

“Public financing under balanced budget rules” by @MinjieDeng and @changer_1 out now in @RevEconDyn show that that states with more stringent balanced budget rules exhibit significantly lower bond & CDS spreads, demonstrating the crucial role of default risk. (Link in next post)
Hosted a great fiscal & monetary policy conference at @MiamiHerbert, capped by Henry Lecture from @JohnHCochrane. (Click through for photos.) Thanks to all who spoke & attended. We hope to make it an annual event, so watch for a CFP and plan to join us in Miami next February.
Afternoon presenters: Nicolas Caramp, Bill Branch, Rodolfo Campos, Jarda Borovicka
