IMO, one of the most time-saving use cases of LLMs is handling the syntax of a new library, which can be time-consuming to learn if it's only needed, say, once. They can also help save time when finding bugs in code, especially when the bugs are common.

A few comments on the @mark-carney.bsky.social platform released today. You can find it here: liberal.ca/cstrong/.

I provided some 'sounding board' advice here and there to those working on the platform. As always: I disclose, but you can decide what weight to put on that.

Understanding causality vs. correlation is genuinely hard especially on complex topics like inflation. Our research finds that 60% of Americans think high interest rates cause high inflation & support rate cuts to fight it. But high rates usually respond to inflation,not cause it

Reverse engineering worries me. I love good data work, and I love applied theory - but trying to reverse-engineer a model from stylized facts is ill-posed. Which explanation to use? My sense is that insisting on data+theory+quantiative application has been a detrimental to publishing in econ

One concern is that much of the economics is learned by tinkering with simplifications/FOCs/edge-cases. These tools might make it easy to write down models, solve them numerically/symbolically/etc., but ultimately provide papers with fewer insights. At least for applied-theory papers.

Glad we got through the tariff emergency (at least the first wave of it....).

Also glad that people are bringing creativity, energy, and determination to figuring out a medium and long-run response.

But I want to throw cold water on three ideas I've seen floated. I'll explain...

UW–Madison economics professor Kim Ruhl appointed as member of President’s Council of Economic Advisers Established by Congress in 1946, the CEA comprises three economists who advise the U.S. president on a wide range of economic policy issues based on data, research and evidence.

Prof. Kim Ruhl (UMN PhD 2004) of University of Wisconsin-Madison has been named as one of 3 members of President Trump's Council of Economic Advisors. I admire Kim for his service to our country, and I hope he is able to have a favorable influence on US economic policy.

Economists need to consider bold new ideas and perspectives which don't fit into existing research templates. If we never pull the multiarmed bandit on crazy ideas, then we can't escape local optima.

The way to make that happen is for journals to publish clean, simple, and new perspectives.

Economists often need to solve the same model an enormous number of times during estimation/calibration - otherwise I know nothing here on the details. But the idea is kept clean, and thanksfully the referees/editors let it stay focused.

I have an AI generated proof of a statistics lemma beyond my measure theory paygrade. Question: how many samples from LLMs do I need in practice to be 95% confident the proof is correct? Do different LLMs help ensure that there is no correlation between these draws?

Location: Zoom Link https://bowdoin.zoom.us/j/96039587180

Who: Anyone. Grad students, researchers, government workers. Private sector is okay but in that case if your question requires work that exceeds the allotted time I may request to negotiate a consulting fee.

What I can probably help with: Theory questions. Research design. Modeling.

Particular expertise: Time series. Causal inference. Bayes. Structural approaches. Machine learning.

Theory: Asymptotics. Statistical learning. Bayes/MCMC. Identification. Decision theory. Semiparametrics.

Fields: I know most about macro (DSGE, heterogeneous agents, VARs, etc), but can follow along in applied micro (labor, development, health, etc) & some finance.

Code: I think in R, can write Julia, and can get by in Python. I am likely to suggest you build a model in Stan. I know Stata but if it’s relevant to your question I suspect you can get better help elsewhere.
