My colleagues at Cornell simulated various tariff and retaliation scenarios proposed by Trump on China, Canada, Mexico, and the rest of the world, analyzing impacts on trade flows, sectoral output, real GDP, etc.

I haven’t carefully read what their estimation strategy is, but they do multiple hypothesis correction, there seems to be a plausible biological mechanism and there is also a list of conditions with increased risks (mainly GI related), so I am less skeptical, but haven’t done careful due dilligence

Somewhat relatedly, GLP-1s are having positive “side effects” as a function of treating obesity on some mental health disorders. Also VA sample in Nature Medicine

Lots of people think Pretty Woman is an unrealistic depiction of the American dream and I'm afraid I must agree.

Pepsi facing an FTC lawsuit shows the impact of big-box retailers like Walmart shaping supplier contracts. My colleague’s @hristakeva.bsky.social research shows that smaller retailers, without this leverage use product selection and supplier replacement threats as tools to negotiate terms.

Our paper develops a new approach for estimating demand nonparametrically while imposing economic constraints and comes with a new package, NPDemand.jl! Some things we do in the paper 1/

Once we acknowledge it, we can make progress toward understanding the role of context, endogenous responses, etc.

One of my favorite papers to provide clarity of though in this way is this one....

Can we request them as a reviewer? 😆

Feeling a bit surreal—just heard that JP Morgan and Morgan Stanley issued equity research notes on our paper with
@hristakeva.bsky.social and @leofeler.com

This is probably the closest my research will ever come to influencing markets! 📉📈

Do I know any researchers who have done research on biomarker data in the HRS survey, ideally blood-based biomarkers, e.g. of ageing?

If so, very curious about sample size issues, particularly in case of running similar analyses in smaller countries.

Was thrilled to learn that @larsvil.bsky.social has a tutorial on reproducibility! Check it out, #EconSky.

🚨Closing out 2024 with a new paper with @hristakeva.bsky.social and @leofeler.com: How GLP-1 medications like Ozempic are reshaping food demand and changing the rules of the game for the food industry.

Here are the first five sets of slides:

01 Introduction: psantanna.com/DiD/01_Intro...

02 Classical 2x2 setup: psantanna.com/DiD/02_two_b...

03 Clustering issues: psantanna.com/DiD/03_Clust...

04 Functional form: psantanna.com/DiD/04_Funct...

05 Covariates: psantanna.com/DiD/05_Covar...

While this has happened many times before with automation and productivity gains, it makes me think about the shape of the marginal rate of substitution between labor and leisure—as getting more leisure gets cheaper, we might not actually want all of it, even at the price of zero.

Su šventėmis!! ❤️🇱🇹

Ah, that must be the Clausian Limit Theorem

that addresses only the 1:1 problem and isn’t easily scalable to 1:M—the true source of stress and deadweight loss. :)

That's meta. Or should I say... you really stitched that together!

When it comes to Russia, always listen to the Baltics (and Poles)…

Whoa, missed this paper when it originally came out last year.

This paper studied 117 salespeople, linking DNA with key performance metrics like revenue, opportunity recognition, and effort.

The result? Evidence of a "Sales Gene"!

Way to go and that is a very good and well done paper!

Thank you! Yes, we would like to investigate how the treatment effect varies with, e.g, income or interacted with a continuous variable. Trying to see if there is a more efficient way to estimate this in pooled data without subsetting, as the overall sample is not very large.

Thank you! Will check for cohort treatment effect heterogeneity, as TWFE does indeed allow for more flexibility. Another option is to use the Callaway and Sant’Anna estimator on subsamples, but quickly losing power since the sample is not very big.

What's the latest on correctly implementing staggered diff-in-diff with interaction effects, such as treatment effects interacted with income groups? Asking for a friend...
NOT.
