@timalthoff @Nature Love this! I have always wanted to write a paper like this. How does one get access to data like yours?

I’m excited to share our new @Nature paper 📝, which provides strong evidence that the walkability of our built environment matters a great deal to our physical activity and health. Details in thread.🧵 nature.com/articles/s4158…

Yesterday I attended the session "Publishing in #Economics" at the #NEUDC2024 with @MelissaLDell (JPE) @afosterri (JDE) @SuriTavneet (REStat) and Laura Schechter (JEBO) and I think everyone should benefit from the amazing insights and advice we received, here is my summary! 1/n

I look forward to presenting at the Economics of Violence Against Women Workshop organized by Sonia Bhalotra at @uniofwarwick next week! Fantastic speakers and exciting research on all aspects of violence against women. #EconTwitter

🚨New Working Paper🚨 "Free Public Transport: More Jobs without Environmental Damage?" by Rodrigues (br.linkedin.com/in/mateus-rodr…), @DaMataDan and Possebom Paper: arxiv.org/abs/2410.06037

If you are taking (or teaching!) a course on statistical inference/regression, I have a draft textbook available for free mattblackwell.github.io/gov2002-book/ Recently updated to introduce design- and modeled-based inference. Emphasis on intuition and rigor.

Leaf blowers should be either banned or severely taxed and the proceeds go to the immediate neighbors and those who walk their dogs and children near the offenders' property.

I am very happy to see this out! 🎉 Check also the R programmes and replication files on Github (shorturl.at/hO24S) or at the @RevEconStudies. For a thread on this paper, check out my earlier post (linked below)! 1/2

@MattCowgill I feel like a this is the right spot for a "some men would rather ... Than go to therapy" joke, but I am afraid we are not close enough. Alas

someone out there should make the pre-1978 Australian labour force survey data nice and tidy and easy to load in R

@SergeyVAlexeev @economeager Just head to r/Australia on Reddit to learn that it is about a mix of concerns related housing prices, quality of domestic higher education, and immigration---none of which are effectively tackled by this policy.

Could you help me understand the reasoning behind the limits mentioned in the article? It mentions fairness, so I'm curious about the criteria being used. Is this related to the housing market, or is it about managing labour market needs? I just want to get a better grasp of the situation. Thanks!

unbelievably fucking stupid nonsense australia

Sharing a new working paper with Anqi Zhao & Peng Ding @pengding00, titled "Factorial Difference-in-Differences." arxiv.org/pdf/2407.11937… 🧵 Comments and suggestions are welcome!

@economeager Fuck.

@Apoorva__Lal @s3alfisc I'll have a look---thanks!

@FabItMart @s3alfisc Confint method rlasso in hdm cran.r-project.org/web/packages/h… although there isn't anything inherently lasso-y about this

spiel on simultaneous confidence intervals for event studies (now in pyfixest #pointwise-vs-simultaneous-inference-in-event-studies" target="_blank" rel="nofollow noopener">py-econometrics.github.io/pyfixest/diffe…); implemented solely via confint() first, now in the plot method h/t @s3alfisc. why aren't these used more widely? is it as simple as (1) confints are wider (2) software?

We worked with the government of Rio de Janeiro to test the impact of publicly provided daycare. nber.org/papers/w30653 Among the most sustained impacts, seven years later? Children were taller: care with nutrition in the early years really matters.

@kylefbutts @grant_mcdermott It seems like the solution today happens to be simple (see Pedro's reply). Thankfully this is a headache for another day 🙏 Thanks a lot for helping, it's good to see Econometrics Twitter is still alive and kicking!

@FabItMart @grant_mcdermott That would suggest very weakly identified coefficients. Are you block bootstrapping by units? Coefficients on treatment dummies?

Shot in the dark in these Late #EconTwitter Age. I'm trying to take the difference between two event studies coeffs estimated via feols() with sunab(). (Triple Dyn DiD). Struggling to get valid SEs both via bootstrap and delta method. Tips? @kylefbutts @grant_mcdermott #rstats
