We find, if anything, larger effects at lower pollution levels, in line with concave marginal damages.
Or, improved air quality might take longer than a session to improve behaviors.
We need more research on the mechanism behind pollution effects on productivity in the workplace. 4/4

Engagement/quality of interactions/politeness don't seem to improve despite evidence that PM affects aggression & stress in other contexts.
Why? 3/4

In the past couple of years we randomly put air purifiers at economics conferences to see if better indoor air quality improves engagement and interactions, which are key to knowledge transfer in our jobs.
Findings:
PM2.5 are halved within the first presentation! 🌬️
But... 2/4

We have a new CEPR Discussion Paper

Had a blast, as always. Wonderful meeting some of the old and new guard working on health and environmental econ topics. I learned so much from these thoughtful and kind scholars. And impeccable organization!

Milwaukee’s Lead Crisis: Flaky Paint, Closed Schools and a C.D.C. in Retreat Some children were exposed to lead and investigators found flaking paint inside aging schools. Two federal experts, expected to help guide the response, have lost their jobs.

Pardon my ignorance what is difference between factors and PCA?

Do you mean with principal component? We can. Not sure it's ideal.

Happy rejection day to all those who celebrate.
Here's to mean and careless reviews: may they come back and bite you where the sun don't shine.

All good things must end.
Thanks @mdgordo.bsky.social and all the great crowd @pse.bsky.social for hosting me and spoiling me for the past couple of months!

The way I understand this from summaries is that it allows to control for stuff but not to estimate the effect of stuff if that's also what you care about. But I'll read the actual paper.

Hey #EconSky:
Suppose i have a bunch of variables, quite correlated, describing public transit accessibility of nbds. I want to get the causal effect of public transit accessibility on Y. How bad is it if I LASSO, then OLS on selected vars?

Thank you so much for being there and sharing your insights. It was great to meet you!

Not on the horizon, but who knows :)

Hi, not public yet. let's chat in a couple of months!
How are you? Coming to aere?

Having a blast, getting great feedback and some snow!

Apply and join us in Rome!

They (so far) have guidance on their website.

Excited about this workshop!

Lead is in many homes & can poison people. There are steps people can take to reduce the risk of poisoning, e.g., during renovations. It seems that the UK government should provide guidance, at the very least copying theor cousins at US EPA.
I commented on this in an @financialtimes.com article.

Watching in shock. And signing.

Can't wait to visit, meet new people, and perhaps get some time on the slopes. I'm so rusty!

This will be fun!
Already enjoying top notch hospitality @pse.bsky.social from @mdgordo.bsky.social for my sabbatical.

Sometimes it's reviewer 3, not 2.

Every bit of this thread is 🔥, but this bit resonates especially.
When I failed my first mkt I couldn't understand how ppl could say "everything will be ok".
It turned out to be more than ok, after the grief, in part because I allowed myself to embrace unforeseen opportunities. No one size fits all.
