@vectornomist writes that "Just repeating 'all models are wrong' is not enough anymore."

I think he refers primarily to econometric models. As an applied theorist, I think that being "wrong" is part of the definition of a model. And D Cox's rule that "all models are wrong, some are useful" has always been and will always be right.

I like reading #introduction posts even from those I know, so here's mine:

I'm a researcher at the French CNRS. I study the applied practices of economists in the past 70 years or so, across fields (macro, urban, public, welfare etc), topics, methods & policy advice

I think that it is very important for economists & public at large to understand the history of their concepts, tools & models, so I try to post relevant research, archival nuggets & thread some stories

reasons mastodon's "viral dampening effect" is a good thing:

👉🏻 no "main character of the day"
👉🏻 no free text searching for people to get angry at (and harrass)
👉🏻 doomscrolling is *actually bad for you* and not a thing we should be trying to replicate
👉🏻 birdsite's virality is heavily driven by actual paid advertising and bots. You think that "Explore" tab gets its content organically? really? That's not making connections between people, it's about driving sales.

Mastodon is not, and should not be, a 1:1 replacement for Twitter. But it *can* be a new place for you to make valuable connections with other human beings. #twitter #twittermigration

The Musk-induced Twitter-Mastodon exodus provides an interesting research opportunity. The basic RQ is understanding the nature and size of network effects. An additional RQ is the effect of multi-homing, in particular users (like myself) who have recourse to a cross-posting app. Is multi-homing favorable or unfavorable in terms of a Twitter-Mastodon equilibrium switch? Not obvious to me.
I've donated to Wikipedia several times in the past. I have not responded to Wales' latest email appeal, partly because of reports that only a small fraction of the funds are actually used to maintain Wikipedia. Honestly, I cannot recall the details. What do people think about this?
A few months ago, I made a futile attempt to switch from WhatsApp to Signal. The latter is superior to the former in all dimensions except network size. I tried to convince many of my friends and family to switch. I failed, and by now I've given up. I don't like WhatsApp's parent company but may need to live with it.
What is (or should be) the equivalent of #EconTwitter on Mastodon? I understand hashtags are particularly important here.

Every year, the US government conducts a remarkable experiment in immigration policy:

It uses a randomized lottery to allocate, at a key step of the application process, the principal US work visa for low-skill jobs.

Ethan Lewis and I study winners and losers of this lottery to estimate the effects of hiring immigrants for basic work on US firms and workers.

The Effect of Low-Skill Immigration Restrictions on US Firms and Workers: Evidence from a Randomized Lottery

Founded in 1920, the NBER is a private, non-profit, non-partisan organization dedicated to conducting economic research and to disseminating research findings among academics, public policy makers, and business professionals.

Unlike Twitter, when you 'like' (Favourite) something here, it doesn't share that interaction with your followers.

If you've found a post or a piece of art that you've enjoyed - boost that toot! 

#introductions I'm a Portuguese economist at New York University's Stern School of Business. Like others, I am trying out Mastodon as an alternative to Twitter.
