Here’s the monthly data with a 12-month trailing average, so we don’t “look ahead” of the time series. We can see that visits from Canada are substantially down. Like, a *lot*. And if we looked at the French series by itself we’d see something too. But it’s not on the scale of Covid. Yet.
Smoothed monthly graph shows Canada has dropped in visits substantially, but not to the extent we saw in Covid

This admin has spent years going after science. It proposed the largest cut in NASA’s history, about a quarter of the agency and half of its science programs. But last month, a groundbreaking telescope left the launch pad anyway. And the story of how it got there is our good news this Sunday.

I'm surprised a community of publishing writers can blame AI for the problems of peer review when those same writers cite our study, "the strain on scientific publishing", which characterizes how this problem existed before AI. bit.ly/StrainQSS It's the incentives structure, not the AI. 1/n

🚨Elsevier forces out Games and Economic Behavior (GEB) Editor, entire editorial board has resigned, current board only handling new submissions until Nov. 14 #econsky
    Dear Advisory Editor of GEB
    We are very sorry to be the bearers of bad news for GEB.
I learned from Elsevier on Wednesday July 28 that, contrary to my expressed willingness to continue, my 3-year contract will not be renewed.
    "Moving towards a closer alignment with Elsevier strategic priorities and publishing policies" was offered as the motive for this decision. Requests for explanations, first by me, then in a collective letter by the other six Editors, were dismissed by Elsevier which simply reaffirmed its legal power to make such decisions.
    Elsevier then started precipitously its own search for new Editors without input of the Editorial Board.
    By Friday August 14 all seven Editors have sent their resignation, requiring a 3-month advance notice.
    Therefore, we will continue to manage as before the papers currently under review and the new submissions until Saturday November 14. After this date we will only complete the evaluation of papers still waiting an editorial decision.

New paper from me and @jaredb-econ.bsky.social on the debt and our fiscal outlook! Before we dig into the paper, I think we should be frank about how we got here. At the beginning of the century, debt was on track to be stable indefinitely. Then Congress enacted enormous tax cuts. Now it's not.
