EDIRC, the directory of economics institutions, has over 15K records, and quite a few suffer from link rot. Any help getting those corrected is appreciated.

Maybe this is why the prices increase. Smaller supply of houses.

With this change a few weeks ago, the impact of AI bots on server activity has been severely curtailed. I am thus making these changes permanent. The drawback of the loss of some services for human users of IDEAS is unfortunately worth it.

The H in JHR doesn't stand for History?

TBH, journals are a historical record of where the research frontier was.

OK, but think of all those who are forced to live together due to lack of housing. They would be happier on their own (or smaller hoseholds).

I suppose household size is also getting smaller, compounding the issue, right? Of course, household size is also dependent on housing availability, which means that the problem is even bigger.

Air traffic controllers earn a median salary of $137,380 annually. The top 25% of controllers earn $176,720 or more, while the bottom 25% earn $96,870 or less. In St. Louis, MO, the average salary for an air traffic controller is around $73,623 per year, according to Indeed.

In light for recent air traffic incidents, I am not exactly reassured about flying from St. Louis. #Stl

Universal Basic Income versus Unemployment Insurance In this paper we compare the welfare effects of unemployment insurance (UI) with an universal basic income (UBI) system in an economy with idiosyncratic shocks to employment. Both policies provide a s

I feature often IDEAS because I manage it, but of course another really good RePEc service is EconPapers that has many of the same features. Use the one you prefer to access the same data.

RePEc attempts to categorize registered authors by field, based on in which NEP report their working papers where disseminated. Certainly not a perfect scheme, but it is a start.

Totally possible, I just wonder about critical mass for many states... so maybe regions. I will look into it.

Looking for economists to follow on BlueSky, in particular in your field or geographic area? IDEAS has various lists to help you. See there as well to get listed (hint: just add your BlueSky handle in your author profile)

FY 2026 R&D Appropriations: House R&D Report | American Association for the Advancement of Science (AAAS)

With the House potentially starting their recess early, here's a report on what they've proposed so far for FY 2026 Appropriations.

I would have expected left and right monitors to have diff, and middle one diff-in-diff.

If you add a link to an abstract page on IDEAS to a BlueSky post, an abstract will be added as an image to your post. There is also a Bluesky logo on each IDEAS page to make it even easier.
