🚨🚨Hey undergrads and masters students interested in careers in applied econ research: My department is recruiting 5 full-time pre-doc RAs to start summer 2024! 🧵on why you should apply:
I am wondering if anyone have suggestions to speed up scipy.optimize.minimize in #Python? My demand estimation is taking too long (given the simplicity of it and I am giving it the exact analytical gradient, I am hoping for better.) Any thoughts?
We are hiring full time RAs at Wharton - especially relevant for undergrads and masters students interested in housing and household finance. Please feel free to circulate with interested students!

“New noncompetes banned for all workers as of effective date.” The FTC just issued a complete ban on all employee non-competes. No carveouts, no limitations, no exceptions. Wow!
If govt wants academics to do more practical work: (a) improve the quality and availability of data. Nobody can provide real-time analysis of data that are released with a 2-5 year lag. (b) increase social science funding at NSF to provide public goods not just QJE's. 1/4
As he says, academia’s very heavy emphasis on novelty incentivizes people to do the kind of work that’s not so useful to policymakers who mostly need to get the basics right — better data, a clearer sense of the overall state of the literature. slowboring.com/p/the-economic…
I applaud that editor. I believe there is a bias in editorial decisions in econ journals in favor of papers that “look hard” to produce. Degree of difficulty should be used to judge gymnastics and figure skating, not scientific contributions.
I recently shared an experience I had with a journal and was encouraged to share the decision letter more broadly. For the youngens who still get frustrated, this same paper was rejected by the QJE (a more appropriate "home" given the style.) It's always a lottery!

When I moved from econ to finance in '99, I gave up tenure. Didn't want my tenured job, but I got tenure back in a year. When I moved from finance back to econ in Aug., I gave up an endowed chair, because none were available in econ. But the regents just approved a new 1 for me.

Andreessen hits the nail on the head. To a first order approximation, AI will drastically improve the world for the better. AI will have unintended side effects, but society will deal with those as they come up. Regulating prematurely will lead to aggregate harm.
