https://twitter.com/foster_type/status/1857224392662515789The National Bureau of Economic Research has good norms about avoiding directly prescriptive language. Your paper can analyze single-payer healthcare and report costs and benefits given the model you wrote down without then saying, "And therefore we should do this!"
https://twitter.com/eigenrobot/status/1849201670280167731I pick on this thread to illustrate how misleading these critiques can be -- they are often as ideologically motivated as the papers they critique.
https://twitter.com/itaisher/status/1839341047123755471There are huge and policy-relevant questions now or in the near-future (e.g. SB 1047). The world is not going to wait on our toolkit to catch up. We need to do the best we can with the tools we have available, and develop new ones appropriate to the urgency of the question.
https://twitter.com/ben_golub/status/1838415119186862430The kind of work by applied economists that I expect will *publish well* over the next 5 or so years are studies that say things like, "We study the introduction of the PC/electricity/cars/agriculture/etc... and use this to learn about skill-biased technological change."

How many other groundbreaking results for abandoned projects are gated within pharma companies and never see the light of day?
https://twitter.com/Afinetheorem/status/1815413103221407772Some UBI proponents say: a UBI will fix market failures. People who don't have access to credit will start businesses. People afraid to seek medical care will get needed care, improving health. The (excellent) study above finds little evidence for these.

https://twitter.com/DAcemogluMIT/status/1659593970580701190Intelligence is not binary. Humans are very good at say 10,000 cognitive tasks (the specific number is made up). GPT-4 is very good at 50, and superhuman at a handful. Subsequent models will be more capable at a broader range of tasks.

https://twitter.com/ChadJonesEcon/status/1651219721205977088I especially like that @ChadJonesEcon considers the value of potential mortality reductions from AI, which seems essential and overlooked in this debate, and that now needs to be integrated with the considerations above.
https://twitter.com/danascoot/status/1651406474889900034A cardinal and understandable mistake that grad students make is to think: "I have been working on X project for 2 years and it is my first project. If I don't have a paper, I have accomplished nothing. So, I'll keep trying to write a paper I know should not be written."
https://twitter.com/mjs_DC/status/1641438679460872192We know that cost-sharing leads people to indiscriminately cut back on care. They don't just cut back marginal stuff -- they also do less of valuable stuff. We saw this in the RAND experiment (below):
https://twitter.com/Jabaluck/status/1639666515396968452The value of rewarding innovations likely to make AI safer seems very high to me given recent developments (although I completely agree with everyone who emphasizes *uncertainty* both about AGI timelines and consequences).
