A cool new project of mine: how to keep up with new literature on innovation, entrepreneurship, and econ of AI? These areas are very interdisciplinary, and working papers play a huge role. Subscribing to dozens of weekly journal emails makes no sense. Let's fix this with AI. 1/x

[Josh Feng @joshfeng89]

Our work complements existing findings in the literature, and there's quite a bit more to do in terms of connecting changes in the IP system to downstream markets (consumers, workers).

Here's a link to the article (ungated for 50 days): https://t.co/dleBN0ZZYO

Alice v. CLS Bank (2014) was a major Supreme Court patent decision that increased the stringency for business method and software patents. What was the impact of this decision on innovation?

[Josh Feng @joshfeng89]

There has been constant Congressional debate over legislation to overturn Alice and other related Supreme Court patent decisions. Our work suggests that overturning Alice may lead to an increase in marginal patents, which might be especially relevant in the current AI boom.

And an older video on when to pull the goalie in hockey games (and the more general idea of aggression coefficients). I have no doubt the Olympic hockey coaches will all pull their goalies too late.

Many industries where the government is a major regulator, purchaser, or supplier suffer from severe worker shortages (e.g., healthcare, transportation, education, public safety).

A quick thread on our new @restatjournal showing how government payment incentives can help:

Great to see our oped on AI and jobs out in @ProSyn, with Philippe Aghion and Simon Bunel.

While many warn that AI will undermine employment and offer only modest productivity gains, empirical studies continue to suggest otherwise👇👇👇
