Fear of a crash drives some investors to “step out” of the market. Stocks sensitive to this variation had lower returns. Even “non-marginal investors” matter to market prices, from @WGoetzmann, Dasol Kim, and @RobertJShiller nber.org/papers/w35708

Wow, incredible! Mokyr is awesome - he’s the father of the “ideas school” of the Industrial Revolution, which is one of the inspirations for Works in Progress, and the author of the best book I’ve read on the Irish Famine. So exciting.
BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2025 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel to Joel Mokyr, Philippe Aghion and Peter Howitt “for having explained innovation-driven economic growth” with one half to Mokyr “for having identified the prerequisites for sustained growth through technological progress” and the other half jointly to Aghion and Howitt “for the theory of sustained growth through creative destruction.” #NobelPrize

Today, I went to our Social Security Office to conduct Oversight and was denied access to meet with officials. Instead, we were given a generic phone number in another state and denied entry past the waiting room. Here’s what we found out ⬇️

Cecile Richards dedicated her life to protecting and expanding women’s rights. She never wavered in her commitment to ensuring that women had access to the reproductive health care they needed, and her leadership at Planned Parenthood led to the inclusion of important healthcare provisions in the Affordable Care Act. Women of all ages knew they could count on Cecile, and Michelle and I will always be grateful for her advocacy. We send all our love to Kirk, Lily, Hannah, Daniel, and all those who loved and admired her.

We find that an increase in stock market wealth increases entrepreneurship and induces entrepreneurs to start larger and more profitable firms ⬇️ Great to work on this with @ptnenov @gchodorowreich @VitorPe94384701
(1/n) New paper! “Stock market wealth and entrepreneurship” by @gchodorowreich, @ptnenov, @VitorPe94384701, @alpsimsek_econ. Higher stock market wealth, driven by idiosyncratic variation in returns, increases entrepreneurship and firm profits by relaxing financial constraints.
