Of all the albums from my youth, Siren Song of the Counter-Culture will always hold a special place for me. No idea whether it is the reminiscence of high school days or just the raw sound Rise Against lost over the years. Just a great 40 minutes of music.

Academia really is glorious business. I just spend about an hour collecting all 32 variables in the SCF that are necessary to calculate real estate wealth of respondents. Riveting.

Ich wollte die Brände in Kalifornien zum Anlass nehmen etwas über Klimawandel, Naturkatastrophen und Versicherung zu schreiben. Dabei will ich auch etwas über die Lage in Deutschland sagen.

Ich denke, was die Klöckner Sache vor allem zeigt, ist eine gewisse Hilflosigkeit der Konservativen. "Wir machen doch alles was ihr wollt" impliziert, dass man mit realer Politik, Wünsche der AfD Wählerschaft bedienen kann. Ich denke nicht, dass das stimmt. Hass und Protest sind so nicht bedienbar.

Removing tail risk through tort reform increases the number of trauma units in hospitals and that reduces traffic fatalities in the affected HSAs. Fascinating presentation by Meghan Esson at the 2024 CEAR/ MRIC Behavioral Insurance Workshop.

Wanted to present a working paper here that @valuz, Ralf Elsas and I have been working on for a while now: ssrn.com/abstract=471.... This maybe a bit unusual for #Econsky as it not only has decision theory, but also some asset pricing in it. A thread:

Something worth pointing out about the plan to get rid of VA health care. It only saves money if you think that the vets shouldn't get services paid by gov't. If you want them to get services in another program, it'll likely cost more. The VA is very cheap.

I always read whatever Sam Bowles puts out. This with Mattia Fochesato. Humans have always competed for status and resources, but enduring inequality requires specific conditions: concentrated wealth, state power, and cultural acceptance of disparities. www.aeaweb.org/articles?id=...

Apparently some people need to hear this: the profit margin of the entire US health insurance industry is 3.3%. Many things are wrong in the healthcare system, but sometimes insurance companies are just the bearer of bad news.

As someone who has always (kind of intuitively) doubted that we should use weighted probabilities normatively, this is the aspect I enjoy most about this paper.

#EconSky Severe climate events (floods, wildfires) are raising insurance costs – on average, home insurance premiums increased 21% this year. Will policyholders keep insuring their homes? We (@blcollier2.bsky.social, @tobiashuber.bsky.social, Andreas Richter & I) explore this in a new working paper.

Just saw a defunct railway control center and looked it up. There is a website dedicated to information on these things. Super fun. Made me miss the olden days of the www when all we had were these little treasure chests maintained by enthusiasts.
