Climate Extrapolation and Relative Asset Pricing: Evidence from Bordeaux Premier Cru Wine Auctions This paper offers evidence for climate extrapolation, a behavioral tendency where economic agents project salient local climate risks onto an asset's valuation.

Happy to present my newest paper on climate finance and wine economics. TLDR: I show evidence of "climate extrapolation": Investors focus on their local climate experiences when valuing an asset, even if that asset is tied to a different geography.

What's in it for them, you think? Because this seems like true BS.

Can't read it, but sounds interesting. Congrats. When did you do this? How do you ask for priors and credibility of the signal? (How sure are you that this is the only information they saw?) Did they update beliefs or were they always going to vote that party? (Do you see differences in gender?)

Thrilled to share that my article "Railroad Bailouts in the Great Depression" (co-authored with Lyndon Moore) has been conditionally accepted by the Journal of Economic History!

I like Claude better in that regard. ChatGPT has improved when it comes to coding.

Some episodes of Breaking Bad and Better Call Saul would like to have a word with you.

For what's it's worth, I wrote about your paper for the (Dutch) investment magazine Investment Officer. I think it's very important, also for institutional investors.

And a nice guy too. I still remember the lunch I had with him a couple of years ago after a seminar in the Netherlands.
