We had a discussion the other day of a paper, “The Economic Effects of Climate Change,” by economist Richard Tol. The paper came to my attention after I saw a notice from Adam Marcus that it was recently revised because of data errors. But after looking at the paper more carefully, I see a bunch […]
A whole fleet of gremlins: Looking more carefully at Richard Tol’s twice-corrected paper, “The Economic Effects of Climate Change”
I received the following email the other day (well, actually it was the other month, as we’re still on blog-delay): Dear Prof. Andrew Gelman, The ** Broadcasting Authority, together with ** – a well-established production company, are producing a documentary about Freud.

From 2006: Naseem Taleb‘s publisher sent me a copy of “Fooled by randomness: the hidden role of chance in life and the markets” to review.

I’ve been getting these sorts of emails every couple days lately: Respected Professor Gelman I am a senior undergraduate at Indian Institute of Technology Kanpur (IIT Kanpur).

From 2011: Chapter 1 On Sunday we were over on 125 St so I stopped by the Jamaican beef patties place but they were closed. Jesus Taco was next door so I went there instead. What a mistake! I don’t know what Masanao and Yu-Sung could’ve been thinking. Anyway, then I had Jamaican beef patties […]
