I confess I have done no more than skim this paper by Maxim Pinkovskiy of the Massachusetts Institute of Technology and Xavier Sala”i”Martin of Columbia University and NBER. I will have a go at reading it properly later. I got the link from Tim Worstall, who gets distracted from “ragging on Ritchie” into a rather moving defence of his belief that capitalism is the system that actually works when it comes to lifting hundreds of millions of people out of poverty.
I liked the title. I liked it so much I think I will type it out again.
