Since this is one of my favourite photographs from that trip, I was oddly pleased when I got my review copy of Charles Manski's new book, Public Policy in an Uncertain World, to see the front cover:
I like to think there is some symbolism to this since I have learned a lot from Manski's work.
Note: You can read the review of the book I wrote, targeted mostly at a South African public policy audience, here. There are some open access copies here (until they run out). For academic economists the review by Guido Imbens, and response from Manski, in the Economic Journal is particularly informative.
