My colleague and (I hope still) friend, Chico Ferreira recently took the trouble to write a comment on my earlier LTD post on measuring inequality of opportunity in the context of human development. Early on in his comment, Chico also paid me the compliment of a being a “clever guy”, which was nice until I read on and found that while he agreed with some of what I said there was a lot he didn’t like. Now Chico is a really clever guy, and this is an area he knows a lot about. So I realize I’m treading on thin ice when I say I’m not completely convinced about his ripostes. But let me take the risk. Chico’s not just super-clever – he’s also very nice. So if the ice cracks and I fall in, I think there’s a good chance he’ll pull me out.
