Tim Harford gives his Top Ten economists on Twitter. The one most known to this readership is @dambisamoyo. Then Tim adds another category:
Honourable mentions – a subjective combination of econ tweeters who are popular, interesting or under-appreciated
I will overlook Tim’s blatant self-promotion of including @TimHarford on this list, in return for blatantly noting that he also includes @bill_easterly.
