I left academia for a variety of reasons, but one of them was the fact that more people read my shitty blog in about the first 3 weeks than would ever read any of my academic papers. And a related reason was that I thought the culture of the profession, at least in this country, worked against outspoken liberals. In my experience (this is anecdote, not survey), the majority of economists I knew were Democrats, if not especially liberal ones, but still they were generally more comfortable with economist public intellectuals who were right wing cranks than they were with left wing public intellectuals. Paul Krugman is shrill and whatnot.
Anyway, the point is... The Left needs more "respectable" economists who are willing to put themselves out there in public discourse space. You know, blogging, op-ed pieces, radio, teevee, etc. I was asked recently to list them and I didn't come up with many. Stand up and be heard!
