A colleague of mine at American University has been sharing some material by Duncan Kennedy, a former professor of his at Harvard Law School, who he describes as a left-leaning law and economics scholar. Anyone that knows this field knows that that can be rare - it's dominated by more conservative thinkers.
The first article, which he enjoyed a lot, is about Veblen's fetishism of commodities. The second one, which actually looks more interesting to me, is about weighing values other than efficiency in legal decisions utilizing cost-benefit analysis (of course there are ways to do this using the tools of cost-benefit analysis too). This is a longer bibliography.
