Sen’s Paretian Liberal Paradox

I was absolutely tickled to find a discussion on Brad DeLong’s site and Robert Waldman’s site about Sen’s seminal article on the impossibility of a Paretian liberal (that’s small-l classical liberal). Takes me back to my undergraduate days, when I had a superb economics honors seminar with the irrepresible and ever-stimulating Dennis Sullivan, one of the primary people who encouraged me to go to graduate school in economics.
