The BBC radio program Business Daily had a good segment on the future of economics, with good discussions of Keynesianism and behavioral economics (though not quite enough on heterodox approaches). The main off note (to my mind) was the bit with Michael Sandel, with his emphasis on the "normative" foundations of economics. I don't think economics needs to rediscover its ethical foundations (in Adam Smith) as much as it's political foundations (in Marx). But otherwise I thought this was worth a listen.
