Reading this at the moment, online... so far, pretty interesting collection of idea papers and analysis! It's all about post-Keynesian economics, which I have some doubts about, but I think it's important in understanding both how Keynes is still relevant today (if not more relevant in some ways), and how we need to move beyond Keynes (not by tossing his contribution away, but by expanding upon it in totally new ways). Keynes ideas worked in closed societies, with clearly delineated borders. In our global society, we have to focus on lifting all boats, not just ours.
