One of my recurring themes is the problematic nature of ownership in public companies. The shareholder-company relationship doesn't seem to function much like ownership (despite the best efforts of some of us) and at present I'm not sure the signs are good that it will in future (for example because of the DB to DC shift in pension provision, which will atomise share ownership further).
Both Duncan and Charlie are interested in this question too, so I'm passing the batton to you two to give your fellow bloggers a few ideas/comments on how we might make it work (or at least work better). What do we want pension funds, for example, to do? And pass this on to anyone else you think might have something interesting to say.
