Partho, Thanks for the ideas and the attached resources are very enlightening. Yes, it's an Inter-temporal utility maximizing problem, and now it looks to be far-fetched for me! Nick, I appreciate your thoughts too. I hope someone comes up with something in this field in the very near future! thanks guys!
