Research Abstract

I have investigated the following three theoretical aspects of intertemporal resource allocations : (1) a characterization of optimal paths for economic growth ; (2) representation of intertemporal preferences by utility functions ; (3) solutions to fair division problems. I have proved the existence of optimal path for economies with increasing returns in which a representative agent possesses a recursive utility function that endogenizes time preference for consumption paths. In the fair division problem, I have demonstrated the existence of solutions which satisfy both efficiency and fairness.
