Recall that in the Solowmodel the saving rate is imposed, and there is no representation of preferences. The optimalgrowth model adds preferences for households, and derives an optimal saving rate. Utilityis maximized for the representative agent, given the technology that they re faced with. Thesocial planner s problem may be described as are summarized in the utility function:LES| c|'fc c4 Utility is assumed to be time-separable, that is, marginal utility of consumption today dependson today s consumption only.
