Abstract
We characterize environments having a representative agent: an agent whose preferences over aggregate alternatives correspond to a weighted average of the population’s utilities for the disaggregated alternatives. The existence of a representative agent imposes strong restrictions on individual utility functions — requiring them to be linear in the allocation and additively separable in any parameter that characterizes agents’ preferences (e.g.; a risk aversion parameter; a discount factor; etc.).
