The Non-Existence of Representative Agents
@article{Jackson2015TheNO, title={The Non-Existence of Representative Agents}, author={Matthew O. Jackson and Leeat Yariv}, journal={Macroeconomics: Aggregative Models eJournal}, year={2015} }
We characterize environments in which there exists a representative agent: an agent who inherits the structure of preferences of the population that she represents. The existence of such 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.). Commonly used classes of utility…

This result demonstrates a fundamental difference between a representative agent and truly heterogeneous quantal responders and suggests that when fitting quantal response specifications to aggregate data from a population of subjects, the noise terms should be allowed to be jointly dependent across actions.
