The Value of Information in Efficient Risk-Sharing Arrangements
Suppose that agents share risks in competitive markets. We show that better information makes everyone worse off if the economy has a representative agent--that is, the economy's demand for state-contingent consumption equals the demand of a hypothetical agent who owns all the economy's wealth. The representative agent, moreover, is normatively unrepresentative: although each agent dislikes information, the "representative" agent is indifferent. Although we emphasize pure exchange, our results imply that a representative-agent model might seriously misstate the welfare effects of improved information in an economy with production and risk sharing, even if it performs well otherwise.
