This paper develops a general equilibrium model to examine the role of information technology when intermediaries facilitate the origination and distribution of assets given information asymmetry. Information technology measures the informativeness of asset-quality signals received by intermediaries, who purchase assets produced
by originators and then resell them to uninformed investors. Allowing intermediaries to operate has a mixed social welfare effect: Uninformed intermediation can be welfare reducing when adverse selection is severe in the economy, while informed intermediation always improves social welfare.
