This paper studies when equilibrium prices can aggregate information in a large market. We consider an auction trading mechanism, where a large population of buyers and sellers receive
private signals about the common value of an asset. Our main result identifies a property of information—the betweenness property— that is both necessary and sufficient for aggregation. The characterization allows us to make predictions about equilibrium prices in complex information environments. As an application, we consider a multidimensional environment where the value of the asset depends on multiple inputs but signals are input specific. Information in the market is highly fragmented, yet equilibrium prices can aggregate information generically.
