We study when equilibrium prices can aggregate information in an auction market with a large population of traders. Our main result identifies a property of information---the betweenness property---that is both necessary and sufficient for information aggregation. The characterization provides...

We study the effects of unexpected changes in the stance of monetary policy on mutual fund performance and allocation decisions over the recent period of unconventional U.S. monetary policy. Taking an agnostic approach on the transmission mechanism of monetary policy on mutual fund investing, we...

We study the links between unexpected changes in the stance of monetary policy and mutual fund performance and flows using data over the 2000–17 period. We find that monetary policy shocks, through their direct effect on asset prices, can have an impact on mutual fund returns and flow...

Many policy reforms involve gains for some voters at a cost borne by others, and voters may be asymmetrically informed about who gains and loses. This paper shows that the interaction of distributive politics and asymmetric information generates an adverse selection effect: when an uninformed...

We study the problem of aggregating private information in elections with two or more alternatives. We characterize environments where information can be aggregated asymptotically by a sequence of equilibria of voting games as the electorate grows large and explore the implications for the...

Siga and Mihm (2020) characterize the information environments where prices can aggregate information in a competitive auction market with an atomless population of traders. In this paper, we provide an explicit model of the large population where implications of the law of large numbers for...

It is well-known that stochastic dominance is equivalent to a unanimity property for monotone expected utilities. For lotteries over a finite set of prizes, we establish an analogous relationship between likelihood-ratio dominance and monotone betweenness preferences, which are an important...
