We conduct an experiment in which groups are tasked with evaluating the truth of a set of politically relevant facts and statements, and we investigate whether communication improves information aggregation and the accuracy of group decisions. Our findings suggest that the effect of...

This paper reviews recent research on the aggregation of heterogeneous time preferences. Main results are illustrated in simple Ramsey models with two or three agents who differ in their discount factors. We employ an intertemporal view on these models and argue that preferences of a decision...
