The modern Condorcet jury theorem states that under weak conditions, when voters have common interests, elections will aggregate information when the population is large, in any equilibrium. Here, we study the performance of large elections with population uncertainty. We find that the modern...

We consider a linear panel event-study design in which unobserved confounds may be related both to the outcome and to the policy variable of interest. We provide sufficient conditions to identify the causal effect of the policy by exploiting covariates related to the policy only through the...

Statistics can be used to reveal cheating and corruption. Statistics can see what cannot be perceived with the naked eye. This article discusses the disclosure of cheating by statistics seen in relation to similar studies. The evaluation process of a semester course at a university is a data...
