We study a model where a large number of citizens learn a hidden state individually on an online platform. The platform receives news reports about the state and imperfectly filters misinformation in the reports, triggering conflicts about the value of the state among the citizens. We show that a...

We propose a simple test for moment inequalities that has exact size in normal models with known variance and has uniformly asymptotically exact size under asymptotic normality. The test compares the quasi-likelihood ratio statistic to a chi-squared critical value, where the degree of freedom is...
