Although competition law deals with economic matters, such as market power or firm behaviour (prices, mergers, etc.), competition law has long been a territory for lawyers. However, over the last ten to fifteen years, economists have played an increasing role to advise both undertakings and...

We study a hybrid marketplace such as Amazon selling its own products and set- ting a commission rate on revenues of sellers engaged in monopolistic competition with free entry. For a large class of microfoundations based on a representative agent, the introduction of products by the marketplace is...

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 introduce a discrete-time search game, in which two players compete to find an invisible object first. The object moves according to a time-varying Markov chain on finitely many states. The players are active in turns. At each period, the active player chooses a state. If the object is there...

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...
