We study the effect of Amazon's dual role, as a marketplace and retailer, on product recommendations. We find that products sold by Amazon receive substantially more ``Frequently Bought Together” recommendations across product categories and popularity deciles. To establish causality, we exploit...

Actively choosing to learn tends to involve market failure: if the new knowledge is not shared with everyone else, learning produces asymmetric information; if the new knowledge is welfare relevant and shared with everyone, learning essentially amounts to private provision of a public good,...

Deforestation in the Brazilian Amazon has fallen sharply since the early 2000s. Better enforcement of environmental law is believed to play a major role in this success story, and the literature provides support to this theory. Deforestation is one of the greatest culprits of carbon emissions in...

In the talk we will discuss Poisson reduced rank models for low-dimensional summaries of high-dimensional Poisson vectors that allow for inference on the location of individuals in a low-dimensional space. We show that under weak dependence assumptions, the locations can be consistently estimated...

In this talk, I will introduce a new multilevel-Langevin method dedicated to the Gibbs sampling. More precisely, this procedure both inspired by [Szpruch et al., 2016] et [Pagès-Panloup, 2018] is based on a multilevel combination of pathwise averages of discretized schemes of overdamped-Langevin...

We estimate the likelihood of miscarriages of justice by reframing the problem in the context of misclassified binary choice models. Our estimator is based on new nonparametric identification results, for which we provide methods to empirically test the key identifying assumptions and alternative...

We analyze efficient risk-sharing arrangements when coalitions may deviate. Coalitions form to insure against idiosyncratic income risk. Self-enforcing contracts for both the original coalition and any deviating coalition rely on a belief in future cooperation, and we treat the contracting...

Recent years have seen growing cases of data-driven tech mergers such as Google/Fitbit, in which a dominant digital platform acquires a relatively small rm possessing a large volume of consumer data. The digital platform can consolidate the consumer data with its existing data set from other...
