Should Big Tech firms be banned from acquiring other firms? We address this question by developing a growth model with platform-based consumption. The platform supplies some products in the economy, and startups supply the rest, with the platform intermediating consumption of all goods in the...

What guides ownership intuitions, thoughts of the form “this thing x belongs to person A” ? Psychologists generally assume that human minds possess an implicit ownership theory, from which ownership intuitions are derived. But this mental theory is mostly an ad hoc stipulation. A more plausible,...

We study dynamic information provision to a present-biased decision maker (DM) who faces an experimentation problem. In our model, rewards arrive independently of the hidden state, so that under full information, beliefs remain constant prior to conclusive news arrival. Our main finding is that...

In many animal species, individuals acquire knowledge from others that enhances their survival and reproduction. However, among the many available exemplars, not all provide reliable information. Consequently, individuals tend to choose their exemplars selectively. One widespread pattern is a...

"Et si, grâce aux mathématiques, nous repensions la façon dont nous votons ? Etudier les modes de scrutin d'un point de vue mathématique permet de décrire des propriétés que ceux-ci devraient respecter. Cependant, un théorème important établi par l'économiste américain K. Arrow (Prix Nobel d'...

We conduct a meta-analysis of 82 randomized controlled trials across more than 20 countries to estimate the effects of interventions that provide instruction or information to parents about their child's education. These interventions are highly scalable in that they are low cost and delivered...

Large language models (LLMs) are increasingly deployed as agents in high-stakes domains like healthcare where optimal actions depend on both uncertainty about the world and the utilities of different outcomes. However, their decision logic is difficult to interpret. We study whether LLMs act like...

We present a novel approach to causal identification and estimation with large N and T panel data without external instruments. Existing approaches aim to extract and purge individual and/or period-specific factors from the outcomes and continuous treatments. They assume that the remaining...

Germany recovered from the Great Depression faster than any comparable economy - a gap that standard monetary and fiscal channels cannot explain. We provide causal evidence from a natural experiment: Nazi radio propaganda. Using quasi-random variation in radio signal strength across German labor...
