Feeding 9 billion people by 2050 on one hand, and preserving the erosion of biodiversity on the other hand, are two shared policy goals at the global level. Yet while these goals are clear, they are to some extent in conflict, because agriculture is a major cause of biodiversity loss, and the path...

We explore conditions under which a multiproduct firm can profitably turn itself into a platform by "hosting rivals," i.e. by inviting rivals to sell products or services on top of its core product. Hosting eliminates the additional shopping costs to consumers of buying a specialist rival's...

We study optimal income taxation in a framework where one's willingness to report his income truthfully is positively correlated with his type. We show that allowing low-productivity types to cheat leads to Pareto-superior outcomes as compared to deterring them, even if audits can be performed...

This paper shows that the two oil shocks that occurred in 1974-85 and 2003-15 inflicted sizable damage to total factor productivity (TFP) in France and Germany. These are resource-poor economies whose firms are importing most of their inputs of extractive commodities. The real prices they pay for...

Across societies, humans punish norm violations. To date, research on the antecedents and consequences of punishment has largely relied upon agent-based modeling and laboratory experiments. Here, we report a longitudinal study documenting punishment responses to norm violations in daily life (k = ...

Over the last decades, molecular signatures have become increasingly important in oncology and are opening up a new area of personalized medicine. Nevertheless, biological relevance and statistical tools necessary for the development of these signatures have been called into question in the...
