People conceptualize space using different spatial reference frames, based either in the body or the environment. Many studies attribute this cognitive diversity to spatial language, but their effects are confounded by differences across cultures and experimental tasks. Here we tested this...

We explore empirically the impact of the market sharing collusive practices that were implemented in the French public transportation industry between 1994 and 1999. We build a structural model of bidding markets where innovating firms compete for the market and have the ability to spread the...

Corporate green bond announcements generate positive abnormal stock returns. We suggest this might be because managers use green bonds to signal the profitability of the climate-friendly projects they finance. First, we build a signaling model of green bond issuance. It predicts that firms’...

We introduce and analyse the almost sure convergence of a new stochastic algorithm for the global minimization of Morse functions on compact Riemannian manifolds. This diffusion process is called fraudulent because it requires the knowledge of minimal value of the function to minimize. Its...

We examine pharmaceutical regulations and incentives for innovation from an international perspective, highlighting the public good nature of healthcare innovation and its cross-border diffusion. We summarize the empirical evidence on how push and pull incentives shape R&D investment,...

Oxytocin, a hormone linked to reproduction and health, may mediate life-history trade-offs across the human life course. Yet, how oxytocin naturally varies with age remains poorly understood. Here, working with the Tsimane, forager-horticulturalists of lowland Bolivia, we collected the largest...

Using a novel 15-year data set on surgeon adoption of a complex surgical innovation in the English National Health Service and an identification strategy based on surgeon mobility, this paper disentangles three channels of coworker influence on innovation diffusion: (1) peer network size, (2)...
