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)...

We analyze the optimal combination of direct and indirect taxes in the presence of tax avoidance. Proportional commodity taxes remain part of the optimal tax structure when avoidance is possible, even when the Atkinson–Stiglitz conditions hold. Taxing consumption, despite avoidance, enhances the...

We analyze bubbles and crashes in a model in which some investors are partially sophisticated. While the expectations of such investors are endogenously determined in equilibrium, these are based on a coarse understanding of the market dynamics. We highlight how such investors may endogenously...

Motivated by finding a way to deal with Compositional Data (CoDa) with or without zeroes in a unified way, we build upon the previous projective geometry viewpoint of Faugeras (2023) and use the tools provided by the exterior product and Grassmann’s algebra. These allow to represent higher...

Altruistic decisions are central to civic engagement and humanitarian efforts. However, altruistic behavior is often context-dependent rather than consistent—the same individuals who act generously in one situation may behave selfishly in another. Here, we review research on this phenomenon, which...
